Installation Mechanical
“Piping components” include all devices and controls used to provide proper
water system operation and unit operating safety. These components and
their general locations are given below.
Entering Chilled Water Piping
• Air vents (to bleed air from system)
• Water pressure gauges with shutoff valves
• Pipe unions
• Vibration eliminators (rubber boots)
• Shutoff (isolation) valves
• Thermometers
• Cleanout tees
• Pipe strainer
• Flow switch
Leaving Chilled Water Piping
• Air vents (to bleed air from system)
• Water pressure gauges with shutoff valves
• Pipe unions
• Vibration eliminators (rubber boots)
• Shutoff (isolation) valves
• Thermometers
• Cleanout tees
• Balancing valve
• Pressure relief valve
CAUTION
Evaporator Damage!
To prevent evaporator damage, do not exceed 150 psig (10.3 bar)
evaporator water pressure for standard water boxes. Maximum
pressure for high pressure water boxes is 300 psig (20.7 bar).
Refer to digit 14 of the Model No. To prevent tube damage, install
a strainer in the evaporator water inlet piping. To prevent tube
corrosion, ensure that the initial water fill has a balanced pH.
Condenser Piping Components
“Piping components” include all devices and controls used to provide proper
water system operation and unit operating safety. These components and
their general locations are given below.
Entering condenser water piping.
• Air vents (to bleed air from system)
• Water pressure gauges with shutoff valves
