TROUBLE SHOOTING GUIDE

PROBLEM: NOT ENOUGH HUMIDITY

POSSIBLE CAUSE: Humidistat set too low.

REMEDY: Turn up the humidistat.

POSSIBLE CAUSE: Humidifier has only been installed for a few

days.

REMEDY: If you have just installed the humidifier it can

take anywhere from 3 to 4 weeks to build up the humidity

level in the home.

POSSIBLE CAUSE: Not enough air flow through the humidifier.

For the maximum performance of 12 us gallons in 24 hrs of

operation there must be at least 0.5” static pressure.

REMEDY:

• Adjust bypass damper to fully open position.

• Ensure the bypass tube is fully stretched out tight.

• Furnace filter is dirty and needs replacement.

• Bypass tube and humidifier not installed parallel, use hard

ducting – use hard ducting for any elbows – take the most

direct route when ducting.

• The bypass tube or humidifier is installed in front of air-

conditioning coils or is blocked in some other way – move to

another location and ensure maximum air flow.

• The humidifier and bypass tube are installed on the

same duct – you must install the unit on either the

supply or return and the bypass tube on the opposite

duct or the unit will not work.

• For some reason your furnace is not supplying sufficient

air to the unit.

POSSIBLE CAUSE: Not enough water is getting to the evaporator

pad. For the maximum performance of 12 US gallons in 24 hours

of operation there must be at least 60 PSI of water pressure.

REMEDY:

• Check that the unit is turned on and plugged in.

• Check that the humidistat is turned up and is calling for

humidity. If at the start of the furnace cycle the humidistat is

not calling for humidity then the humidifier will wait until the

next furnace cycle, even if during the furnace cycle the

humidity level drops below the set point.

• Check that the saddle valve is open.

• Check that the unit is level and that the evaporator pad

assembly is getting evenly wet.

• Check that there is water getting to the humidifier, turn off the

water disconnect the water supply to the unit and turn the

water back on. Allow the water to flow into a bucket,

reconnect the water after test.

• Check the amount of water being supplied to the evaporator

pad. (Procedure in Maintenance Guide)

• Check that the water inlet filter is not plugged. Replace if

required. (Procedure in Maintenance Guide)

• Check that the black orifice fitting is not plugged. (Procedure in

Maintenance Guide)

• The homes water pressure is too low. For rated output the

water pressure must be at least 60 PSI.

POSSIBLE CAUSE: Unit is not cycling with the furnace in heating

mode. For this unit to work it must sense a 4°C temperature rise

over 1 minute of time and the air temperature must be at least

30°C. This ensures that the humidifier is using water efficiently. If

your furnace does not supply the require temperatures you will

have to purchase and install a pressure switch.

REMEDY:

• Check that the unit is turned on and plugged in.

• Check that the humidistat is turned up and is calling for

humidity. If at the start of the furnace cycle the humidistat is

not calling for humidity then the humidifier will wait until the

next furnace cycle, even if during the furnace cycle the

humidity level drops below the setpoint.

• Check that the bypass damper is open and hot air is flowing

through the humidifier.

• Ensure the bypass tube is fully stretched out tight.

• Furnace filter is dirty and needs replacement.

• Bypass tube and humidifier not installed parallel, use hard

ducting – use hard ducting for any elbows – take the most

direct route when ducting.

• The bypass tube or humidifier is installed in front of air-

conditioning coils or is blocked in some other way – move to

another location and ensure maximum air flow.

• The humidifier and bypass tube are installed on the same duct

– you must install the unit on either the supply or return and

the bypass tube on the opposite duct or the unit will not work.

• For some reason your furnace is not supplying sufficient heat to

activate the unit. If you use a heat pump or a high efficient

furnace you may see this problem, or if your furnace is not

working properly. It will be necessary to purchase a pressure

switch to activate the unit (available through our parts and

service line 1-800-465-7300), or you may have the unit hard

wired to your furnace by a HVAC or electrical professional and

bypass the unit's control.

POSSIBLE CAUSE: The air going through the unit is not hot

enough. For the maximum performance of 18 US gallons in 24

hours of operation the air temperature going through the filter

should be 120°F. 100°F=15 US gal/24 hours, 80°F=9 US gal/24

hours, etc.

REMEDY:

• Adjust bypass damper to fully open position.

• Ensure the bypass tube is fully stretched out tight.
