INSTALLATION
STEP 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).
STEP 2:
Water inlet is 1/4” (6mm) O.D. tube. Contractor to supply the connections as
required.
STEP 3:
Connecting lines to be of unplated copper, thoroughly flushed to remove all foreign
matter before being connected to cooler. If flushing 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.
STEP 4:
Connect cooler to building supply line with a shut-off valve and install the in-line
strainer between the valve and cooler.
STEP 5: Electrical:
HCR8 (115V/60HZ/5.0 AMPS) and HCR8.50 (220V/50HZ/2.0 AMPS).
Make sure power supply is identical in voltage, cycle, and phase to that specified on
cooler serial plate. Never wire compressor directly to the power supply.
STEP 6:
This chiller has been designed for use with potable water
ONLY
.
START-UP
STEP 1:
Open supply line valve.
STEP 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.
STEP 3:
Rotate fan to insure proper clearance and free fan action.
STEP 4:
Connect to electrical power.
TROUBLESHOOTING & MAINTENANCE
TEMPERATURE CONTROL:
Factory set at 50°F (±5°) under normal conditions. For colder
water, adjust screw on item no. 12 in clockwise direction.
VENTILATION:
Cabinet louvers and condenser fins 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 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”.
