Installation and Application Information
piping, respectively, (see Figure 7) These evaporators do
not have drain or vent connections due to their construction.
Purge air from the water system prior to unit start-up to
provide adequate flow through the evaporator.
• A suitable support for piping, separate from the unit, to
eliminate weight and stress on fittings and connections.
• An expansion tank and regulating valve to maintain water
pressure.
• Suitable mechanical connections. All evaporators have.
• OGS type grooved water connections (adhering to AWWA
C606) optionally with flanges. PVC piping should not be used.

It is recommended that the field-installed water piping for the
chiller include:
• Temperature
sensors
at
connections.
• Water pressure gauge connection taps and pressure gauges
on evaporator inlet and outlet connections to measure water
pressure drop.
• Shut-off valves to isolate the unit from piping during unit
maintenance.
• Minimum elevation changes and bends to minimize pressure
drop.
• Vibration eliminators on supply and return water lines to
reduce transmissions to the building.

Polyolester oil, commonly known as POE oil, is a synthetic
oil used in many refrigeration systems and is present in this
Clima Flex product. POE oil, if it ever comes in contact with
PVC/CPVC, will coat the inside wall of the PVC/CPVC pipe
causing environmental stress fractures. Although there is
no PVC/CPVC pipe in this product, keep this in mind when
selecting piping materials for your application as system
failure and property damage could occur. Consult the pipe
manufacturer's recommendations to determine suitable pipe
applications.

• Thorough flushing of system water piping prior to making
connections to the unit evaporator.
• Insulation of the piping, including a vapor barrier, helps
prevent condensation and reduces heat loss.
• Periodic water analysis and chemical treatment of the
evaporator loop water is recommended immediately after unit
start-up.
NOTE: Failure to comply with these measures may result in
performance and reliability problems.
