Installation diagram and technical spaces
The installation should be performed by qualified service personnel and experienced,
reliably and in compliance with this manual.
Contact your service centre prior to installation to prevent malfunction due to a
unprofessional installation.
In taking and moving the units it is necessary to be guided by qualified and experienced
people.
Make sure there is plenty space around the unit.
Collocation
Install junction and drain hose (only for models
with heat pump)
When the unit is in heating mode it produces
condensation, which flows from the outdoor unit.
In order not to disturb neighbors and to respect
the environment, install a fitting and a drain hose
that can steer the condensation water. Install the
discharge fitting and the rubber gasket on the
frame of the outdoor unit and connect a drain
hose as shown in figure.
Keep sealed all open extremities of the
pipes with a cap until the connection is
completed. Be sure not to let anything in
the pipes or in the system, such as dirt,
water, etc.
The piping connected to the indoor and
outdoor unit must be new. Required
thickness of pipes is 0.8 mm or more.
Only use R32 refrigerant in line woith the
one already loaded in the outdoor unit to
fill the refrigerant in the system.
Additional charge of refrigerant and oil
If the length of the connecting pipe is
increased by 10 m compared to the
standard length, add 5 ml of refrigerant
oil for every 5 m of pipe added.
Method for calculating the amount of
additional refrigerant charge (liquid pipe):
amount of additional refrigerant charge =
additional length of pipe liquid x amount
of additional refrigerant charge per meter.
Use bolts to secure the unit to the floor,
which must be a solid ground. When
installing the unit on the wall or on the
roof, make sure the support is firmly
secured so that it cannot move in the
event of severe vibration or high winds.
Warning: The installation must be
performed in compliance with
NEC/CEC rules by authorized
personnel only.
•Do not install the outdoor unit in
cavities or air vents.
Refrigerating connections
Use equipment and connecting pipes
suitable for R32 refrigerator.
Always write the additional
refrigerant charge on the data label
affixed to the unit outside.
The maximum height difference
between indoor and outdoor unit is
5m.
Wrap with straps all refrigerant pipes
and joints.
