CAUTION
Equipment Damage!
To prevent damage to water piping, do not overtighten
connections. To prevent equipment damage, bypass
the unit if using an acidic ushing agent.
Note: Make sure that all piping is flushed and cleaned
prior to starting the unit.
Vents and Drains
Install pipe plugs in evaporator and condenser water
box drain and vent connections before filling the water
systems.
To drain water, remove vent and drain plugs, install a
NPT connector in the drain connection with a shutoff
valve and connect a hose to it.
Evaporator Piping Components
Note: Make sure all piping components are between
the shutoff valves, so that isolation can be accom-
plished on both the condenser and the evapora-
tor.
“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

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 box-
es 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 corro-
sion, ensure that the initial water ll 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.
