Install Instructions

OPERATION

AND SERVICE

When installation is complete, plug TrueSTEAM in and turn the humidity control on. Make sure it is running

properly before turning the system over to the homeowner. Once TrueSTEAM is running, day-to-day operation is

hands-free, except for occasional cleaning. The homeowner can use the control to adjust the humidity setpoint,

adjust the frost setting (if used), or turn TrueSTEAM off as desired.

Slide the cover into place and secure with the

cover screw.

Turn on the water supply at all valves. Cold water will

ow to the TrueSTEAM but will not ll the tank until the

unit is turned on and a call for humidity is made.

Plug in the TrueSTEAM power cord.

• The Power light will turn on, indicating that

TrueSTEAM has power.

Turn the humidity control to On.

• The Humidifying light will start blinking. This means

TrueSTEAM is in Stand-by.

Press/release the Go button to prepare TrueSTEAM

for use. TrueSTEAM will automatically reset if the Go

button is not pressed after 5 minutes.

• The tank will ll with cold water and the humidier

light will be blinking. Water ow stops automatically

when the tank is full.

• The Humidifying light will be solidly on — it will stop

blinking — when TrueSTEAM is heating water for

steam production.

Wait until TrueSTEAM produces steam, then check

the following:

• Make sure air is blowing from furnace. Typically, the

blower turns on 10 –15 minutes after the call for

humidity if TrueSTEAM is controlling the fan.

• Check all water line connections to ensure there

are no leaks before leaving the job site.

• Turn the setpoint to the desired level when testing

is complete. If humidity is not needed, set the

control to Off.
