I. STEP 1 — COMPLETE PRE-INSTALLATION CHECKS

A. Unpack Unit

Store fan coil unit in the original packaging until it is moved to the final site for installation. When removing unit from carton, lift unit by its 4 corners; DO NOT lift unit by its plastic parts.

B. Inspect Shipment

Upon receipt of shipment, check fan coil unit for damage. Forward claim papers directly to the transportation com- pany. 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.

C. Before Installation

Perform the following steps before installing indoor fan coil unit. Place the indoor unit upside 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. Reinstall prior to unit start-up.
