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 sev- eral 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 Air Handler.

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 domes- tic 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 connec- tions 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.

During cooling cycle, hot water cir- culates through the coil

If the check valve inside the cabinet is stuck in the open position, hot water may infiltrate the heating coil. This occurs when the hot pipes are not capped-off during installation or service and for- eign debris enters the piping. This debris can set- tle under the check valve seat and permit hot water to flow into the coil. The problem can be cor- rected by repeatedly flushing the heating loop until it is clean.
