BAD INSTALLATION
Supply Duct
Warm Air
Figure 6
1. The humidifier body is not mounted level on the duct. The water which flows to the distribution
tray and through the evaporator pad will all run down one side of the evaporator pad.
2. The bypass collar and tube and humidifier body are not mounted level. This will restrict air
flow through the humidifier as well as create uneven air-flow over the evaporator pad and
activating sensors.
3. The bypass tube used is well over the 36" supplied, the flex tube is not pulled tight and the
most direct route to the opposite duct was not taken. This will restrict air flow through the
humidifier as well as create uneven air-flow over the evaporator pad and activating sensors.
INSTALLATION TIP: In this type of installation the installer should have mounted the bypass collar
and damper in the most convenient location to run ducting back to the unit. If for some reason
it was necessary to run ducting like this, hard metal ducting and elbows (sold separately) rather
than the flex tube should be used; the installer should also try to find the most direct route to
duct. While the humidifier and bypass collar and damper may be more than the recommended
30", apart the use of hard ducting rather than the flex ducting will make up for any restrictions or
turbulence which would occur in aluminum flex tube. Flexible ducting may be the most convenient
for installation purposes however when it comes to air-flow it is highly restrictive (Figure 7), its
use should be kept to a minimum and when used it should be pulled as tight as possible.

PREPARING THE HUMIDIFIER FOR INSTALLATION
Model 5000 humidifiers may be mounted on the supply (hot air) or return duct (cold air),
however we recommend for safety reasons you install it on the return duct, this will minimize
the high temperature the unit and components are exposed to. Only install on the supply duct
(hot air) if absolutely necessary and ensure that the water supply, drain tube, or any other
component do not come into contact with hot surfaces or sharp edges. Replace any component
at the first sign of wear.
CAUTION:
WHEN CUTTING OR DRILLING INTO DUCTING TAKE CARE NOT TO DAMAGE
ANY AIR-CONDITIONING COILS OR OTHER FURNACE APPARATUS.
CAUTION:
WEAR SAFETY GLASSES AND WORK GLOVES WHEN INSTALLING THIS UNIT;
SHARP METAL EDGES CAN CAUSE SEVERE INJURY.

STEP #1: RIGHT HAND DUCTING OR LEFT HAND DUCTING
Depending on your furnace, or for the convenience of your installation it may be necessary to
convert the humidifier from right hand ducting or left handing ducting. Follow the steps below to
switch the side which the bypass duct will attach to the unit. SWITCH THE DUCTING ONLY IF
YOUR APPLICATION REQUIRES IT.
1. Remove the humidifier front cover, which is secured in place with a 10-24 plastic thumb
screw at the bottom of the cover. Tilt the cover away from the body slightly (approx. ½") and
then lift up the cover to free the hooks at the top of the unit.
2. Remove all loose components packaged inside and any packaging. With a firm pull,
disconnect the water tube from the water nozzle and remove the evaporator pad assembly
by sliding it toward the top of the humidifier, then lifting it out (Figure 8).
Figure 8
3. Remove the two #6 screws which hold the humidifier side in place (a short handled screw
driver will give you easier access to the screws) (Figure 9).
Figure 9
4. Lift the humidifier side out of the right hand position, turn the part and position it on the
other side of the humidifier (Figure 10).
Figure 10
5. Use the two screws removed in step 3 to secure the humidifier side in the left hand side.
