MAINTENANCE
:
Caution: Make certain that the power source is disconnected before attempting to service or disassemble
any component. If the power disconnect is out of the line of sight, lock it in the OPEN position and tag to
prevent the application of power.
Electrical
:
Once a year inspect the control panel wiring to make certain insulation is intact and all connections both
factory and field are tight. Inspect all heater and relay contacts. If the contacts appear badly pitted or
burned, replace the contactor/relay.
Cleaning
:
Clean the unit casing, fan and motor once a year. A dirty motor will tend to run hot and eventually will
be damaged internally. Any rust spots on the casing should be cleaned and repainted. The element
can be cleaned by removing the outer cabinet. Do not use any liquid to clean electric components.
Lubrication
:
All units have fan motors that are permanently lubricated. No oiling is required.
