The grounding of electrical equipment such as telephone, computers, etc., to water

lines is a common procedure. This grounding may be in the building, or may occur

away from the building. This grounding can cause electrical feedback into a water

chiller, creating an electrolysis which causes a metallic taste or an increase in the

metal content of the water. This condition is avoidable by using the proper materials

indicated below. Drain fittings which are provided by the installer should be plastic to

electrically isolate the chiller from the building plumbing system.

Temperature Control: Factory set for 50°F water under normal conditions. To

adjust water temperature, turn screw on Item No. 8 clockwise for colder, counter
clockwise for warmer.

Ventilation: Cabinet louvers and condenser fins should be periodically cleaned with

a brush, air hose, or vacuum cleaner. Excess dirt or poor ventilation can cause no

cold water and compressor cycling on the overload protector.

Lubrication: Motors are lifetime lubricated.

Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free

plug which utilizes an o-ring seal. To remove plug from cooler, relieve water

pressure, pull the collar towards the fitting and pull the fitting off the tube. To install

plug, push fitting straight onto tubing until it reaches a positive stop, approximately

3/4.

IMPORTANT! INSTALLER PLEASE NOTE:

TROUBLE SHOOTING & MAINTENANCE

START-UP

1. Open supply line valve.

2. Purge all air from all water lines by operating bubbler valve of fountain to which

cooler is connected. A steady stream flow assures that all air is removed.

3. Rotate fan blade to assure proper clearance and free action.

4. Connect to proper electrical power.
