4. Reinstall the heat section access panel.
Condensate Drain Configuration
An evaporator condensate drain connection is provided
on each unit. Refer to
for the
appropriate drain location.
Note:
Use 1" PVC pipe to connect to the drain pan outlet
provided in the unit. This is a slip fit joint (no
threads) and can be sealed using PVC Cement or
other suitable adhesive.
A condensate trap must be installed at the unit due to the
drain connection being on the “negative pressure” side of
the fan.
A condensate drain line must be connected to the P-Trap.
Pitch the drain lines at least ½-inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
allow the horizontal run to sag causing a possible double-
trap condition which could result in condensate backup
due to “air lock”.
Filter Installation
Each unit ships with 2-inch filters installed. 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 standard 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.
Note:
All field installed wiring must conform to NEC
guidelines as well as state and Local codes.
Verify that the power supply available is compatible with
the unit’s nameplate ratings. The available supply power
must be within 10 percent 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 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).
Main Unit Power
Standard Wiring
The electrical service must be protected from over current
and short circuit conditions in accordance with NEC
requirements.
Protection devices must be sized according to the
electrical data on the nameplate.
•
If the unit is not equipped with an optional factory
installed nonfused disconnect switch, a field supplied
disconnect switch must be installed at or near the unit
in accordance with the National Electrical Code (NEC
latest edition).
•
Location of the applicable electrical service entrance is
illustrated in
. Complete the
unit’s power wiring connections onto either; the main
terminal block HTB1 inside the unit control panel, the
factory mounted nonfused disconnect switch (UCD), or
the electric heat terminal block. Refer to the customer
connection diagram that shipped with the unit for
specific termination points.
•
Provide proper grounding for the unit in accordance
with local and national codes.

NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of
conductors. Failure to use copper conductors could
result in equipment damage.
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
