Special Procedures for 208-V Operation

PRE-START-UP

WARNING: Make sure that the power supply to the unit is switched OFF before making any wiring changes. Electrical shock can cause personal injury or death.

1.Disconnect the orange transformer-primary lead from the contactor. See unit wiring label.

2.Remove the wirenut from the terminal on the end of the red transformer-primary lead.

3.Save the wirenut.

4.Connect the red lead to the contactor terminal from which the orange lead was disconnected.

5.Using the wirenut removed from the red lead, insulate the loose terminal on the orange lead.

6.Wrap the wirenut with electrical tape so that the metal terminal cannot be seen.

Indoor blower-motor speeds may need to be changed for 208-v operation. Refer to Indoor Air¯ow and Air¯ow Adjustments section on page 13.

Heat Anticipator Setting

The room thermostat heat anticipator must be adjusted prop- erly to ensure proper heating performance. Set anticipator settings for room thermostat according to separate Accessory Electric Heater Installation Instructions.

Failure to make a proper heat anticipator adjustment will result in improper operation, discomfort to the occupants of the conditioned space, and inefficient energy utilization; how- ever, the required setting may be changed slightly to provide a greater degree of comfort for a particular installation.

E. Accessory Installation

At this time, any required accessories should be installed on the unit. Refer to separate accessory installation instructions.

WARNING: Failure to observe the following warn- ings could result in serious personal injury:

1.Follow recognized safety practices and wear protec- tive goggles when checking or servicing refrigerant system.

2.Do not operate compressor or provide any electric power to unit unless compressor terminal cover is in place and secured.

3.Do not remove compressor terminal cover until all electrical sources have been disconnected.

4.Relieve and reclaim all pressure from both high- and low-pressure sides of the system before touching or disturbing anything inside terminal box if refriger- ant leak is suspected around compressor terminals.

5.Never attempt to repair soldered connection while refrigerant system is under pressure.

6.Do not use torch to remove any component. System contains oil and refrigerant under pressure. To re- move a component, wear protective goggles and pro- ceed as follows:

a.Turn off electrical power to unit.

b.Relieve and reclaim all pressure from system.

c.Cut component connecting tubing with tubing cut- ter and remove component from unit.

d.Carefully unsweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch ¯ame.

For unit compressors equipped with accessory crankcase heat- ers, heaters are energized as long as there is power to the unit. Energize crankcase heater 24 hours prior to unit start- up. To energize heater only, set thermostat at OFF position and turn on unit main power at disconnect switch.
