8 Connecting the
refrigeration system
8.1 Connection of refrigerant lines
n The outdoor- and the indoor units are con-
nected with two copper pipes of refrigerator
quality having the dimensions 3/8" = 9,52 mm
and 5/8" = 15,88 mm (REMKO special acces-
sory).
n 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.
n The copper pipes are to be flared to make the
connections to the units. In doing so, check
that the flare has the correct shape and suit-
able union nuts. (Fig. 40 to Fig. 42).
