• This unit complies with the low-voltage (EEC/73/23) and

electromagnetic compatibility (EEC/ 89/336) directives.

• Installation must be carried out by qualified personnel.

• Follow all current national safety code requirements.

In particular ensure that a properly sized and connected ground
wire is in place.

• Check that the voltage and frequency of the mains power supply

are as required for the unit to be installed; the available power
source must be adequate to operate all other appliances

requirements have been followed for the main supply circuit.

• Connection of the system to the mains power supply is to be

carried out in compliance with the wiring diagram shown in
the installation instructions of the external section.

• Connect indoor and outdoor units with field-supplied copper pipes

by means of flare connections. Use insulated seamless
refrigeration grade pipe only, (Cu DHP type according to ISO1337),
degreased and deoxidized, suitable for operating pressures of at
least 4200 kPa and for burst pressure of at least 20700 kPa.
Under no circumstances must sanitary type copper pipe be used.

• Where necessary, use field-supplied 25 mm I.D. PVC pipe (not

supplied) of appropriate length and with the correct thermal
insulation for the condensate drain extension.

• After installation thoroughly test system operation and explain all

system functions to the owner.

• Use this unit only for factory approved applications: the unit

cannot be used in laundry or steam pressing premises.

IMPORTANT:
During installation, make first the refrigerant connections and
then the electrical connections.
If the unit is uninstalled, first disconnect the electrical cables,
and then the refrigerant connections.

Disconnect the mains power supply switch before servicing the
system or handling any internal parts of the unit.
