J
SELECTING THE LOCA TION
I) By holding the humidifier against the vertical surface of the
warm
OR
cold air plenum, determine the best location for the
unit. Be sure to allow adequate clearance to attach the water
supply tubing, the drain tubing, and clearance for the
humidifier by-pass tubing.
(If mounting Humidifier on cold
air return, allow 6" above top of unit for mounting of
humidistat)
Securely tape the mounting template provided to
the plenum selected. Make sure template is horizontal and
LEVEL. Allow at least 3 inches clearance from bottom line
on template to any part of furnace jacket or other obstruction.
2)
Center punch 4 side mounting holes on template, and drill with
1/8" or smaller drill bit.
WARNING: MAKE SURE YOU ARE NOT CUTTING OR
DRlLLING INTO ANY AIR CONDITIONING OR
ELECTRICAL ACCESSORIES.
3) Cut the plenum opening, using tin snips, by cutting along the
solid line in the center section of the template, as indicated.
4) Bypass Hole Location. Extend centerline from template on
warm air plenum to cold air plenum or vice versa and mark
appropriately. This mark will be used in Step4 of the next
section. Slight variances from horizontal will not affect
performance of the humidifier.
5) Remove template.
INSTALLING THE HUMIDIFIER
1) Start 4 sheet metal screws in side holes. Hang the humidifier
on the 4 screws and tighten.
USE CARE NOT TO OVER
TIGHTEN SCREWS AND CRACK FRAME.
2) LEVEL the Humidifier, using the built-in bubble level inside
the Distribution Tray. Adjust, level, re-tighten screws, if
necessary.
CAUTION: THE HUMIDlFIER MUST BE
LEVEL FROM SIDE TO SIDE AND FRONT TO BACK
TO INSURE WATER EVENLY FLOWS THROUGH THE
EVAPORATOR PAD
3) Secure top and bottom of humidifier housing by marking and
drilling the 4 holes to the plenum. Attach using sheet metal
screws. Check the level and adjust if necessary.
) Using starting collar provided, as template, scribe a circle on
opposite plenum using centerline marked earlier. Cut the opening
and insert tabbed end of collar through hole. Bend tabs over to
secure mounting collar.
5) Mount a 6" elbow (not provided) to starting collar and
determine length of 6" round pipe (not provided) needed to fit
between elbow and humidifier. Mount pipe to elbow and
humidifier by-pass opening.
NOTE: 6" diameter metal flex
duct can be used in place of the 6" elbow and pipe.
6) Drill two (2) 1/8" holes through pipe and mounting ring on
humidifier and secure with two (2) 1/4" long sheet metal
screws. NOTE: Check damper operation to be sure that
screws do not interfere with rotation.
7) Secure pipe at elbow connection and plenum connection (or
metal flex duct if used instead), with sheet metal screws.
WATER CONNECTION
1)
Supply Tube:
Place looped end of Supply Tube into the hole
in the top of the Distribution Tray and assemble the straight
end to the brass fitting at top of solenoid Valve using copper
ferrule and compression nut, and tighten down.
Note:
Make
sure that the looped end of Supply Tube is directed into the
hole in the cover of the Distribution Tray.
2) Tighten down Distribution Tray cover with plastic
thumbscrew provided.
3)
Saddle Valve:
Select nearest
cold
water pipe. Install self-
piercing saddle valve on cold water pipe following the
instructions provided on Saddle Valve package.
4)
Plastic Water Supply Tubing Connection:
Assemble the
plastic water supply tubing, brass tube insert, plastic ferule
and compression nut as shown. (See diagram below) Then,
insert this assembled end of tubing directly into saddle valve
and tighten down the brass compression nut.
5) Assemble the other end of the plastic water supply tubing
(again as shown above) and insert directly into the brass
fitting at the bottom of the Solenoid Valve. Tighten down
brass compression nut.
6) Turn water on and check for leaks. Stop leaks by further
tightening fittings. Check that all fittings are secured.
DRAIN CONNECTION
1) Connect drain hose to the fitting on bottom of drain pan, with
clamp provided.
2) Run hose to suitable drain such as a floor drain, making sure
that the tubing runs continuously downward with no
restrictions. Be sure drain hose is not kinked at any point as
water could back up and overflow out of the Drain Pan.
