CAUTION: READ MANUAL BEFORE OPERATING COOLING UNIT
– Input power must be rated for 230 VAC at 50 or 60 Hz.
– Use water or water/glycol as coolant.
– Run the cooling unit at the correct coolant level,
otherwise cooling capacity will be reduced.

DescripTion
The WL 3000 cooling unit is intended to remove heat from a liquid circuit. The coolant can be either water or a
mixture of water and water-glycol (antifreeze). Water circulates in a closed loop between the ambient cooling system
and a cold plate at the heat source. Heat is removed from water by an air-cooled heat exchanger. The capacity

4.1 heaT exchanger
In order to achieve maximum cooling capacity, the heat exchanger of the cooling unit must be kept clean.
Check the heat exchanger every three months for cleanliness. If cleaning is required, perform the following:
1. Disconnect the cooling unit from the main power source.
2. Remove the side cover.
3. Clean the heat exchanger with compressed air, a damp cloth or shop vacuum.
4. Mount the side cover.
