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 ush 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).
Electrical: Make sure power supply is identical in voltage, cycle, and phase to that specied 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 con-
tent of the water. This condition is avoidable by using the proper materials indicated below. Drain ttings 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 ns 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 ttings, relieve water pressure, push in on gray collar while pulling on the
tubing. To insert tubing, push tube straight into tting 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 ow assures that all air is removed.
3. Rotate fan blade to assure proper clearance and free action.
4. Connect to proper electrical power.
