Drain Fittings ST

Installation Instructions (valid for all drain fitting types)

1. Create a hole on the duct wall according to the required drain fitting size using a cone-cutter (see „dimensions“).

2. Insert the drain fitting from inside the duct and, on the outside, the funnel or washer and the nut. Tighten the nut until the duct wall is deformed enough to create a funnel-like area. Applying some grease between the nut and the fitting will ease this operation. Caution: do not over-tight the nut on the ST-K drain fittings, as the brass conical washer is less sturdy than the funnels of the other drain fitting types which are made of galvanized steel.

In case the drain fitting rotates when tightening the nut: a special flat area has been created on one side of the fitting. It provides a firm hold using pliers in order to prevent the fitting from rotating when the nut is tightened while preventing any damage to the threads.

3. The cap is only used if no drainage has been planned (please order separately).

4. On the ST-R drain fittings two markings have been created on the saddle funnel, allowing to align it with the axial direction of the round duct.

Maximum duct wallthickness: 1,5 mm

Holding-Wrench – Eases the Installation of the Drain Fittings:

The Holding-Wrench allows tightening the drain fittings easily without damaging the threads. It is also recommended to use this tool when a PTFE seal ring (to be ordered separately) is required to increase the drain fitting‘s liquid tightness.

The assembly is carried through as indicated above, excepting that the Holding-Wrench is used instead of the pliers. Please make sure that the lever faces the fitting‘s flat surface. Then tighten the nut using a standard or a pipe-wrench.


• Facilitate the manufacture of dampers: you only have to

build the blade and fasten it.

• The duct walls are clamped and stiffened between two pressed plates.

• Easy installation.

• Continuous variable position adjustment of the blade.

• Comfortable operation.

The duct wall is clamped between two pressed plates. When the red knob is tightened the damper plate is locked without any slack.

This knob is loosened for damper adjustment and tightened to lock it into position.

On large dampers this

washer can be replaced by an operating lever

Openings which allow to turn the

damper blade

The damper blade has to be manufactured according to size and rigidity requirements.

On this side the plates are clamped together by a spring tension and can be

rotated freely

Pivot pins are compressed on springs when you install the damper into the duct. When they are aligned with the pivot holes in the duct they spring out and position the damper.

Blade Manufacture Instructions

Depending on the stability requirements, either single or double blade dampers are suitable.

In both cases the sides have to be folded right-angled 20 to 25 mm for stiffening and fixing purposes.

Fixing the damper blade: Spot-weld the damper blade on the inner pressed plates. The center line marked on the inner pressed plate shows the position of the damper blade. Damper blades should be manufactured within a tolerance of 2 mm to prevent duct wall bulging or being pulled inwards on assembly. The dimension should be verified before fixing the second plate.

Cone cutters are very helpful for drilling the pivot holes:

KS 10 = 14 mm Ø, KS 25 = 20 mm Ø

To install the blade in the duct, com-press the spring loaded pivot pins and slide the assembly into the duct until the pivots spring out through the pivot holes.

Fix the outer plate with the locking knob so that the triangular arrow

shows the position of the damper blade. Then

fix the plate on the other side

Installation Instructions

Control Dampers KS


To adjust the damper, release the knob until the plates are no longer clamped. Adjust to the required position using the lever or actuator plate with reference to the arrow which is indicating the blade position. Then tighten the knob to lock the damper into position.

The fixing screw on the opposite side remains tightened during the adjust-ment of the damper, since the plates are pressed together by the force of the springs.

Operation

LIGHT DUTY DAMPERSA lever is not required to operate them. Rotate the actuator plate with your fingers, as depicted (only KS 25).

MEDIUM DUTY DAMPERSFor these kind of dampers the lever should be positioned centrally on the plate, as illustrated.

Dampers are also suitable for motor actuation.

In that case the knob must not be tightened too much since the blade should be able to rotate easily.

HEAVY DUTY DAMPERSThe lever should be positioned on one side to obtain maximum leverage.

• Assembly elements for the fabrication and installation

of tie bars.

• The duct wall is clamped between two rigid discs over

a large area for an optimal load distribution

• The tie bar is made of conventional ⅜” galvanized tubing (DIN 2440).

Installation Instructions1. Determine the position of the tie bars. If duct work is stiffened, position the tie bar at the intersection of the stiffening.

2. The overall length of the tie bar is equal to the clear internal duct dimensions. If the cross stiffening is external (as it can be found on positive pressure duct work), add 20 mm to the tube length. If the cross stiffening is internal (as it can be found on negative pressure duct work), deduct 20 mm from the tube length.

3. The tube length is the tie bar overall length minus 2 mm. Hammer in the expanding plugs flush with both ends of the tube.

4. Drill 7 mm Ø holes in the required locations.

5. Fit the tie bar with one disc on the inside and one on the outside on each end of the tube. Tighten the screws with a 5 mm Allen key to expand the plugs.

6. Crossing tie bars can be connected with a cross tie. Make sure that the tubes are straight before securing the cross tie.

• For the support and fastening of ductwork and other equipment.

• The special profile shape provides a high bending resistance.

• A range of accessories and ingenious details offer an

answer to practically any suspension requirements with only one system.

The MS Isolation Pads provide optimal sound proofing.

The slot in the Hanger Profile allows toinsert the Isolation Pads at any desiredposition.

The material around the oval holes is turned inside and provides extra rigidity in the hole area (also available withoutthe holes).

The high profile section provides a high bending resistance compared

to the necessary material, and consequently an optimal

price/loading capacity ratio.

The oval holes allow the passing of threaded rods or bolts, thus increasing

the installation possibilities

The MS Hanger Profiles have been initially designed to answer ductwork installation requirements. The variety of these requirements being relatively broad, the MS Hanger Profiles can also be used for other application fields such as heating and sanitary installations.

The loading capacity being a critical factor, three different profile sizes have been created, being able to support loads from a few kilos (small ductwork) to more important weights such as 4 meters wide ductwork, silencers, filters, accessories or other equipment. The loading capacity can also be multiplied by coupling several MS Hanger Profiles.

Finally, a few accessories give a greater flexibility to numerous suspension requirements. In an attempt to keep the number of parts to a minimum, each one of these accessories has been carefully designed to cover several combi-nation possibilities.

Dimensions and Load-bearing Capacities

All figures in mmScale 1:1

The loading capacity of hanger profiles used to support ductwork is generally limited by the deflection of the profile under load. According to the European Norm EN 12236, a deflection of max. 0,4 % of the profile length is allowed.

Only simple ductwork suspension cases as shown in fig. 2 can be described in a tabulation (fig. 3).

The tabulation shows the max. 1/2 duct weight which can be supported by the Hanger Profiles with a certain distance between the threaded rods, taking into considera-tion that the deflection of the Hanger Profiles must not be greater than 0,4 % of the distance between the threaded rods.

The values shown are only valid if the distance between the threaded rod and the duct wall is max. 30 mm!By increasing the distance between the threaded rod and the duct wall, the max. loading capacity decreases rapidly.

When uneven or otherwise critical loads are present, either a sophisticated calculation method or a field trial can provide correct answers.

When using the field trial method, the Hanger Profile type is selected by the installer. Then, if the deflection is found to be too important (that is more than 0,4 % of the length) it can be reduced by using a larger Hanger Profile type, coupling several profiles together or by installing a third threaded rod.

Hanger Profiles MS


The MS End Bracket is inserted as a connecting part between the Hanger Profile and the threaded rod.Advantages: - High loading capacity - Aesthetically pleasing - Independence from the profile holes.When only one duct is going to be suspended, the Hanger Profile section is cut 20 to 40 mm longer than the duct width. For all other applications, cut the Hanger Profile sections according to your needs.If isolation is required, first insert the Isolation Pads on both ends of the Hanger Profile.

The End Brackets are slightly tapered so that they wedge into the profile and must be hammered home hard up to the stop. To prevent the End Bracket from being damaged, the protective cap which is included in each sack of End Brackets, should be used.The End Bracket can be fitted into short profiles in a vertical position. Long Profiles should be put in a horizontal position against for instance a wall, in order to hammer in the End Brackets.

Max. threaded rod Ø for: End Bracket MS 3 = M8 End Bracket MS 5 = M10 End Bracket MS 8 = M12

If the maximum threaded rod diameters are used, no washers are needed. If smaller threaded rod diameters are used, corresponding washers must be installed.

If in some special cases the End Bracket is not sufficiently secured, it is possible to secure it in place with screws or rivets.

As an alternative to the End Bracket, the threaded rod can be passed through the oval holes of the Hanger Profile and fixed by a MS Clamp.

Max. threaded rod Ø for: Clamp MS 3 = M8 Clamp MS 5 = M10 Clamp MS 8 = M12

If the maximum threaded rod diameters are used, no washers are needed. If smaller threaded rod diameters are used, corresponding washers must be installed between the MS Clamp and the nut.

A more stable connection between Hanger Profile and threaded rod is achieved by using two MS Clamps and nuts.

Isolation Pads

At the end sections of the Hanger Profile the Isolation Pad can be easily inserted.

If the Isolation Pad has to be installed further along the Hanger Profile, it can be hammered on.

The use of MS Isolation Pads provides a cost effective solution if sound isolation is required.

Because the duct weight is mainly concentrated on the duct corners, the Isolation Pads installed at the corners have to support the most important loads. Because of its high loading capacity a rubber with 60° shore hardness has been cho-sen. The effectiveness of the Isolation Pad decreases rapidly when it is overloaded.

Normally only two Isolation Pads are required (one at each edge of the duct work).

On wide duct work, however, additional Isolation Pads must be installed to prevent the bottom of the duct from touching the Hanger Profile.

Length of the Isolation Pads: MS 3 = 60 mm MS 5 = 80 mm MS 8 = 100 mm

The bottom corners of the duct work greatly compress the Isolation Pads. Softer Isolators (foam rubber for example) may be compressed to such an extent that they become ineffective.

This graph shows to which extent the Isolation Pad is compressed depending on different loading capacities.

For safe fixation of Hanger Profiles to a wall, Wall Brackets are fastened to the wall using screws or plugs.MS 3 2 x M8MS 5 2 x M10MS 8 2 x M12The Hanger Profile is connected to the Wall Bracket using a hex-bolt going through the Wall Bracket and the End Bracket installed at the end of the Profile.

Caution: The Wall Bracket is not suitable for cantilever brackets (projecting supports). The Hanger Profile must be supported at both ends.

Max. loading capacity *of the connectionWall Bracket -Hanger Profile:

MS 3 = 1500 NMS 5 = 3000 NMS 8 = 4000 N

The position of the Hanger Profile respective to the wall can be from parallel up to a right angle, thus providing a 180° range of possibilities.

Please note that a position where the Hanger Profile is completely parallel to the wall is only possible when the Wall Bracket is fixed with only one screw to the wall. This consequently halves the maximum loading capacity.

Beam Clamps

Because of their design, the Beam Clamps can generally be installed on all common structural steelwork thickness.

For safety reasons the Beam Clamp should be installed in such a way that the bolt is in contact or only a small distance away from the beam.

Whenever possible, the Hanger Profiles should be installed on the structural beams.

The safety factor is increased when two Beam Clamps are installed.

• For the suspension of rectangular ductwork with

threaded rods.

• Sturdy construction with loadbearing capacity up to 1500 N

• Large supporting surface area prevents the edge of the duct from being deformed.


Installation InstructionsPress the AL Support Bracket tight against the duct wall and drill through the 5 mm guide holes to suit rivets or self-tapping screws. The threaded rod can be positioned either before or after the fixing of the Support Bracket on the duct wall.Sound isolation: If sound isolation is required, we recommend the use of SI Isolation Hangers for loads up to 1500 N, or the use of DB Ceiling Brackets.

Load-bearing Capacity and DimensionsThe two AL Support Brackets have the same sizes and differ only in the diameter of the hole for the threaded rod:length 37 mm, width 50 mm, height 37 mm. The load-bearing capacity always depends on the strength of the duct work, since the duct wall will buckle before the bracket deforms. With a duct wall thickness of 1 mm for instance the AL Support Bracket loading capacity is 1500 N*.

The shape of the Support Bracket is designed to distribute the load on the threaded rod and to hold it tight against the duct wall in order to ensure that the nut provides the main support.

The nut is partly under the edge of the duct and therefore supports the main load while reducing the strain on the threaded rod.

Installation InstructionsInstead of the standard bolts and nuts two AB Hanger Bolts are fitted in the holes of the duct´s bottom corner pieces.Care must be taken when tightening the bolts that the hole for the support threaded rod remains vertical. Only the bottom holes must be used, not only because it allows adjustment of the support rod, but also for safety reasons - the bottom corners can never be pulled out from the duct.

Sound isolation: With SI Isolation Hangers or DB Ceiling Brackets.If ducts have external insulation, the supporting rods can be approximately 5 cm longer and a Long Nut (please refer to section “GS Threaded Rods/LM Long Nuts“) or collar 30 mm long is installed instead of the normal nut. This enables the height of the duct to be adjusted even after it has been insulated.

- The surfaces must be dry and exempt from dust, separating agents and oils.- The most favorable application temperatures lie between +15°C and +30°C.- During the application make sure that the gasket is not elongated, otherwise the tensile loads might peel-off the gasket from the surface.

Application Instructions


• Established, single component, elasto-plastic butyl mastic sealant.

• Excellent adhesion, elasticity, and resistance against aging, temperature and chemicals.

• Available in cartridges or buckets.

Designation

Art. No. Description Content ApplicationF14V-1001 Butyl Mastic Cartridge 310 cm3 Ready-to-use mastic for manually operated gunF14V-1004 Butyl Mastic Bucket 5000 cm3 Ready to use mastic for the application with brush or spatula

Characteristics and Application Fields

- Single component, silicone-free, elasto-plastic butyl based sealing compound which can be painted over. Suitable for an application with a brush or spatula. Good adhesion to metals and plastic.- Product made of Butyl rubber, synthetic resins, mineral fillers and solvents (no toluene).- Color: grey.- Consistency: pasty.- Operating temperature: from -30°C to +100°C once set. Short-term up to +180°C.- Reaction to Fire: Before setting: Building Material Class: B3 (easily flammable). VbF A I, easily flammable. No longer inflammable after curing and thus no longer classified as a hazardous substance. Fire Resistance: not applicable Smoke Emissions: no information available- VDI 6022: Butyl mastic can be disinfected and fulfills the hygienic requirements related to its use in clean rooms and is in compliance with the VDI 6022 requirements for the application in HVAC ventilation systems.- Ideal for the usual sealing of seams, folds, and smaller joints on ventilation air ducts. - Also suitable for the tightening of flanges.- Builds, after approximately one hour, a skin which no longer sticks to the skin. The resulting viscous sealant remains flexible enough to cover slight movements of the parts to be tightened.

- The surfaces must be solid, clean and dry.- Enough mastic must be applied in the joints and areas to be tightened. Air-pockets should be avoided.- The sealant stripe must be as small as possible. For joints wider than 10 mm shrinkage cracking could appear.- Joints and exposed areas can be smoothened using one‘s fingers or a spatula moistened with dishwashing liquid.



Sealant


• For the protection of duct work during transport and site

storage.

• Works well on galvanized steel, stainless steel and aluminum.

• Does not leave sticky residues on duct work after removal.

• Tear and temperature resistant up to +60°C.

• The PE foil is environment friendly and can be recycled.

Characteristics and Applications

- High strength, full release, self-adhesive polyethylene film, which does not leave any sticky residues after removal.- Has been designed specifically for the requirements of the HVAC industry airducts.- Although it‘s uses are multiple, it‘s primary purpose is to protect the open ends of ductwork, fittings, and other HVAC products made of galvanized steel, stainless steel or aluminum from hard to remove dirt and debris, which often accumulate prior to final installation.- The ≈ 0,047 (+/- 10%) mm thick polyethylene foil is strong but at the same time soft and easy to apply.- Short-term weather resistant, and resists relatively harsh transport and storage conditions.

- The duct surfaces should be clean and dry before application.- Since the surfaces can vary depending on the material or surface variances, it is recommended, especially by sensitive surfaces, to test the Protective Foil on a small, if possible hidden area. METU shall not be liable for any consequential damages related to the use of this product.
