INSTALLATION

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 ysed 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. Water inlet is 1/4" (6 mm) O.D. tube. Contractor to supply

connections as required.

3. Connecting lines to be of copper, thoroughly flushed to remove all

foreign matter before being connected to cooler. If flushing does

not remove all particles, a water strainer should be installed in

supply line

4. Connect cooler to building supply line with a shut-off valve and

install a union connection between the valve and cooler

5. Electrical: Make sure power supply is identical in voltage, cycle,

and phase to that specified on cooler serial plate. Never wire

compressor directly to the power supply.

START-UP

1. Open supply line valve.

2. Purge air from all water lines by operating bubbler valve of

fountain to which cooler is connected. Steady stream assures all air

removed.

3. Rotate fan to insure proper clearance and free fan action.

4. Connect to electrical power.

TROUBLE SHOOTING & MAINTENANCE

Temperature Control: Factory set at 50°F (+/- 5°) under normal

conditions. For colder water, adjust screw on item no. 3 CW.

Ventilation: Cabinet louvers and condenser fins should be

periodically cleaned with brush, air hose or vacuum cleaner.

Excess dirt or poor ventilation can cause no cold water and

compressor cycling on the compressor overload prctector.

Lubrication: Motors are lifetime lubricated.
