of the unit may result in electric
shock or fire. For repair, contact an
authorized service dealer.
Rated voltage of this air conditioner
is 208/230V, 60Hz. If voltage is too
low, the compressor will vibrate
excessively and this may damage
the cooling system. If the voltage is
too high, it may damage electrical
components.
Otherwise,it may cause electric
shock or damage.
Make sure the brackets supporting
the outdoor unit (compressor) are
firmly fixed.
Never step or walk on the top of the
outdoor unit, nor put something on it.
Grounding wire: this unit must at all
times be connected by a wire to a
grounding device. This has to be
verified by a certified electrician.
If not secured, the compressor
could fall down, causing injurries
and damages.
Turn power off when the air condi-
tioner will not be used for a long
period of time.
Never damage the power cables. If
power cables are damaged, do not
use the air conditioner.

INSTALLING THE OUTDOO UNIT
BLEEDING
INSTALLE
INSTALLE
LOCATION
Use bolts to secure the unit to a flat, solid floor.
When mounting the unit on a wall or the roof,
make sure the support is firmly secured so that it
cannot move in the event of intense vibrations or
a strongwind.
Do not install the outdoor unit in pits or air vents
Humid air left inside the refrigerant circuit can cause com-
pressor malfunction. After having connected the indoor
and outdoor units, bleed the air and humidity from the
refrigerant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and
3-way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling.
Stop the vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds. Check all the joints for leaks using
liquid soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves.
Disconnect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.
Caution: installation must be performed in accor-
dance with the NEC/CEC and only by authorized
and certified personnel.
Install the drain fitting and the drain hose
(for model with heat pump only)
Condensation is produced and flows from the outdoor
unit when the appliance is operating in the
heating mode. In order not to disturb neighbours
and to respect the environment,install a drain fitting
and a drain hose to channel the condensed water.
Install the drain fitting and rubber washer on the out-
door unit chassis and connect a drain hose to it as
shown in the figure.
Use suitable connecting pipes and
equipment for the refrigerant R410A.
The refrigerant pipes must not exceed the maximum
heights 10m(18 x2&24 x2&24 x3&28 x4&30 X4
&36 X5&42 X5).
Wrap all the refrigerant pipes and joints.
Tighten the connections using two wrenches
working in opposite directions.
