Reversing The Belt Drive Package; Hanging The Unit From A Ceiling - Daikin Destiny VFD Series Installation And Maintenance Manual

Reversing the Belt Drive Package

A motor side or "hand" is determined by looking in the direction
of air flow with the air contacting the back of the head. The drive
package on the air handler can be changed to the other side of
the blower. The motor base and motor are attached to back of
the fan housing. They can be removed, rotated 180 degrees,
and reattached. The fan sheave can be removed and reinstalled
on the opposite end of the shaft
Adjustments on page 47 when reinstalling the belts.
To reverse the drive package:
1. Loosen the belt adjustment screws to relieve the drive
belt tension.
2. Remove the drive belt and the blower pulley.
3. Loosen the two upper bolts on the motor mounting plate
and slide the motor out from the blower housing mount.
4. Move the top motor mounting bolts to the bottom motor
mounting plate location and vice versa. Fasten securely.
5. Turn the motor 180° and slide it back into the blower
housing mount and tighten bolts.
6. Install the blower pulley and the belt to the other side of
the blower housing.
7. Adjust belt tension.
NOTE: Change the motor wiring so the motor rotates in the
opposite direction.

Hanging the Unit from a Ceiling

Do not suspend the unit from the top. The unit top will not support the weight
of the unit. Equipment damage and severe personal injury can result.
Before hanging, rig and completely assemble the unit. The
Destiny air handler has circular knockouts on the corner
connections. Remove the knockouts and suspend the unit
using threaded rods and hardware (by others) with required
C-channels (by others) on both sides as shown in
13. On unit sizes 007 and larger, L-channels (by others) are
required on both ends in addition to C-channels. For 002 -
010 sized ceiling hung units, spring isolation of the cabinet is
recommended.

On unit sizes 007 and above, L-channels (by others)
on both ends are also required.
