Bryant 569C installation instructions Ð7Ð

All units except 208/230-v units are factory wired for the volt- age shown on the nameplate. If the 208/230-v unit is to be connected to a 208-v power supply, the transformer must be rewired by moving the black wire from the 230-v orange wire on the transformer and connecting it to the 200-v red wire from the transformer. The end of the orange wire must then be insulated.

Refer to unit label diagram for additional information. Pig- tails are provided for ®eld wire connections. Use factory- supplied splices or UL (Underwriters' Laboratories) approved copper/aluminum connector.

When installing units, provide a disconnect per NEC.

All ®eld wiring must comply with NEC and local requirements.

Install ®eld wiring as follows:

1.Install conduit through side panel openings.

2.Install power lines to terminal connections as shown in Fig. 6.

Install an accessory thermostat assembly according to instal- lation instructions included with the accessory. Locate ther- mostat assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation instructions.

Route thermostat cable or equivalent single leads of colored wire from subbase terminals to low-voltage connections on unit (shown in Fig. 7) as described in Steps 1 through 4 below.

NOTE: Refer to Table 5 for wire conversion information.

NOTE: For wire runs up to 50 ft (15.2 m), use no. 18 AWG (0.82 mm) insulated wire (35 C minimum). For 50 to 75 ft (15.2 to 22.9 m), use no. 16 AWG (1.30 mm) insulated wire (35 C minimum). For over 75 ft (22.9 m), use no. 14 AWG (2.08 mm) insulated wire (35 C minimum). All wire larger than no. 18 AWG (0.82 mm) cannot be directly connected to the thermostat and will require a junction box and splice at the thermostat.

1.Connect thermostat wires to screw terminals of low volt- age connection board.

2.Pass the control wires through the hole provided in the corner post. See Fig. 8.

3.Feed wire through raceway built into the corner post and into the 24-v thermostat connection board. The 24-v thermostat connection is located on the left side of the low voltage connection compartment. The raceway pro- vides the UL required clearance between the high- and low-voltage wiring.

4.Total combined amperage draw of the ®eld-installed liq- uid line solenoid valve and indoor fan contactor must not exceed 22 va. If the speci®ed va must be exceeded, use a remote relay to switch the load.
