Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.
This air conditioner has the structure designed
to drain water collected from dew, which forms
on the back of the indoor unit, to the drain pan.
Therefore, do not store the power cord and other
parts at a height above the drain guide.

OUTDOOR UNIT
Installation Place
• A place which provides the spaces around the outdoor unit as shown in the
diagram
• A place which can bear the weight of the outdoor unit and does not allow an
increase in noise level and vibration
• A place where the operation noise and discharged air do not disturb your
neighbors
• A place which is not exposed to a strong wind
• A place free of a leakage of combustible gases
• A place which does not block a passage
• When the outdoor unit is to be installed in an elevated position, be sure to
secure its feet.
• The allowable pipe length is up to 15 m
• The allowable height of outdoor-unit installation site is up to 5 m for
RAS-10PASG -T and 6 m for RAS-13PASG -T
• A place where the drain water does not raise any problems
CAU I N
1. Install the outdoor unit without anything blocking the air discharging.
2. When the outdoor unit is installed in a place always exposed to strong
wind like a coast or on a high storey of a building, secure the normal fan
operation using a duct or a windshield.
3. In particularly windy areas, install the unit such as to avoid admission of
wind.
4. Installation in the following places may result in trouble.
Do not install the unit in such places.
• A place full of machine oil
• A saline-place such as the coast
• A place full of sulfi de gas
• A place where high-frequency
waves are likely to be generated
as from audio equipment, welders,

The operating pressure of R32
is higher than that of R22 (approx.
1.6 times). It is therefore necessary
to fi rmly tighten the fl are pipe
connecting sections (which connect
the indoor and outdoor units) up to the
specifi ed tightening torque. Incorrect
connections may cause not only a
gas leakage, but also damage to the
refrigeration cycle.

vac atin
After the piping has been connected to the indoor unit, you can perform the
air purge together at once.
AI PU
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not use the refrigerant in the outdoor unit. For details,
see the manual of the vacuum pump.
Be sure to use a vacuum pump with counter-fl ow prevention function so that
inside oil of the pump does not fl ow backward into pipes of the air conditioner
when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which use R32,
refrigeration cycle trouble may result.)
1. Connect the charge hose from the manifold valve to the service port of the
packed valve at gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to start evacuating. Perform evacuating for
about 15 minutes if the piping length is 20 meters.
(15 minutes for 20 meters)
(assuming a pump capacity of 27 liters per minute) Then confi rm that the
compound pressure gauge reading is –101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold valve.
6. Open fully the valve stem of the packed valves (both gas and liquid sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
