Outdoor Unit
◆The outdoor unit must not be placed on its side or upside down, as the com-
pressor lubrication oil will run into the cooling circuit and seriously
damage the unit.
◆Choose a location that is dry and sunny, but not exposed to direct sunlight or
strong winds.
◆Do not block any passageways or thoroughfares.
◆Choose a location where the noise of the air conditioner when running and
the discharged air do not disturb any neighbours.
◆Choose a position that enables the pipes and cables to be easily connected
to the indoor unit.
◆Install the outdoor unit on a flat, stable surface that can support its weight
and does not generate any unnecessary noise and vibration.
◆Position the outdoor unit so that the air flow is directed towards the open
area.
◆Maintain sufficient clearance around the outdoor unit, especially from a radio,
computer, stereo system, etc.
◆If the outdoor unit is installed at a height, ensure that its base is firmly fixed in
position.
◆Make sure that the water dripping from the drain hose runs away correctly
and safely.

- If the power is unbalanced greatly, it may shorten the life
of the condenser. If the unbalanced power is exceeded
over 4% of supply rating, the indoor unit is protected,
stopped and the error mode indicates.
◆To protect the product from water and possible shock, you
should keep the power cable and the connection cord of the
indoor and outdoor units in the iron pipe.
◆ Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be
incorporated in the fixed wiring(≥3mm).

The air in the indoor unit and in the pipe must be purged. If air remains in the
refrigeration pipes, it will affect the compressor, reduce to cooling capacity and
could lead to a malfunction. Refrigerant for air purging is not charged in the
outdoor unit. Use Vacuum Pump as shown at the figure.
Connect each assembly pipe to the appropriate valve on the outdoor unit
and tighten the flare nut.

Referring to the illustration opposite, tighten the flare nut on section B first
manually and then with a torque wrench, applying the following torque.

Purge the air from the system using vacuum pump for about 10 minutes.
◆Close the valve of the low pressure side of manifold gauge clockwise.
◆Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
10 minutes.
This procedure is very important in order to avoid gas leak.
◆Turn off the vacuum pump.
◆Remove the hose of the low pressure side of manifold gauge.

Mount the valve stem nuts and the service port cap to the valve, and
tighten them at the torque of 183kgf•cm with a torque wrench.

Cutting / Flaring the pipes
Make sure that you have the required tools available (pipe cutter, reamer,
flaring tool and pipe holder).
If you wish to shorten the pipes, cut it with a pipe cutter, taking care to
ensure that the cut edge remains at a 90°angle with the side of the pipe.
Refer to the illustrations below for examples of edges cut correctly and
incorrectly.

To prevent any gas from leaking out, remove all burrs at the cut edge of the
pipe, using a reamer.

To avoid condensation problems, place an insulator around each
refrigerant pipe.

If you have not insulated the refnet joint, you should insulate it.
For the refnet joint insulation, refer to page 16.

the instructions below.
Make space more than 50mm between the bottom of the outdoor unit
and the ground for installation of the drain hose, as shown in figure.

Adding refrigerant
The outdoor unit is loaded with sufficient refrigerant for the standard
piping. Thus, refrigerant must be added if the piping is lengthened.
This operation can only be performed by a qualified refrigeration
specialist. For quantity of adding refrigerant, refer to page 21.
Check that the stop valve is closed entirely.

If you cannot charge the refrigerant according to the upper steps,
following these:
3-1 Open both liquid stop valve and gas stop valve.
3-2 Operate the air conditioner by pressing the K2 key on the outdoor
