Filter Installation; Field Installed Power Wiring - Trane Precedent YZC036E Installation, Operation And Maintenance Manual

Installation
2. Remove the support panel that the condensate drain
pan exits through.
3. Slide the condensate drain pan out of the unit.
4. Place on a level surface in the position it was removed
from the unit.
5. Remove the plug knockout in the bottom of the drain
pan to convert it to through-the-base drainage.
6. Plug the original condensate drain opening with a field
supplied 3/4-inch NPT plug.
7. Slide the condensate drain pan back into the unit, align
the drain support with the grommeted opening in the
rear support panel and push until the support is seated
in the grommet.
8. Replace the front support panel by aligning the panel
with tabs in the raceway. Align the plugged
condensate drain pan coupling in the grommeted hole
as the panel is put in place.
9. Replace evaporator access panel and supply air access
panels.
A condensate trap must be installed at the unit due to the
drain connection being on the "negative pressure" side of
the fan. Install the P-Trap using the guidelines in
p. 34.
A condensate drain line must be connected to the P-Trap.
Pitch the drain lines at least 1/2-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".

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

WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. 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.
An overall dimensional layout for the field installed wiring
entrance into the unit is illustrated in the Dimensions and
Weights chapter. To insure that the unit's supply power
wiring is properly sized and installed, follow the following
guidelines.
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.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as unit terminals are not designed
to accept other types of conductors.
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).
