*Units must be field reconfigured for 11/2 ton (18,000 Btuh) operation. See Before Installation section on page 3 for details. NOTE: Numbers in ( ) indicate quantities when there is more than one fan coil unit in the system.

Ensure unit operation within the application guidelines shown in Table 2. When installing the outdoor unit, for cool- ing operation when the outdoor-air temperature is below

55 F, the following accessories are required:

•low ambient kit

•crankcase heater

•winter start kit

•isolation relay (538B heat pump units only)

This will provide cooling operation down to 40 F ambient temperature. For operation down to –20 F ambient tempera- ture, a field-installed wind baffle will also be required.

To complete installation of the system, the following items must be field-supplied for connection of the indoor and outdoor units:

•refrigerant piping

•condensate drain piping

•thermostat

•wiring

For some applications, a fresh air intake, power vent fan, and/or condensate pump kit may be required. Refer to Tables 3A and 3B for physical data.
