Maintenance
For more effective and safer operation and to prolong the life of the heater,
read the Owner's Guide and follow the maintenance instructions included with
each heater. Failure to properly maintain the heater will void any warranty and
may cause the heater to function improperly. Warranties are non transferable
and apply to original consumer only. Warranty terms are set out below.

Plus (CS), Com-Pak Twin Plus (CST), series element or motor found to be
defective within two years after the date of purchase.
These warranties do not apply:
1. Damage occurs to the product through improper installation or incorrect
supply voltage;
2. Damage occurs to the product through improper maintenance, misuse,
abuse, accident, or alteration;
3. The product is serviced by anyone other than Cadet;
4. If the date of manufacture of the product cannot be determined;

Solution
1. Verify that supply voltage matches the heater rating.
2. 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.
3. Shorted supply or heater 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.
4. Replace the circuit breaker.
1. Allow a few moments for element to reach operating temperature.
2. Verify that supply voltage matches the heater rating.
3. Replace element.
4. CST models have two heating units with independent over-temperature
controls. One of the high-temperature manual power reset controls may trip
and cut power to one of the heating units, while the other remains running,
resulting in only half output. Reset the heater unit (see "Operation &
Maintenance" section for "Resetting the Manual Power Reset Limit Control").
1. Close doors and windows. Provide additional insulation, or install a higher
wattage heater or multiple heaters if necessary. (If your circuit is rated for
more capacity.)
2. Adjust thermostat to its lowest setting. If heater continues to run (allow two
minutes for the thermostat to respond), and room temperature is greater than
50˚; replace the thermostat.
3. Refer to thermostat documentation and correct wiring.
1. Clean heater (see "Operation & Maintenance" section for instructions).
1. Heater or fan motor requires replacement.
2. Remove obstruction and follow instructions in the "Operation & Maintenance"
section for "Resetting the Manual Power Reset Limit Control." Test heater
operation. If heater does not run, heater requires repair or replacement.
1. Adjust thermostat to a higher temperature until heater operates (see Problem #6
if the problem persists).
2. Follow instructions in the "Operation & Maintenance" section for "Resetting
the Manual Power Reset Limit Control." If room temperature is below 45˚, see
"Reset Heater at the Circuit Breaker" instructions.
3. A severe over-temperature condition has occurred. Repair or replace heater.
4. Turn on the correct circuit breaker in the main panel.
5. Turn off power at circuit breaker. Check supply wire continuity and proper
connection to heater wires.
6. The entire heater, or any of its components may be checked for continuity
to determine the cause of any problems. Repair or replace the heater.
