and off at 200 psi. The second fan or blower cycles on at 275 psi and off at 225 psi.

This safety feature shuts down the system if the water in the reservoir falls below a safe level.
Pump cavitation and freeze- up would otherwise occur.

An additional contact is provided to allow the remote starting or stopping of the Glacier Chiller
from a remote location. To use this feature, remove the jumper between terminals X1 and 1 on
TB2. Supply a switch or dry contact interlock connected in series between these two terminals.
Refer to the schematic glued inside the control enclosure door or the typical schematics in
