Do not use joints or extensions for the pipes that connect
the indoor and outdoor unit. The only permitted connections are those for which the units
are designed.
Connect the indoor and outdoor units using pipes
with flared connections(not supplied). For the lines,
use insulated, unwelded, degreased and deoxidized
copper pipe,(Cu DHP type to ISO1337), suitable for
operating pressures of at least 4200kPa and for a
burst pressure of at least 20700kPa. Copper pipe for
hydro-sanitary ap- plications is completely unsuitable.
For sizing and limits (height difference, line length,
max. bends, refrigerant charge, etc.) see the outdoor unit installation manual.
All refrigerant connection must be accessible, in
order to permit either unit maintenance or removing it completely.
10
Use the bender which have a minimum bending radius when you
bend the pipe.
Be careful so that the pipes is
bended one time only. Piping will
be very difficult if you repeat the
bending more than twice.
If you bend the pipe by using
spring Bending radius should be
more than 100mm so that pipe is
not distorted.
