Installing The Outdoor Unit; Pipework Connection; Connecting Refrigerant Lines To The Indoor And Outdoor Unit; Connect Condensate Pipe To The Indoor Unit - Bosch Climate 6000i Installer's Manual

▶ Fasten the mounting plate with a further six screws and wall plugs so
that the the mounting plate lies flat on the wall.
▶ Drill wall outlet for the piping (wall outlet should be behind the indoor
unit as a recommendation  Fig. 5).
The markings [1] serves the positioning of the hole.
▶ Change the position of the condensate pipe if necessary ( Fig. 6).
The pipe fittings on the indoor unit are generally located behind the
indoor unit. We recommend extending the pipes before mounting the
indoor unit.
▶ Establish pipe connections as described in Chapter 3.4.
▶ Bend the piping in the required direction if necessary, and knock out
an opening on the side or underneath on the cover panel ( Fig. 8).
▶ Route the piping through the wall and attach the indoor unit to the
mounting plate ( Fig. 9).
▶ Additional mirror metal sheets are available for CLC8001i... T/S/R,
and must be attached at the designated points ( Fig. 10, [2]).
– Determine the position of the mirror metal sheets.
– Pull off adhesive foil.
– Match mirror metal sheets to the mirrored metal sheets that are
already installed [1].
If it is necessary to take the indoor unit off the mounting plate:
▶ Press against the marks on the bottom of the indoor unit, and pull the
indoor unit towards the front ( Fig. 11, [1]).
These marks are not visible on the coloured product types CLC8001i...
as a mirror metal sheet is attached at this point. The indoor unit can still
be removed from the wall in this manner by pressing at the
corresponding points.

Installing the outdoor unit

▶ Place the box so it is facing upwards.
▶ Cut and remove the packing straps.
▶ Pull the box up and off and remove the packaging.
▶ Prepare and install a floor or wall mounting bracket, depending on the
type of installation.
1) Depending on the position of the pipes, either all 4 or only 3 mirror metal sheets
are required.

Connect condensate pipe to the indoor unit

The condensation catch pan of the indoor unit has two connections. A
condensate hose and bung are mounted on these connections at the
factory and can be replaced ( Fig. 6).
▶ Only route the condensate hose with a slope.

▶ Mount or hang the outdoor unit using the anti-vibration coupling for
the feet which is supplied with the unit or is provided on site.
▶ When installing on the floor or wall mounting bracket, attach the
supplied drainage tray [2] drainage elbow [3] to the drainage
hole [1] ( Fig. 12).
Connect a commercial drain hose [4] if water drops and causes problem.
▶ Remove the cover for the pipe connections ( Fig. 13).
▶ Establish pipe connections as described in Chapter 3.4.
▶ Mount the cover for the pipe connections again.

Pipework connection

3.4.1

Connecting refrigerant lines to the indoor and outdoor unit

CAUTION
Discharge of refrigerant due to leaky connections
Refrigerant may be discharged if pipe connections are incorrectly
installed.
▶ When reusing flared joints, always fabricate the flared part again.
Copper pipes are available in metric and imperial sizes, the flare nut
thread is however the same. The flared fittings on the indoor and outdoor
unit are intended for imperial sizes.
▶ When using metric copper pipes, replace the flare nuts with nuts of a
suitable diameter ( Tab. 6).
▶ Determine pipe diameter and length ( Page 12).
▶ Cut the pipe to length using a pipe cutter ( Fig. 7).
▶ Deburr the inside of the pipe at both ends and tap to remove swarf.
▶ Insert the nut onto the pipe.
▶ Widen the pipe using a flaring tool to the size indicated in the tab. 6.
It must be possible to slide the nut up to the edge but not beyond it.
▶ Connect the pipe and tighten the screw fitting to the torque specified
in the tab. 6.
▶ Repeat the above steps for the second pipe.
NOTICE
Reduced efficiency due to heat transfer between refrigerant pipes
▶ Thermally insulate the refrigerant lines separately.
▶ Fit the insulation on the pipes and secure.
