pressure of 15 psi (103.4 kPa) at a pressure reducing station consisting of two pressure reducing valves. The new steam

equipment includes the two heat exchangers HEX-01 and HEX-02 and the steam humidifiers associated with Air

Handling Units AHU-02 and AHU-03. Condensate is returned from the new steam equipment to the existing

condensate return system by a new Condensate Return Unit CRU-1 with two condensate return pumps

A. A new Steam Main conveys steam at 150 psi from the existing steam main in the existing Mechanical Room to the

new Mechanical Room.

B. A Steam Pressure Reducing Station with two pressure reducing valves PRV-1 and PRV-2 in the new Mechanical

Room reduce the steam pressure from 150 psi to 15 psi. A normally closed bypass valve is provided on the steam

pressure reducing station so that the steam flow may be manually controlled in case of failure of the pressure

reducing station.

C. A Pressure Relief Valve is provided on the new 15 psi steam main to automatically relieve pressure in the steam

main in case it builds up above a safe pressure limit. The steam relief line is piped to discharge the steam to

outdoors above the roof level.

D. A Branch Steam Supply Line Connection conveys 15 psi steam from the new main steam piping to each item of

equipment including the three humidifiers for AHU-02 and AHU-03, and the two steam to heating water heat

exchangers HEX-01 and HEX-02.

E. The Steam to Heating Hot Water Heat Exchangers HEX-01 & HEX-02 transfer heat from the steam system to

the 30 % glycol (antifreeze) solution used for the hydronic heating system.

P. Air leaving the exhaust plenum enters a Concrete Trench that runs outside of the north side of the Mechanical

Equipment Penthouse. The concrete trench is lined with Styrofoam board insulation.

Q. The Main Exhaust Duct Riser conveys the air leaving the concrete trench up to the fume exhaust fans on the roof.

The duct riser is located inside a shaft and is externally insulated with aluminium jacket.

R. The concrete trench conveys the exhaust air from the stainless steel exhaust plenum to the Fume Exhaust System on

the roof. The fume exhaust system consists of three high plume dilution type Laboratory Exhaust Fans EF-02A, EF-02B and EF-02C mounted on top of a common Laboratory Bypass Exhaust Air Plenum with two openings,

each with an air intake hood and Motorized Dilution Air Intake Damper CD-02-AB &CD-02-CB that control the

flow of dilution air into the suction side of the three Laboratory Exhaust Fans. As the total airflow from the fume

hoods decreases (e.g. when most of the VAV exhaust dampers are at or near their minimum air flow setting) then

more dilution air is drawn into the total exhaust air flow.

S. The three exhaust fans discharge the air upwards at high velocity through Discharge Cones that increase the

velocity of the air as it leaves the exhaust system to discharge the air as high as possible.

T. A Motorized Intake Damper is provided on the air intake to each fan so that each fan may be isolated from the

connected into the existing non potable water system.

A new 100-mm DCW line for emergency cooling is tied into the chilled water piping to be used in case the water chiller system

fails. When the DCW emergency backup system is in use, the water flowing through the chilled water piping system is drained

out to a 100-mm hub drain located in the new Mechanical Room. Reduced pressure backflow assemblies are provided on the

drain lines to prevent backflow of water into the potable DCW system and to control the pressure leaving the DCW piping system

into the drain. For further information refer to the previous description for the chilled water piping system.

A branch DCW line is provided with its own reduced pressure backflow assembly for the irrigation system. A control valve is

provided on the main irrigation water supply line to automatically control the flow of water to the irrigation system based on a

schedule.

Isolation valves are provided in the ceiling on the branch lines that connect into the main DCW line for the new addition. The

isolation valves make it possible to service the DCW piping and equipment in one area of the building without closing off the flow

of water to other parts.

28

Sanitary Drainage

The Sanitary Drainage System serves all the plumbing fixtures and floor drains. Vent lines, piped through the roof allow the

vent gases to exhaust to atmosphere unobstructed and enable free flow through the sanitary drain lines. The sanitary drain

connections from floor drains, lavatories, sinks and other plumbing fixtures are each provided with a trap. Each trap has a U-bend

or P-bend that fills with water each time the fixture is used. The water in the trap provides a seal to prevent unwanted gases from

the sanitary drain lines from coming out through the plumbing fixtures into the occupied areas. Trap seal primers are provided for

the floor drains to automatically fill them with water periodically to ensure that they do not dry out.

Each plumbing fixture is connected to a sanitary drain line that runs in the ceiling of the floor below the fixture or under the floor

slab. The sanitary drain lines are sloped downward towards the main 100-mm sanitary drain line for the building addition that

runs underground and discharge into a sanitary sump located outside the northwest corner of the building addition adjacent to

the storm sump. There is a duplex sanitary sump pump that discharges sanitary effluent through a pumped discharge line that

connects to the 150-mm main sanitary drain line that connects to the municipal sanitary sewer system. .

Mechanical Equipment Starting Procedures

For additional information regarding individual items of equipment, refer to Section 3.0: Equipment Shop Drawings and Maintenance Data. For additional information on the operation of equipment, refer to Section 1.2 Description of Systems.

Disclaimer Section 1.3 The manual is intended to provide general guidelines only for reference by the building operators and maintainers. The responsibility for retaining knowledgeable operating and maintaining personnel to operate and maintain the mechanical equipment and systems rests with the Owner. It is up to the operating and maintenance staff to determine the optimum temperature control system set points to maintain building conditions at comfort levels suitable for the actual occupants of the building and to achieve the most efficient energy performance based on their experience and on guidance from the building Owner, who sets policies regarding safety, energy efficiency and building comfort.

Air Handling Units

The air handling unit supply air fans may be electrically isolated by using the local disconnect switches. When changing the

filters or servicing any components inside the unit, de-energize the air handling unit fans for safety and limit the possibility of

damaging the equipment.

Ventilation: Outdoor air for ventilation is very important for building pressurization and for good air quality in the building.

If some of the occupied rooms become noticeably stuffy during times when the building is occupied, check to ensure that the

supply fans are operating, that the motorized outdoor air dampers are open and that there is flow of air to the supply air

diffusers.

Control Settings: The DDC system controls the system to match the actual req

Space Temperatures: The heating system is designed to maintain space temperatures in occupied rooms at 21 C (70 F)

during occupied periods. Space temperatures in occupied areas should be monitored regularly to notice any significant

change from normal.

Filters The air handling system filters should be changed on a regular basis, eg about every eight to ten weeks throughout the year

when the building is being used. Otherwise, the outdoor air volumes will decrease and there will not be adequate air supply

for ventilation and free cooling in the rooms.

The dirt loading of air filters varies according to the cleanliness of the air being handled through the system. This may vary

from one season to another. The actual pressure drop through the filters may be determined by using the installed static

pressure gauges. As the filter bank loads with dirt over several weeks, the air pressure drop through the filters gradually

increases. Following are guidelines for the pressure drops for clean and loaded (dirty) filters. These are based on the

assumption that the air volume across the filter bank is equal to the peak design airflow rate.

LUBRICATION GUIDE

Conditions

The following information provides general guidelines for obtaining optimum performance from the various types of fan and

motor bearings. Because there are unique operating conditions for each individual system it is up to the building operators to

determine what is best for each situation.

The following conditions influence the required frequency of lubricating fan and motor bearings:

1. Cleanliness: Fan systems that are located in areas exposed to dirt-laden air require more frequent lubrication.

2. Moisture: If the ambient air has high humidity levels or if there is any direct water splash, the bearings require

more frequent lubrication.

3. Temperature: Higher temperature conditions require more frequent lubrication.

4. Load Conditions: Abnormally high load conditions have an effect on the recommended lubrication procedures.

Higher speed fans and motors require more frequent lubrication.

5. Hours of Operation: The frequency of lubricating bearings depends on the average weekly hours of operation.

Obviously a system that operates continually requires more frequent lubrication compared to a system that is

operated periodically according to a time schedule.

6. Types of Bearings: Fan bearings may be permanently lubricated sealed type, Ball bearing type, solid pillow block

spherical roller bearings or split pillow block spherical roller bearings. Motor bearings may be grease or oil

lubricated.

In some cases the equipment manufacturer provides specific recommendations for lubricating bearings and these may be

Equipment Survey Identification of Equipment Types

The first step in establishing a project specific lubrication schedule is to survey all of the fan and motor equipment in the

building to identify the types of fan and motor bearings, whether each is grease or oil lubricated and the system conditions

that influence lubrication requirements. Once this has been completed, a specific lubrication schedule may be developed

using the general lubrication guide on the following page.

Permanently Lubricated Sealed Fan Bearings For most normal operating conditions, pre-lubricated ball bearings require no lubrication for at least 7 to 10 years of

operation.

Grease Lubricated Ball Type Fan Bearings For clean, dry operating conditions, and operating temperatures between 30 ºC and 60 ºC change grease at 3 to 6 month

intervals, (or as per chart below) using Shell Alvania No 2 grease or equivalent. Add grease using low pressure grease gun,

with the fan wheel slowly rotated manually (if possible) until some purging occurs at the seals. Note the condition of the old

grease that appears and adjust lubrication schedule accordingly. Do not over grease.

Following is a general guide for re-lubricating based on fan speed and shaft size.
