Installer’s Guide
Follow these instructions to install the supplementary
heaters in packaged units as described in the heater
tables throughout this guide
These instructions do not purport to cover all variations
in system hookups nor to provide for every possible
contingency to be met in connection with the
installation Should further information be desired, or
should particular problems arise which are not covered
sufficiently for the purchaser’s purposes, refer the
matter to the manufacturer
1 Check for any shipping damage and report any to
the carrier immediately
2 Check the heater nameplate and compare with the
heater tables to ensure the available power supply
complies with the table for the particular heater
being used
IInnssttaallll HHeeaatteerrss
1 Remove screws that secure the heater panel
(located within control box access panel)
2 Remove and discard the patch plate covering the
opening where the heater will be inserted
3 Slide the heater element section of heater assembly
into the opening and, tipping the heater slightly
forward against the unit barrier, slide the heater up
to engage the lip on the top of the barrier opening
Push forward to engage the slot on the bottom of
the heater face into the tongue on the barrier This
will hold the heater in place Replace the four
screws removed in step 1 See Figure 1, p 6
4 Connect the polarized plug from the heater control
box to the matching polarized plug on the bottom
of the air conditioner or heat pump unit control box
See Figure 1, p 6
LLooww VVoollttaaggee WWiirriinngg
All low voltage connections have been made to the
heater via the polarized plug The low voltage controls
can be connected to the room thermostat from the air
conditioner or heat pump Low Voltage leads See
wiring diagrams Low voltage is 24 Volts
1 Open the heater’s control box access cover
2 Remove the unit’s power supply knockout
3 Route the field wire through the heater
compartment and strain relief bushing into the
bottom of the heater housing
4 Connect the power supply to the heater’s wire leads
or fuse block depending on the particular heater
being used
5 Connect the power supply ground lead to the
heater’s ground lead or ground lug depending on
the particular heater being used
6 Place the included extra heater wiring diagram on
the inner surface of the control/heater access panel
next to the unit wiring diagram, as the diagram on
the heater may be only partially visible when
installed
7 Close the heater housing cover
8 Reinstall the control box/heater access panel
9 Restore power to the unit
The BAYHTRV115, 120, 125, 315, 3230 and 325 electric
heaters have an inner pivoting control box to allow
easy access to fuse links mounted on the heater back
plate Remove the 2 screws from the top front of the
heater control box and pull the top of the inner control
box toward you For easier replacement of contactors,
after pivoting the inner control box toward you,
remove the screws securing the top brace of the h eater
control box as shown in Figure 1, p 6

Field Wiring – Air Conditioners
Notes:
1. Fused disconnect size,
power wiring and grounding
of equipment must comply
with codes..
2. Be sure power supply agrees
with equipment and heater
nameplate.
3. Low voltage wiring to be 18
AWG minimum conductor.
4. See heater nameplate for
current rating of heater
used.
5. See unit and heater
diagram for electrical
connection details.
6. Jumper must be connected
between 1 and 2 for fan to
operate in heating.
7. Some thermostats provide
the ‘G’ signal in the cooling
mode only. To provide the ‘G’
signal in the heating mode
an accessory relay is
required. See fig. 3 for
proper connections.
8. For cooling only omit the
electric heater, associated
power wires and the ‘W’
signal thermostat wire.
9. Fig. 4 demonstrates
connection of the two stage
electric heat thermostat
accessory only. For further
unit connection details refer
to the other figures.
10. The 41A (BR) wire is first
stage electric heat. If the
electric heater accessory has
two heating stages the 41C
(BR) wire is second stage
electric heat.
