Installation Instructions
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.
7. For use with photo processing applications, adjust thermostat to warmer settings.
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 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.
NOTICE:
This water cooler must be connected to the water supply using a dielectric coupling.
