HOW TO TAKE OUT FRONT GRILLE
Whenreinstalling the front grille, first set the vertical
airflow direction louver to the horizontal position and
then carry out above steps 2 - 3 in the...

10.3.2. INSTALL THE OUTDOOR UNIT
 • After selecting the best location , start installation according
to Indoor/Outdoo r Unit Installation Diagram.
 1. Fix the unit on concrete or rigid frame firmly and horizontally
by bolt nut. (ø10 mm).
 2. When installin g at roof, please conside r strong wind and
earthquake. Please fasten the installation stand firmly with
bolt or nails.
CUTTING AND FLARING THE PIPING
 1. Please cut using pipe cutter and then remove the burrs.
 2. Remove the burrs by using reamer. If...

10.3.4. EVACUATION OF THE EQUIPMENT
WHENINSTAL LING AN AIR CONDITIONER, BE SURE TO EVACU ATE THE AIR INSIDE THE INDOOR UNIT AND PIPES in the
followin g procedure.
 1. Connec t a charging hose with a push pin to the Low and High side of a charging set and the service port of the 3-way valve.
 • Be sure to connect the end of the charging hose with the push pin to the service port.
 2. Connec t the center hose of the charging set to a vacuum pump with check valve, or vacuum pump and vacuum pump adaptor.
 3....

DISPOSAL OF OUTDOOR UNITDRAIN WATER
 • If a drain elbow is used, the unit should be placed on a
stand which is taller than 3 cm.
 • If the unit is used in an area where temperature falls below
0°C for 2 or 3 days in succession, it isrecommended not to
use a drain elbow, for the drain water freezes and the fan
will not rotate.
CHECK THE DRAINAGE
 • Open front panel and remove air filters.
(Drainage checking can be carried out without removing the
front grille.)
 • Pour a glass of water into the drain...

11 Installation And Servicing Air Conditioner Using R410A
11.1. Outline
11.1.1. About R410ARefrigerant
 1. Converting air conditio ners to R410A
Since it was declared in1974 that chlorofluoroca rbons (CFC), hydro chlorofluoroca rbons (HCFC) and other substances pose a
destructive danger to the ozone layer in the earth´s upper stratosphere (20 to 40 km above the earth), measures have been
taken around the world to prevent this destruction.
The R22 refrigerant which has conventionally been used in ACs is...

 d. R410A refrigerating machine oil
Conventionally , mineral oil or a synthet ic oil such as alkylbe nzene has been used for R22 refrigerating machine oil. Becaus e
of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the
refrigerating machine oil to collect in the refrigerating cycle. For this reason, polyest er and other synthet ic oils which have
a high compatibility with R410A are used as refrigerating machine oil.
Becaus e of the high...

11.2.2. R410ATools
 1. Copper tube gauge for clearance adjustment
(used when flaring with the conventional flaring tool (clutch
type))
 • This gauge makes iteasy to set the clearance for the
copper tube to 1.0-1.5 mm from the clamp bar of the
flaring tool.
 2. Flaring tool (clutch type)
 • In the R410A flaring tool, the receiving hole for the
clamp bar is enlarged so the clearance from the clamp
bar can be set to 0-0.5 mm, and the spring inside the
tool is strengthened to increase the strength of the...

 5. Charging hose
 • The pressure resistance of the charging hose has been
raised to match the higher pressure of R410A . The hose
material has also been changed to suit HFC use, and
the size of the fitting has been changed to match the
manifold ports.
 6. Vacuum pump adaptor
 • W hen using a vacuum pump for R410A , it is necessary
to install an electromagnetic valve to prevent the
vacuum pump oil from flowing back into the charging
hose. The vacuum pump adaptor is installed for that
purpose. if the...

 8. Electronic scale for refrigerant charging
 • Because of the high pressure and fast vaporizing speed
of R410A , the refrigerant cannot be held in a liquid
phase inside the charging cylinde r when charging is
done using the charging cylinde r method, causing
bubble s to form in the measurement scale glass and
making it difficult to see the reading. (Naturally, the
conventional R22 charging cylinde r cannot be used
because of the differen ces in the pressure resistance,
scale gradation, connecting port...

11.3. Refrigerant Piping Work
Whenworking with refrigerant piping, the followin g points must
be carefully observed: no moisture od dust must be allowed to
enter the piping, and there must be no refrigerant leaks.
 1. Procedure and precautions for flaring work
 a. Cut the pipe
Use a pipe cutter, and cutslowly so the pipe will not be
deformed.
 b. Remove burrs and clean shavings from the cut surface
If the shape of the pipe end is poor after removing burrs,
or if shavings adhere to the flared area, it may...
