Check line connections to make sure they are tight, free of oxide build-up, and that no dust or dirt build-up is
present. Retighten to 20 in-lbs as necessary.
Check enclosure (inside) for rust, dirt or dust. Remove rust if present, with steel wool (or equal) and thoroughly
blow clean with dry, oil-free air.
If enclosure is moisture resistant, check condition of cover gasket. A replacement can be obtained from the
factory.
Liquid immersed units should be removed from tank and checked periodically for scale build-up. Clean as
required. Scale can cause high sheath temperature and result in inefficiency and shortened life.
Thermal cycling may cause sealed joints to relax causing a leak. Tightening of heater plug should stop leak.
Replacement Parts
Reference the Screw Plug heater part number on the nameplate when ordering replacement parts.
Recommended spare parts would be : a Screw Plug Heater and thermostat (if supplied).
Contact your local Watlow distributor for ordering replacement parts. Check the Yellow Pages under "Electrical
