TABLE 3 – HUMIDIFIER TROUBLESHOOTING GUIDE
Problem Possible Cause
Water constantly runs down Debris in drain valve
drain . preventing it from closing .
O-ring in drain valve is not
properly seated in groove .
Water is flowing from fill cup
overflow port .
High static pressure in duct
is causing back pressure in
canister .
Humidifier is filling and High static pressure in steam
water is flowing down drain line is causing back pressure
but Drain light is not on . in canister .
Humidifier makes gurgling Excess condensation in steam
sound . hose .
Fill valve makes banging Water hammer from line
sound . pressure .
Humidifier will not fill . Saddle valve not open or
pipe not pierced .
Hoses are blocked .
Humidifier will not drain . Debris in drain valve blocking
outlet port .
Service light flashing red
Canister full of mineral
before end of humidification deposits .
season .
Humidifier runs in short
cycles (does not reach
capacity) .
Yellow Steam light . Humidifier operating below
rated capacity . (Normal
operation for systems
plumbed to low conductivity
water and systems that
operate for short cycles . )
Action
Remove canister and clean debris from drain valve .
Remove canister and check O-ring for damage . Replace O-ring as necessary . Ensure O-ring is
properly seated in its groove .
Check internal hoses and eliminate kinks or blockage .
Make sure dispersion tube is not discharging into duct with greater than 2 . 0 in . w g static
pressure .
Make sure dispersion tube tubelets are pointed up .
Install a tee and drain trap in any low points in the steam line . See FIGURE 6 .
Install Tee and Trap Model 4028 as shown in FIGURE 6 .
Make sure steam hose has constant downward slope to humidifier or to tees and traps in low
spots of hose .
If hard pipe is used for dispersion system, make sure it is insulated .
Make sure water supply line does not contact ductwork .
Install shock arrestor .
Install section of 1/4" braided fill line . Conform to local codes .
If water supply pressure is greater than 120 psi, install pressure reducer .
Make sure saddle valve is properly installed and the valve is open .
Check internal hoses and eliminate kinks or blockage .
Remove canister and clean debris from drain valve .
Remove canister and rinse with clean water .
Plumb humidifier to filtered water .
Plumb humidifier to softened water .
Use blower activation feature on ADHC or run constant fan . Allowing the humidifier to run for
longer cycles to concentrate minerals and increase water conductivity .
Plumb humidifier to softened water .
Use blower activation feature on ADHC or run constant fan .
Operate humidifier on 208/240 volts .
To determine operating current, attach clamp-on ammeter to one of the electrode wires on top
of canister .
Dissolve one teaspoon of salt into one cup of hot water . Add to the fill cup in 1/4 cup increments
until unit operates properly . Yellow Steam light will clear after first fill valve cycle at nominal
amperage operation . Do not over salt . System will drain and refill with clean water due to over
current fault .
