Step 1 — Complete Pre-Installation Checks
UNPACK UNIT — Store fan coil unit in the original pack-
aging 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.
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 Car-
rier distributor. 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
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 re-
tain screws securing inlet grilles to indoor unit. Reinstall
prior to unit start-up.
NOTE: Dimensions shown in brackets [
] are in mm.
