Troubleshooting

Lack of heat

1.Check that the room thermostat is set to the desired temperature.

2.Confirm the units have power and the shut-off valves are open.

3.Ensure there is power to the unit and that the pump is working. If the pump is not working properly it may be stuck. Disconnect power and remove screw in center face of the pump. Using a screwdriver, turn the pump shaft several times to free it from sticking. Replace center-screw and re-connect power. If pump still fails to start, it may require replacement.

4.Confirm that the hot water heater is working and that hot water is entering the Clean Air Furnace.

5.Verify that the airflow in and out of the system matches designed specs. If airflow is low, check for blockage in the filter or some other obstruction.

6.Make sure your water heater is sized large enough for heat load of house and for domestic hot water use.

7.Air may still be in the water lines. If so, re-purge the system according to the start up procedure.

8.Confirm that the inlet and outlet pipe connections are not reversed.

9.Ensure that there are no other restrictions in the water lines, such as faulty valves, or debris.

Pump is noisy

Pumps can become noisy when air remaining in the lines interfere with their operation. If this occurs re-purge the system as indicated in the Start-Up Procedure.

HRV core freezes up

1.Make sure that the supply and exhaust lines are balanced according to the "Balancing Procedure" in this manual.

2.If out of balance, ensure that the balancing dampers have not been moved and that there are no obstructions in the outside hoods.

3.If necessary, install optional defrost kit, according to instructions.
