protective device until you have located and corrected the problem. Refer to the Unit
Wiring Diagram and Service Manual for the proper procedure and wiring checkout.
The text of step-by-step procedures uses language and symbols, which refer to the
electrical supply as single phase. Three-phase equipment should be given equally
cautious consideration when service is necessary.
Again, we want to stress that it is essential that WHENEVER ELECTRIC POWER is
applied to the motor-compressor, the terminal PROTECTIVE COVER must be properly
in place.
Servicing refrigeration and air conditioning systems can be dangerous, and extreme
caution in all respects should be exercised by the personnel servicing such equipment.
The precautions discussed in this bulletin deal only with those dangers associated with
VENTING TERMINALS.

The air-cooled condenser should be cleaned on a regular basis; depending on the
environment the chiller is installed in., check often.
The water level should be maintained as close to the level as marked on the water
sight glass. You can damage the refrigeration system by the water being at a low
level, and will affect the efficiency of the unit.
Caution: The compressor receivers and water pump could be hot enough to injure
one touching these components.
