______

After applying power to the heater make sure that the system is being controlled properly before leaving it to run unattended. Failure to do this could result in overheating resulting in personnel danger and fire.

Troubleshooting

PROBLEM

No power available to heater

Fuses blowing

Not enough power

Air not heating to desired temperature

High limit tripping / alarm

Cause / Correction

Check disconnect switch to ensure it is in the "ON" position and that fuses are not blown. Replace fuses if they are blown

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.

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

Not enough Kw or incorrect voltage being applied

Too much heat loss, higher wattage heater may be required

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. Re tighten 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.

Replacement Parts

Reference the duct heater part number on the nameplate when ordering replacement parts. Recommended spare parts would be : a Modular Duct Heater, replacement module, and high limit thermocouple or high limit thermocouple kit.

To replace individual heater module:

a)Disconnect power and then feeder wire

b)Remove terminal hardware connecting module to be replaced and other adjacent modules.

c)Remove the two Allen head screws and split washers holding module to main flange.

d)Pull module through main flange as shown below.
