WARNING:
A. GENERAL
This accessory electric heater is designed to provide
power directly to the air handler from the accessory
heaters power supply eliminating the need for ad-
ditional circuits. The power and control wiring use
a single polorized plug to connect the heater and the
air handler. Single source power entry is provided for
single phase heaters with two circuits using acces-
sory BAYSPEK140B. See the Heater Data table on
page 2 for the number of circuits required.
1. Check the air handler heater label to comfirm that
the selected Heater is approved for use with this
air handler, in the installed configuration.
2. Check the components received for damage. Re-
port any defects or shortages to the transportation
company immediately.
3. Be sure the power supply agrees with the listing
shown on heater nameplate.
B. INSTALLATION

of the air handler.

4. Remove the cover from the heater field wiring
and control compartment box. For heaters up
to 15 Kw, an adapter plate is provided which
is used with air handlers that are 21.5" wide
or wider. When required, attach the adapter
plate to the back of the heater on the side op-
posite the knockouts using 2 screws.
5. Remove the appropriate knockouts in the heater
field wiring compartment. See Figure 1 on page
3. Remove the appropriate knockouts in the air
handler for making electrical connections to the
heater. The holes in the air handler must align
with the holes in the heater field wiring compart-
ment.
6. Insert the heater assembly into the heater cavity
of the air handler so that the field wiring holes in
the air handler and the heater will align. Secure
the heater compartment to the air handler with
the four screws removed from the hardware en-
velope.

the heater control box.
NOTE: Air handlers approved to use the 1425 heater

of the heater cavity. This plate is removed ONLY
when the 1425 heater is used. Otherwise it must
be left in place for a blower barrier seal.

tions must conform to national, state and local
