Installation and Operation Manual
Note Unauthorized repair of your freezer will invalidate your warranty.
Contact Unity Lab Service at 1-800-438-4851 for additional information.
CAUTION: Maintenance should only be performed by trained personnel.
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. Check the fans. If a fan is not operating, contact an Authorized Service
Company immediately.
3. Vacuum the condenser.
4. Close the grill.
Periodically check the gaskets around the 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.
Keep the lid gaskets clean and frost free by wiping gently with a soft cloth.
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.
