The DVS Air Handler can be installed in a closet on a
supporting stand or be mounted from the closet wall
using the closet as the return air plenum. Unit should be
high enough from the floor to provide unimpeded return
airflow into the bottom of the cabinet.
Closet return air opening can be on the front (in closet
door), side (thru the wall) or a combination of both,
providing there is clearance on the sides between unit’s
cabinet and closet. Refer to ACCA Manual D or SMACNA
for sizing and free area recommendations.
NOTE:
Local codes may limit application of systems without a
ducted return to single story dwellings.

If the cabinet cannot be supported on a frame or supported
from the wall, it may be suspended.
Use metal strapping or threaded rod with angle iron
supports under cabinet for support. These supports
MUST run parallel with the length of the cabinet
(see Figures 6 and 7).
Ensure that there is adequate room to remove service
and access panels after installing supporting brackets.
If an auxiliary drain pan is required, the support is
to be placed under a drain pan. In such installations,
the unit will need to be supported on vibration isolators
(rubber or Styrofoam blocks).
IMPORTANT:
When a DVS unit is matched with an evaporative
type (cased coil/condensing unit) split system for cooling
application and the system is installed above a finished
ceiling and/or an occupied space, building codes may call
for a secondary insulated condensate pan (by others)
to be installed under the entire unit. In other instances,
some local codes may allow the running of a separate,
secondary condensate line in lieu of the required drain pan.
It is the responsibility of the installer to consult local codes
for compliance.
