INSTALLATION
10.11 WIRING
It MUST MAKE AN EFFECTIVE EARTHING
The manufacturer is not responsible for damage caused in the absence of the same
The electrical connections must be made according to the
following indications:
- Use cables that meet the current standards in different
countries.
- Follow the order of connecting phase, neutral and ground.
- Install a suitable protective device and the electricity
disconnection with delayed characteristic curve, contacts
opening of at least 3 mm and an adequate breaking and
leakage protection.
- If the power of the machine appears to be three-phase, one
must be sure to observe the exact sequence of steps (check
with gauges work properly).
- The supply voltage of the condensing unit must have a value
between ± 10% of the indicated value on the production
data plate. If this is not respected, you have to contact their

10.13 INSTALLATION OF PIPES FOR COOLING
The main cause of refrigerant leaks is due to a defect in flaring. Make folders correctly observing the following guidelines:
Cut the copper cooling pipes and the electrical cable
1. Use tubes with appropriate measures the installed unit.
2. Measure the distance between the Indoor and Outdoor Unit.
3. Cut the pipes to a slightly greater length of the measured
distance.
4. Cut the electrical cord 1.5 m longer than the length
of the tube.
filler positioning
Remove the nuts fixed indoor and outdoor unit, insert them on
the tube, and perform the flanging and the removal of burrs as
previously indicated.
A. Securing the refrigerator connection
1. Align the pipes.
2. sufficiently tighten the nut with the help of two keys

electricity supplier. In the presence of three-phase supply, the
unbalance between the three phases, must be at most 3%.
- It is forbidden to enter the electrical wiring in the condensing
unit in any other part than that provided by the manufacturer
(the holes with rubber grommet).
- Pass compulsorily the power supply cable through one of
the holes with rubber grommet located on the left side of
the car. The electrical connections are made on the terminal
block that is located inside of the electrical components
located behind the inspection panel.
- Connect the cable to terminals inside the electrical panel.
- Avoid direct contact with metal parts.
- Ensure, after about 10 minutes of operation of the
condensing unit, the closure of the screws on the power
terminal.
burr removal
1. Completely remove all burrs from the pipe cross section.
2. The machining should be performed with the machinable
end down so that the burrs do not fall inside the copper tube.
flaring
Secure the copper tube with a die size indicated in the table.
B. Precautions
An excessive torque can ruin the folder and cause refrigerant
leakage.
