Elkay ER30 Series Installation Instructions

INSTALLATION INSTRUCTIONS
Note: Danger! Electric shock hazard. Disconnect power before servicing unit.
Uses HFC-134A refrigerant
NOTICE: This water cooler must be connected
to the water supply using a dielectric coupling.
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.
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 fi tting should be replaced if the unit is
to be used with more aggressive fl uids.
3. Connecting lines to be made of copper. Thoroughly fl ush all lines to remove all foreign matter before connecting to cooler. If fl 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. Electrical: Make sure power supply is identical in voltage, cycle, and phase to that specifi ed on cooler serial plate. Never wire the compressor
directly to the power supply.
6. For use with photo processing applications, adjust thermostat to warmer settings.
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.
