Coolant plumbing
The chiller must not be installed more than 65 feet above the heat exchangers and cryro compressor. The chiller
pumps can deliver up to 165 feet of head. The heat exchangers and cryro compressor are rated at 230 feet
maximum. If the chiller is mounted more than 65 feet above the heat exchangers and cryro compressor, the
maximum allowable pressure on the heat exchangers and cryro compressor may be exceeded. Consult the
factory for installations requiring the chiller to be installed more than 65 feet above the Heat Exchanger. The
maximum equivalent linear feet of
2”
piping which may be installed external to the chiller is 500ft.

NOTICE
Exceeding recommended plumbing lengths can increase system pressure beyond
the capabilities of the pumps and can cause the pumps to supply less than the
required flow rate for proper operation. Consult the factory if recommended
lengths are to be exceeded.
NOTICE
Do not allow the fluid pumps to run dry. This will damage the pump seals and
will not be covered under warranty.
To install connecting plumbing between the chiller and process:
1.
Remove all caps at each plumbing port on the chiller.
2.
Pipe installation should adhere to ASME B1.20.1 for best practices.
3.
Ensure that all plumbing is routed in an orderly fashion and free of kinks.
4.
Fully open all valves (if present) on plumbing lines.
