plug. If leak persists, remove heating unit and add teflon tape or sealing compound to threads and re-install. Care should be taken to observe the orientation of the flange or plug to its original position.

Troubleshooting

PROBLEM	Cause / Correction
No power available to heater	Check disconnect switch to ensure it is in the "ON" position
	and that fuses are not blown. Replace fuses if they are blown
Fuses blowing	Check heater electrical rating. Applied voltage may be wrong
	Check fuse rating. Fuses should be at least 25% more than full
	load amperage.
	Disconnect heater power source. Check the heater resistance
	to ground. This should be no less than 1 Megohm. Refer to
	Megohm checking.
Not enough power	Check line voltage to ensure it is within specification
	Check full line current if voltage is correct. If line current is lower,
	the heater may be wired wrong or has open elements
Fluid not heating to desired	Not enough Kw
temperature	Too much heat loss
High limit tripping / alarm	Not enough fluid flow
	Too much Kw
	Line voltage higher than designed / allowable

Preventative Maintenance

CAUTION: HAZARD OF ELECTRIC SHOCK. TURN ALL POWER TO HEATER OFF, USE

! APPROPRIATE DISCONNECT LOCKOUTS AND ALLOW SYSTEM/HEATER TO COOL BEFORE

PERFORMING ANY MAINTENANCE

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. When the heater is removed or tightened, take care to orient the heater in the position it was originally oriented.

Replacement Parts

Reference the Circulation heater part number on the nameplate when ordering replacement parts. Recommended spare parts would be : an immersion heater, flange gasket, and thermostat (if supplied).
