6. 5 COMPRESSOR BURN-OUT

To determine if a burn-out has occurred, perform the following
steps:
1 Disconnect the unit from power source.
2 Remove wiring from the compressor terminals.
3 Using an ohmmeter, check for ground between the
terminals and the compressor housing. If a reading exists, the
compressor has shorted to ground.
In this case compressor must be replaced as per following
steps:
4 Recover the refrigerant using an approved refrigeration
recovery system as per DISCHARGING instructions.
5 Remove the burned-out compressor.
6 Correct the system fault which caused the burn-out. Check
the condition of the capacitor(s) and compressor relay.
7 Install a new compressor and liquid line filter dryer.
8 Evacuate and charge the system as per EVACUATING and
CHARGING instructions.

7 ROUTINE MAINTENANCE

DAILY

Inspect the machine for signs of product leaks past seals and
gaskets. If proper assembly does not stop leaks around seal or
gaskets, check for improper lubrication, worn or damaged parts.
Replace parts as needed with original spare parts from the
supplier.

WEEKLY

Clean and sanitize the machine following the procedures
illustrated on the Operator's Manual of the unit. Check for worn
impellers, bowl gaskets, faucet pinch tubes or stainless steel
piston gaskets. Replace parts as needed with original spare
parts from the supplier.
MONTHLY
Clean all internal components, primarily the condenser, using
compressed air, vacuum or a soft brush.
To clean these internal parts, unplug the unit and remove the
panels. Condenser fins are very sharp. Use extreme caution
when cleaning.
On Arctic Deluxe dispensers the condenser is located on the
back of the unit and air flow is from back to sides (A). To clean
the condenser it is necessary to remove the back panel.
On Arctic Compact dispensers the condenser is always
located on the back of the unit but air flow if from sides to back
(B). To clean the condenser it is necessary to remove the faucet
side panel and to clean it from the inside of the unit (see figure
5).
