Aprilaire 550 Humidifier Questions & Answers
Routing waterline to pad
1/4" flexible copper pipe. Tap into your cold water line using the included saddle valve (pierces the pipe), attach the 1/4" flexible copper pipe to the saddle valve on the cold water pipe and the solenoid valve on humidifier unit using the included compression fittings. Tada!
Lime scale build up and slime in bottom of filter tray
If your water is suddenly evaporating into limescale, your local water company may have switched to a different water source, or your water softener device is out of salt. The limescale can be easily cleaned with vinegar and a sponge, but this will keep occuring unless you use water that doesn't contain disolved calcium. Try getting an RO water filter and use that water.
Humidity setting of the 152Z27KGM
You should have a dial setting usually on the return duct box near where your filter goes. It is probably about the size of your thermostat. Set at around 40%
No water to furnace humidifier
It's probably the saddle valve. The self-piercing needle rusts and clogs the water line. Replace the saddle valve with a non self piercing one. Also, check the voltage to the solenoid valve on the humidifier. You should be getting 24 ac volts. If not, replace the transformer. If voltage is present and still no water, then replace the solenoid valve (very expensive).
Water leak
your drain pipe is clogged up, going to drain- Duh
Cycling on and off
I had the same problem with my new furnace. it was a crack in the blower fan housing . that was 12yrs ago. it is starting to act similar now. it just will stay running like it is blowing out gas and then restarts occasionally.
