Piping Considerations for Permanent Installations
An optional (or customer-installed) strainer on the COOLING WATER IN inlet is
recommended
The unit must have at least 16 psig (110 kPa/1.1 bar) water supply pressure to prevent
pump cavitation that can be caused by the water “flashing” to steam. To avoid damage to
the pump or other components, make sure that maximum supply pressure does not exceed
75 psig (517 kPa/5.2 bar).
Keep restrictions to a minimum by using proper inlet pipe sizing. If the water supply piping is
larger than ¾”, reduce the size at the unit. The table below contains the pipe sizes that are
used in the unit.

Common black pipe is recommended for permanent installations. TC110 Series water circuit
piping is primarily ferrous (iron) and reacts electro-chemically with non-ferrous metallic
materials such as copper. Some water contains dissolved minerals that greatly accelerate
the reaction between dissimilar metals.
Ferrous piping is recommended to minimize galvanic action. If piping must be copper, use
dielectric unions at the unit.

Piping Considerations for High Mobility Installations
Mobile TC110 Series systems must use high quality hose rated for at least 150 psig and
250°F (1034 kPa/10.3 bar and 121°C).
Quick disconnects may be used for mobility, although they cause a drop in pressure. If used,
they must be sized carefully to minimize pressure drop. Don’t use quick disconnects with
check valves unless absolutely necessary.
Non-relieving quick connect fittings or check valves on the water supply must have a
pressure relief piped to the drain.
Failure to do so could result in a dangerous over-pressure condition!
