NOTES:
1 . Figures 1 and 2 are required piping for proper water regulation and distribution through ClimaCool modular chillers .
2 . Module order and incoming/outgoing water flow as shown in both Figure 1 and 2 can be set up as either a left-to-right or right-to-
left configuration .
3 . Condenser Hydronic Circuit shown . Piping configurations are similar for the chilled water hydronic circuit .
4 . For condenser and chilled water (evaporator) inlet/outlet location dimensions, refer to Module Dimensional Data .
5 . A flow switch (supplied by others) is a required safety device for ClimaCool modular chillers on the chilled and condenser water
circuits .
6 . Maximum water flow rates for both evaporator and condenser water header systems in one bank of modules is 1000 GPM . Field
Piping Reverse Return - (Preferred 1 to 5 modules) Required for 6 to 7 Modules (Figure 2)
7 . The chilled water piping on each module is pre-insulated at the factory with ¾” closed cell foam rubber . Insulation (3/4”) on the
chilled water header connection flanges is to be applied in the field by the installer, after the modules are bolted together on site .
