Water Piping

Piping Connections
CAUTION
Equipment Damage!
To prevent equipment damage, bypass the unit if using an acidic
flushing agent.
Make water piping connections to the evaporator and condenser. Isolate and
support piping to prevent stress on the unit. Construct piping according to
local and national codes. Insulate and flush piping before connecting to unit.
Use grooved pipe connectors for all water piping connections. Evaporator and
condenser water inlet and outlet sizes and locations are shown by the unit
submittals and in Figure 9 through Figure 14. The designation in the tables
corresponds to the compressor frame code followed by the evaporator shell
code followed by the condenser shell code as given in the unit model num-
ber, digits 6, 7, 14, 15, 21 and 22. Table 10 gives additional water connection
information.
Reversing Water Boxes
All water boxes may be reversed end-for-end. Do not rotate water boxes.
Remove the sensors from the wells before removing the water box. Com-
plete the water box switch and replace the sensors. See Figure 9 through Fig-
ure 14 for correct orientation of the water inlet and outlet.
If the water boxes are reversed, be sure to properly rewire the water temper-
ature sensors in the control panel.
NOTE: Be certain to replace water boxes right-side-up to maintain proper
baffle orientation. Use new o-rings.
