Drain Pan Removal (Units with Condensate
Overflow Switch Option)
Before drain pan removal, the switch wire must be
disconnected from wire tie on panel and/or any tape
before drain pan can be removed.
Care must be taken so the wire does not catch on the
bottom of indoor coil or any protrusion.
Note:
When reversing the drain pan, on some units, the
condensate overflow switch will need to be moved
to the second hole in its bracket to avoid contact
with headers or indoor coil.
Filter Installation
The quantity of filters is determined by unit size. Access to
the filters is obtained by removing the filter access panel.
Refer to the unit Service Facts (shipped with each unit) for
filter requirements.
Note:
Do not operate the unit without filters.
Field Installed Power Wiring
An overall dimensional layout for the field installed wiring
entrance into the unit is illustrated in
. To insure that the unit’s supply power wiring is
properly sized and installed, follow the guidelines outlined
below.
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.
Note:
If the unit is not equipped with an optional factory
installed non-fused 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).
