MAINTENANCE & REPAIR

PRE-SERVICE CHECK LIST

You may avoid the cost and inconvenience of an unnec-
essary product call by first reviewing this check list of the
most frequently encountered situations that are not the
result of defective workmanship or materials.

COMPRESSOR RUNS TOO MUCH

1. A refrigerated cabinet automatically compensates for

product loading by running longer and more often.
Before calling for service, check running time for at
least one hour the first thing in the morning (before
store traffic starts).

2. Be sure the doors seal. A faulty gasket seal will cause

increased running time.

3. Check the room temperature. The warmer the room,

the more the compressor will run.

4. Check the condenser to be sure the face is clean. Dirt

and lint will raise pressures and increase running
time. Use a brush or vacuum to clean the condenser.

5. Be sure condenser fan operates.

6. Check to see that evaporator fans are running.

7. If product is too hard (cold), try setting the

Temperature Control (thermostat) warmer. This will
result in warmer cabinet temperature and reduced
running time.

8. Check insufficient ventilation to condenser.

CABINET DOES NOT OPERATE

1. Be sure cabinet is plugged in.

2. Check that breakers or fuses are good and all switch-

es in the supply line are ON.

3. Be sure that cabinet Master Power Supply Switch is

ON.

4. If you are in an area with voltage problems, try shut-

ting off all non-essential electrical equipment.

LIGHT IS OFF

1. If the cabinet is operating, be sure the lamp is prop-

erly seated in sockets.

2. If cabinet is not running, check that Master Power

Supply Switch and Light Switch are ON, fuses are
okay, no switch in the supply is OFF, and that the cab-
inet is plugged in.

CUSTOMER COMPLAINT ON STORED
PRODUCT

1. Check cleaning solutions used inside cabinet.

2. Check cleaning solutions, paint, or other contami-

nants used in store maintenance.

3. Sometimes the ingredients used in some products or

containers will contaminate other products.

4. Be sure to follow a weekly schedule for cleaning cab-

inet interior.

SERVICE

In the event of a malfunction, damage to the cabinet,
or if the cabinet requires service beyond the items in
the “Pre-Service Checklist,” contact your local service
company or the dealer from whom the cabinet was
purchased.

POWER FAILURE

Do not open the cabinet doors unnecessarily if power is
cut off due to electrical failure. The cabinet will start up if
the power supply returns, but will require sufficient time
to reach maximum cold storage performance.

CABINET FAILURE

1. If the cabinet has stopped operating, check that the

cabinet is securely plugged in and turned on. Contact
a licensed electrician to locate and correct any power
supply problems.

2. Do not open the cabinet doors unnecessarily.

3. Provisions for other storage of the product may be

required to prevent spoilage.

If you call for service, describe your problem and give the
following information to the service representative:
