Right hand side insulation to stick on the 3-pipe side of the BSB
Insulation to stick on the top plate of the BSB
Insulation to stick on the bottom plate of the BSB

Smaller insulation to stick on the back of the SB
2 x Spacer for distancing SB away from the BSB
2 x Lock washer to secure the spacers
8 x Tie-wrap to make 2 straps for securing the insulations
TOOLS
FOR
PROCESSING
Picture 1
Refer to picture 2 for visualizing how to first unscrew the 2
screws (XX) fixing the SB to the BSB. Lift the SB vertically
upward for about 15 mm (1) until you can unhook it away from
the BSB (2).

Picture 2
Let the SB hang with great
care as indicated in picture 3 .
Better solution of course is in
case cables power supply,
wiring to indoor and outdoor
units, and cool/heat selector
are long enough and you have
the service space, is to put the
SB as indicated in picture 5
on top of the BSB top plate.
Keep the 2 screws for later reinstallation.

Stick the smaller insulation (part J) in the exact position on the
back of the SB as indicated in picture 4 . Be sure not to stick
part J over the ventilation holes.

Refer to
picture 7
for instructions on where to stick the
remaining insulation parts (part B~H).
First stick insulation parts B-C-D+E (on the 2-pipe and 3-pipe
sides of the BSB). These parts are designed to let you easily fit
the remaining top-, bottom- and rear insulations consecutively
(parts F-G-H) on correct positions afterwards.

Firmly fix the 2 supplied spacers (part K) into the holes that
secured the SB to the BSB. Do not forget to put the supplied
lock washers (part L) in between the spacers and the BSB.
Refer to picture 5 .

Picture 5
For comfortably sticking larger parts of insulation on the BSB it is
advised to first partially peel the protective cover off the
adhesive, to position the insulation in the correct place and only
then to peel the complete protective cover off. Refer to
picture 6 .

For securing position of noise insulation
throughout the rest of the installation lifetime,
you need to strap the adhered insulation.
Proceed by connecting 2 times 4 supplied
tie-wraps (part M) (4 tie-wraps = 1 strap) to
each other but keep one end open:
■
put the 2 straps over top of the BSB;
■
both straps must be positioned next to the spacers (outside);
■
close the straps and tear them until they are fixed tight;
■
cut off all 8 superfluous ends.
If the result looks like in
picture 8
, you are successful.

Install the SB back in place by fixing it with 2 recuperated screws
on the spacers through the rear plate of the SB.
