Step 4 — Prepare Unit —
Be sure that unit power re-
quirements match available power source. Refer to unit name-
plate and wiring diagram. Check all tags on unit to determine if
any shipping screws are to be removed. Remove screws as
directed.
Step 5 — Position Unit
1. The air handler has
5
/
8
-in. knockouts in each corner of the
top and bottom panels for suspension rods to pass
through. Be sure to support the unit from underneath until
mounting is complete.
2. Install vibration isolators as shown in Fig. 1. Field-
supplied and field-installed accessories must be indepen-
dently supported or suspended. It is recommended that a
trapeze suspension be used on 42BHE size 30 and 40
units. Size your trapeze to ensure that you do not block
bottom access for filter removal.
3. For units with mixing boxes, follow Step 9 for installation
instructions.
4. To ensure proper drainage and operation, be sure unit is
level. DO NOT mount the unit on a slope. The pitch of a
suspended unit can change after coil is filled; recheck
after filling. Drain pan has built-in slope to ensure proper
drainage.
5. Sufficient clearance must be maintained for service and
maintenance. Ensure that there is a minimum clearance of
24-in. on access side for motor, pulley and belt access.
Filter shall be removed from side or top of the filter rack
on vertical unit (42BVE) and side or bottom of the filter
rack on horizontal unit (42BHE). If side access to filter is
desired, the minimum clearance required is the width of
the filter rack plus 6 inches.
6. Protect unit from damage from jobsite debris. Do not
allow foreign material to fall into drain pan. Prevent dust
and debris from being deposited on motor or fan.
