Cadet CM208 Multi-Watt Fan-Forced Wall Heater User Guide
IMPORTANT INSTRUCTIONS
- To avoid burns, do not let bare skin touch hot surfaces the front of the heater and keep them away from the sides.
- Do not operate any heater after it malfunctions.
- Do not use outdoors.
- To disconnect heater, turn control(s) to off, and turn of power to heater circuit at main disconnect panel.
- Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage the heater.
- To prevent a possible fire, do not block air intakes or exhaust in any manner.
- A heater has hot and arcing or sparking parts inside. Do not use it in areas where gasoline, paint, or flammable vapors or liquids are used or stored.
INSTALLATION INSTRUCTIONS
- All electrical work and materials must comply with the National Electric Code (NEC), the Occupational Safety and Health Act (OSHA), and all state and local codes.
- Use copper conductors only.
- DO NOT install the heater directly above bathtub or sink. DO NOT install in shower stall area.
- To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.
- Connect grounding lead to grounding screw provided. Keep all foreign objects out of heater.
TOOLS REQUIRED
PARTS OF YOUR HEATER
TIPS BEFORE YOU BEGIN
- The Com-Pak Max can only be mounted with the element up or to the left. It cannot be mounted in the ceiling or in the floor. For multiple heater wiring, see page 6.
- For cleaner performance and longer heater life, install your heater 12 inches (30.5 cm) from the floor.
- All models can be installed to be Americans with Disabilities Act (ADA) compliant. Check your state and local requirements.
- The wall can label arrows show the correct mounting orientation (arrows must point up).
STEP 1: Cut a hole in the wall next to a wall stud
If you haven’t installed drywall yet, skip this step.
STEP 2: Locate or route electrical supply wires
Route the electrical supply wire from the circuit breaker to the heater location. Remove a knockout from the wall can (best location is closest to heater wires) and attach the supply wire with a cable clamp connector (not included) leaving a minimum of 6 inches (15.2 cm) wire lead (See Figure 3).
STEP 3: Mount the wall can
If you haven’t installed drywall yet, make sure the front of the wall can extends beyond the front edge of the wall stud to match the drywall depth (See Figure 3). If you already have drywall installed, place the can into the cutout so the front is flush with the drywall. Fasten the wall can to the stud with two screws through holes provided in the wall can (See Figure 3).
MULTIPLE HEATERS ON ONE CIRCUIT BREAKER
- Route the electrical supply wire from the circuit breaker to heater #1. Remove two knockouts and attach two sets of electrical supply wire with two cable clamp connectors (not included) leaving a minimum of 6 inches wire lead—one set from the circuit breaker, the other set to heater #2 (See Figure 7).
- The two supply ground wires in the wall can of heater #1 need to make a 3-wire connection with the grounding screw. Attach a short copper ground wire to the grounding screw in the wall can. Connect this wire and the two supply ground wires with a wire connector (not included) (See Figure 7).
- For heater #1, connect each heater wire with one of the supply wires going to the circuit breaker, and one of the supply wires going to heater #2. Each of the wires from heater #1 must have a 3-wire connection. For heater #2, make the connections in the wall can as shown below.
OPERATING INSTRUCTIONS
- Do not operate without grill.
- Do not tamper with the high temperature safety shutoff.
How to operate your heater
Installation is complete and power is on, follow the steps below for your thermostat. If you have a wall or built-in thermostat with a knob:
- Turn the thermostat knob all the way to the right.
- The heater will automatically keep the room temperature around this setting.
- To reduce the room temperature, turn the knob to the left. To increase the room temperature, turn the knob to the right. If you have an electronic wall thermostat, follow the instructions in the programming and operating guide included with your thermostat.
MAINTAINING YOUR HEATER
- Turn off power at the main disconnect panel.
- Wait for the heater to cool.
- Remove knobs and grill.
- Wash grill with hot soapy water and dry.
- Blow air through the heating element with a hair dryer or shop vacuum on blow cycle.
- Clean the fan with a vacuum cleaner.
- Replace grill and knobs.
- Turn power back on at the main disconnect panel.
High-temperature safety shutoff
All Com-Pak Max heaters come with a built-in high-temperature safety shutoff that stops electricity flowing to the heater if it gets too hot inside. See TROUBLESHOOTING below if you’re experiencing problems with your heater.
TROUBLESHOOTING
Symptom Problem Solution | ||
Heater smells after installation or not being used. | 1. Odor from element manufacturing process. 2. Dust or lint inside the heater. 3. Supply connections are loose. | 1. It typically goes away within several hours. 2. Clean heater (see “MAINTAINING YOUR HEATER” above for instructions). 3. Turn off power at main disconnect panel. Inspect and/or tighten all the wire connectors inside the heater and at any connection points. |
Heater doesn’t work at all. | 1. Thermostat is set too low. 2. Heater has tripped its built-in high-temperature safety shutoff and electric- ity has stopped flowing to the heater. 3. Grill pressed against reset button, tripping high temperature safety shutoff. 4. Circuit breaker is faulty. 5. Supply connections are loose. 6. Defective thermostat. | 2. TO RESET: Turn power off at main disconnect panel. Allow 10 minutes to cool. Make sure heater is not blocked and is clean. Push reset button. Restore power.
4. Call a licensed electrician. 5. Turn off power at main disconnect panel. Inspect and/or tighten all the wire connectors inside the heater and at any connection points. 6. Replace the heater. |
Breaker trips immediately after installing heater. | 1. A short circuit exists in the electrical supply wires or heater wiring. 2. Circuit is overloaded. 3. Circuit breaker is faulty. | 1. An incorrect connection in the heater or electrical supply wires may cause sparking or arcing. Inspect all heater and electrical supply wiring insulation for damage or call an electrician. 2. Use a lower wattage heater, or reduce the number of heaters on the circuit. 3. Call a licensed electrician. |
Heater blows cold air or doesn’t get hot. | 1. Element has failed. 2. Incorrect supply voltage. | 1. Replace heater. 2. Double check the voltage of the heater to make sure it matches the voltage of the circuit. |
Heater doesn’t turn off. | 1. Incorrect heater wattage for room size. 2. Defective thermostat.
3. Thermostat wired incorrectly to heater. | 1. Install additional heaters if circuit allows. 2. Adjust thermostat to its lowest setting. 3. Refer to thermostat installation guide and correct wiring. |
Built-in high- temperature safety shutoff keeps tripping. | 1. Airflow is blocked. 2. Dust, lint or other matter has accumulated inside heater. 3. Fan or motor is jammed. | 1. Remove obstruction(s). Maintain minimum distances (See Page 2). 2. Clean heater (see “Maintenance” section for instructions).
3. Remove obstruction, and press heater manual reset button (see “Operating” section for instructions). |
