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.
are compatible with 316 stainless steel, prior to making
connections to the ClimaCool chiller. There are certain
necessary components that should always be installed
in both the chilled water and condenser water systems.

accordance with applicable codes and standards.

proper readings.

not exceeded. To prevent operation of the chiller without
both the chilled and condenser water circuits. Place one
on each side, downstream of the strainers on the inlet and
outlet of a straight pipe, as close to the module as possible.
Do not put in an elbow on the outlet.
Note: Evaporator and condenser
sides both require sensors of equal pressure ranges.
Pressure Taps
The installing contractor must provide access ports for
pressure gauges for both the condenser and chilled water
systems. A ¼” pressure tap is required on the inlet and the
Water Isolation Valves
It is recommended to provide bank water isolation valves
for proper isolation and maintenance of the chiller, pump
Strainers – Minimum 60 Mesh Screen Required
ClimaCool chillers utilize brazed plate heat exchangers
which are extremely sensitive to debris. Therefore, it is
mandatory that all condenser and chilled water systems
include a strainer with a minimum of 60 mesh screen for
proper ltration. The strainers must be installed as shown in
ClimaCool’s warranty does not cover and does not apply to
products which have defects or damages due to freezing
of the water supply, an inadequate or interrupted water
supply, corrosives or abrasives in the water supply, or
improper or inadequate ltration or treatment of the
water supply.
Chiller/Heater System Water Header Bypass
A bypass is required for any chilled water/evaporator, hot
variable pumping. The bypass must be piped in such a way
Figures 9 and 10 on page 12. 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
