Maintaining Your Heater; Troubleshooting Chart - Cadet CE163T Owner's Manual

Maintenance As Needed, or every six months minimum.
WARNING! Before removing grill, turn the electrical power off at the main disconnect panel (circuit
breaker or fuse box). Lock or tag the main disconnect panel door to prevent someone from accidentally
turning the power on while you are working on the heater. Failure to do so could result in serious electrical
shock, burns, or possible death.
WARNING: Any other service not detailed in this Owner's Guide should be performed by an authorized service repre-
sentative.
1. It is important that you verify power has been turned off and
the heating element is cool before proceeding. Circuit breakers
are often not marked correctly and turning the wrong breaker off
could mean electricity is flowing to the heater, even if the heater
does not appear to be working. If you are uncomfortable working
with electrical appliances, unable to follow these guidelines, or do
not have the necessary equipment, consult a qualified electrician.
2. Once you verify the power has been turned off correctly,
proceed to the next step.
3. Remove screws and take off grill.

ELECTRICAL SERVICE PERSONNEL.
1. Close doors and windows. Provide additional insulation, or install a higher wattage
heater or multiple heaters if necessary. (If your circuit breaker is rated for more
capacity.)
2. Remove furniture or other surfaces to appropriate clearances, so air can flow freely
throughout room. Maintain a minimum distance of ¾ inches (1.9 cm) from adjacent
surfaces, 4½ inches (11.4 cm) from the floor, and 3 feet (0.9 m) from furniture or other
objects placed directly in front of the heater.
3. See "MAX/MIN TEMPERATURE LOCK" on page 6.
1. The total amperage of all heaters on a branch circuit must not be more than 80% of
the amperage rating of the circuit breaker and supply wire ratings.
Use a lower wattage heater, or reduce the number of heaters on the circuit.
2. Broken or poorly connected wires may be accompanied by severe sparking.
Inspect all supply and heater wiring insulation for damage. Do not reset the circuit
breaker until all electrical shorts have been repaired.
3. Replace the circuit breaker.
4. Replace heater assembly.
1. Push mode button to HEAT mode (display shows room temperature).
2. Replace element.
1. If room temperature is being regulated and maintained, a low fan speed and low
heat output is normal for this energy saving heater.
2. Close doors and windows. Provide additional insulation, or install a higher wattage
heater or multiple heaters if necessary. (If your circuit breaker is rated for more
capacity.)
3. Replace heater assembly.
1. Clean heater (See "MAINTAINING YOUR HEATER" section for instructions).
2.Turn off power at circuit breaker. Inspect all supply and heater wires for loose or
poor connections. Secure or reconnect all loose connections. Do not reset circuit
breaker until all connections have been checked or repaired.
1. Heater or fan motor requires replacement.
2. Remove obstruction and confirm that fan is spinning freely. Press manual reset
temperature limit button per the "OPERATING INSTRUCTIONS" section.
1. Adjust thermostat to a higher temperature until heater operates (See Problem #6 if
the problem persists).
2. Push mode button to "HEAT" mode.
3. Press the manual reset button (See "OPERATING INSTRUCTIONS" section).
4. Turn on the correct circuit breaker in the main disconnect panel.
5. Turn off power at circuit breaker. Check supply wire continuity and proper
connection to heater wires.
6. Repair or replace the heater assembly.
7. Correct the circuit breaker installation.
1. Clean heater (See "MAINTAINING YOUR HEATER" section for instructions).
2. Remove obstruction. Maintain a minimum distance of ¾ inches (1.9 cm) from
adjacent surfaces, 4½ inches (11.4 cm) from the floor, and 3 feet (0.9 m) from furni-
ture or other objects placed directly in front of the heater.
3. Remove obstruction, and press heater manual reset button (See "OPERATING
INSTRUCTIONS" section).
4. Replace heater assembly.
4. Wash grill with hot soapy water and dry.
5. While holding fan (to avoid damage or bending), use a hair dryer
or vacuum on blow cycle to blow debris through the top element
(do not touch element).
6. Vacuum fan area without touching the elements.
7. Do not lubricate motor.
8. Replace grill and secure with screws.
9. Turn power back on at the main disconnect panel.
