LIMITED TWO-YEAR WARRANTY: Cadet Manufacturing Co. will repair or replace, any Cadet Com-Pak Plus (C), and/or Com-Pak Twin Plus (CT)

element or motor found to be defective or malfunctioning from first date of purchase through the second year.

These warranties do not apply:

1. To conditions resulting from (a) improper installation, or (b) incorrect supply voltage.

2. To conditions resulting from improper maintenance, misuse, abuse, accident or alteration.

3. To service calls or labor involved in replacing defective part.

4. If the date of manufacture cannot be determined.

Cadet shall not be liable for commercial consequential damages such as property damage and incidental expenses resulting from breach of

these written warranties or any implied warranty. These warranties give you specific legal rights, and you may also have other rights which vary

from state to state. Cadet neither assumes, nor authorizes anyone to assume for it, any other obligation or liability in connection with these

electric heaters or any part of such heaters. If the product warranted should become defective during the warranty period, contact Cadet

Manufacturing Co. for instructions on how to have the repair or replacement processed. Products returned without authorization will be

refused. To prolong the life of your heater, it is necessary to follow the maintenance guidelines included with each heater. Failure to maintain

your heater will result in the warranty being voided.

Symptom Problem Solution

Breaker trips immediately upon

energizing heater.

Heater fan operates, but does

not discharge warm air.

Heater will not shut off.

Heater discharges smoke or

emits a burnt odor.

Element heats for a moment

without the fan turning, then

immediately stops heating.

Heater does not run.

Troubleshooting Chart

1.Incorrect supply voltage.

2.Overloaded circuit.

3.A short circuit exists in the

supply or heater wiring.

4.Defective circuit breaker.

1.Insufficient element temperature.

2.Incorrect supply voltage.

3.Element has failed.

4.(Model CT only) One of the

heater units must be reset.

1.Heat loss from room is greater

than heater capacity.

2.Defective thermostat.

3.Thermostat wired incorrectly to

heater.

1.Dust, lint or other matter has

accumulated inside heater.

1.Defective motor or internal

connection.

2.Fan or motor jammed.

1.Thermostat set too low.

2.Heater has tripped the high-

temperature reset switch.

3.Heater has tripped the secondary

over-temperature switch.

4.Power not on at the circuit

breaker.

5.Broken or poorly connected

wire(s) to heater.

6.Defective thermostat.

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. CT models have two heating units with independent over-

temperature controls. One of the high-temperature reset switches

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

that is not operating (see "Operation & Maintenance" section for

instructions).

1. Close doors and windows. Provide additional insulation, or install a

higher-wattage heater or multiple heaters if necessary.

2. Adjust thermostat to its lowest setting. If heater continues to run

(allow a few moments for the thermostat to respond to the

adjustment), replace 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 press heater reset button (after allowing the

unit to cool). Test heater operation--if reset button has been pressed

(be sure to listen and feel for a click indicating it has been reset), but

heater does not run, heater requires replacement.

1. Adjust thermostat to a higher temperature until heater operates (see

Problem #6 if the problem persists).

2. Press the heater reset button (see "Operation & Maintenance"

section for 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. Turn off power at circuit breaker. Jumper across thermostat

terminals. Turn on main circuit breaker. If heater operates,

thermostat is defective and should be replaced. Remove jumper

before operating heater.
