TEMPLATE MUST BE LEVEL
Lennox Healthy Climate® Humidifier – Models
1. Place unit on flat surface and pull front cover up on right side. Lift evaporative media and scale control
insert out at the top
2. The unit is assembled for left side discharge. If right discharge is necessary, remove the right and left
screws from the unit interior side walls and exchange the two sides. Reassemble using existing screws.
3. Using a level, position the template at least
applicable), for clearance of the drain line. Trace around template edges. Remove the template and accurately cut the plenum opening 93/4"Wx121/2H, being careful to avoid injury from sharp edges.
4. Place the unit into the plenum opening so that the locking tabs on the bottom are closed down onto the
lower sheet metal edge. While holding the unit in place, install two screws at the top of the unit interior.
5. Install a 6" collar in a convenient location on the opposite plenum. Slip on a 90° elbow and measure the length of 6" round duct required to make the connection. The 6" duct will fit into the round collar on
the side of the unit. If the system has central air conditioning, add a duct damper. Assemble components using sheet metal screws. Support bypass ducts in excess of 4' to prevent sagging.
6. Replace the evaporative assembly complete with the evaporative media by fitting the drain tube into the round receptacle at the bottom of the unit. Push
the assembly in at the top against the beveled tabs. Replace the front cover.
7A. HUMIDISTAT INSTALLATION INSTRUCTIONS FOR
The humidistat is designed for low voltage service to control humidification equipment. An increase in relative humidity expands the nylon ribbon that opens the control switch to stop operation on the humidifier. A decrease in relative humidity reverses the process and closes the control switch. See front for wiring diagram.
FURNACE BEFORE PROCEEDING
LOCATION
a)Locate on inside wall of living area approximately 5' above floor, or in the furnace return air plenum. Use enclosed adapter plate for return air installation.
b)Do not locate control in the direct path of furnace discharge air or drafts from open doors and windows.
c)Do not install where operation might be affected by lamps, sunlight, fireplace registers, radiators, concealed air ducts and pipes, or next to activities that generate moisture.
d)The basic rules for location of thermostats also apply to humidistats.
GENERAL INSTRUCTIONS
a)DO NOT ATTEMPT TO REPAIR OR RECALIBRATE CONTROL. Controls requiring service should be returned to Lennox Industries.
b)Control must be installed to receive no more than 24 volts!
c)Make sure no bare wires are exposed or insulation damaged. Insulation on wire should extend to head of binding screws.
d)Make sure all splices are mechanically and electrically secure.
e)To remove dirt or other foreign matter from nylon ribbon and control interior, dust lightly with a fine, soft brush.
7B. HUMIDISTAT INSTALLATION INSTRUCTIONS FOR
For detailed humidifier control installation and wiring instructions see form Publication 504879M, included with humidifier.
8. Shut off water supply. Open any faucet to relieve water pressure.
TO INSTALL ON COPPER OR PLASTIC PIPE
a) Place rubber gasket in center of hole in top saddle clamp. Place top and bottom saddle clamp around water pipe. Using bolts, tighten saddle clamps
evenly - clamps should be parallel - Do Not
b)Screw valve body into opening in top saddle clamp and tighten.
c)Tighten gland nut onto valve body.
d)Install 1/4"water supply line from humidifier using compression fittings.
e)You are now ready to pierce the pipe. Turn handle until spindle is firmly seated into valve body. The water pipe is now fully pierced. Turning spindle in shuts valve off.
TO INSTALL ON STEEL OR BRASS PIPE
a)Drill 3/16" diameter hole into pipe where saddle valve will be placed.
b)Place rubber gasket in center of hole in top saddle clamp.
c)Place top saddle clamp assembly over hole so that lance fits into hole.
d)Place top and bottom saddle clamp around water pipe.
e)Screw valve body into opening in top saddle clamp and tighten.
f)Tighten gland nut onto valve body.
g)Install 1/4" water supply line from humidifier using compression fittings.
NOTE: For pipe over 1” O.D., use
9. Tap into a water supply line with the saddle valve furnished. The humidifier will function with cold, hot, softened or unsoftened water. The use of service hot water 140°F Max and constant blower operation will provide maximum evaporative capacities. Note: The saddle valve is designed to be fully opened or closed. Do not use it to regulate water flow.
10. Connect tubing from the saddle valve to the inlet side of the solenoid valve using 1/4” O.D. copper tubing (not furnished). DOUBLE WRENCH TO PREVENT
LEAKING AND VALVE BREAKAGE!
11. Connect 1/2” I.D. plastic hose (not furnished) from unit to floor drain. Be sure drain hose has continuous slope. Use caution if hose clamp is used to not over tighten and crack drain spud. NOTE: Do not sweat or directly attach metal
drain line to fitting. Do not use solvent type adhesive when connecting plastic drain hose, since damage to fitting could result.
12. Turn water on.
13. Open saddle valve completely and turn on furnace.
watertight. Check operation to make sure that all electrical components function properly. Set humidistat to recommended level. (See operating instructions in owners manual)
