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 .
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) unplated 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).
NOTE: DO NOT SOLDER TUBES INSERTED INTO THE STRAINER AS DAMAGE TO THE O-RINGS MAY RESULT.
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.
