Evaporator Piping Components
Note: Make sure all piping components are between the shutoff valves, so that isolation can be accomplished on
both the condenser and the evaporator. "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
• Clean out tees
• Pipe strainer
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
• Clean out tees
• Balancing valve
• Pressure relief valve
To prevent evaporator damage, do not exceed 10 bar evaporator water pressure for standard units.
To prevent heat exchangers damage, install a strainer in the evaporator water inlet piping.
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
• Pipe unions
• Vibration eliminators (rubber boots)
• Shutoff (isolation) valves
• Thermometers
• Clean out tees
• Pipe strainer
• Flow switch
