Installer’s Guide
HORIZONTAL RIGHT
a.
For maximum efficiency
and Customer ease of
filter maintenance, it is recommended that a
properly sized
remote filter
grille be installed
for horizontal applications. Airflow should not ex-
ceed the face velocity of the filter being used.
The factory installed filter should then be
removed from the unit.
b. Unit is shipped from the factory in the upflow or
horizontal right configuration. Unit conversion is
not required.
c. If the unit is suspended, it must be supported
from the bottom near both ends as well as the
middle to prevent sagging. The service access
must remain unobstructed. If the unit is sup-
ported along the length of the front and back, the
air handler only needs to be suspended at both
ends. See Figure 11.
d. If the unit is not suspended it must be supported
as mentioned above and isolated carefully to pre-
vent sound transmission. Vibration isolators (pur-
chased locally) must be placed under the unit.
e. It is always recommended that an auxiliary drain
pan be installed under a horizontal air handler
(See Condensate Drain Piping) to prevent pos-
sible damage to ceilings.
f. Isolate the auxiliary drain pan from the unit or
from the structure.
