sensed.
Yes, system will

Overow error code is usually caused by one of two things:
1. Back pressure on the nozzle or remote hose.
2. Back pressure on the drain tube.
Ensure that static duct pressure is not above .5” wc.
If this is a remote install:
1. Make sure the remote hose has a minimum rise of 2” per foot.
Flat, or downhill pitches, even a sharp bend can contribute to
back pressure.
2. Ensure that remote hose rises 6” from the steam humidier
before it angles to the remote mount location.
3. Ensure that the remote nozzle is not pointing in to the airow.
Drain Tube:
1. Ensure that the has s steady downhill pitch with no at or
uphill areas.
2. Ensure drain hose is not kinked or submerged in water at the
drain.
3. Check functionality of condensate pump, if used.
If the above does not resolve the issue:
1. Follow the tank cleaning steps listed in the manual.
2. After cleaning, if the fault returns, unplug steam humidier
3. Loosen cover screw & remove cover.
4. Troubleshoot water sensor.
5. Replace sensor if innite resistance is not shown from P1 &
P3, P1 & P4, P2 & P4 and P4 & P5
6. Press button to Reset unit.
