4. Installation / Setup

Installation of the HKR-05 Auxiliary Heat Strip should only be performed by a qualified HVAC technician. Refer to the specific Goodman air handler or furnace installation manual for detailed wiring diagrams and compatibility information. The following steps are general guidelines.

4.1 Pre-Installation Checks

Verify that the HKR-05 is compatible with your existing HVAC system.
Ensure the electrical supply matches the requirements of the heat strip (5Kw, single phase).
Confirm that the installation location (e.g., air handler cabinet) has adequate space and proper airflow.
Turn off all power to the HVAC system at the main electrical panel before proceeding.

4.2 Installation Steps

Mounting: Securely mount the HKR-05 heat strip within the designated compartment of the air handler or furnace, following the manufacturer's instructions for the specific HVAC unit. Ensure it is positioned for optimal heat distribution and airflow.
Electrical Connections: Connect the pre-wired leads of the heat strip to the corresponding terminals in the HVAC unit's control board or power distribution block. Refer to the wiring diagram provided with your air handler/furnace. Ensure all connections are tight and secure.
Grounding: Ensure the heat strip is properly grounded according to local electrical codes.
Circuit Breaker: Install the appropriate circuit breaker(s) in your electrical panel, sized correctly for a 5Kw electric heater. Note: The HKR-05 does not include a circuit breaker.
Final Checks: Double-check all wiring connections for correctness and security. Ensure no wires are pinched or exposed.

5. Operation

The Goodman HKR-05 Auxiliary Heat Strip operates automatically in conjunction with your HVAC system's thermostat and control board. It is designed to provide supplemental heat when the primary heating source (e.g., heat pump) cannot meet the heating demand, or when the system is set to "Emergency Heat" mode.

5.1 Normal Operation

When the thermostat calls for heat and the outdoor temperature is below the heat pump's efficient operating range, or if the heat pump cannot maintain the set temperature, the auxiliary heat strip will be energized.
The heat strip will cycle on and off as needed to maintain the desired indoor temperature.

5.2 Emergency Heat Mode

If your HVAC system has an "Emergency Heat" setting, selecting this mode on your thermostat will typically disable the heat pump and rely solely on the auxiliary heat strip for heating. This mode is generally used if the heat pump is malfunctioning.

Note: Electric auxiliary heat consumes more electricity than a heat pump. Use it judiciously to manage energy costs.

6. Maintenance

Regular maintenance ensures the longevity and efficient operation of your auxiliary heat strip. It is recommended that a qualified technician perform annual inspections and maintenance.

6.1 Recommended Maintenance Tasks

Power Disconnection: Always disconnect all electrical power to the HVAC system at the main electrical panel before performing any maintenance.
Visual Inspection: Annually inspect the heating elements for any signs of damage, corrosion, or excessive dust accumulation.
Cleaning: Gently clean any dust or debris from the heating elements and surrounding area using a soft brush or vacuum cleaner. Ensure no foreign objects are lodged within the unit.
Electrical Connections: Check all electrical connections for tightness and signs of overheating or corrosion. Tighten any loose connections.
Air Filter: Ensure the air filter in your HVAC system is clean and replaced regularly as per your system's recommendations. A dirty filter can restrict airflow and reduce heating efficiency.

7. Troubleshooting

If you experience issues with your Goodman HKR-05 Auxiliary Heat Strip, refer to the following common troubleshooting steps. For complex issues, contact a qualified HVAC technician.

7.1 Common Issues and Solutions

Problem	Possible Cause	Solution
No heat from auxiliary strip	Power supply off Tripped circuit breaker Faulty thermostat setting Blown fuse or tripped limit switch Wiring issue	Check main electrical panel for power. Reset the circuit breaker. Ensure thermostat is set to "Heat" or "Emergency Heat" and temperature is above ambient. Inspect fuses and limit switches (qualified technician only). Have a qualified technician inspect wiring.
Insufficient heat	Dirty air filter Restricted airflow Undersized unit for space Malfunctioning heating element	Replace or clean air filter. Check for obstructions in ductwork or vents. Consult with an HVAC professional. Have a qualified technician inspect and replace elements if necessary.
Burning smell	Dust accumulation on elements (common for first use after long period) Overheating components	The smell should dissipate quickly. If it persists, turn off power and contact a technician. Immediately turn off power and contact a qualified technician.
