Trane Technologies BAYHTRN105A Assembly instructions

SINGLE PACKAGE UNIT INSTRUCTION
These instructions are for the installation of supplementary
heaters in single package units described in the table on page 2.
These instructions do not purport to cover all variations in system
hook-ups nor to provide for every possible contingency to be met
in connection with installation. Should further information be
desired or should particular problems arise which are not cov-
ered sufficiently for the purchaser’s purposes, the matter should
be referred to the manufacturer.
1. Check for any shipping damage, and if any, report it to the
carrier immediately.
2. Check the heater nameplate and compare with the table on
page 2 - make certain that the available power supply com-
plies with the table for the particular heater being used.
INSTALLATION OF HEATERS
1. Remove screws that secure the air conditioner’s or heat pump’s
heater access panel (located alongside control box access panel).
2. Remove and discard the patch plate covering the opening where
the heater will be inserted, save the screws for later use.
IMPORTANT: Look through the opening. Locate a small
hole or bracket, on the bulkhead opposite from opening
that the heater element(s) will be inserted into.
There is a heater element(s) support rod extending out from
heater element frame, this support rod is to be inserted in the
small hole or bracket to support heater elements and prevent
damage to the heater due to airflow surges.
▲ CAUTION:
Note the correct position of the
heater before inserting the heater element(s). The word
“BOTTOM” must be positioned as shown in Figures 1, 2, 3,
and 4.
3. Slide the heater element section of heater assembly into open-
ing. See Figures 1 and 3.
▲ CAUTION:
Do not damage the heater element
by scraping on the opening edges, while inserting.
NOTE: Allow heater control box assembly to lie or stand beside
the front of the unit. See Figure 1.
IMPORTANT: Be sure that the heater element support rod
is securely inserted in small hole or bracket to support
the heater element.

4. Secure the heater assembly to the unit with the screws saved
from step 2.
5. There are three (3) short sheet metal screws inserted in the
panel where the heater control box is to be mounted. Remove
these three screws and discard.
6. Position the heater control box and secure with the three (3)
long screws provided with the heater assembly. See Figures 2
and 4.
NOTE: Some heater accessories do not include the hinged access
door on the heater control box. Those have a cover plate on the
heater control box, secured with screws.
7. Connect the polarized plug from the heater control box to the
polarized plug from the air conditioner or heat pump unit. See
Figures 1, 2, 3, and 4.
LOW VOLTAGE WIRING
All low voltage connections have been made to the heater via the
polarized plugs. The low voltage controls can be connected to the
room thermostat from the air conditioner or heat pump Low Volt-
age Leads. (See field wiring diagrams.) Low voltage is 24 Volts.
HIGH VOLTAGE WIRING
1. Remove the unit’s control box access cover.
2. Place the bushing (provided) in the hole in the control box
through which the field wire is to be routed (See Figure 3).
3. Remove the unit’s power supply knockout.
4. Route the field wire through the unit control box and bushing
into the heater compartment.
5. Connect the power supply to the heater’s wire leads or fuse
block depending on the particular heater being used. (See the
heater wiring diagram for hookup connections.)
6. Connect the power supply ground lead to the heater’s ground
lead or ground lug depending on the particular heater being
used.
7. Close the heater control box cover.
8. Reinstall the control box access panel and the heater access
panel.
9. Restore power to unit.
