Unit Leveling
NOTE: The electrical panel side of the unit is designated
as the “front” of the unit.
1. Check unit level end-to-end by placing a level on the
chiller structure (compressor frame for example).
2. Adjust to within 5 mm of level front-to-back.
Water Piping
Piping Connections
To prevent equipment damage, bypass the unit if using
an acidic flushing agent.
Make water piping connections to the evaporator
and condenser. Isolate and support piping to prevent
stress on the unit. Construct piping according to local
and national codes. Insulate and flush piping before
connecting to unit.
The chilled water connections to the evaporator are to be
grooved-pipe type connections. Do not attempt to weld
these connections. Refer to submittal for dimension of
tube stub for grooved connection. Refer to submittal for
dimension of tube stub for grooved connection.
To prevent damage to chilled water components, do not
allow evaporator pressure (maximum working pressure)
to exceed 10 bar.
Reversing Water Connections is prohibited
It is critical to keep the factory layout for water
connections. Therefore reversing water connections may
lead to functional disorder.
NOTE: Dimensions of tube stub for grooved connection
are included in submittal drawings.
Vents and Drains
Install pipe plugs in evaporator and condenser water
connections drain and vent connections before filling
the water systems. To drain water, remove vent and drain
plugs, install a NPT connector in the drain connection
and connect a hose to it.
Water Treatment
WARNING: Do not use untreated or improperly treated
water. Use of untreated or improperly treated water may
result in equipment damage.
The following disclamatory label is provided on
each unit:
The use of improperly treated or untreated water in this
equipment may result in scaling, erosion, corrosion,
algae or slime. The services of a qualified water
treatment specialist should be engaged to determine
what treatment, if any, is advisable. The warranty
specifically excludes liability for corrosion, erosion
or deterioration of the manufacturer’s equipment.
The manufacturer assumes no responsibilities for the
results of the use of untreated or improperly treated
water, or saline or brackish water.
