SETTING AND WORK
SAFETY AND POLLUTION
GENERAL CONSIDERATIONS
The machine has been designed to reduce risks to persons and to the environment in which it is installed, to the
minimum . To eliminate residual hazards, it is therefore recommended to become as familiar as possible with the
machine in order to avoid accidents that could cause personal injuries and/or damage to the machine .
1 . Pollution:
The machine contains lubricating oil and R32 refrigerant . If the unit is scrapped, these fluids must be recovered and
disposed of in compliance with the laws in force in the country where the machine is installed . The machine must not
be dumped when no longer required for service .
Consult the technical safety briefs available from refrigerant manufacturers for further information about the
characteristics of the cooling fluid .
The Refrigerant
To realize the function of the air conditioner unit, a special refrigerant circulates in the system . The used refrigerant
is the fluoride R32,which is specially cleaned. The refrigerant is flammable and inodorous. Furthermore, it can
leads to explosion under certain condition. But the flammability of the refrigerant is very low. It can be ignited only
by fire. Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The
influence upon the greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a
really high energy efficiency. The units therefore need a less filling.
STARTING UP FOR THE FIRST TIME
Before starting the unit for the first time, before starting the system for seasonal work or after a long period at a
standstill, carry out the following preliminary inspections with regard to the electrical and cooling parts .
PRELIMINARY CHECKS ON THE ELECTRICAL PART
Note:
Before inspecting any electrical part, disconnect the power supply from the machine by unplugging it from the
mains socket .
Checks
• Make sure that the electrical system has been wired-up according to the indications in the wiring diagram and that
the cross section of the cables is adequate .
• Make sure that the power supply and earth cables are firmly connected to the terminals .
• Make sure that there are no disconnected or unhooked cables .
• Make sure that the mains power supply suits the machine requirements .
PRELIMINARY CHECKS ON THE COOLING PART
• Make sure that the unit is loaded with refrigerant . This may be checked by using portable Freon gauges provided
with swivelling SAE ¼" connections with air pump connected to the service connection of the tap . The pressure read
must correspond to the saturation pressure corresponding to the room temperature (~7 bar) .
• Visually check the cooling circuit to make sure that it is not damaged .
• Make sure that the pipes are not dirty with oil (oil stains could denote possible damage to the cooling circuit) .
STARTING
After performing preliminary controls, start the machine with the remote control . Press the ON button and select the
required operating mode .
The remote control functions are illustrated in the user manual .
