Inspection and Maintenance of the Humidifier Si71-812
42 Maintenance
2.1.3 Inspection of the Drain Pan
Please check
whether there is
any foreign
objects or
contamination in
drain pan 1. Remove the maintenance cover.
2. Check whether there is any foreign objects or contamination in drain pan. Carefully check
around the drain outlet.
Wipe off inside of drain pan.
3. Please close a maintenance cover.
2.1.4 Inspection of the Solenoid Valve
When the solenoid valve fails, the remote controller does not display any error code.
Usage under that status will lead to insufficient humidification and increased tap water
consumption.
The solenoid valve should be checked at the beginning of heating season.
Check for
shutting and
opening.
Check in a similar
fashion when
checking the float
switch operation. 1. Check that the water supply piping is connected securely.
2. Open the water supply shut-off valve. (No water will be supplied at this time.)
3. Run the HRV unit in heating mode.
(See the operating manual included with the indoor unit for details on how to run the unit in
heating mode.)
The water supply will start and the humidifier will begin operation.
4. After starting heating (humidifying), the sound of the water supply solenoid valve will be
heard every 3 or 4 minutes (a clicking sound), so listening for that clicking sound let the unit
run for 30 minutes to make sure that humidifying operation is normal.
Caution If carpentry work is not completed when a test run is finished, tell the customer not to run the
humidifier for the protection of indoor unit and HRV until it is completed.
If the humidifier is run, paint, particles generated from adhesive and other materials used for
carpentry work may cause HRV to get dirty, causing splash or leakage of water.
