WARNING: HAZARDOUS VOLTAGE – DISCONNECT POWER BEFORE SERVICING

GENERAL

This accessory electric heater is designed to provide power directly to the unit from the accessory heater’s power supply eliminating the need for additional circuits. The power and control wiring use a single polarized plug to connect the heater and the unit. See the Heater Data table on page 4 for the number of circuits required.

1. Check the unit heater label to confirm that the selected Heater is approved for use with this unit in the installed configuration. For some heaters, a corresponding secondary nameplate label is included. Place the label within the heater data table on the air handler nameplate. This is shown in Figure 7.
2. Check the components received for damage. Report any defects or shortages to the transportation company immediately.
3. Be sure the power supply agrees with the listing shown on heater nameplate.

HEATER TABLES

IMPORTANT: The BAYHTR15** electric heat accessory may include up to a combination of four 60 amp circuit breakers to provide an electrical disconnect for service personnel that is intended to help protect internal electrical components in the event of a short circuit or ground fault. As designed, the circuit breakers supplied in the BAYHTR15** accessory DO NOT provide over current protection of the branch circuit. Therefore, the branch circuit(s) shall be sized and protected according to the unit nameplate.

HEATER STAGING

The TEM/A4AH4 air handler families do not stage air flow in correlation with heater element staging. The minimum heating air flow table is representative for any call for indoor heat.
