General information

Unit installation

R-410A unit operate at higher pressures than standard
R-22 units. Do not use R-22 service equipment or components
of units for R-410A equipment.
Read this instruction manual thoroughly before starting the
installation.
• This unit complies with low-voltage (EEC/73/23) and electro-
magnetic compatibility (EEC/89/336) directives.
• The installation must be carried out by a qualified installer.
• Follow all current national safety code requirements. In particu-
lar ensure that a properly sized and connected ground wire is in
place.
• Check that voltage and frequency of the main power supply are
those required; the available power must be adequate to operate
any other possible appliances connected to the same line.
Also ensure that national safety code requirements have been
followed for the main supply circuit.
• After installation thoroughly test the system operation and explain
all chiller functions to the owner.
• Leave this manual with the owner for consultation during future
periodic maintenance.
• The chiller and its components must be periodically inspected to
check for loose, damaged or broken parts.
If these faults are found and not eliminated, the unit could cause
physical injury and damage to goods and property.
IMPORTANT:
During the unit installation first make the water connections
and then electrical connections. If unit is removed first discon-
nect electrical cables, then water connections.
WARNING:
Disconnect the main power supply switch before servicing the
system or handling any internal parts of the unit.
• The manufacturer declines any liability for damage resulting from
modifications or errors in the electrical or water connections.
• Failure to observe the installation instructions or use of the unit
under conditions other than those indicated in Table VIII "Operating
limits", will immediately void the unit warranty.
• Failure to observe electric safety codes may cause a fire hazard in
case of short circuits.
• Inspect equipment for damage due to improper transportation or
handling: file an immediate claim with the shipping company.
Do not install or use damaged units.
• In case of any malfunctioning turn the unit off, disconnect the
mains power supply and contact a qualified service engineer.
• This unit contains R-410A refrigerant, a substance that does not
deplet the ozone layer.
• All manufacturing and packaging materials used for your
new chiller are compatible with the environment and can be
recycled.
• Dispose of the packaging material in accordance with local requi-
rements.
• This unit contains refrigerant that must be disposed of in a proper
manner. When disposing of the unit after its operational life, remo-
ve it carefully. The unit must then be delivered to an appropriate
disposal center or to the original equipment dealer.
• When lifting the unit, never use hooks inserted into the side han-
dles, always use special equipment (e.g. lifting devices, trolleys,
etc.).
• Carefully recover refrigerant within this unit before final disposal or
when servicing. Never vent refrigerant to atmosphere.
Use approved recovery equipment for R-410A refrigerant.
Do not use equipment for R-22 refrigerant.

Choosing the installation site

Positions to avoid:
• Exposed to direct sun.
• Too close to sources of heat radiation, vapour or flammable gas.
• Particularly dusty areas.
Recommendations:
• Choose a position protected from opposing winds.
• Choose a position sheltered from direct sun.
• Choose an area where air outlet and unit noise will not bother
your neighbours. We advise inserting anti-vibration supports.
• Choose a position that allows for the clearances required.
• Floor structure should be adequately strong to support unit weight
and minimize vibration transmission.
• Consider a position which will not obstruct passageways or doors.
508 mm
Fix the unit with locally purchased bolts countersunk in the base to
prevent overturning in case of strong winds.

• For heat pump models, unit must be adequately raised above the
ground surface.

• To empty the condensate water to a drain while operating in
heating mode, use the drain connection underneath on the left of
the pan and use a vinyl pipe with a 16 mm internal diameter.
This must not be used at temperatures lower than 0°C.
Snow
• If the unit is installed in areas where heavy snowfalls may occur,
it is necessary to raise its level at least 200 mm above the usual
snow level or alternatively to use the outdoor unit bracket kit.
