PWC-1000 Cooler

1. Introduction

The PWC-1000 line of point of use coolers are designed to give years of reliable service The cooler has 2 spigots that dispense filtered water at 2 different temperature levels – hot and cold temperature water. The main (cold-temp) tank holds one gallon of water and is constructed of stainless steel. The cold tank can be accessed for servicing the float mechanism and for cleaning by removing the cooler main top cover (see section 4).

The hot tank is made of stainless steel and holds ½ gallon. It is important not to turn on the hot tank when there is no water in it as this will damage the heating element.

The compressor is a sealed unit and is not serviceable in the field. The compressor can be replaced by a qualified refrigeration technician with proper tools and equipment. Please consult the factory if the compressor needs servicing. CAUTION: If the compressor has been stopped by switching it off or unplugging power, WAIT 10 MINUTES before turning the compressor on again. The compressor may stall

and burnout if powered back on without waiting.

The cooler makes clean water by filtration or by the reverse osmosis process. Water enters the back of the cooler and then passes through the filtration system. A feed water ball valve is Located near the filters and must be turned to the on position to allow the unit to make water. Electrical power is not required for the cooler to make purified water. CAUTION: The carbon filtration versions of the cooler (PWC-1000F) should not be used with water hardness over 7 grains because of lime scale build up on the heating element. If hardness is higher than 7 grains, softening of the feed water is recommended or another option is to install a “phosphate” filter to the filter system.

2. Cooler Set-Up cont.

2.4 Make feed water connection to cold water line. A self piercing saddle valve is provided.

2.5 Flushing carbon fines from carbon filter. Most carbon filters have fine particles of carbon material in the filter that will be swept into the water stream when the first water flows through the filter. Although not harmful, these carbon fines in the water are unsightly. Flush the carbon fines out of the filter before filling cooler tanks with the following procedure.

Feedwater connection (RO & filtration coolers

(For use on copper tubing)

Use supplied self piercing saddle valve. Connect to water inlet on cooler using 1/4” tubing. Clamp saddle valve over copper feed water line (cold water line on ly). Tighten needle valve until tube is pierced. Ret ra ct

needle 1 -2 turns to start water f lo w.

)

2.6 Remove outlet line of carbon filter (bottom)

2.7 Attach 3 feet of ¼” tubing to the carbon filter outlet port (flush tubing)

2.8 Place flush tubing in bucket to catch water carbon fines.
