*Field reconfigured to 18,000 Btuh (11/2 tons). See Before Installation section on page 3 for details.

†The valve connection size is 7/8 inch. The recommended line size is 11/8 inch.

3.Remove inlet grilles from indoor unit by sliding for- ward. Reinstall prior to unit start-up.

IMPORTANT: If necessary, reconfigure the 24,000 Btuh fan coil unit to 18,000 Btuh. Unplug the fan motor at the control box harness and plug into the 619CN018 marked connector.

II. STEP 2 — SELECT LOCATION

Consult local building codes and NEC for special installation requirements. See Fig. 3 and 4 for unit dimensions and required clearances.

There are several ways the unit may be installed to different types of ceiling construction. These instructions do not cover all installation methods. As a typical installation, these instructions focus primarily on mounting the unit to metal in

new construction. Plan the installation carefully before you begin. Listed below are some guidelines that should be fol- lowed when determining location for the unit.

1.Place unit adjacent to an outside wall if fresh air is required, ensuring that location allows for complete air distribution.

2.Locate the thermostat in an area that is not subjected to drafts or direct sunlight through windows. Locate the thermostat on an internal wall whenever possible.

3.Allow sufficient clearance for airflow, wiring, refriger- ant piping, and servicing unit (Fig. 3 and 4).

4.Make sure the unit is easily accessible to electrical power.
