Installation
For correct and safe installation, please read these instructions completely.
DANGER
• All Installation work must be performed by an authorized service personnel.
• Disconnect electrical supply serving the Installation area to reduce risk of electrocution.
• Unit not suitable for installations where water jets could be used.
WARNING
• Shut off water supply serving the Installation area to reduce risk of water damage.
• Installation area must have minimum required clearances and ventilation for safe operation.
• Never wire compressor directly to electrical supply.
CAUTION
• Hose-sets are not to be used for connecting to water mains.
• Tools/Items required but not provided.
o Safety Glasses
o Protective Gloves
o Hex drives.
o Water Shut-off Valve with 3/8" (9.5mm) compression outlet.
o Fasteners for wall type.
This unit can be installed underneath a commercial or industrial sink, in
a cabinet not less than 36" (914mm) wide (inside dimension). Two air
openings with a minimum of 40" square (1016mm/square) each, minimum
of 75% open area, must be provided in the cabinet. One opening must
be in the overhang of the toe space, the other opening near the top of the
cabinet. The remote unit must be installed with a minimum of 3"(76mm)
clearance between the unit and the rear wall of the cabinet. It can be in-
stalled ush against either side wall of the cabinet. The side louvers which
are not against the cabinet must not be blocked by objects located within
4" (102mm) of the louvers. In addition, a minimum of 1 to 2" (25 to 51mm)
clearance must be provided between the toe space air opening and front
of the unit.
Water inlet and outlet are 1/4" (6 mm) O.D. tubes with connectors sup-
plied.
Connecting lines to be of copper, thoroughly ushed to remove all foreign
matter before being connected to cooler.
Connect cooler to building water mains with a shut-off valve and install
a 3/8" O.D. (10mm) unplated copper tube between the valve and cooler.
Remove burr from outside of water line. Insert water line into tting until it
reaches a positive stop, approximately 3/4" (19mm).

Wiring Instructions
1. Turn off electrical supply to chiller circuit
2. Remove top cover to gain access to electrical box
3. Join electrical wire to unit using 3/8” cable clamp
connector or appropriate conduit connector
4. Connect ground wire to ground screw (provided)
5. Connect black wire to 230VAC
6. Connect white wire to Neutral line
7. Replace top cover and turn on electrical supply.
Start-Up
1. Open water shut-off valve.
2. Purge air from all water lines by operating bubbler valve
of fountain to which cooler is connected. Steady water
stream assures all air is removed.
3. Rotate fan to insure proper clearance and free fan action.
4. Connect to electrical supply.

Service
For proper and safe servicing, please read these instructions completely.
DANGER
• All Service and Maintenance must be performed by an authorized service personnel.
• Disconnect electrical supply to the unit before any service work to reduce risk of electrocution.
• Shut off water supply serving the unit before any service work to reduce risk of water damage.
CAUTION
• Tools/Items required but not provided, for Servicing:
o Safety Glasses
o Protective Gloves
o Hex drives.
Service: Adjustments
1. Temperature Control: Water temperature is factory set at 50ºF ± 5º (10ºC ± 5º) under normal conditions. For colder water, adjust screw on
item no. 10 in clockwise direction.
Service: Inspection/Cleaning
• Inspect Water Chiller twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc. and reassembly and return to service practices.
2. Condenser Fan Motor: Conrm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service personnel
replace.
3. Ventilation: Cabinet louvers and condenser ns should be periodically cleaned with a brush, air hose or vacuum cleaner. Cleaning should be
done twice each year or more frequently if needed due to environment. Excess dirt or poor ventilation can cause no cold water and
compressor cycling on the compressor overload protector.
4. Water Flow: Conrm proper water ow. If water ow is slow, inspect lter or inline strainer for restriction. Replace lter cartridge if required.
Disassemble inline strainer and clean if required.
5. Lubrication: Motors are lifetime lubricated.
Replacement Parts: Parts List
*INCLUDES RELAY & OVERLOAD. IF UNDER WARRANTY, REPLACE
WITH SAME COMPRESSOR USED IN ORIGINAL ASSEMBLY.
NOTE: All correspondence pertaining to any of the above water cool-
ers or orders for repair parts MUST include Model No. and Serial No. of
