Physical Installation
Installing Humidifier
1. Remove the window panel (panel with the
label) by sliding it up, pulling its bottom away
from the humidifier and then pulling down.
2.
Separate the top half from the pan by sliding
the stainless steel retainer off the lips of the
top half and pan. Swing the pan down to
disengage the metal loops on the opposite
end.
3.
Hang the top half of the unit on the (2) tangs
of the Mounting Plate.
4. The round inlet hole should be to the left or
right, as necessary.
5.
The top half must be positioned so that the
step in the side opening engages the
Mounting Plate tangs which prevents lateral
movement of the unit.
6.
Remove and discard packing around the drum
assembly.
7.
Slide the closed end of the drum assembly onto
the motor shaft and place the other end in the
“U” shaped holder.
8.
Slide the stainless steel retainer over the shaft
notch to hold the drum shaft in place.
NOTE: Do NOT use the drum to turn the motor.
Damage to the motor gears will result.
9. Latch the pan onto both metal loops at the
outlet end of the unit.
10. Swing the pan up to engage the Mounting
Plate tang. The pan will nest into the top.
11. Slide the stainless steel retainer over the lips of
the top half and pan at the water inlet end to
lock the assembly into place.
12. Install the humidistat based on the instructions
located inside the box.
13. Install the saddle valve using the instructions
on the package and turn on the water supply.
14. The water level should be 1 3/8” below the
bottom edge of the 5 1/2” diameter bypass
duct opening. If necessary, adjust the float/rod
assembly to provide the correct water level.
