13. Hydra Icebank Control Go/No Go Test
The Polaris has both thermostat and icebank / tank level control.
When operated as an icebank unit:
The thermostat will be energised continuously and use to display the bath temperature. The refrigeration
system will be controlled by the icebank coverage of the probe.
When operated as a Glycol unit:
The thermostat in conjunction with the Hydra control will control the refrigeration and display the tank
temperature. The icebank / level control will be energised continuously to provide low tank level protection.
For both systems, the liquid line probe from the Hydra control provides High Temp protection for the
refrigeration system.
The following test is to determine if the icebank / level control is operating correctly.
Warning
240VAC is present on terminals N, A, ON 1, ON 2 terminals.
Work should only be performed by fully trained & certified
Electrical, Plumbing & Refrigeration Technicians.
