The liquid cooling system is an efficient closed loop, pressurized system. Prior to
operation the cooling system must be properly prepared for operation and bled to
remove trapped air. Instructions for cooling system preparation can be found in Section
2.
The heat exchanger and pump module unit operates on either 208-240 VAC, 50/60 Hz
or 380-415 VAC 50/60 Hz. The operating voltages and frequencies should be provided
at time of order. The number of heat exchanger fans will vary with model number.
