Model XTP humidifier troubleshooting guide

Problem

Possible cause

Action

Humidiﬁ er will
not turn on

Field-wired terminal connections

Check L1, N/L2 and Ground connections.

Check wiring connections and settings on accessory items such as high limit switch and airﬂ ow
proving switch.

Internal connections

Follow the shutdown procedure on Page 50, then make sure electrode and high water probe
connections on top of cylinder are securely connected.

Make sure ribbon cable from membrane switch is securely plugged into control circuit board.

Check that terminals from internal components are securely attached to proper tabs on circuit
boards.

Make sure one of the electrode wires extends through toroid ring on current sensing circuit board.

No power to humidiﬁ er

Check main power supply and switch.

Check for proper voltage across L1 and N/L2 terminals.

Humidiﬁ er not turned on

Make sure front cover is attached to engage safety interlock switch. Press On-off button.

No power to 24V control circuit

Make sure ribbon cable from membrane switch is securely plugged into control circuit board.

Check reset switch on transformer.

Check that the transformer line fuses (2) are in place and conductive.

Steam

light does

not turn on.

Call for humidity not being
received

Check wiring and settings of high RH limit switch and airﬂ ow proving switch.

Water constantly
runs down drain.

Malfunctioning drain valve.

Check valve function using Test Mode.

Debris in drain valve preventing
it from closing

Remove cylinder, and clean debris from drain valve.

O-ring in drain valve not
properly seated in groove

Remove cylinder, and reposition O-ring.

Water ﬂ owing from ﬁ ll cup
overﬂ ow port

Check internal hoses, and remove kinks or blockage.

Water is leaking
from humidiﬁ er.

Loose plumbing connections

Check supply water connection at ﬁ ll valve inlet. Tighten as needed.

Check internal hose clamp connections. Reposition clamps and tighten as needed.

Check steam hose connection on top of cylinder. Tighten clamp as needed.

Humidiﬁ er makes
gurgling sound.

Excess condensate in steam hose

Make sure steam hose has constant downward slope to humidiﬁ er or to tees and traps in low
spots of hose.

Fill valve makes
banging sound.

Water hammer from line
pressure

Make sure water supply line does not contact ductwork.

Install shock arrestor.

Install section of 1/4" braided ﬁ ll line. Conform to governing codes.

Humidiﬁ er will
not ﬁ ll.

Field-installed supply water shut-
off valve not open

Open valve.

Malfunctioning ﬁ ll valve

Check valve function using Test mode.

Humidiﬁ er will
not drain.

Debris in drain valve blocking
outlet port

Remove cylinder and clean debris from drain valve.

Malfunctioning drain valve

Check valve function using Test mode.
