During cooling cycle, hot water circulates 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 foreign debris enters the piping. This debris can settle under the check valve seat and permit hot water to flow into the coil. The problem can be corrected by repeatedly flushing the heating loop until it is clean.

Water sits in drain pipes

1.Check drain pans or lines for plugs.

2.Confirm that the HRV core is installed according to manufactures recommendations.

3.Check the drain line for kinks.

4.Make sure that the O-ring in the drain nozzles sit flat.

5.Ensure the drain line has enough "fall" to it.

Condensation/ice forming inside ventilation ducts

A rip in the vapor barrier or poorly sealed joints may cause condensation or ice to form on the ducting. If this occurs, replace the entire line.

Humidity levels are too low

1.If you have installed a dehumidistat ensure that its setting is correct. (Summer - OFF) (Winter - 30% RH to 45% RH).

2.Check humidifier settings. (Summer - OFF) (Winter - 30% RH to 45% RH). NOTE: Humidifier should always be 10% lower than dehumidistat.

3.Change thermostat fan switch from manual to automatic.

Humidity levels are too high

1.If you have installed a dehumidistat ensure its setting is correct. (Summer - OFF) (Winter - 30% RH to 45% RH).

2.Install a dehumidistat if necessary. (Winter use only. Not for hot southern climates).

3.Change thermostat fan switch from automatic to manual.

NOTE: The CAF has the ability to dehumidify during the heating season. (When outside air is less humid than indoor air). If you are in a region where outdoor humidity levels are typically higher than indoor humidity levels, a dehumidistat should not be used in this system.
