A bypass is required for any chilled water/evaporator, hot
water/condenser (heating load) and source water side
(geothermal, cooling tower or closed circuit cooler) with
variable pumping. The bypass must be piped in such a way

Figures 9 and 10 on page 13. The purpose of the chiller/heater
system bypass is to prevent deadheading of the pumps
when all of the internal unit valves go closed as well as allow

of modules remaining for that duty. For instance with an
SHC OnDemand heat pump system with four (4 ) modules,
if you designate one (1) module for heating bypass and one
(1) module for cooling bypass, the system now only allows
a maximum of three (3) modules for heating or three (3)
modules for cooling. Also, with a module acting as a bypass
increased wear of heat exchangers may be caused by

bypass kits must be installed on each water source loop
and controls are integrated with the CoolLogic software.

Water Piping
As with any water system, it is important that the system be
clean. The pipe work installer must remove weld scale, rust
and contamination during pipe work fabrication. The system
