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 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. If a
taste, odor or sediment problem is prevalent, try installing our
waste filter module, Part No. 73-15242-51-550, on the supply line.
4. Connect cooler to building supply line with a shut-off valve and
install a union connection between the valve and cooler
5. Electrical: 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.
6. This chiller has been designed for use with potable water and
includes an o-ring seal on the drain plug. This fitting should be
replaced if the unit is to be used with more aggressive fluids.
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. 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.
