1 GENERAL INFORMATION

1.1 Specific features

(1) The long piping makes the location of the inside and units flexible.

¡ No need for additional charge of refrigerant : 40 type · 30m, 45 type · 20m, 48 type · 40m, 60 type · 30m, 80 type · 40m

¡ Maximum piping length : 40 type · 30m, 45 type · 30m, 48 type · 40m, 60 type · 40m, 80 type · 70m

(2) Connectable indoor capacity

Number of connectable units : 40 type · 2 units, 45 type · 2 units, 48 type · 3 units, 60 type · 3 units, 80 type · 4 units

Total of indoor units (class kW) : 40 type · 5.6 kW, 45 type · 7.0 kW, 48 type · 8.5 kW, 60 type · 11.0 kW, 80 type · 13.5 kW

(3) Indoor units are available with 7 capacities.

7 capacities ................ 20, 22, 25, 28, 35, 50, 60

Types ......................... Wall mounted type (SKM).

4-way ceiling cassette type (STM).

Ducted type (SRRM).

(4) Inverter (Frequency converter) for multi-steps power control

¡ Heating / Cooling

The rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor unit

fans controlled to changes in frequency, thus controlling the power.

¡ Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the

unit has stabilized.

(5) Fuzzy control

Fuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting temperature

in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.

(6) Self diagnosis function

We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as

follows. (See page 95)

4.9 Outline of automatic operation

(1) Determination of operation mode

The unit checks the room temperature and the outdoor air temperature after operating the indoor and outdoor blowers for 20

seconds, determines the operation mode and the room temperature setting correction value, and then enters in the automatic

operation.

(2) The unit checks the temperature every hour after the start of operation and, if the result of check is not same as the previous

operation mode, changes the operation mode.

(3) When the unit is started again within one hour after the stop of automatic operation or when the automatic operation is selected

during heating, cooling or dehumidifying operation, the unit is operated in the previous operation mode.

(4) Setting temperature can be adjusted within the following range. There is the relationship as shown below between the signals of the

wireless remote control and the setting temperature.

¡ Though the precautionary points indicated herein are divided under two headings, WARNING and CAUTION , those points

which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the

WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the CAUTION

section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.

¡ After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain

operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.

Moreover, ask the customer to keep this sheet together with the owner’s manual.

WARNING

¡ To disconnect the appliance from the mains supply this appliance must be connected to the mains by means of

a circuit breaker or a switch (use a recognized 25A) with a contact separation of at least 3mm.

¡ The appliance shall be installed in accordance with national wiring regulations.
¡ This system should be applied to places as households, residences and the like. Application to inferior environ-

ment such as engineering shop could cause equipment malfunction.

¡ Please entrust installation to either the company which sold you the equipment or to a professional contractor.

Defects from improper installations can be the cause of water leakage, electric shocks and fires.

¡ Execute the installation accurately, based on following the installation manual. Again, improper installations can

result in water leakage, electric shocks and fires.

¡ For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insuffi-

cient, injury can result from a falling of the unit.

¡ For electrical work, please see that a licensed electrician executes the work while following the safety standards

related to electrical equipment, and local regulations as well as the installation instructions, and that only exclu­sive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks
and fires.

¡ Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted

to the terminal connection part, through properly securing it. Improper connection or securing can result in heat
generation or fire.

¡ Ta ke care that wiring does not rise upward ,and accurately install the lid/service panel.It’s improper installation

can also result in heat generation or fire.

¡ When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the

designated refrigerant (R410A) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.

¡ Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this

company can result in water leakage, electric shock, fire and refrigerant leakage.

¡ Ventilate the work area when refrigerant leaks during the operation.

Coming in contact with fire, refrigerant could generate toxic gas.

¡ Confirm after the foundation construction work that refrigerant does not leak.

If coming in contact with fire of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the
room could generate toxic gas.

¡ In joining pipes, do not use conventional (R22) pipng flare nuts, etc. The use of conventional pipng materials may

lead to the rapture of piping due to higher pressure used for the refrigerant cycle and possible personal injury.
(Use only piping material designed specifically for R410A)

¡ If the power cord becomes damaged, ask your dealer or qualified enginner to install the replacement to avoid accidents.
¡ Beware of the Alminume fins, the Flare of pipes, Top screw, and etc. You could injure your fingers, etc.
¡ When working at high place, be careful not to drop tools.

Improper placement of ground wires can result in electric shock.

¡ The installation of an earth leakage breaker is necessary depending on the established location of the unit.

Not installing an earth leakage breaker may result in electric shock.

¡ Do not install the unit where there is a concern about leakage of combustible gas.

The rare even of leaked gas collecting around the unit could result in an outbreak of fire.

¡ For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it

to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

¡ Do not install an outdoor unit where rodents or other small animals are likely to inhabit.

Small animals entering the unit can cause a unit breakdown or an accident involving smoke
generation and/or ignition, if they touch electrical parts in side. Please ask the customer to keep
its surroundings clean.

A . When hanging from the ceiling

a) When installing on a 2

’

x 2’ grid ceiling, if necessary, please

detach the T bar temporarily before you install it. When

installing on a conventional ceiling, cut an installation opening

(660mm x 660mm) in the ceiling. When installing on a conventional

ceiling, cut an opening (Min 450 x 450) for inspection purposes.

b) Determine the positions of hanging bolts (530 x 530).

c) Use four hanging bolts, each fastened in such a manner that it can withstand pull force of 50kgf.

d) Make hanging bolts to the length that leaves approximately 45 mm of them above the ceiling. In hoisting the unit

main body in, temporarily fasten the four lower nuts of the hanging bolts approx. 93 mm from the ceiling and the

four upper nuts at positions sufficiently far from the lower nuts so that they may not hamper installation work when

the unit is hoisted in or the height is adjusted.

e) Put the unit on an angle.

f) After hoisting in the unit , attach level gauges supplied as accessories and

determine the unit position (height). To adjust height, use the four lower nuts

with the four upper nuts left loose. Please make sure that the unit's four hanging

fixtures touch the four lower nuts and washers evenly without any play.

g) Please make sure that the unit main body is installed levelly. Level must be checked with

the level gauge or a clear hose filled with water. (A tolerable height difference at an

end of the unit is within 3 mm)

h) After you have adjusted the height and level of the unit, fasten the four upper nuts to fix the unit.

B. When embedded into ceiling

1. Determine the positions of hanging bolts (530 × 530).

The pitch center of a hanging bolt must accord with the center of the unit.

2. Use four hanging bolts, each fastened in such a manner that it can withstand pull force of 50kgf.

3. Fix the unit as per A-e ~ g previous page.

5) Drainage

¡ Glue the drain hose supplied as an accessory and a VP-25 joint before lifting

the unit.

¡ The drain hose is to provide a buffer to absorb a slight dislocation of the unit or

the drain piping during installation work. If it is subject to abuse such as being

bent or pulled deliberately, it may break, which will result in a water leak.

¡ Care must be taken so as not to allow an adhesive to run into the drain hose.

When it is hardened, it can cause a breakage of a flexible part, if the flexible

part receives stress.

¡ Use VP-25 general-purpose hard PVC pipes for drain piping.
¡ Insert the drain hose supplied as an accessory (soft PVC end) to the stepped

part of the unit's drain socket and then fasten it with the clamp also supplied as

an accessory.

<Adhesive must not be used>

¡ Glue a VP-25 joint (to be procured locally) to join it with the drain hose (hard

PVC end) and then glue a VP-25 (to be procured locally) to the joint.

¡ Give the drain piping a descending grade (1/50 - 1/100) and never create a

bump to go over or a trap.

¡ In connecting drain pipes, care must be taken so as not to apply force to the

unit side piping and fix the pipe at a point as close to the unit as possible.

¡ Do not create an air vent under any circumstances.
¡ When drain piping is implemented for more than one unit, provide a collecting

main about 100 mm below the units' drain outlets from which it collects drain.

Use a VP-30 or larger pipe for a collecting main.

¡ Do not fail to provide heat insulation at the following two points because they

can cause dew condensation and a resultant water leak.

• Drain socket

After a drain test is completed, apply a pipe cover (small: accessory) onto the

drain socket, cover the pipe cover (small), the clamp and part of the drain

hose with a pipe cover (large: accessory) and wrap it with a tape completely

without leaving any gaps.

(Cut pipe covers into appropriate shapes)

• Hard PVC pipes laid indoor

¡ Since a drain pipe outlet can be raised up to 60 cm from the ceiling, use el-

bows, etc. to install drain pipes, if there are obstacles preventing normal drain

pipe arrangement. When the drain pipe is raised at a point far from a unit, it can

cause an overflow due to a back flow of drain upon stoppage, so arrange piping

to keep the dimensions specified in the illustration shown on the right.

¡ Install the drain pipe outlet where no odor is likely to be generated.
¡ Do not lead the drain pipe into a ditch where the generation of harmful gas

such as sulfuric gas or flammable gas is expected. A failure to observe this

instruction may cause such harmful or flammable gas to flow into the room.

Notes • When a hanging bolt exceeds 1.3 m in length, use an M10 bolt and give it reinforcements such as braces.

(2) Connection of refrigerant piping

¡ The service valve corresponding to each indoor unit is as illustrated in the right figure.

¡ Regarding the change in the sizes of gas side pipes (usage of the variable joints); if a

5.0 and 6.0 kW class indoor unit (gas side pipe 12.7) is going to be connected to the

service valves (9.52), variable joints available as accessories must be applied to the gas

side service valves.

[Examples of use of variable diameter joints]

Connection of indoor unit of Class 5.0 to A unit.

¡ Securely fit the copper packing between the service valve and the variable diameter joint to prevent shifting.

¡ Cover the pipes with tape so that dust and sand do not enter the pipe until they are connected.

[Connection of pipes]

¡ When connecting the pipes to the outdoor unit, be careful about the discharge of fluorocarbon gas or oil.

¡ Make sure to match the pipes between the indoor unit and the outdoor unit with the correct service valves.

(1) Preparations

¡ Remove the flare nut (from both

liquid and gas sides).

(3) Air purging

(a) Remove the cap on both gas and liquid sides before starting operation.
(b) After completing the operation, do not forget to tighten the cap (gas may leak).
(c) Conduct air purging for all connected indoor units.
¡ Since the system uses service ports differing in diameter from those found on the conventional models, a charge hose (for R22)

presently in use is not applicable.
Please use one designed specifically for R410A

¡

Please use an anti-reverse flow type vacuum pump adapter so as to prevent vacuum pump oil from running back into the system.
Oil running back into an air-conditioning system may cause the refrigerant cycle to break down.

Note: Fully open the service valves (on both liquid and gas sides) after completing air purging

To protect the global environment, use a vacuum pump that do not release flourocarbon gas into the atmosphere.
When a vacuum pump cannot be used due to certain conditions for installation, sufficient refrigerant is available for air
purging with refrigerant for the outdoor unit.

Procedure

1 Secure all flare nuts on both indoor and outdoor

sides to prevent leaks from the pipes.

2 Connect the service valves, charge hose, manifold

valve and vacuum pump as shown in the right fig­ure.

3 Fully open the handle Lo for the manifold valve,

and pump a vacuum for 15 minutes. Ensure that the
meter is indicating -0.1 MPa (-76cmHg).

4 After vacuuming, fully open the service valve (both

liquid and gas sides) with a hexagon wrench.

5 Remove the charge hose from service port.
6 Repeat the above steps 1 ~ 5 for all connected

indoor units.

7 Ensure that there are no gas leaks from the joints in

the indoor and outdoor units.

(d) Installation procedure

1) Mount the duct for the air inlet grille to the indoor unit

using the 10 tapping screws provided. The tapping screws

on the drain pan receiver side are also used for mounting

the duct for the air inlet grille. They must first be removed

and reinstalled after the duct for the air inlet grille is in

place. A guideline for the height is to secure the assembly

so that the lower surface of the duct for the intake grille is

approximately 10 mm above the bottom surface of the

ceiling.

2) Remove the center screw for the air inlet grille and open

the grille as shown in the illustration. Next, insert the air

inlet grille into the duct for the air inlet grille and secure it

with the pan-head screws (the long screws).

3) Use the pan-head screws to make the small adjustments

in height. The height dimension on the installation dia-

gram allows for adjustment within range of 80 to 100 mm.

If the pan-head screws are completely tightened, the height

will be 80 mm.

switch (black 2P) to the connectors of the

control box. (The control box’s connectors

for the drain pump and the float switch are

also red and blace respectively.) Note that

the control’s connector for the float switch

is already connected to the inside unit’s con-

nector for the float switch, so disconnect

them and connect it to the drain up kit’s con-

nector for the float switch and fix it with the wire clamp.

4) Use hard PVC general purpose pipes VP-25 sold on the market

for drain pipes after draining up.

5) Tighten the PVC pipe securely with the attached clamp after

inserting it in the drain socket.

6) The drain pipe must have downward inclination gradient of 1/

100 or more, and take care not to make a trap or uphill pass.

7) When connecting the drain pipe, take care not to apply force on

the pipe of the unit, and clamp the pipe as close as possible to

the unit.

8) Don’t attach air purge pipe, because the drain might spout.

9) Be sure to provide heat insulation to the indoor side drain pipe.
