When connecting refrigerant tubing
• Keep all tubing runs as short as possible (max. 10m), accordingly to the allowable distances from the outdoor unit (see
manual).
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them; screw by
hand and then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before starting the test run.
• Insulate the tubes with foamed polyethylene (min. thickness 8mm)
When connecting hydraulic tubing
• Keep all tubing runs as short as possible.
• Insulate the tubing.
• Check carefully for leaks before starting the test run.
When servicing
• Turn the power OFF at the main power board before opening the unit to check or repair electrical parts and wiring.
• Clean up the site after the work, remembering to check that no metal scraps or bits of wiring have been left inside the
unit being serviced.
• Ventilate the room during the installation or testing the refrigeration system; make sure that, after the installation, no
gas leaks are present, because this could produce toxic gas and dangerous if in contact with flames or heat-sources.
• We recommend this appliance to be installed properly by qualified installation technicians in accordance with the installation
instructions provided with the unit.
• Do not install this appliance where there are fumes or flammable gases, or in an extremely humid space such as a green
house.
• Do not install the unit where excessively high heat-generating appliances are placed.
• Do not install the unit where it could be wetted by drops of water (i.e. in laundries).
• Do not install the unit in rooms with high humidity and subjected to high steam production (in the bathroom, for example).
• Do not install the unit outside.
• Do not install the unit in rooms exposed to the risk of freezing.
IMPORTANT ! The room in which the product is installed must be equipped with floor drain sump, connected to
sewer system.
AVOID
• Direct sunlight.
• Areas where leakage of flammable gas may be expected.
• Locations where large amounts of oil mist may occur (such as in kitchen or near factory equipment) because oil
contamination can cause operation problems.
• To make holes in areas where electrical wiring or conduits are located.
IMPORTANT !
In the absence of the precautions described above, THE MANUFACTURER shall not be held responsible for
any damage caused.
WARNING
INSTALLATION LOCATION
ELETRICAL REQUIREMENTS
•
Before installation, check that the voltage of the electric supply in your home or office is the same as the voltage shown
on the nameplate.
•
All wiring must conform to the local electrical codes. Consult your dealer or a qualified electrician for details.
•
The unit must be properly grounded with a ground (or earth) wire or through the supply wiring.
•
Wiring must be done by a qualified electrician.
•
Deoxidized annealed copper tube for refrigerant tubing connecting the units of the system, it has to be insulated with
foamed polyethylene (min. thickness 8mm). See paragraph “REFRIGERANT CIRCUIT” for dimensions.
•
Anti-freeze oil for flare connections (about 30g.).
•
Electric wire: use insulated copper wires of size and length as shown at paragraph “ELECTRICAL CONNECTIONS”.
•
Tubes for water.
•
If the water hardness exceeds the value of 20 ° F (1 ° F = 10mg of calcium carbonate per liter of water) the installation
of a polyphosphate treatment system responding to current regulations (DPR 59/09 UNI 8065) is required.
1.
Also check the PH of water that should be at least neutral (values from 6.9 to 7). Values below 6.9 can cause corro-
sion of materials.
2.
It is necessary to wash throughly the system after installation of the appliance and before its use.
