Installing The Outdoor Unit; Air Duct Installation; Installation Of Pipe And Accessories; Adjusting Air Inlet Direction (From The Rear To The Underside) - Bosch Climate 5000 L Installation Instructions Manual

3.3.2

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. 9).
▶ Remove the cover for the pipe connections ( Fig. 13 and 14).
▶ Establish pipe connections as described in chapter 3.5.1.

Air duct Installation

3.4.1

Installation of pipe 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.
▶ To prevent the air discharged by the air conditioner from being drawn
back in directly: 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 ( Tables 7 and figures 32 to 55).

Table 7 External static pressure
The external static pressure (SP1...4) can be set via the configuration
menu of the wired controller.
▶ 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. 4.

▶ Also insulate the pipes to prevent condensation.
3.4.2

Adjusting air inlet direction (from the rear to the underside)

Carry out modification as shown in Fig. 19:
▶ 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 outside air duct

There is an outside air intake opening on the built-in ducted indoor unit
side which can be used if required ( Fig. 5, [2]).
No more than 5% of the air volumetric flow rate can be introduced via the
outside air intake opening.
3.5

Pipework connection

3.5.1

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. Reusable mechanical connections and flared connections are
not permitted indoors.
▶ Tighten flared connections only once.
▶ After releasing, always fabricate the flared connection again.

120 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
120
unit are intended for imperial sizes.
▶ When using metric copper pipes, replace the flare nuts with nuts of a
suitable diameter ( Tab. 8).
▶ Determine pipe diameter and length ( Page 55).
▶ Cut the pipe to length using a pipe cutter ( Fig. 10).
▶ 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. 8.
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. 8.
▶ Repeat the above steps for the other pipes.
