OPERATION OF QUICK CONNECT FITTINGS

1.  Insure proper ventilation. 

In fully recessed drinking fountains be sure condenser faces louver panel and is

     within 1/2" (13 mm) of louver panel when panel is in place.

2.  Water inlet is 3/8" (10 mm) O.D. unplated tube connector.

  Contractor to supply connections as required.

3.  Connecting lines to be made of unplated copper. 

Thoroughly flush all lines to remove all foreign matter before

     connecting to cooler.

4.  Connect cooler to building supply 

with a shut-off valve and install a 3/8" (10 mm) water line between the valve

     and cooler. Remove burrs from outside of water line. Insert water line into bulkhead union until it reaches a

     positive stop, approximately 3/4" (19 mm).

5.  Electrical:  Make sure power supply is identical

 in voltage, cycle, and phase to that specified on cooler serial

     plate. Never wire the compressor directly to the power supply.

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 (± 5°) under normal conditions. For colder water, adjust screw

          on item no. 5.

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 connectors which utilize an o-ring

          seal. To remove tubing from the fittings, relieve water pressure, push in on gray collar while pulling on the

          tubing. To insert tubing, push tube straight into fitting until it reaches a positive stop, approximately 3/4”.

INSTALLATION

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.
