Assembly of cover CL5000iL 4C ...

▶ Remove the air inlet grille from the cover ( Fig. 22).
▶ Remove the cover at the 4 corners ( Fig. 23).
NOTICE
Damage to the cover and display
The display is fixed at one of the removable corner covers and can be
damaged when removing the corner.
▶ Carefully lever the corner clamps with a screwdriver and lift off the
corners.
▶ Attach the 4 corner hooks of the cover in the tabs of the indoor unit,
paying attention to the orientation ( Fig. 24). If required, bring the
cover into the correct position by turning it The corner with the
display [2] must be orientated on the electronics [3] and be located
above the refrigerant lines [1].
▶ Evenly tighten the screw hooks until the thickness of the foam
between the casing and the air outlet on the cover is roughly 4-6 mm.
The edge of the cover should be tight against the ceiling.
▶ Remove the foam parts from the inside of the unit.
Only reinstall the air inlet grille when establishing the electrical
connection.

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. 10).
▶ Remove the cover for the pipe connections ( Fig. 14 and 15).
▶ Establish pipe connections as described in chapter 3.5.1.

Installing the outside air duct

There is an outside air intake opening on side the appliance, which can
be used if required ( Fig. 4 and Fig. 5, [3]).
No more than 5% of the air volumetric flow rate can be introduced via the
outside air intake opening.

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.
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. 7).
▶ Determine pipe diameter and length ( Page 50).
▶ Cut the pipe to length using a pipe cutter ( Fig. 11).
▶ 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. 7.
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. 7.
▶ Repeat the above steps for the other pipes.
NOTICE
Reduced efficiency due to heat transfer between refrigerant pipes
▶ Thermally insulate the refrigerant lines separately.
▶ Fit the insulation on the pipes and secure.
