Choose a location in a
conditioned space
Place outside the grow room if possible. The capacity of the
humidifier is reduced by the length of the steam hose or pipe due
to condensation. The maximum recommended length of steam
hose is 6 feet. Use hard pipe insulated with 1" thick insulation
rated for 212°F or higher for lengths greater than 6 feet. If 6-foot
steam hose does not reach from humidifier to dispersion tube,
splice in 1" copper pipe using 3/4" x 1" reducing coupling.
See Installation Manual for more details.
• The steam tubelets must face up
regardless of the airflow direction
in the duct. The plate is labeled
“UP” to indicate proper orientation.
• On horizontal duct runs, install the
dispersion tube low in the duct.
On vertical duct runs, center the
tube on the duct. NOTE: If the dispersion tube is mounted on insulated ductwork,
make sure the insulation is not more than 2" thick at tube location.

Duct location and
absorption distance
Absorption distance is the unobstructed straight line distance
needed for steam to be fully absorbed.
• Determine absorption distance based on the lowest air
velocity that the system will see (refer to table below).
• Locate dispersion tube in a straight section of duct, far
enough upstream of any obstructions or bends in the duct.

Install drain line
• Secure 7/8" drain line with the hose clamp provided. Do not over tighten.
• Make sure drain line has a constant downward slope and is not kinked or blocked.
• If floor drain is not available, use condensate pump to route water to a drain.
NOTE: The humidifier uses cold water to temper drain water to less than 140°F.
Water quality and
canister selection
The Steam Humidifier operates on water with conductivity between
75 and 1,250 EC.
• Connect to water supply. Do not use RO or DI water.
• Use cold water only.

Running and
programming control
The maximum humidity set point is 90% and the control comes
with the default maximum humidity set point preset to 65%. See
step 4 in Program Mode of ADMC manual.
Humidifier control jumper setting:
24VAC EXT.
 Jumper (JP2) on right: 24VAC dry contact when
wiring terminals 7 and 8.
Sequence of
operation
1. Green lights:
a. Solid “on/off” light indicates humidifier is turned on.
b. 1 minute flashing “on/off” light indicates power is
restored to humidifier.
c. Steam light on means steam is being created.
d. Fill light on means water is being added to
humidifier.
e. Drain light on means water is draining from
humidifier.
2. Expected noises from the humidifier:
a. Clicking noise of valve opening to add water.
b. Clicking noise of drain valve opening during the
drain cycle.
c. Clicking noise of the relays opening and closing
during normal operation of the humidifier.
d. Sound of water flowing through the humidifier.
3. Humidistat will call for humidity,
a. Steam light will turn green.
i. Electricity will pass through the water in the
canister unit causing the water to heat to
boiling point, which sends the steam up the
hose.
ii. On startup and steam canister replacement the
water within the canister could take at least 30
minutes to boil and several days to condition
and reach full capacity.
iii. Once the water in the canister is conditioned,
the water will boil almost immediately.
4. Drain valve operation
a. Any time the drain valve is activated, the Drain light
illuminates green.

Guide is to be used as reference only. Installation is to be
in accordance with Installation and Operating Instructions
provided with the dehumidifier.
