ES Series Lab Freezer

Maintenance and Service
All laboratory freezers are manual defrost units.
Before manually defrosting the cabinet, make sure the power lead is disconnected from the mains. Any loose frost found
on the evaporator can be removed carefully using a wooden or plastic scrapper.
WARNING:
DO NOT use heating devices
such as heat guns and hair driers 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.
