LOW VOLTAGE CONTROL CONNECTION

The 24 volt power supply is provided by an internally wired low voltage transformer which is standard on all models. However, if the unit is con- nected to a 208 volt power supply the low voltage transformer must be rewired to the 208 volt tap. See the unit wiring label.

Field supplied low voltage wiring can exit the unit on the top right hand corner or the right hand side panel (see Fig. 5, item K).

Install a 7/8" plastic bushing in the selected hole and keep low voltage wiring as short as possible inside the control box.

The field wiring is to be connected at the screw terminals of the control board. Refer to Figure’s 12 and 13.

NOTE: All wiring must comply with local and national electrical code requirements. Read and heed all unit caution labels.

NOTE: It is possible to vary the amount of electric heat turned on during the defrost cycle of a heat pump. Standard wiring will only bring on 5 KW of electric heat during defrost see Table 6 and Figures 12 and 13 for alternate staging.

LINE POWER CONNECTIONS

Power may be brought into the unit through the supply air end of the unit (top when unit is vertical) or the left side panel. Use the hole appro- priate to the unit's orientation in each installation to bring conduit from the disconnect. The power lead conduit should be terminated at the electrical control box. Refer to Tables 4, 8 & 10 for wire requirements. Also see Figure 10.

BLOWER SPEED CONNECTIONS

Except for F4FP045, which has a 4-speed motor, and F5FP* which has a 5-speed high efficiency X-13 motor, all air handlers contain three speed blower motors which are pre-wired to the control board.

Adjust blower motor speed to provide airflow within the minimum and maximum limits approved for evaporator coil, electric heat and outdoor unit. Speed tap adjustments are made at the motor terminal block, See Figure 11. Airflow data is shown in Tables 6 and 11.

Higher efficiencies will be obtained if the indoor air volume is as high as possible provided the CFM does not exceed limitations and the sound level is not objectionable.

Connect motor wires to motor speed tap receptacle for speed desired. See wiring label for motor wiring details. See Figure 11.

The unit control is designed for the addition of a two speed fan kit. See accessory kit for details.
