The outdoor- and the indoor modules are con-
nected with two copper pipes of refrigerator
quality having the dimensions ¼" and ⅝"
(REMKO special accessory).

Observe the permitted bending radius for the
refrigerant pipes during installation in order to
prevent kinks. Never bend a pipe twice in the
same place in order to prevent embrittlement
or crack formation.
n
Assure suitable fastening and insulation when
laying the refrigerant pipes.

The copper pipes are to be flared to make the
connections to the modules. In doing so, check
that the flare has the correct shape and suit-
able union nuts. (Fig. 34 to Fig. 36).
