INSTALLATION

1. When mounting unit in an open area, to insure proper ventilation,  

  maintain a 4" (102mm) clearance from cabinet louvers on each side 

  of cooler . When mounting unit  in a cavity or behind a wall maintain 

  minimum space of 4" (102mm) on each side, 4" (102mm) on the top    

  and a depth of 12" (305mm).

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

   connections as required.

3. Connecting lines to be of unplated 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. This cooler is manufactured in such a manner  

   that it does not in any way cause taste, odor, color or sediment   

   problems.

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

   install the in-line strainer 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. 

6. This chiller has been designed for use with potable water 

ONLY.

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 is 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. 12 in

    clockwise direction.

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 protector.

Lubrication: 

Motors are lifetime lubricated.

Actuation of Quick Connect Water Fittings: 

Cooler is provided 

    with lead-free connectors which utilize an o-ring seal. To remove 

    tubing from the fittings, relieve water pressure, push in on gray 

    collar while pulling on the tubing. To insert tubing, push tube 

    straight into fitting until it reaches a positive stop, approximately

    3/4”.
