Safety precautions of indoor unit
Please read these "Safety Precautions" firstly when performing the installation work.
Though the precautionary points indicated herein are divided under two headings, 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 section. However, there is also a possibility of serious consequences
in relationship to the points listed in the 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.
CAUTION
WARNING
WARNING
This system should be applied to places as office, restaurant, residence and the like. Application to inferior environment 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.
When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for
the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this
countermeasure, consult with the company from which you perchased the equipment, and make the installation accordingly.
In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur, there is the danger of a
resultant oxygen deficiency accident.
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury
can result from a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes,
etc. Improper installations can result in accidents due to a violent falling over 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 installation 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.
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its 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
(R407C) 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.
CAUTION
Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground
wire. 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 event 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.

Pour water into a convex joint.
When constructing drain piping for several units, position the
common pipe about 100 mm below the drain outlet of each unit
as shown in the sketch. Use VP-30(11/4") or thicker pipe for this
purpose.
Be sure to provide heat insulation to hard PVC pipes of indoor
placement.
Do not ever provide an air vent.
The height of the drain head can be elevated up to a point 500
mm above the ceiling, and when an obstacle exists in the ceiling
space, elevate the piping to avoid the obstacle using an elbow
or corresponding gadget. When doing this, if the stretch for the
needed height is higher than 500 mm, the back-flow quantity of
drain at the event of interruption of the operation gets too much
and it may cause overflow at the drain pan. Therefore, make the
height of the drain pipe within the distance given in the sketch
below.
Avoid positioning the drain piping outlet at a place where generation
of odor may be stimulated. Do not lead the drain piping direct
into a sewer from where sulfur gas may generate.
Drainage
Conduct a drainage test after completion of the electrical work.
During the trial, make sure that drain flows properly through the piping and that no water leaks from
connections.
In case of a new building, conduct the test before it is furnished with the ceiling.
Be sure to conduct this test even when the unit is installed in the heating season.
Procedures
Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.
Check the drain while cooling operation.

Drainage Test
Conduct a drainage test after completion of the electrical work.
During the trial, make sure that drain flows properly through the piping and that
no water leaks from connections.
In case of a new building, conduct the test before it is furnished with the ceiling.
Be sure to conduct this test even when the unit is installed in the heating season.
Procedures
Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.
Check the drain while cooling operation.

When constructing drain piping for several units,
position the common pipe about 100 mm below
the drain outlet of each unit as shown in the sketch.
Use VP-30(11/4") or thicker pipe for this purpose.
(d)
(e) The stiff PVC pipe put indoor side should be heat insulated.
(f) Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain
hose directly into drainage, where the gas with sulfur may be generated.
Backwater bend
Because the drain spout is at the position, which negative pressure may occur. So with the rise of
water level in the drain pan, water leakage may occur. In order to prevent water leakage, we designed a
backwater bend.
The structure of backwater bend should be able to be cleaned. As the below figure shown, use T
type joint. The backwater bend is set near the air conditioner.
As figure shown, set a backwater bend in the middle of drain hose.

8. The attentive matters in installation of air suction and discharging duct
Recommend to use anti-frost and sound-absorbing
duct. (locally bought)
The duct installation work should be finished before the
fitment of ceiling.
The duct must be heat insulated.
The specific air-discharging outlet should be installed at
the place where the airflow can be reasonably distributed.
The surface should leave a checking meatus for checking
and maintenance.
9. The examples of improper installation
Do not use air in duct and take the ceiling inner side instead. The result is because of the irregular
outer air mass, strong wind and sunshine, the humidity is increased.
There may be water drop on the outside of duct. For cement and other new constructions, even if not
taking ceiling inner side as duct, the humidity will also be so high. At this time, use glass fiber
to perform heat preservation to the whole. (use iron net to bind the glass fiber)
Affected by the capacity of air discharging fan, the strong wind in the outer duct and wind direction,
when unit air sending volume exceeds the limit, the discharged water of heat exchanger will overflow,
leading to water leakage.
Air Air

Special air discharging outlet
Use screw bolt to fix
Maybe exceeding the unit operation limit (for example: when indoor dry bulb temperature is 35degree,
web bulb temperature is 24degree), it may lead to overload of compressor.

10. The operation method of fan controller
Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted.
It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment).
The air volume set should be in the operation air volume range.
Figure I shows the position of fan controller in the electric box and operation method.
After finishing the electric work, perform test run. According to the main points in Figure II making the chosen
switch No. accordant. And confirm if it reaches the needed air volume.
Note:
1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the
power supply.
2) Do not set the dial at the position less than 1.
3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity
number may exceed the permitted operation capacity range, so it is impossible to operate.
4) When delivering from factory, the capacity number of fan controller is set at No.5.
Rotate this switch
(capacity number
setting:
No. 1 ~ No. 8)
Once the fan controller
has trouble, this linker
can perform emergency
assistant control. When
this linker is connected
to the linker from the
PCB, it can operate with
total load.
When this linker is
connected to the linker
from the PCB, through

5. Electric wiring
(1) Selection of size of power supply and interconnecting wires.
Precautions for Electric wiring
Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round type
crimped terminal lugs with insulated grip on the ends of the wires.
Use copper conductor only.
Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with less
than 2% voltage drop.)
When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown,
use spanner and torque spanner together.
When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use
hand to twist 3-4 rings, then fasten with spanner.
Referring to Table I to confirm the fasten torque. (too tight may damage nut leading to leakage)
Check if the connection pipe leaks, then do heat insulation treatment, as below figure shown.
Only use seal cushion to bind the joint part of air pipe and heat insulation parts.

Please read these "Safety Precautions" first then accurately execute the installation work.
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.
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 of this equipment, based on the owner's manual.
Moreover, ask the customer to keep this sheet together with the owner's manual.
WARNING
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.
Please install your air conditioner on a wall or any place which can holder the weight of the
air conditioner. And it cannot be installed on a non-professional metal structure (such as a
burglary-resisting net). Otherwise injury would occur due to a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong airs
of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent
falling over of the unit.
Wiring shall be done with the specified cable and the connection shall be firm and reliable.
And the terminal connector shall be fixed firmly and reliably not to let external force exercise
on the cables. Any improper connection or fixing would cause heat, fire, and other accidents.
Wiring shall be done in a correct shape not to make any section rise upward, and accurately
install the air conditioner. The cable shall not be clamped by the lid or outer plate. Any
improper installation would lead to fire, heat, or other accidents.
When setting up or moving the location of the air conditioner, do not mix air etc, or anything
other than the designated refrigerant (R407C) within the refrigeration cycle, for such mixing
would result in rupture and injury caused by abnormal high pressure.
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.
The drain pipe must not be placed or connected into the sewage tank where harmful gas such
as sulphurous gas and etc would exist, otherwise the harmful gas would enter the room.
During installation, if the refrigerant is leaked, please immediately take measures of
ventilation, otherwise a harmful gas would be generated whenever the refrigerant meets fire.
After installation, please ensure that the refrigerant is not leaked, because the leakage of
refrigerant would produce a harmful gas if it meets fire or heating stoves.
Don't install the air conditioner where a flammable gas would be probably produced,
otherwise in case the flammable gas is leaked and exists around the unit, fire would be
caused.
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.
The refrigerant gas pipe and liquid pipe shall all be thermally insulated to preserve the
temperature. Any improper insulation would make the unit moist and the water would drop
onto the floor or wet the indoor items.

3˅Outdoor defrosting temp. sensor: when ambient temp. is below -5ć, detect after having start for 3
minutes.
7.2.9.12 Backup operation
Outdoor TC failure treatment: outdoor LED alarms, but the failure code will not be sent to other place,
the outdoor default TC is as follow: cooling temperature, 5ć; heating temperature, 40ć.
7.2.9.13 Special functions
1) Power operation
When receiving the Power operation signal from indoor, the unit will operate as the set
frequency by EEPROM. Fan speed will depend on the ambient temperature and the frequency.
When the Power signal is cancelled by indoor, the Power operation will stop.
2) Soft operation
When receiving the Soft operation signal from indoor, the unit will operate as the set frequency
by EEPROM. Fan speed will depend on the ambient temperature and the frequency. When the Soft
signal is cancelled by indoor, the Soft operation will stop.
3) Time shorting operation
When receiving the time shorting signal, the unit will perform the 1/60 time shorting operation.
4) Compulsory cooling operation
When receiving the compulsory cooling signal from indoor unit, the unit will execute the
compulsory cooling operation at the frequency sent from indoor. Only discharging temperature
protection and current protection are valid, all the other protections are invalid.
5) Oxygen bar: start after receive indoor oxygen bar signal, the outdoor motor should run at 1-class
speed when compressor stop.
6) Manual defrosting
When receiving the manual defrosting signal from indoor, the unit will enter the defrosting
operation immediately. The interval between two manual defrosts is at least 3 minutes. If the
communication protoco has not the set, this function is not available.
7) Rated, Middle, Minimal operation
When receiving the rated/middle/minimal operation signal from indoor, the unit will operate at
the frequency and fan speed set by EEPROM, meanwhile, all the protections are valid.
7.2.9.14 Outdoor indicator
Five-indicator combination shows the failure code.
4-bit dip switch: the normal position is ON.
First bit: OFF, compulsory cooling.
Second bit: OFF, compulsory heating.
Third bit: OFF, backup operation (outdoor ambient temp.).
Fourth bit: OFF, DC fan motor (ON, AC fan motor).
