INSTALLATION
1. This unit is intended for remote installation only. It is important to insure proper ventilation. A minimum of 6 inches
(152mm) to the front must be maintained, and 6 inches (152mm) to the rear of the unit.
2. 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.
3. Installer to provide air gap at condenser water outlet to comply with local plumbing specifications.
4. Connecting lines to be made of copper. Thoroughly flush all lines to remove all foreign matter before connecting to
cooler. If flushing does not remove all particles, a water strainer should be installed in the supply line.
5. Connect cooler to building supply with a shut-off valve and install a union connection between the valve and the
cooler.
6. Electrical: Make sure power supply is identical in voltage, cycle, and phase to that specified on cooler serial plate.
Never wire the compressor directly to the power supply.

START-UP
1. Open supply line valve.
2. Purge all air from all water lines by operating bubbler valve of fountain to which
cooler is connected. A steady stream flow assures that all air is removed.
3. Rotate fan blade to assure proper clearance and free action.
4. Connect to proper electrical power.
IMPORTANT! INSTALLER PLEASE NOTE:
The grounding of electrical equipment such as telephone, computers, etc., to water
lines is a common procedure. This grounding may be in the building, or may occur
away from the building. This grounding can cause electrical feedback into a water
chiller, creating an electrolysis which causes a metallic taste or an increase in the
metal content of the water. This condition is avoidable by using the proper materials
indicated below. Drain fittings which are provided by the installer should be plastic to
electrically isolate the chiller from the building plumbing system.
TROUBLE SHOOTING & MAINTENANCE
Temperature Control: Factory set for 50°F water (± 5°) under normal conditions. For
colder water, adjust screw on item no. 9 clockwise.
Ventilation: Cabinet louvers and condenser fins should be periodically cleaned with a
brush, air hose, or vacuum cleaner. Excess dirt or poor ventilation can cause no
cold water and compressor cycling on the overload protector.
Lubrication: Motors are lifetime lubricated.
Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free plug
which utilizes an o-ring seal. To remove plug from cooler, relieve water pressure,
pull the collar towards the fitting and pull the fitting off the tube. To install plug,
push fitting straight onto tubing until it reaches a positive stop, approximately 3/4.
