Filter Installation
Each unit ships with one inch filters.
The quantity of filters is determined
by unit size. Access to the filters is
obtained by removing the indoor fan
access panel. To modify the unit's
filter rack to accept two inch filters,
remove the L-shaped angle
attachment screws and rotate the
angles 90 degrees.
Reinstall the screws and insert new
filters. Refer to the unit Service Facts
(shipped with each unit) for filter
requirements.
Note: Do not operate the unit
without filters.

12. To insure that the
unit's supply power wiring is
properly sized and installed, follow
the following guidelines.
WARNING
Ground Wire!
All field-installed wiring must be
completed by qualified personal. All
field-installed wiring must comply
with NEC and applicable local codes,
failure codes. Failure to follow this
instruction could result in death or
serious injuries.

Verify that the power supply
available is compatible with the unit's
nameplate ratings. The available
supply power must be within 10% of
the rated voltage stamped on the
nameplate. Use only copper
conductors to connect the power
supply to the unit.
CAUTION
Equipment Damage!
Use copper conductors only. Unit
terminals are not designed to accept
other types of conductors. Failure to
use copper conductors may result in
equipment damage.
Note: If the unit is not equipped
with an optional factory
installed nonfused
disconnect switch or circuit
breaker, a field supplied
disconnect switch must be
installed at or near the unit in
accordance with the National
Electrical Code (NEC latest
edition).

Black Gasket around conduit
plate on all 4 sides after
installation to prevent air
leakage from the building
entering the electrical
enclosures.
Note: Seal between wiring and
conduit with Black Gasket or
weather proof sealer to
prevent air leakage from the
building entering the
electrical enclosures. Also
seal around conduit and
wiring at all roof and curb
penetrations.
