Technical Service at 1-800-438-4851 for additional
information.
CAUTION!
Maintenance should only be performed
by trained personnel.
8.1 Condenser Maintenance
8.1.1 Cleaning the Condenser
Clean the condenser at least every six months; more often if the
laboratory area is extremely dust prone.
To clean the condenser, complete the following steps:
1. Pull the grill open.
2. Remove the filter. Check the fans. If a fan is not operating,
contact a Revco Authorized Service Company immediately.
3. Vacuum the condenser.
4. Replace the filter and close the grill.
8.1.2 Cleaning the Condenser Filter
Clean the condenser filter every two or three months.
1. Pull the grill open.
2. Remove the filter.
3. Shake the filter to remove loose dust, rinse the filter in clean
water, shake the excess water from the filter, and replace the
filter.
4. Close the grill.
8.2 Gasket Maintenance
Periodically check the gaskets around the door or lid for
punctures or tears. Leaks are indicated by a streak of frost which
forms at the point of gasket failure. Make sure that the cabinet is
level (refer to Section 5.3 on page 2 for leveling information).
Keep the lid and door gaskets clean and frost free by wiping
gently with a soft cloth.
8.3 Defrost Procedures
To defrost the equipment, complete the following steps:
1. Remove all products and place in another cabinet.
2. Turn off the unit and allow the interior to warm to room
temperature.
3. Dispose of the ice and wipe out any water standing in the
bottom of the cabinet.
If there is freezer odor, wash the interior with a solution of
baking soda and warm water. Clean the exterior with any
common household cleaning wax.
8.4 Alarm Battery Maintenance
Have a technician check the condition of the alarm battery at
least once a year.
To replace the alarm battery, complete the following steps:
1. Pull open the front grill. The alarm battery is located directly
behind the grill. The terminals are the “push on” type.
2. Grasp the terminal with pliers and work it gently back and
forth while pulling it off. The fittings are tight.
3. Remove the battery and put the new battery in place.
Note:
You may have to cut a strip of silicone rubber in order to
remove the battery.
4. Connect the battery terminals and replace the front grill.
