10.1 GENERAL INFORMATION
10.1.1 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 cabtyre cable with 4 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 service valves protruding from the outdoor unit for faster flare connection work in the field.
(5)
The position of the suction port can be changed.
The suction from the lower inlet is available by replacing the duct connecting section (at the side face) and the lower plate. (They
are changed on site.)

408, 508 :[φ19.05(3/4″)]: Equivalent piping length = Real piping length + (0.15 × Number of bends in piping)
[Equivalent piping length < Limitation length of piping + 5m]

When the outdoor unit is located at a lower height than the indoor unit in cooling operation the following values should be
subtracted from the values in the above table.

Note (1) Values in the table indicate the one way piping length between
the indoor and outdoor units.
How to obtain the cooling capacity
Example : The net cooling capacity of the model FDUR308CEN-A with the air flow “High”, the piping length of 15m, the outdoor unit
located 5m lower than the indoor unit, indoor wet-bulb temperature at 19.0 ˚C and outdoor dry-bulb temperature 35 ˚C is

10.4 OUTLINE OF OPERATION CONTROL BY MICROCOMPUTER
Except for function relating to heating, same at the unit for FDUR heat pump type. See page 306.
10.5 APPLICATION DATA
The application data for the cooling only models are similar to those for the heat pump models. (See page 322.)
10.6 MAINTENANCE DATA
This is same as FDUR heat pump series. Refer to page 340.
