TSX -20°C Flammable Materials Storage Laboratory Freezers
The condenser is located in the top rear of the machine compartment. To clean
the condenser, complete the following steps:
1. Disconnect the power.
2. Remove the filter.
3. Vacuum the condenser and clean up any loose dust.
4. Replace the filter.
5. Reconnect power.
You should defrost the freezer whenever there is significant frost buildup inside
the cabinet.
Ice buildup in the freezer and around the control sensor could cause drift in unit
operating temperature.
To defrost:
1. Remove all products and place in another cold storage medium.
2. Turn off the unit and allow the interior to warm to room temperature.
Leave the door ajar to shorten defrost time.
3. Dispose of the ice and wipe out any water standing in the bottom of the
cabinet.
WARNING: DO NOT use heating devices such as heat guns and hair
dryers to speed up the defrosting process. Fire or explosion of residual vapors
may result!
CAUTION: When defrosting your freezer, never use sharp or heavy tools
such as chisels or scrapers. Damage to the equipment can result. Let the ice
melt enough so that it can be easily removed.
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 solution.
