Step 1 — Complete Pre-Installation Checks

UNPACK UNIT — Store fan coil unit in the original packag- ing until it is moved to the final site for installation. When re- moving unit from carton, lift unit by its 4 corners; DO NOT lift unit by its plastic parts.

INSPECT SHIPMENT — Upon receipt of shipment, check fan coil unit for damage. Forward claim papers directly to the transportation company. Manufacturer is not responsible for damage incurred in transit.

Check all items; if any item is missing, notify your dealer. To prevent loss or damage, leave all parts in original packages until installation.

BEFORE INSTALLATION — Perform the following steps before installing indoor fan coil unit. Place the indoor unit up- side down on the floor, then:

1.Remove side panels by sliding forward, then away from sides of unit (Fig. 2). Reinstall prior to unit start- up.

2.Remove air filters from inlet grilles; then remove and retain screws securing inlet grilles to indoor unit. Rein- stall prior to unit start-up.

NOTE: Dimensions shown in brackets [ ] are in mm.
