Evacuating The Cooling System Of The S42Xx & S52Xx(B) & Sja2519 Models - Qlima S42 Série Manuel D'installation

d. The cable can be fed through from the back of the interior unit to the terminal strip.
e. Connect the electrical wires to the terminal strip, for the correct location see fig 20.
Figure 20
f. Attach the cable of the indoor unit. Remove the cover plate of the terminal strip of the outdoor unit.
g. Connect the connection cable to the terminal strip (zie picture 21). Attach the cables so that the posi-
tion of the wires matches the connection of the cables to the indoor unit (the letters L N S, the earth
cable and, for the models with a capacity > 6.0 kW, the numbers 1 + 2).
h. The earth cable must be connected directly to the metal plate on which the terminal strip is mounted.
The location is indicated with the symbol
i. In models with a capacity of up to 6.0 kW, the supply cable is already preassembled on the inside
part. In models with a capacity > 6.0 kW, the supply cable must be connected to the outside part (the
supply cable is not included).
j. Only connect the power supply cable once the entire installation of the air conditioner has been
completed.

TAKE CARE
For models with a capacity < 4.5 kW plug the plug into a wall socket.
For models with a capacity > 4.5 kW connect the power supply cable directly the power source.
Do not use a plug and socket as the high current can damage both the terminals of the plug and
the socket and even cause a fire.

12. EVACUATING THE COOLING SYSTEM OF THE S42XX & S52XX(B) & SJA2519
MODELS
Air and moisture that remain in the refrigerant system, e.g. after installation, can cause undesirable effects
or damage as indicated below:
• Pressure in the system rises.
• Operating current rises.
• Cooling or heating efficiency drops.
• Moisture in the refrigerant circuit may freeze and block capillary tubing.
• Water may lead to corrosion of parts in the refrigeration system.
• Damage of the compressor.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must always be leak tested
and evacuated with aid of a vacuum pump to remove any noncondensables and moisture from the system.
