ALVE KIT INSTALLATION
Mechanical installation
1
Remove the valve kit box cover by unscrewing 4x M5.
2
Drill 4 holes on correct position (measurements as indicated in
figure below) and fix the valve kit box securely with 4 screws
through the provided holes Ø9 mm.
Brazing work
For details, see manual of the outdoor unit.
3
Prepare the inlet/outlet field piping just in front of the connection
(do
not
braze yet).
4
Remove the pipe fixing clamp (C) by unscrewing 2x M5.
5
Remove the upper and lower pipe insulations.
6
Braze the field piping.
7
After brazing, put the lower pipe insulation back in place and
close it with the upper insulation cover (after pealing off the
liner).
8
Secure the pipe fixing clamp (C) in place again (2x M5).
9
Make sure that field pipes are fully insulated.
Field pipe insulation must reach up to the insulation you have put
back in place as per procedure step 7. Make sure that there is
no gap between both ends in order to avoid condensation
dripping (finish the connection with tape eventually).
Electrical work
1
Open the electrical box cover (A).
2
Push out
ONLY
the second lower wire intake hole (B) from
inside to outside. Do not damage the membrane.
3
Pass valve cable (with wires Y1 ... Y6) from the control box
through that membrane wire intake hole and connect the cable
wires into the terminal connector (C) following instructions as
described in step 4. Route the cable out of the valve kit box
according to figure below and fix with the tie wrap (D). See
"Electric wiring work" on page 92 for more details.
4
Use a small screwdriver and follow indicated instructions for
connecting cable wires into the terminal connector according to
the wiring diagram.
5
Make sure that field wiring and insulation is not squeezed when
closing the valve kit box cover.
6
Close the valve kit box cover (4x M5).
NOTE
Make sure that the expansion valve is installed
vertically.
Make sure there is enough free space for future
maintenance.

box, tie wraps and wires are protected from direct
brazing flames during brazing.
