15.1 GENERAL INFORMATION
15.1.1 Specific features
(1)
Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been
reduced by more than 50%.
(2)
The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit.
There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic
noise thus the incidence of microcomputer malfunction has been reduced. The compressor in the outdoor unit has its own self
protection function, that reacts according to abnormal high pressure and excessive high temperature.
(3)
There are only five power lines between the outdoor and indoor unit, As no signal wire is used there is no need to separate the
power line from the signal line. One cab tyre cable with 6 wires encased in one sheath is enough for conducting the wiring work
between the outdoor unit and the indoor unit. This contributes to simpler wiring work in the field.
(4)
All models have control valves protruding from the outdoor unit for faster flare connection work in the field.
(5)
Operation noise has been drastically reduced by increasing the number of high performance fans and by through sound insulation.
(6)
When installing, the optimum outside static pressure can be set using the fan controller.
(7)
With the height of all equipment made uniform at 360mm and neatly installed into the ceiling, the installation of equipment with
different capacities into the same ceiling space is made easy.

Note (1) Equivalent piping length can be obtained by calculating as follows.
308 series [φ15.88(5/8″)]: Equivalent piping length = Real piping length + (0.10 × Number or bends in piping)
408, 508 series [φ19.05(3/4″)]: Equivalent piping length = Real piping length + (0.15 × Number of bends in piping)
808 series [φ25.4(1″)]: Equivalent piping length = Real piping length + (0.15 × Number of bends in piping)
1008 series [φ28.58(1 1/8″)]: Equivalent piping length = Real piping length + (0.20 × Number of bends in piping)
[Equivalent piping length < Limitation length of piping + 5m]

15.2.7 Characteristics of fan
How to interpret the blower characteristics table
Example ¡What is the Fan Controller’s Volume Number setting if, at the high operation speed of FDU308-A (60Hz), it is required to
have 140Pa (14mmAq) outside static pressure at 24m3/min airflow volume as the operation point?
Move the 140Pa (14mmAq) outside static pressure point to the right as shown in the diagram below. The “ a -point”, i.e.
where this intersects with the solid curve tracing the 24m3/min airflow volume upwards, is the appropriate Volume Number.
In this example the appropriate Volume Number is “No. 6”.
¡In this situation, a condition of 19.7m3/min airflow volume at 93Pa (9.3mmAq) outside static pressure can be predicated at
Low Tap and it can be concluded that operation is possible.
Always follow the procedure in “ b -point” to verify that the condition at Low Tap is not outside the Feasible Operation
Airflow Volume Range.
Notes (1) Circled values in the Special Feature Table indicate Fan Controller Volume Numbers. Volume Numbers with no entry are
outside the Feasible Operation Airflow Volume Range and therefore operation is not possible.
(2) The Fan Controller Volume Number is set at “No.5” when shipped from the assembly plant.

15.5 APPLICATION DATA
SAFETY PRECAUTIONS
• Please read these “Safety Precautions” first then accurately execute the installation work.
• 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
• This system should be applied to places of 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 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.
• 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 (R22) 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.

In order not to transmit vibration from the main unit of air conditioner to the ceiling or slab, it is necessary to provide means to prevent
vibration, for example, a canvas coupling on the duct or rubber cushion on the main unit of air conditioner.
A damper to control air volume should be installed on the joint of OA duct to facilitate control of air capacity after the installation.
Location and from of blow outlet should be selected so that air from the outlet will be distributed all over the room, and equipped with
a device to control air volume.
Make sure to provide an inspection hole on the ceiling. It is indispensable to service electric equipment, motor, functional components
and cleaning of heat exchanger.
Make sure to insulate the duct to prevent dewing on it.
Thickness of insulating material is 65 mm minimum.

1 If a duct is not provided at the suction side but it is substituted with the
space over the ceiling, humidity in the space will increase by the influ2
ence of capacity of ventilation fan, strength of wind blowing against the
outdoor air louver, weather (rainy day) and others.
1
a) Moisture in air is likely to condense over the external plates of the
unit and to drip on the ceiling.
Louver to
Unit should be operated under the conditions as listed in the above
outdoor air
table and within the limitation of wind volume.
When the building is a concrete structure, especially immediately
For ventilation
after the construction, humidity tends to rise even if the space over
the ceiling is not substituted in place of a duct.
In such occasion, it is necessary to insulate the entire unit with glass wool (25 mm).
(Use a wire net or equivalent to hold the glass wool in place.)
b) It may run out the allowable limit of unit operation (Example: When outdoor air temperature is 35°CDB, suction air temperature is
27°CWB) and it could result in such troubles as compressor overload, etc.
c) There is a possibility that the blow air volume may exceed the allowable range of operation due to the capacity of ventilation fan or
strength of wind blowing against external air louver so that drainage from the heat exchanger may fail to reach the drain pan but leak
outside (e.g. drip onto the ceiling) with consequential water leakage in the room.
2 Unless vibration isolation is provided between the unit and duct and between the unit and the slab, vibration will be transmitted to the
duct so that vibration noise may generate from between the ceiling and blow outlet or vibration may be transmitted to the slab. Make
sure to provide an effective vibration prevention means.
Bad example of duct work
<Simplified method for determination of duct dimensions>
<Table of simplified selection

(d) 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 this purpose.
(e) Be sure to provide heat insulation to hard PVC pipes of indoor placement.
(f) Do not ever provide an air vent.
(g) Avoid postitioning 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.
<Provision of trap>
Since the drain outlet is disposed at a position
that makes the pressure negative, it is necessary to provide a trap (during the piping work)
in order to prevent water leakage due to rising
of water level in the drain pan.
Trap must be so constructed to facilitate cleaning. It should be better to employ a "T" joint
as shown below. In addition, the height of trap
should be as specified below. The trap should
be provided close to the unit.
If the duct is connected and then the blower is operated,
inside air pressure will become negative compared with
the atmospheric pressure.
