Installing The Outdoor Unit; Installing The Air Duct In Built-In Ducted Indoor Units; Installation Of Pipes And Accessories; Adjusting Air Inlet Direction (From The Rear To The Underside) - Bosch Climate 5000 MS Series Installation Instructions Manual

3.3.4

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.
▶ Set up or hang the outdoor unit.
▶ When installing on the floor or wall mounting bracket, attach the
supplied drainage elbow and gasket ( Fig. 7).
▶ Remove the cover for the pipe connections ( Fig. 9).
▶ Establish pipe connections as described in Chapter 3.5.1.

Installing the air duct in built-in ducted indoor units

3.4.1

Installation of pipes and accessories

The appliance must be hung in order to install the pipes, etc.
If an air filter is not used, dust particles may accumulate in the heat
exchanger and cause malfunctions and leaks.
▶ Cut the air filter (not included in scope of delivery) to the size of the
air inlet and attach.
▶ To prevent the air discharged by the air conditioner from being drawn
back in directly, or to prevent a short circuit: plan the air outlet and air
inlet so that they are not too close to one another.
▶ Before installing the air duct, make sure the static pressure of the air
duct is within the permitted range:
Model
Pressure range
CL5000MS 07 DCT
CL5000MS 09 DCT
CL5000MS 12 DCT
CL5000MS 18 DCT
Table 13 External static pressure
▶ Always incorporate isolators when connecting the air conduits to the
appliance in order to prevent the noise from the indoor unit being
transmitted to the ventilation pipes.
▶ Attach the air duct as shown in Fig. 41.

3.4.2 Adjusting air inlet direction
(from the rear to the underside)
Carry out modification as shown in Fig. 42:
▶ Remove filter grille [3].
▶ Remove fan plate [1] and air inlet flange [2].
▶ Bend fan plate on the rear through 90°.
▶ Reinstall the fan plate in the position previously occupied by the air
inlet flange and vice-versa.
▶ Guide the filter grille [3] into the air inlet flange.
3.4.3

Installing the fresh air duct

There is a fresh air intake opening on the built-in ducted indoor unit side
which can be used if required ( Fig. 39).
No more than 15 % of the air volumetric flow rate can be introduced via
the fresh air intake opening.
3.5

Pipework connection

3.5.1 Connecting refrigerant pipes 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. 14).
▶ Determine pipe diameter and length ( Page 30).
▶ Cut the pipe to length using a pipe cutter ( Fig. 8).
▶ 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. 14.
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. 14.
A connection pair (gas side and liquid side) exists for every indoor unit.
Different connection pairs must not be mixed ( Fig. 6).
▶ Repeat the above steps for the other pipes.
NOTICE
Reduced efficiency due to heat transfer between refrigerant pipes
▶ Thermally insulate the refrigerant pipes separately.
▶ Fit the insulation on the pipes and secure.
