Installation

Before starting

Creation of refrigerant lines
To create the refrigerant lines you
will need refrigeration quality
annealed copper tubing. These tubes
are available on the local market
together with the insulation and
mounting equipment. These units
must be connected using screw
connections/flare type for unit sizes
512 to 536 and brazed connections
for unit sizes 048-060.
Electrical connections
Use insulated copper wire. The
section of the core varies depending
on the length required. Refer to
table 1 for the recommended
sections. The wiring and electrical
connections must comply with
national electricity regulations.
Check that the electrical
characteristics on the nameplate
correspond to those of the national
grid. The electrical installation shall
include a disconnect switch in
compliance with local electrical
regulations.
WARNING!
Never open the indoor or outdoor
unit without first disconnecting the
power supply. There is a risk of
electrocution.
