Check of Density Limit
Check the amount of refrigerant in the system and
floor space of the room according to the legislation on
refrigerant drainage. If there is no applicable legislation,
follow the standards described below.
The room in which the air conditioner is to be installed
requires a design that in the event of refrigerant gas
leaking out, its density will not exceed a set limit.
The refrigerant (R410A), which is used in the air conditioner,
is safe, without the toxicity or combustibility of ammonia, and
is not restricted by laws imposed to protect the ozone layer.
(OWEVERSINCEITCONTAINSMORETHANAIRITPOSESTHERISKOF
suffocation if its density should rise excessively. Suffocation
from leakage of refrigerant is almost non-existent. With the
recent increase in the number of high density buildings,
however, the installation of multi air conditioner systems is
on the increase because of the need for effective use of floor
space, individual control, energy conservation by curtailing heat
and carrying power, etc.
Most importantly, the multi air conditioner system is able
to replenish a large amount of refrigerant compared to
conventional individual air conditioners. If a single unit of the
multi air conditioner system is to be installed in a small room,
select a suitable model and installation procedure so that if the
refrigerant accidentally leaks out, its density does not reach the
limit (and in the event of an emergency, measures can be made
before injury can occur).
In a room where the density may exceed the limit, create an
opening with adjacent rooms, or install mechanical ventilation
combined with a gas leak detection device. The density is as
given below.
Total amount of refrigerant (kg)
Min. volume of the indoor unit installed room (m3)
< Density limit (kg/m3)
The density limit of refrigerant which is used in multi air
conditioners is 0.44 kg/m3(ISO 5149).
NOTE
1. The standards for minimum room volume are as follows.
(1) No partition (shaded portion)
(2) When there is an effective opening with the adjacent room
for ventilation of leaking refrigerant gas (opening without
a door, or an opening 0.15% or larger than the respective
floor spaces at the top or bottom of the door).

Precautions for Installation Using New Refrigerant
1. Care regarding tubing
1-1. Process tubing
●Material: Use seamless phosphorous deoxidized copper tube for refrigeration. Wall thickness shall comply with the applicable
legislation. The minimal wall thickness must be in accordance with the table below.
●Tubing size: Be sure to use the sizes indicated in the table below.
FORTHERENEWALTUBINGSIZEREFERTOTHE4ECHNICAL$ATA
●Use a tube cutter when cutting the tubing, and be sure to remove any flash. This also applies to distribution joints (optional).
●When bending tubing, use a bending radius that is 4 times the outer diameter of the tubing or larger.
CAUTION
Use sufficient care in handling the tubing. Seal the tubing ends with caps or tape to prevent dirt,
moisture, or other foreign substances from entering.These substances can result in system
malfunction.

Copper tube Outer diameter 6.35 9.52 12.7 15.88
Wall thickness 0.8 0.8 0.8 1.0
1-2. Prevent impurities including water, dust and oxide from entering the tubing. Impurities can cause R410A refrigerant deterioration
ANDCOMPRESSORDEFECTS$UETOTHEFEATURESOFTHEREFRIGERANTANDREFRIGERATINGMACHINEOILTHEPREVENTIONOFWATERANDOTHER
impurities becomes more important than ever.
2. Be sure to recharge the refrigerant only in liquid form.
2-1. Since R410A is a non-azeotrope, recharging the refrigerant in gas form can lower performance and cause defects in the unit.
2-2. Since refrigerant composition changes and performance decreases when gas leaks, collect the remaining refrigerant and recharge
the required total amount of new refrigerant after fixing the leak.
3. Different tools required
3-1. Tool specifications have been changed due to the characteristics of R410A.
Some tools for R22- and R407C-type refrigerant systems cannot be used.

6-1. Connecting the Refrigerant Tubing
Use of the Flaring Method
Many of conventional split system air conditioners employ the
flaring method to connect refrigerant tubes that run between
indoor and outdoor units. In this method, the copper tubes are
flared at each end and connected with flare nuts.
Flaring Procedure with a Flare Tool
(1) Cut the copper tube to the required length with a tube
cutter. It is recommended to cut approx. 30 – 50 cm longer
than the tubing length you estimate.
(2) Remove burrs at each end of the copper tubing with a tube
reamer or a similar tool. This process is important and
SHOULDBEDONECAREFULLYTOMAKEAGOODFLARE"ESURETO
keep any contaminants (moisture, dirt, metal filings, etc.)
from entering the tubing.
NOTE
When reaming, hold the tube end downward and be sure that
no copper scraps fall into the tube.
(3) Remove the flare nut from the unit and be sure to mount it
on the copper tube.
(4) Make a flare at the end of the copper tube with a flare tool.

together. This is effective for reducing gas leaks.
(3) For proper connection, align the union tube and flare tube
straight with each other, then screw on the flare nut lightly
at first to obtain a smooth match.
Flare nut
Union
●Adjust the shape of the liquid tube using a tube bender at the
installation site and connect it to the liquid tubing side valve
using a flare.
Cautions During Brazing
●Replace air inside the tube with nitrogen gas to prevent
copper oxide film from forming during the brazing
process. (Oxygen, carbon dioxide and Freon are not
acceptable.)
●Do not allow the tubing to get too hot during brazing.
The nitrogen gas inside the tubing may overheat,
causing refrigerant system valves to become damaged.
Therefore allow the tubing to cool when brazing.
●Use a reducing valve for the nitrogen cylinder.
●Do not use agents intended to prevent the formation
of oxide film. These agents adversely affect the
refrigerant and refrigerant oil, and may cause damage or
malfunctions.
6-2. Connecting Tubing Between Indoor and
Outdoor Units
(1) Tightly connect the indoor-side refrigerant tubing extended
from the wall with the outdoor-side tubing.
(2) To fasten the flare nuts, apply specified torque.
●When removing the flare nuts from the tubing connections,
or when tightening them after connecting the tubing, be sure
to use a torque wrench and a spanner.
Outdoor unit
Torque wrench
Spanner

If the flare nuts are over-tightened, the flare may be damaged,
which could result in refrigerant leakage and cause injury or
asphyxiation to room occupants.
●When removing or tightening the gas tube flare nut, use 2
adjustable wrenches together: one at the gas tube flare nut,
and the other at part A.

●For the flare nuts at tubing connections, be sure to use the
flare nuts that were supplied with the unit, or else flare nuts
for R410A (type 2). The refrigerant tubing that is used must
be of the correct wall thickness as shown in the table below.

●In order to prevent damage to the flare caused by over-
tightening of the flare nuts, use the table above as a guide
when tightening.
●When tightening the flare nut on the liquid tube, use a
adjustable wrench with a nominal handle length of 200 mm.
●When tightening the flare nut with the adjustable wrench, do

6-4. Taping the Tubes
(1) At this time, the refrigerant tubes (and electrical wiring
if local codes permit) should be taped together with
armoring tape in 1 bundle. To prevent condensation from
overflowing the drain pan, keep the drain hose separate
from the refrigerant tubing.
(2) Wrap the armoring tape from the bottom of the outdoor
unit to the top of the tubing where it enters the wall. As you
wrap the tubing, overlap half of each previous tape turn.

6-5. Finishing the Installation
After finishing insulating and taping over the tubing, use sealing
putty to seal off the hole in the wall to prevent rain and draft
from entering.
7. LEAK TEST, EVACUATION AND
ADDITIONAL REFRIGERANT
CHARGE
Perform an air-tightness test for this package A/C. Check that
there is no leakage from any of the connections.
Air and moisture in the refrigerant system may have
undesirable effects as indicated below.
●pressure in the system rises
●operating current rises
●cooling (or heating) efficiency drops
●moisture in the refrigerant circuit may freeze and block
capillary tubing
●water may lead to corrosion of parts in the refrigerant
system
Therefore, the indoor unit and tubing between the indoor and
outdoor unit must be leak tested and evacuated to remove any
noncondensables and moisture from the system.
■ Air Purging with a Vacuum Pump (for Test Run)
Preparation
Check that each tube (both liquid and gas tubes) between the
indoor and outdoor units has been properly connected and all
wiring for the test run has been completed. Remove the valve
caps from both the gas and liquid service valves on the outdoor
unit. Note that both liquid and gas tube service valves on the
outdoor unit are kept closed at this stage.
Lo Hi
●The refrigerant charge at the time of shipment is only
guaranteed sufficient for a tubing length of up to 30 m. The
tubing may exceed this length, up to the maximum permitted
length; however, an additional charge is necessary for
the amount that the tubing exceeds 30 m. (No additional
refrigerating machine oil is needed.)
7-1. Leak Test
(1) With the service valves on the outdoor unit closed, remove
the 6.35 mm flare nut and its bonnet on the gas tube
service valve. (Save for reuse.)
(2) Attach a manifold valve (with pressure gauges) and dry
nitrogen gas cylinder to this service port with charge
hoses.
CAUTION
Use a manifold valve for air purging. If it is not available,
use a stop valve for this purpose. The “Lo” knob of the
manifold valve must always be kept closed.
(3) Pressurize the system up to 4.15 MPa {42 kgf/cm2G} with
dry nitrogen gas and close the cylinder valve when the
gauge reading reaches 4.15 MPa {42 kgf/cm2G}. Then, test
for leaks with liquid soap.
CAUTION
To avoid nitrogen entering the refrigerant system in a
liquid state, the top of the cylinder must be higher than
the bottom when you pressurize the system. Usually, the
cylinder is used in a vertical standing position.
$OALEAKTESTOFALLJOINTSOFTHETUBINGBOTHINDOORAND
OUTDOORANDBOTHGASANDLIQUIDSERVICEVALVES"UBBLES
indicate a leak. Wipe off the soap with a clean cloth after a
leak test.
(5) After the system is found to be free of leaks, relieve the
nitrogen pressure by loosening the charge hose connector
at the nitrogen cylinder. When the system pressure is
reduced to normal, disconnect the hose from the cylinder.

CAUTION
Use a cylinder specifically designed for use with R410A.
Lo Hi
7-3. Charging Additional Refrigerant
●Charge additional refrigerant (calculated from the liquid tube
length as shown in “1-5. Tubing Size”) using the liquid tube
service valve. (Fig. 7-1)
●Use a balance to measure the refrigerant accurately.
●If the additional refrigerant charge amount cannot be
charged at once, charge the remaining refrigerant in liquid
form by using the gas tube service valve with the system in
Cooling mode at the time of test run. (Fig. 7-2)
* If an additional refrigerant charge has been performed, list the
refrigerant tubing length and amount of additional refrigerant
charge on the product label (inside the panel).

7-4. Finishing the Job
(1) With a hex wrench, turn the liquid tube service valve stem
counterclockwise to fully open the valve.
(2) Turn the gas tube service valve stem counterclockwise to
fully open the valve.
CAUTION
To avoid gas from leaking when removing the charge hose,
make sure the stem of the gas tube is turned all the way

port (7.94 mm) slightly to release the pressure, and then
remove the hose.
(4) Replace the 7.94 mm flare nut and its bonnet on the gas
tube service port and fasten the flare nut securely with an
adjustable wrench or box wrench. This process is very
important to prevent gas from leaking from the system.
(5) Replace the valve caps at both gas and liquid service
valves and fasten them securely.

8-13. Caution for Pump Down
Pump down means refrigerant gas in the system is returned
to the outdoor unit. Pump down is used when the unit is to be
moved, or before servicing the refrigerant circuit.
CAUTION
●This outdoor unit cannot collect more than the rated
refrigerant amount as shown by the nameplate on the
back.
●If the amount of refrigerant is more than that
recommended, do not conduct a pump down. In this
case use another refrigerant collecting system.
●Pay a special attention to the rotating of the fan while
operating.
How to perform Pump-Down (Refrigerant
recovery) properly
(1) Stop operation of the unit (cooling, heating etc.).
(2) Connect the pressure gauge to the service port of the gas
tubing valve.
