5.4.3 Air Handling Unit Mounting
Refer to the installation overview in
Figure 5 on page 14
and required clearances in
"Location and Suggested
Clearances" on page 22
, then mount the humidifier on the air handling unit as follows
:
1. Select a location where the unit is not exposed to severe weather, or where the temperature drops
below -40 °F (-40 °C), and where the wind speed does not exceed 100 mph (160 km/h). External
bracing (supplied by others) will be required when wind speed exceeds 100 mph (160 km/h).
IMPORTANT! The warranty does not cover damage to the humidifier or property caused by
winds in excess of 100 mph (160 km/h).
2. Select a reasonably flat, non-vibrating vertical mounting surface on the air handling unit that is suit-
ably reinforced (strength equivalent to 2×4 stud or 1-5/8 in × 1-5/8 in ×12 gauge Unistrut channel),
and capable of supporting the full operating weight of the humidifier – refer to Table 9 on page 57 for
weights.
3. Mark the attachment points “A” and "B" at the desired position with the help of a level. Refer to
Fig-
ure 10 on page 25 and Table 5 on page 24 .
4. Mark the location of the cutout "C" for the steam line, and cut out a suitable size opening in the air
handling unit. Refer to
"Dimensions" on page 58
for the size of the steam outlet.
5. Secure the mounting bars to the air handling unit with four 1/4-20 UNC bolts (supplied by others).
Make sure that the mounting bars are level, and tighten the bolts.
6. Install suitably sized pipe chases for the drain lines and water supply line – refer to
Figure 9 on page 23
for general locations.
7. Remove the shipping straps, the packaging crate and the foam spacers around the unit. Then remove
the shipping screws that secure the unit to the shipping skid, and carefully slide the unit to the rear
of the skid so that the unit is flush with the edge of the skid.
8. Install the shipping screws and secure the unit to the shipping skid again.
WARNING!
Heavy object – risk of personal injury and damage to equipment!
Prevention: While the unit is still attached to the shipping skid, raise the humidifier using a
forklift or crane. Protect the unit from damage by tethers and other lifting equipment, and do not
drop the humidifier.
9. Carefully raise the humidifier into position and align the mounting brackets on the back of the humidi-
fier with the installed mounting bars, as shown. Lower the humidifier onto the mounting bars, and
make sure that the unit is seated properly and level.
10. Secure the humidifier to the mounting surface at attachment point(s) "B" with 1/4-20 UNC bolt(s)
(supplied by others). Tighten the bolt(s).
11. Seal the opening in the air handling unit around the steam line.
12. Remove the shipping screws and the shipping skid from the bottom of the unit.
