Cornelius R-134A manual Cleaning Condenser Coil, Replenishing CO2 Supply

11. Place Cooling Unit power switch in “ON”(up) position.

CLEANING CONDENSER COIL

(see Figure 3

CAUTION: The drop-in refrigeration assembly condenser coil and air filter must be cleaned every 30-days. Excessive accumulation of dust, lint, and grease on the air filter and coil will restrict air flow through the coil and cause refrigeration assembly to overheat. Operating

refrigeration system in an overheated condition will eventually lead to refrigeration compressor failure.

Area on top of hood must be kept free of obstructions at all times. Make sure nothing is stored on top of the hood. Clean condenser coil and air filter as follows:

1.Place Cooling Unit power switch in “OFF”(down) position.

2.Remove top screw from ground strap securing hood to Cooling Unit.

3.Remove acorn nut securing hood on Unit, then lift hood straight up to remove.

4.Slide air filter straight up out of the condenser coil frame side rails to remove.

5.Wash out air filter with water and detergent solution, the rinse with clean water and allow to air dry.

6.Vacuum or use a soft brush to clean condenser coil. If available, use low-pressure compressed air.

7.Clean dust and dirt from around top of the refrigeration assembly.

8.Install air filter on condenser coil by reversing removal procedure.

9.Install Cooling Unit hood and secure with acorn nut.

10.Install screw in hood ground strap to secure strap to hood.

11.Place Cooling Unit power switch in “ON”(up) position.

CARBONATOR WATER PUMP MAINTENANCE (OR AFTER WATER SYSTEM DISRUPTION)

WARNING: The carbonator water pump water inlet strainer screen and double check valve must be inspected and serviced at least once a year under normal circumstances, and after any disruptions (plumbing work, earthquake, etc.) to the water supply system that might

cause turbulent (erratic) flow of water through the system. A carbonator water pump with no screen or a defective screen in the strainer would allow foreign particles to foul the double check valve. CO2 gas could then back flow into the water system and create a health hazard in the water system.

The carbonator water pump water inlet strainer screen and double liquid check valve must be inspected and serviced at least once a year as described in WARNING note above. This procedure should be performed by a Service Person. Refer to step 8 of “Maintenance Schedule”.

REPLENISHING CO2 SUPPLY

WARNING: CO2 displaces oxygen. Strict attention must be observed in the prevention of CO2 (carbon dioxide) gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before

attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience tremors which are followed rapidly by loss of consciousness and suffocation.
