repair.
Maintenance
Daily Maintenance :
Turn power switch off and disconnect main power cord before attempting any maintenance.
Once the water bath has cooled to room temperature you may empty the water.
Wipe off any excess dirt on the interior and exterior with a damp cloth. Do not use benzene,
thinner or cleanser.
Weekly Maintenance :
The pipe heater should be cleaned at least twice a month. Accumulation of scale build up
results in poor heat transfer and high sheath temperatures.
When the unit is not in use for a long period of time.
Be sure to disconnect main power and drain the water tank if the unit will not be used for a long
time.
