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

or wider. When required, attach the adapter
plate to the back of the heater on the side op-
posite the knockouts using 2 screws.
