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 fl ushing 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 fl ush 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 fi lling 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.
