getting mixed into the system.
■
Tight
R-410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R-410A can contribute slightly to the greenhouse
effect if it is released. Therefore we should take
special attention to check the tightness of the
installation.
Read "6. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar (for R-407C
units: 3.3 MPa or 33 bar), pipes of larger wall thickness may
be required. Refer to paragraph "6.1. Selection of piping

PIPING
6.1.
1.
Foreign materials inside pipes (including oils for fabrication) must be
30 mg/10 m or less.
Use R-410A to add refrigerant.
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.
2.
Use the following material specification for refrigerant piping:
■ Size: determine the proper size referring to chapter
"6.3. Example of connection" on page 8.
■ Construction material: phosphoric acid deoxidized seamless
copper for refrigerant.
CAUTION TO BE TAKEN WHEN BRAZING
REFRIGERANT PIPING
■ Temper grade: use piping with temper grade in function of the
pipe diameter as listed in below table.
Do not use flux when brazing copper-to-copper refrigerant
piping. (Particularly for the HFC refrigerant piping)
Therefore, use the phosphor copper brazing filler metal
(BCuP) which does not require flux.
Pipe Ø
Flux has extremely harmful influence on refrigerant piping
systems. For instance, if the chlorine based flux is used, it
will cause pipe corrosion or, in particular, if the flux
contains fluorine, it will damage the refrigerant oil.
Temper grade of piping material
≤15.9
O
≥19.1
1/2H
O = Annealed

■ The pipe thickness of the refrigerant piping should comply
with relevant local and national regulations. The minimal pipe
thickness for R-410A piping must be in accordance with the
table below.
Be sure to perform a nitrogen blow when brazing.
(Brazing without performing nitrogen replacement or
releasing nitrogen into the piping will create large
quantities of oxidized film on the inside of the pipes,
adversely affecting valves and compressors in the
refrigerating system and preventing normal operation.)

Make sure to use the particular branches of piping that have been
selected referring to chapter "6.3. Example of connection" on page 8.
4.
In case the required pipe sizes (inch sizes) are not available, it is also
allowed to use other diameters (mm sizes), taken the following into
account:
Installation tools:
Make sure to use installation tools (gauge manifold
charge hose, etc.) that are exclusively used for R-410A
installations to withstand the pressure and to prevent
foreign materials (e.g. mineral oils such as SUNISO
and moisture) from mixing into the system.
(The screw specifications differ for R-410A and
R-407C.)
■ select the pipe size nearest to the required size.
■ use the suitable adapters for the change-over from inch to
mm pipes (field supply).

Checking of unit and installation conditions
1
Be sure to check the following:
2
Pressurize the liquid and gas pipes to 4.0 MPa (40 bar) (do not
pressurize more than 4.0 MPa (40 bar)). If the pressure does not
drop within 24 hours, the system passes the test. If the pressure
drops, check where the nitrogen leaks from.
■
Vacuum drying: Use a vacuum pump which can evacuate to
–100.7 kPa (5 Torr, –755 mm Hg)
1.
Evacuate the system from the liquid and gas pipes by using a
vacuum pump for more than 2 hours and bring the system to
–100.7 kPa. After keeping the system under that condition for more
than 1 hour, check if the vacuum gauge rises or not. If it rises, the
system may either contain moisture inside or have leaks.
2.
Following should be executed if there is a possibility of moisture
remaining inside the pipe (if piping work is carried out during the
raining season or over a long period of time, rainwater may enter the
pipe during work).
After evacuating the system for 2 hours, pressurize the system to
0.05 MPa (vacuum break) with nitrogen gas and evacuate the
system again using the vacuum pump for 1 hour to –100.7 kPa
(vacuum drying). If the system cannot be evacuated to –100.7 kPa
within 2 hours, repeat the operation of vacuum break and vacuum
drying.
Then, after leaving the system in vacuum for 1 hour, confirm that the
vacuum gauge does not rise.
Make sure to perform airtightness test and vacuum
drying using the service ports of the stop valve shown
in the table below.
NOTE

Pipe insulation
After finishing the leak test and vacuum drying, the piping must be
insulated. Take into account the following points:
■
Make sure to insulate the connection piping and refrigerant
branch kits entirely.
■
Be sure to insulate liquid and gas piping (for all units).
■
Use heat resistant polyethylene foam which can withstand a
temperature of 70°C for liquid side piping and polyethylene foam
which can withstand a temperature of 120°C for gas side piping.
■
If you think the temperature and the relative humidity around the
cooling pipes might exceed 30°C and RH 80%, reinforce the
insulation of the cooling pipes (at least 20 mm thick).
Condensation might be formed on the surface of the insulation.
■
If there is a possibility that condensation on the stop valve might
drip down into the indoor unit through gaps in the insulation and
piping because the outdoor unit is located higher than the indoor
unit this must be prevented by sealing up the connections. See
figure 8.

Using a megatester for 500 V, check that the insulation

500 V DC between the power terminals and earth. Never use
the megatester for the transmission wiring (between outdoor
and indoor unit, outdoor and COOL/HEAT selector, etc.).
6.7.
Stop valve operation procedure
Do not open the stop valve until steps 1~6 of
"6.6. Checking of unit and installation conditions" on
page 10 are completed. If the stop valve is left open
without turning on the power, it may cause refrigerant to
build up in the compressor, leading to insulation
degradation.

2.
Turn it until the shaft stops.
Do not apply excessive force to the stop valve. Doing so may break
the valve body, as the valve is not a backseat type. Always use the
special tool.

Make sure to tighten the cap securely.
Closing stop valve
1.
Remove the cap and turn the valve clockwise with the hexagon
wrench.
2.
Securely tighten the valve until the shaft contacts the main body seal.
3.
Make sure to tighten the cap securely.
For the tightening torque, refer to the table below.
To avoid compressor breakdown. Do not charge the refrigerant
more than the specified amount.
■
This outdoor unit is factory charged with refrigerant and
depending on pipe sizes and pipe lengths some systems require
additional charging of refrigerant. (Refer to "How to calculate the
additional refrigerant to be charged" on page 9).
■
Make sure to use installation tools you exclusively use on
R-410A installations to withstand the pressure and to prevent
foreign materials from mixing into the system.
■
Charge the refrigerant to the liquid pipe in its liquid state. Since
R-410A is a mixed refrigerant, its composition changes if
charged in a state of gas and normal system operation would no
longer be assured.
■
Before filling, check whether the tank has a siphon attached or
not.

■
Additional refrigerant charge
Refrigerant cannot be charged until field wiring has been
completed.
Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant (R-410A) is charged.
Charging while the outdoor unit is operating
1
Completely open the gas line stop valve.
Valve A must be left fully closed.
Make sure the liquid stop valve is totally shut. If it is open, the
refrigerant cannot be charged.
Charge the additional refrigerant in its liquid state through the
service port of the liquid line stop valve.

After the vacuum drying is finished, charge the additional
refrigerant in its liquid state through the liquid stop valve service
port taking into account following instructions:
- Check that gas and liquid stop valves are closed.
- Stop the compressor and charge the specified weight of
refrigerant.
If the total refrigerant cannot be charged while the outdoor
unit is at standstill, it is possible to charge the refrigerant by
operating the outdoor unit using the refrigerant charge
function (refer to "Setting mode 2" on page 18).
Refrigerant may only be charged after performing the leak
test and the vacuum drying (see above).
When charging a system, care shall be taken that its
maximum permissible charge is never exceeded, in view of
the danger of liquid hammer.
Determine the weight of refrigerant to be charged additionally
referring to the item "Additional refrigerant charge" in "How to
calculate the additional refrigerant to be charged" on page 9 and
fill in the amount in the "Additional refrigerant charge label"
attached to the unit.

9. SERVICE
MODE OPERATION
Vacuuming method
At the first installation, this vacuuming is not required. It is required
only for repair purposes.
1
10. CAUTION
(Points to note in connection with refrigerant leaks.)
Introduction
The installer and system specialist shall secure safety against
leakage according to local regulations or standards. The
following standards may be applicable if local regulations are
not available.
The VRV System, like other air conditioning systems, uses R-410A
as refrigerant. R-410A itself is an entirely safe non-toxic, noncombustible refrigerant. Nevertheless care must be taken to ensure
that air conditioning facilities are installed in a room which is
sufficiently large. This assures that the maximum concentration level
of refrigerant gas is not exceeded, in the unlikely event of major leak
in the system and this in accordance to the local applicable
regulations and standards.
Maximum concentration level
The maximum charge of refrigerant and the calculation of the
maximum concentration of refrigerant is directly related to the
humanly occupied space in to which it could leak.
The unit of measurement of the concentration is kg/m 3 (the weight in
kg of the refrigerant gas in 1 m3 volume of the occupied space).
Compliance to the local applicable regulations and standards for the
maximum allowable concentration level is required.
According to the appropriate European Standard, the maximum
allowed concentration level of refrigerant to a humanly space for
R-410A is limited to 0.44 kg/m 3.
When the unit is at standstill and under the setting mode 2, set
the required function B (refrigerant recovery operation/
vacuuming operation) to ON (ON).
- After this is set, do not reset the setting mode 2 until the
vacuuming is finished.
- The H1P led is on and the remote controller indicates
(test operation) and
(external control) and the
operation will be prohibited.
2
Evacuate the system with a vacuum pump.
3
Press the BS1 MODE button and reset the setting mode 2.

Refrigerant recovery operation method
by a refrigerant reclaimer
1
FOR REFRIGERANT LEAKS
When the unit is at standstill and under the setting mode 2, set
the required function B (refrigerant recovery operation/
vacuuming operation) to ON (ON).
- The indoor unit and the outdoor unit expansion valves will
fully open and some solenoid valves will be turned on.
- The H1P led is on and the remote controller indicates
(test operation) and
(external control) and the
operation will be prohibited.
2
Cut off the power supply to the indoor units and the outdoor unit
with the circuit breaker. After the power supply to one side is cut
off, cut off the power supply to the other side within 10 minutes.
Otherwise, the communication between the indoor and outdoor
unit may become abnormal and the expansion valves will be
completely closed again.
3
Recover the refrigerant by a refrigerant reclaimer. For details,
see the operation manual delivered with the refrigerant
reclaimer.

maximum concentration.
4
Dealing with the situations where the result exceeds the
maximum concentration level.
Where the installation of a facility results in a concentration in
excess of the maximum concentration level then it will be
necessary to revise the system.
Please consult your supplier.
