REMKO CMF / CMT
■
The outdoor- and the indoor
modules are connected with
two copper pipes of refrigerator
quality having the dimensions
“ and “ (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.
■
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 suitable
union nuts. (Figs. 6 - 8).
Connection of refrigerant lines
Connection to the unit
■
Remove the cover panel from
the outdoor module. It may be
necessary to remove the pre-
cut bushings.
■
Take off the factory-fitted
protective caps. You can use
the union nuts for additional
mounting. Make sure to slide
the union nuts onto the pipe
before it is flared.
■
Make connections to the device
by hand initially, in order to
ensure a good fit. Later, tighten
the joints with two open-end
wrenches Use one wrench to
resist
the rotation of the other
(Fig. 9).

Special measures need not be
taken for the return of the com-
pressor oil.
8 Correct flange shape
■
The installed refrigerant pipes,
including the flare connections,
must be provided with suitable
insulation.
Use only tools which are
approved for use in an HVAC
environment. (z. B.: bending
pliers, pipe/tubing cutters, de-
burrers and flaring tools). Do
not cut refrigerant pipes with a
saw.
NOTE
Outdoor modules may be
delivered with nuts suitable for
joining flanges.
NOTE
All work must be carried out
in a way that prevents dirt,
particles, water etc. from
entering, refrigerant lines!
