Safety
DANGER
• Please read these instructions completely before starting the installation or performing any service. Failure to follow the instructions and
safety precautions in this manual can result in serious injury or death.
• After installation, keep these instructions in a safe location for future reference.
• Electric supply must be identical in voltage, cycle, and phase to that specied on nameplate.
• A means for disconnecting electrical supply to the unit must be incorporated in the xed wiring in accordance with wiring rules. This is to allow
electrical disconnection of the unit from electrical supply after installation.
WARNING
• For use with clean, clear potable drinking water only. Do not use with water that is microbiologically unsafe or of unknown quality without
adequate disinfection before the system.
• Installation and connection to water and electrical mains must be in compliance with local and national laws.
• All Installation and Service work must be performed by an authorized service personnel.
CAUTION
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory, or mental capabilities or lack
of experience and knowledge if they have been given supervision or instructions concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without
supervision.
• To prevent a metallic taste or increased metal content in the water due to an electrolysis process caused by electrical feedback from the
grounding of electrical equipment to water mains, connect to the water mains using a dielectric coupling.

Installation
For correct and safe installation, please read these instructions completely.
• 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.
DANGER
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 1/4" (6.4mm) Socket Wrench or Flat Head Screwdriver
o Water Shut-off Valve
o Fasteners for wall type.
Installation Steps
1. It is important to insure proper ventilation. For remote
installation a minimum clearance of 6 inches (152 mm) to
the front must be maintained, 1 inch (25 mm) each side,
3 inches (76 mm) to the rear above the unit. Wall grille
EG-1 or EG-2 to be used when unit is inserted into an
enclosure. Install unit as close as possible to wall grille.
A 6 inch (152 mm) clearance beyond the front of the wall
grille is required for adequate air circulation.
2. This chiller has been designed for use with potable water
and includes an o-ring seal on the drain plug. This tting
should be replaced if the unit is to be used with more
aggressive uids.
3. Connecting lines to be made of copper. Thoroughly ush
all lines to remove all foreign matter before connecting
to cooler. If ushing does not remove all particles, a water
strainer should be installed in the supply line.
4. Connect cooler to building supply with a shut-off valve
and install a union connection between the valve and the
cooler.
5. For use with photo processing applications, adjust
thermostat to warmer settings.
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
Start-Up
1. Open water shut-off valve
2. Purge air from all water lines by operating bubbler valve of fountain to which chiller is connected. Steady water stream assures
all air is removed
3. Rotate fan to insure proper clearance and free fan action
4. Turn on electrical supply
Water Mains Connection
A) 3/8” (9.5mm) O.D. Tube. Water Inlet to
Chiller
B) Building Water Mains
C) Water Shut-off Valve (not provided)

DANGER
CAUTION
• Tools/Items required but not provided, for Servicing:
o Safety Glasses
o Protective Gloves
o 1/4" (6.4mm) Socket Wrench or Flat Head Screwdriver
1. Temperature Control: Factory set for 50ºF ± 5º (10ºC ± 5º) water under normal conditions. To adjust water temperature, turn screw on Item
No. 14 clockwise for colder, counter clockwise for warmer.
Service: Adjustments
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.
6. Actuation of Quick Connect Water Fittings: Chiller is provided with
lead-free plug which utilizes an o-ring seal. To remove plug from
Chiller, relieve water pressure, pull the collar towards the tting and
pull the tting off the tube. To install plug, push tting straight onto
tubing until it reaches a positive stop, approximately 3/4”(19mm).
