INSTALLATION
1. When mounting unit in an open area, to insure proper ventilation,
maintain a 4" (102mm) clearance from cabinet louvers on each side
of cooler . When mounting unit in a cavity or behind a wall maintain
minimum space of 4" (102mm) on each side, 4" (102mm) on the top
and a depth of 12" (305mm).
2. Water inlet is 1/4" (6 mm) O.D. tube. Contractor to supply the
connections as required.
3. Connecting lines to be of unplated copper, thoroughly ushed to
remove all foreign matter before being connected to cooler. If
ushing does not remove all particles, a water strainer should be
installed in supply line. This cooler is manufactured in such a manner
that it does not in any way cause taste, odor, color or sediment
problems.
4. Connect cooler to building supply line with a shut-off valve and
install the in-line strainer between the valve and cooler.
5. Electrical: Make sure power supply is identical in voltage, cycle,
and phase to that specied on cooler serial plate. Never wire
compressor directly to the power supply.
6. This chiller has been designed for use with potable water ONLY.
START-UP
1. Open supply line valve.
2. Purge air from all water lines by operating bubbler valve of
fountain to which cooler is connected. Steady stream assures all
air is removed.
3. Rotate fan to insure proper clearance and free fan action.
4. Connect to electrical power.
TROUBLE SHOOTING & MAINTENANCE
Temperature Control: Factory set at 50°F (± 5°) under normal
conditions. For colder water, adjust screw on item no. 9 in
clockwise direction.
Ventilation: Cabinet louvers and condenser ns should be
periodically cleaned with brush, air hose or vacuum cleaner.
Excess dirt or poor ventilation can cause no cold water and
compressor cycling on the compressor 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”.
