2. Safety Information
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or property damage. Keep this manual for future reference.
General Safety Guidelines:
- Electrical Safety: Ensure the power supply to the RV's air conditioning unit is disconnected before beginning any installation or maintenance. Work with electricity can be hazardous. If you are not comfortable with electrical work, consult a qualified technician.
- Proper Installation: Install the heat kit strictly according to the manufacturer's instructions. Incorrect installation can lead to malfunction or safety hazards.
- Intended Use: This electric heat kit is designed for supplemental heating and is not intended to replace a primary furnace. Do not use it for purposes other than its intended function.

- Inspection: Periodically inspect the unit and wiring for any signs of damage or wear.
3. Setup and Installation
The Coleman Electric Heat Kit is designed for straightforward installation into compatible Coleman Air conditioning units. While installation can be relatively simple, involving a single screw and a plug, it is crucial to ensure correct wiring, especially with computerized systems. If unsure, professional assistance is recommended.
Installation Steps:
- Disconnect Power: Before starting, ensure all power to the RV and the air conditioning unit is completely disconnected at the source.
- Access AC Unit: Open the cover of your Coleman Air conditioning unit to access the internal components where the heat kit will be installed. Refer to your AC unit's manual for specific access instructions.
- Position Heat Kit: Carefully position the electric heat kit within the designated area of the AC unit. The design typically allows for a "plug and play" fit.
- Secure the Kit: Secure the heat kit using the provided screw(s). Ensure it is firmly in place to prevent movement during operation.
- Connect Wiring: Connect the electrical plug from the heat kit to the corresponding receptacle within the AC unit. Verify that all connections are secure and correctly seated. For units with computerized systems, double-check wiring diagrams or consult the manufacturer if any doubt arises.
- Close AC Unit: Once the heat kit is securely installed and wired, close the AC unit cover, ensuring all latches or screws are fastened.
- Restore Power: Reconnect the power supply to the RV and the air conditioning unit.

4. Operating Instructions
After successful installation, the electric heat kit operates in conjunction with your RV's air conditioning system to provide warmth.
Using the Heat Kit:
- Select Heat Mode: On your RV's thermostat or AC control panel, select the "Heat" or "Electric Heat" mode.
- Set Desired Temperature: Adjust the thermostat to your desired temperature setting. The heat kit will activate to provide supplemental warmth.
- Supplemental Heating: This kit is designed to provide a noticeable increase in air temperature, typically around 5 degrees Fahrenheit above the incoming air. It is effective for removing the chill from the air and for use in moderately cool conditions.
- Not a Primary Furnace: Understand that this electric heat kit is not a replacement for your RV's primary propane furnace. For very cold temperatures or to heat the entire RV significantly, the furnace may still be required.
5. Maintenance
Regular, simple maintenance can help ensure the longevity and efficient operation of your Coleman Electric Heat Kit.
Maintenance Tips:
- Power Disconnection: Always disconnect power to the AC unit before performing any maintenance.
- Visual Inspection: Periodically inspect the heat kit and its wiring for any visible signs of damage, corrosion, or loose connections.
- Cleanliness: Ensure that the air pathways within the AC unit, especially around the heat kit, remain free of dust, debris, and obstructions. A clean system operates more efficiently.
- Professional Check: Consider having your RV's HVAC system, including the heat kit, professionally inspected annually.
6. Troubleshooting
If you encounter issues with your electric heat kit, refer to the following common problems and solutions.
Common Issues:
- No Heat Output:
- Ensure the RV's power supply is active and the AC unit is receiving power.
- Verify that the thermostat is set to "Heat" mode and the desired temperature is above the ambient temperature.
- Check for loose wiring connections within the AC unit.
- Inspect the heating elements for visible damage.
- Blowing Cold Air After Extended Use:
- Some units may have a safety mechanism that temporarily turns off the heating element if it overheats or runs for an extended period. Try turning the unit off for a short duration and then restarting it.
- Ensure adequate airflow. Blocked vents or dirty filters can cause the unit to overheat and cycle off.
- Insufficient Heat:
- Remember this is a supplemental heat source. For significant temperature increases or in very cold weather, the RV's primary furnace may be necessary.
- Ensure all windows and doors are closed to minimize heat loss.
If problems persist after attempting these troubleshooting steps, contact Coleman customer support or a qualified RV technician.
