Accessory
Caution
●
Be sure to read this manual before installation to follow the proper installation methods.
●
When installing the indoor unit, read the installation manual of indoor unit.
●
Optional distribution parts are required for the piping (Branch pipe set, header set). For details, refer to the catalog, etc.
●
Make sure to install the earth leakage breaker. (Select a product compatible with high frequency.)
●
There is risk of damaging the compressor if the unit is operated while the discharge pipe thermistor, suction pipe thermistor, pressure sensor, etc. are removed. Never attempt to
operation in such condition.
●
With this air-conditioning system, room temperature may rise, depending on installation conditions, while indoor units are stopped, because small quantity of refrigerant flows into
the stopped indoor units if heating operation is conducted on the system.

●
Do not use any refrigerant other than R410A. R410A will rise to pressure about 1.6 times higher than that of a conventional refrigerant.
●
A unit designed for R410A has adopted a different size outdoor unit service valve charge port and a different size check joint provided in the unit to
prevent the charging of a wrong refrigerant by mistake. The processed dimension of the flared part of a refrigerant pipe and a flare nut's parallel side
measurement have also been altered to raise strength against pressure. Accordingly, you are required to arrange dedicated R410A tools listed in the
table on the right before installing or servicing this unit.
●
Do not use a charge cylinder. The use of a charge cylinder will cause the refrigerant composition to change, which results in performance degradation.
●
In charging refrigerant, always take it out from a cylinder in the liquid phase.
●
All indoor units must be models designed exclusively for R410A. Please check connectable indoor unit models in a catalog, etc.
(A wrong indoor unit, if connected into the system, will impair proper system operation)

Refrigerant pipe distribution parts, which are not contained in the package, will be required for installation.
As for refrigerant pipe distribution parts, we offer branching pipe sets (Model type: DIS) and header sets (Model type: HEAD) as parts used on the indoor side of piping.
Please select one suiting your application. In selecting distribution parts, please also refer to “4. REFRIGERANT PIPING.”
If you are not sure which parts to select, please consult with your dealer or the manufacture.
When washing existing pipes using the re-fresh kit, it is necessary to install the service valve kit (Model: FDCR-V-KIT-E).

2. INSTALLATION LOCATION
(Obtain approval from the customer when selecting the installation area.)
2-1. Selecting the installation location
①
Place the unit outlet pipe perpendicular
to the wind direction.
②
Please install so the direction of the air from the blowing
outlet will be perpendicular to the direction of the wind.
③
When the foundation is not level, use wires
to tie down the unit.
〇
Where air is not trapped.
〇
Where the installation fittings can be firmly installed.
〇
Where any object does not prevent inlet or outlet air.
〇
Out of the heat range of other heat sources.
〇
Where strong winds will not blow against the outlet air.
〇
A place where stringent regulation of electric noises is applicable.
〇
Where it is safe for the drain water to be discharged.
〇
Where noise and hot air will not bother neighboring residents.
〇
Where snow will not accumulate.
〇
A place where no TV set or radio receiver is placed within 5m.
(If electrical interference is caused, seek a place less likely to cause the problem)
Please note
a) If there is a possibility of a short-circuit, then install a flex flow adapter.
b) When installing multiple units, provide sufficient intake space so that a short-circuit does not occur.
c) In areas where there is snowfall, install the unit in a frame or under a snow hood to prevent snow from accumulating on it.
(Inhibition of collective drain discharge in a snowy country)
d) Do not install the equipment in areas where there is a danger for potential explosive atmosphere.
e) Install the equipment in a location that can sufficiently support the weight of the equipment.
f)
If a unit is installed into a special environment as shown below, there will be a danger that the corrosion of the outdoor unit or its
malfunctioning is caused. If this is the case, please consult with the distributor from whom you have purchased the unit.
・
Where corrosive gas is generated (such as a hot-spring resort area).
・
Where the unit is subject to sea breezes (coastal area).
・
Where the unit is subject to oil mists.
・
Where equipment generating electromagnetic waves exists in the vicinity.
g) When strong winds occur
●
Where it is likely that the unit is subjected to strong winds, provide wind guards according to the following guidelines.
Strong winds can cause performance degradation, an accidental stop due to a rise of high pressure and a broken fan.
CAUTION
Please leave sufficient clearance
around the unit without fail.
Otherwise, a risk of compressor
and/or electric component failure
may arise.
When installing units side
by side, install the flex
flow adaptor. (This is not
required if a distance of
1,500 mm may be
secured between the
blowing outlet and the
wall.)
