ance company, in writing, of any possible
damage.
Environmental protection
Eliminate packing in accordance
with the regulations in force on
environmental conservation.
Contains greenhouse effect fluorided gas
covered by the Kyoto protocol
For the type of gas and quantity per system,
see the identification plate.
GWP (Global Warming Potential): 2088.
Installation of indoor unit
Fasten the mounting plate to the wall.
Tighten screws slightly. Level the mounting
plate, and then tighten screws to a maximum
(Fig. 2).
If the tubing goes through the back of the
unit, drill a 50 mm. diameter hole in the wall.
The outer side of this hole should be slightly
below the inner side (Figs. 3 and 7). Install
the through guide.
The refrigerant lines can be installed in dif-
ferent positions (Fig. 6).
Installation of the interconnecting tubing
and wiring, with the central mounting
plate located at the back of the chassis.
Hang the upper part of the unit over the
mounting panel and press forward. Fasten
the indoor unit to the mounting plate per-
manently.
Bend the tubing carefully, without flattening
or obstructing it.
Pass the tubing and cables of the unit
through the hole; and hand the upper part
of the indoor unit on the upper edge of the
mounting plate (see Fig. 2).
Make sure the unit is installed properly,
moving it first to the left and then to the
right.
