3—Before assembling the sections, thoroughly clean the nipple ports and push nipples with an acceptable solvent. Make sure thereare no burrs around the outside edge of the Nipple ports.
4—Apply large diameter rope gasket to groove provided in section. Using Peerless ‘Rope Adhesive” provided, apply a coating to thegroove as an adhesive and then apply rope. See Figure #3. DO NOT USE SAME BRUSH USED FOR APPLYING NIPPLE SEALER.THIS WILL AVOID ThE POSSIBILITY OF CEIlING FOREIGN MAIlER INTO THE NIPPLE PORTS WHICH COULD CAUSE LEAKS OR BROKENSECTIONS.
S—Do not use oil on nipples or in nipple ports when assembling sections. This will cause sections to draw hard and nipples to leak.Spread a thin coating of Peerless Nipple Sealer in the nipple ports, NEVER ON NIPPIIS. Follow instructions printed on can.
6—Inseri nipples in ports and tap lightly on the edge with a non-metallic hammer. Make certain nipples are clean, free at burrs and straight
7—Pface intermediate section on foundation and allow nipples in back section to enter nipple ports. See Figure #4.
C
B—Insert draw rods through nipple ports with large cast-iron washers on each end of the rods. See Figure #5.
9—Attach draw-up clamps with jaws on long end of the rods. See Figure #5. On the other end at the rods, wrought washers andnuts may be applied (the sections are to be drawn by the HAND ASSEMBLY METHOD. If the sections are to be drawn up bythe HYDRAULIC JACK ASSEMBLY METHOD, then the jacks are attached to the opposite end of the rod. See Figure #6. Thefollowing are the instructions covering both methods of assembly.
I. HAND ASSEMBLY METHODS
a. BEFORE STARTING DRAW, OIL THE ThREADS AND BETWEEN THE NUTS AND WASHERS TO ELIMINATE AS MUCH FRICTION ASPOSSIBLE.
I,. Tighten hex nuts (See Figure #5) to draw sections together. Draw all three nipples evenly until four small pads on thecorners of each section just touch. II washers, nuts and threads are oiled frequently, the sections should draw easily.if the draw is hard, look for cocked nipples, dirt in the nipple ports or burrs on the nipples or around the nipple parts.
c. Apply rope to groove as described in Paragraph 4 above and put next intermediate section in place. Draw up in the samemanner and continue until all sections are assembled. Be sure to oil threads, nuts and washers on each draw.
d. The draw rods are now used as the tie rods. The rod5 are excessive in length for draw up purposes. It is necessary toremove 5” from one end of the rods in order to adapt them For tie rod purposes.Insert the tie rods in the lugs on the end sections, using the wrought iron washers and nuts only on each end.
e. Check to make certain that alt the small pads are drawn iron to iron and the push nipples have been drawn straight.
I, Tighten the hex nuts on the tie rods until hand tight.

b. Close valves on pumps (See Figure #6) and pump each jack evenly until spacer pads on all sections just touch. Periodiccheck of space between spacer pads should be made to assure an even draw,c. Open valves on jack pumps. Remove jaws, cast iion washers, jacks and draw rods. Place the nett set of sections inplace (mnimum of four sections) and proceed with steps (B), and (9) . (a) and (b) See Figure #7.d. Repeat this procedure until the last intermediate and front sections are assembled. The Front section may be a part ofthe last group ol sections.
Place large Cl. washars on one end and attach jacks. On the opposite end ol the drawand 9” extension piece to each draw rod. See Figure #8 and Figure #9. Tighten coup-Place CI. washers on end of rods with nuts and washers and proceed w.th final draw up.
e. Boiler is now completely drawn up. Remove draw rods and use as tie rods as described in 9 .

C — AIR FOR cOMBUSTION AND VENTILATION
I—Be certain adequate facilities are available to provide air for satisfactory combustion and ventilation.
2—Appliances Located in Unconfined Spaces.
a, Installations In unconfined spaces with conventional construction and larger areas such as basements, the supply of air brcombustion and ventilation can usually be considered adequate.
3—Appliances Located in Confined Spaces
a. IF all air for combustion and ventilation is to come from within the building, two openings, one near the ceiling and one near thefloor of the boiler room shall be provided wilh the minimum free area of each opening equal to 140 sq. in. per gallon oF oIl burned.b. If all air For combustion and ventilation is to come from outside the building; two openings, one near the ceiling and one near thefloor of the boiler room shall be provided with the minimum tree area of each opening equal to 35 sq. in. per gallon ci oilburned.
If ducts are used to convey the air, areas of 35 sq. in. per gallon of oil burned for vertical ducts or 70 sq. in. per gallon ofoil burned for horizontal ducts are to be provided. Ducts shall have the same area as the free area of the openings to whichthey are connected.

INSTALLATION
SELECTION
The Series LA and LE pumps are designed for working pressures up to 500 -
psi and are required to develop 25” mercury vacuum at 0 psi on factorytest. While these pumps win develop as high as 27 of vacuum, it issound engineering to avoid extreme vacuum whenever possible. Selectpipe size to reduce line friction loss to a minimum. On transfer service, place pump as close to supply tank as conditions will permit,and eliminate the use of foot valves or check valves in the suctionline whenever possible. The LA and LE pumps are self priming and particularly suited to handle liquids of 35 SSU to 1000 SSU viscosity.Higher viscosities can be handled at reduced speeds. It is importantthat the piping used in connecting the pump be clean and free of chipsor scales.
:iaEraIIlS and tables show an dimensions necessary to position theTuthill LA and £2 pump in your application. Consult us in selectingthe proper pump and size of motor, giving us all the following in!or—mation:

INSTAllATION AND SERVICE INSTRUCTIONS
ci FOR SERIES LA — LE PUMPS
GENERAL DESCRIPTION
The Ththifl Series LA-I.E is a compact, highly efficient, positive displacement3 rotary internal gear type pump with mechanical seal. Builtin five sizes, it provides capacities from 20 to 360 gallons per hourand pressures up to 500 psi and is available with 2—bolt flange in theLA Series and 3—bolt flange in the LE Series. Optional mounting feetare available. It is multi-directional in rotation and designed fordirect drive at standard motor speeds, with modifications availablefor indirect drive.
PUMPING PRINCIPLE
These pumps employ the Tuthill internal gearprinciple which is based upon the use of arotor, idler gear and a crescent—shaped partition that is cast integrally with thecover. (See accompanying figure.) Thus3only two moving parts comprise this effi
C cient pumping element. Power is applied tothe rotor and transmitted to the idler gearwith which it meshes. The space between theoutside diameter of the idler and the insidediameter of the rotor is sealed by the crescent. When the pump is started, there is anincrease in volume as the teeth come out ofmesh. This creates a partial vacuum, drawing the liquid into the pump through thesuction port. The liquid fills the spacesbetween the teeth of the idler and rotor andis carried past the crescent partition tothe pressure side of the pump. When theteeth mesh on the pressure side, the liquidis forced from the spaces and out throughthe discharge port.
SEAL
The seal is a device to prevent leakage between the stationary pumpbody and rotating drive shaft. A rotating lapped surface is attachedto the shaft by an elastomer bellows. This rotating face is springloaded to nib against a stationary lapped surface in the housing plugbushing. The clearance between these two surfaces is so minute thatresistance to flow is great enough that fluid will not leak out andair will not be drawn in.
COUNflRCLOCKWIS! ROYATiDH
-1-
Mt thOU Ut UXIVINU
Direct motor drive through a flexible coupling is the most satisfactorymethod.
Th NOTE: LA and LE puoms can be driven in either direction of rotation.
Q The seal chamber coimminicates with the neutral zone and therefore the seal is subjected to one-half of the discharge pressure.
Viewing the pump from the shaft end, the inlet port is on theright-hand side for clockwise rotation, on the left—hand sidefor counter-clockwise rotation.
Pumps with built—in relief valves are uni-directional. Therefore, rotation, clockwise or counter-clockwise, facing the shaftend, must be specified.
1. All pump and motor units are properly aligned at the factory.However, misalignment may occur due to abuse or conditions beyondour control.
2. Pipe strains often force the pump and motor shafts out of alignment. See that all piping leading to the pump is properly supported by wall brackets. Do not expect the pump to act as a pipesupport.
3. Provide for proper expansion of pipes when handling hot liquid.4. Series L pumps are not designed to take end thrust toward the cover
Provide sufficient clearance, 146” to 1/8” between couplinghalves with shafts in closest operating position, to allow forend wear in the driving shaft.
5. Never align the pump and motor supplied with pin type couplingwithout first removing the pins.
6. Iever depend upon sight or feel for freeness in aligning a pump.
IA and LE pumps should be filled with oil at installation and shouldnever be allowed to run dry.
STRAINER PROTECTION
Strainers are used to remove contathinating particles from the hydraulicsystem and every Ththill pump should be protected from these particlesby a strainer in the suction line.
1. Strainer size and mesh of screen is determined by rate of flowand viscosity of fluid. Consult strainer nnufacturer for re—conunendat ions.
2. Never use a strainer with a built—in automatic by-pass on thesuction line set to open under 30” Hg. vacuum.
3. Install strainer according to arrows or flow designation.4. Have strainer accessible for servicing.5. Use a duplex type where shutdown during service is not permitted.6. Provide a vacuum gage in the suction line for determining when
the strainer requires cleaning.7. Make certain strainer baskets are properly reinforced so as not
to collapse under 30” Hg. vacuum.
Series LA—I.E pumps should always be installed with both ports pointinga upward to insure proper priming. If it becomes necessary to install the\!3Y pump with the ports pointed to the side, then the top port should be the
suction,,prt. When the pump is installed above the supply tank, an inverted U bend should be incorporated in the suction line close to thepump to trap liquid in the pump for priming.

DISAS5EIsLy OF SEAL
The seal assembly of the LA and LE pump may be changed without dis—assembly of the rest of the pump.
1. Place the pump in vise3 shaft facing up, so that one jaw gripsacross the two ports. Do not tighten excessively as pumphousing may be distorted.
2. Inspect shaft at keyway, flat or drive tang. Any burrs willinterfere with removal of housing plug bearing assembly.
3. Remove housing plug with face tyte spanner wrench (availablefrom Ththifl as part No. 0L506).
U. Remove the seal from shaft. The rubber boot will be bonded tothe shaft, so it is necessary to push down on the seal to breakthis bond. Grasp the metal outer shell with any suitable deviceand pull the seal assembly upwards. The spring and washershould also be removed.
5. The 3OLk through 1LA and 3OLE through 1LE pump assemblies havea snap ring on the shaft to back up the seal assembly. Do notremove this snap ring unless you are completely disassemblingthe pump. The 2LA and 21E pumps do not have a snap ring. A
- step on the shaft is used as the seal back up.o. Remove stationary seal face from housing plug by pressing out
from opposite side.7. If damaged, remove the 0—ring from 0.0. of housing plug.

DISASSEMBLY OF PUMP
Seal assembly must be remed before disassembly of pump. Also removesnap ring on shaft on 301A through 1LA and JOLE through ThE.
Mark cover and body of the pump for proper reassembly Remove capscrews, cover, idler and rotor from housing.
INSPECTION
Check pump housing, rotor, idler gear, idler pin and crescent forwear, chipped or broken teeth.
Housing bore and rotor 0.0. may be checked for wear by positioningrotor in the housing and check for clearance in the bearing. Theshaft must turn freely without any detectable side play. Any sideplay will require replacement of the housing, rotor or both. Ifboth housing and rotor require replacing, it IS economically advisable to replace the pump.
ASSEMBLY OF PUMP
The following must be carefully followed when pump is reassembled:
1. Clean all parts thoroughly using great care to eliminate alldirt.Install rotor in pump body.Apply gasket to cover. Use new gasket if old one is damaged.Place idler gear on pin in cover assembly.Place cover assembly with gear on pump. (Align matching marksfor proper location.)Install cover cap screws. Pull down gradually and alternatefrom a screw on one side to one on the opposite aide.
7. Install snap ring on shaft.

NO Oil. IS DE.1EID.
a. Suction lift too high for vapor pressures of liquidpumped. While Ththill pumps will develop as high as27 inches of vacuum, it is good engineering practiceto reduce the vacuum to a minimum.
b. Bad leaks in suction line or port passages can be detected by submerging pressure line from discharge sideof pump into a pail of oil, where the air will be seenin the form of bubbles.
c. Pump shaft not rotating.Coupling defective — tongue and groove or gear notengaged.
CAPACITY IS TOO LOW.
a. Suction lift too high.b. Air leaks in suction line.c. Suction line too small.
Q Can be detected by installing a vacuum gauge directlyat the pump suction. The maximum vacuum at the pumpsuction should never exceed 15 inches of mercury. Itis necessary to keep below 15 inches, not because ofthe inability of the pump to handle a higher vacuum,but primarily because of the vaporization that isliable to take place at a higher vacuum. Vaporizationcaused by higher vacuums will generally result in capacity drop—off.
d. Pump speed too slow.e. Strainer too small or obstructed.f. Suction pipe or port not immersed in the liquid deep
enough.g. Piping improperly installed, permitting air pocket to
form in pump.h. Increased clearances or wear in the pump will sometimes
cause the pump to deliver an insufficient supply of liquid.

AMTROL AX and “L” SERIESEXTROLC EXPANSION TANKS
WHY AN EXPANSION TANK IS NECESSARYIN HOT OR CHILLED WATER SYSTEMSAs waler lemperalure increases so does its volume. Theexpansion tank accepts this excess while keeping systemptessuro within design limits. When the system cools, thewaler hold in the expansion lank returns. This means thatthe toIlet and liii valves act only as salew devices. Undueoperations of either should be examined.LOCATION OF EXTROL EXPANSION TANKSThe AMTROL expansion lank may be placed in any cowvenient position within the mechanical room (or building).II will work equally welt In either vertical or horizontal position. ii multiple lanks are installed, they should all be onthe same level. Unless desired, it Is not necessary toThe’ a tanks directly over boiler as with conventional lanks.
As with any expansion lank, ills recommended that theEXTROL is connected to the suction side of the pump.This will prevent the pump head From becoming subtracthe which may result in entry o( air and vapor formation athigh points in the system.By connecting tank on boiler return, displacement ofcoolest system waler into tank is Insured reducing energywastage. Low pressure drop components such asseparators and boilers may be placed between point orconnection and pump suction ii desired. Sy5tem designwilt dictate the feasibility vi this.Natural convection losses and the entry at air into tank areeliminated by connecting to the side or underside of mainpipe. Any potential air traps in piping connecting tank tosystem should be vented.

AIR SIDE CONNECTIONS — NONECheck EXTROL air charge using air valve at lop at tankbalore entry ci waler. The pressure should be equal tothe minimum system pressure required to till the systemand provide adequate positive pressure at top.
a. EXTROL must be isolaled during pressure testing ofsystem. This requires complete closing or the systemIsolation valve and it is recommended that this valvebe so tagged.
b. After the system isolation valve is securely closed, it itrecommended that the union between the lank and thesystem be slowly opened and that the liquid bedirected to a floor drain, if possible. Caution should beexercised so as not to drain system liquid onto anyarea that could be damaged.
c. The L-series tanks are equipped with an air valvelocaled on top ol the tank when the lank is installed mavertical position. This air valve is protected by a 1 ½”NP]’ ptug. Removal of this plug allows access to the airvalve. Using standard type airgauge (such as used Inthe automotive tire industry and the domestic wellindustry) one can then check the precharge pressureas with a standard automotive tire.
d. The precharge pressure can be reduced by simplydepressing the Internal valve pin of the air valve andreleasing the air precharge to desired pressure. Pro-charge pressure can be Increased by adding compressed air.

AIR PURGERSToday’s smaller, more efficient boilers for heating systems permit useof smaller tube or piping, smaller radiation, and high-head circulatingpumps. In these compact systems1 the problem of trapped air is ofcritical Importance if optimum system pressure, performance and lifeare to be realized.
AIR in the System• City water contains air in solution. This air in a water system consists ofabout 80% nitrogen (including a small mixture of other gases) and 20°/ooxygen. The oxygen is more readily absorbed in solution and carried throughthe system combIning with metallic surfaces to formoxides— corrosion.• Eventually a system’s air consists only of nitrogen, unless more air entersthe system, either in gaseous form or when make up water Is introduced. (• Undissolved air collects in the form of aIr bubbles at the top of vertical andhorizontal pipes and system components. When syslem water flows at Ihe rateof 1.5 to 2 feet per second or more, the air bubbles are carried through thesyslem and inhibited from rising.• Since the air is kept in contact with the water it can be absorbed. Absorptionis dependent upon temperature and pressure. Hotter water holds less air insolution than colder water. Water at lower pressures hold less air in solutionthan at hIgher pressures. SInce pressure and temperature in a systemconstantly change, depending on location and operating cycle, the water’s airholding capacity constantly varies.• When the air-holding capacity of lhe water is exceeded, air is released toForm bubbles again. These bubbles contain water vapor as welt as air and theirsize increases rapidly as they rise to the top ol the system. The amount of thewater vapor in the bubbles is proportIonal to the temperature Increase, thepressure decrease and the increase In bubble size. The amount of’water vaporIn a bubble may be many times greater than the amount of air.• Experience has proven that these gas bubbles are not carrIed, as may beexpected, back down 10 the boltom of the system where both the air and thewater vapor would be reabsorbed. In fact, they cause the pervasive problemsrelated to trapped air In a system: btockage and binding of terminals resultingin noise, inefliclent operation, and energy waste. The related loss of pumpperformance and corrosion ci equipment create expenstve maintenance andreplacement problems.

OPERATION
This American Automatic Air Vent has been designed totusc, on any hydronic or waler service system where prasuiadoes nai exceed 150 PSI and Icmperaiure is no greater than240°F, I should be installed in an accsible location atthe high points of the wsiom.
INSTALLATION
In a hydronic healing system, air removal can be accomp‘ tished most efticlently by installing a No. 705 Vent with a
procerly sized Air Purger or Air Separator. The purgerseparates the ar from the water end diverIs Ilto the Ventfor quick and automatic removal. A NPT lapping isprovided on the Vent lot this connection,The W’ tapping at the top of the No. 106 Vent accerns asaloly drain line br discharging any moisture that may becontained in the air as ills vented.
Since any vent may occasionally require cleaning when thesystem contains dirt or sludge, it is common procedure toinstall a gate valve to isolate the vent. The No. 105 Vent maybe cleaned simply by removing the flange bolts, lifting GUIthe inner assembly and washing oil the strainer. Allow 6”clearance above Iho lop ol the No, 706 Vent for removal althis assembly,

sisteni Is in opera’n. W2tr will flow Into thu systeiai .ir iii it is full and under pressure. Note: Series with FastflU and Purge LeverW valves are equipped with a unIque and simple “fast fill and purge levW. . . whichpermits rapid tilling of the system . . . and sustained flow for air purging.When the lever Is raised to the vertical positIon ft pushes a removable “Push Rod”down. This manually forces the valve to a wide open position for maximum flow. Reluming the lever to its normal position releases the tension on the rod permitting thevalve to maintain normal system pressure. Caution: Always observe the Boiler Pressure Gauge when using this feature. Using this feature with the Purge Valve closed canresult In over pressurizing the system or exceeding the Pressure Safety Railer Valvesetting. Over pressirization can result in a water discharge from the Relief Valve. Thisfeature can be disabled to prevent tampering or accidental misuse of the fast fill featureby simply unscrewing the fast fill lever cap and removing the push rod.
2. The regulator is set to deliver water to the boiler at approximately 15 lbs. pressure. This pressure is sufficient fora 3 story building. To reset the reducing valve (or higher pressure (when the pressure Is not sufficient to lift thewater to highest ra&stion):A. Calculate the number of feet fmm the regulator to the top of highest radiation.S. Multiply this number by 0.43 and addS lbs. iNs wTh give the pressure required to raise the water to the highest
radiator and keep the system under pressure.3. To reset the regulator valve:
Remove the fast fill lever cap. and loosen the lock nut. To raise the reduced pressure - slowly turn the adlustingscrew clockwise until the system gauge indicates the pressure required. To lower the reduced pressure - turnthe adjusting screw counterclockwise. After completing adjustments, tighten the lock nut and replace the fast flillever cap.
Hole: Watts Is not responsible for boiler failure on boilers without low water cutoffs.
IMPORTANTAnnual inspecilon of all water system safely andcontrol valves istequired and necessary. Regularinspection, teiting and cleaning assures maximumlife and proper produci function.

Servicing:The strainer screen should be serviced at least twice a year.This series Is a new development for standard capacity domesticwater regulation service. it has special unitized construction whichconsists of the seat, disc and stem assembly, and strainer screen alltogether In one unit for complete replacement maintenance.To clean or replace parts:
1. Close the shutoff valve upstream of the regulator.2. Bleed pressure from system.3. Loosen and remove the fast fill cap. Remove the spring cageand all parts above the diaphragm.4. Loosen and remove the diaphragm lock nut and lock washer,pressure plate and diaphragm from the valve stem.5. Unscrew seat cylinder 1mm body and remove entire assembly.6. Prior to reassembly flush valve to remove sediment.7. After repairs are completed reassemble In reverse order.
Troubleshooting:A dripping Pressure Safety Relief Valve can bean Indication that theFeed Water Pressure Regulator requires service.
tmpodanttThe pressure Safety Relief Valve is on the system to protect againstexcessive water pressure only. The function ot the valve is torelease any excess pressure from the system caused by thermalexpansion of the water. Therefore, do not be alarmed at waterdrippage as the valve Is do1ng what it Is designed to do. Thisdrippage will not prevent the natural buildup of temperature inthe boiler because the valve operates on pressure only. The valvewill open when the gauge pressure reaches 30 lbs.To avoid water damage or scaldIng due to valve operation, a drainpipe must be connected to the Pressure Safety RelIef Valve andron to a safe place of disposal.Never plug the discharge of a pressure safety relief aIvelOther possIble causes should also be examined prior to servicIng the regulator.Some other possible causes are a water logged air cushIon tank,an over pressurized diaphragm style air cushion tank, an undersized air cushIon Lank and, on systems with a domestic watercoil, a leak in the tankiess coil.
Periodic Inspection of the system by a qualified plumbing and heating technIcIan is recommended. Corrosive water condItions, exIremely high water temperatures, unauthorized adjustments or repair could renderthe valve Ineffective for the service intended. Regular inspection and cleaning of all water safety and control valves assures maximum life and proper product and system function.
