18.1 GENERAL INFORMATION
18.1.1 Specific features
Ideal for the installation conditions characteristic of larger rooms and L-shaped or other non-standard-shaped rooms, the Multi-Type V
series allows an extensive degree of flexibility in the selection of indoor units. Specifically, the selection of indoor units with differing
capacities and differing or similar types is supported, as is the selection of indoor units with similar capacities and differing types.
Furthermore, a maximum of up to four individual indoor units can be operated in synchrony with a single outdoor unit.
(1) Simaltaneous operation possible in non-standard-shaped rooms or large-sized areas.
(2) Select indoor units of differing capacities and differing or similar types; alternatively, indoor units of similar capacities and differ-
ing types.
(3) Up to four individual indoor units can be connected to single outdoor unit.
(4) Indoor unit.
(i) Ceiling recessed type (FDT)
(a) All air supply ports have auto swing louvers. The indoor fan motor has two speeds of high and low.
(b) All models have service valves protruding from the outdoor unit for faster flare connection work in the field.
(c) Low sound level
Operating noise has been remarkably reduced due to adoption of the crescent turbo fan which cuts off wind-blowing
noise and also console type of cabinet which is highly effective to protect vibration.
(d) 700mm high drain head
Adoption of drain pump with high drain head and high capacity (600cc/min) has made it possible to have maximum
700 mm(from below ceiling drain head.[In case 700mm drain head is required, set it up close to the unit. It is impossible
to do piping on down slope.]
(ii) Cassetteria type (FDR)
(a) Quiet sound design
(i) Noise reducing effect has been improved significantly with the employment of large silent steam fans which are
free from the wind swishing sound, and the special designing of noise shielding and acoustic suction panel.
(ii) Ideal adaptation to the need for quiet sound at conference rooms, offices, etc.
(b) 2 types of optional decorative panel
(i) Optional decorative panel consists of silent panel and a canvas duct panel. [has smaller sizes and is prepared with
canvas duct panel which provides higher drain head.]
(ii) Flexibility of installation is increased with 2 type panels.
(c) External static pressure
High external static pressure type (Refer to the specification in clause 2 for the external static pressure.)

(c) Calculation of total operation characteristics
Since the operation characteristics of series Multi depend on combination of indoor unit, calculate the total operation charac-
teristics of the system by using the formulas below according to specifications of each indoor unit or outdoor unit.
1)Total power input
Total power input (kW) = Power input of outdoor unit + ∑(Power input of indoor unit)
2)Total running current
Total running current (A) = Running current of outdoor unit + [∑(Running current of indoor unit) ×2/3]
3)Total power factor
Total power factor (%) = [Total power input (W) / √— 3 ×Total running current (A) ×Power source] ×100
Total operation characteristics = Operation characteristic value of outdoor unit + Operation characteristic value of indoor unit
[Example]
(3) Operation chart
The Multi series is a system that allows for different models and capacities of indoor units to be combined so the individual
operating characteristics of the indoor and outdoor are provided. Use the procedure shown in Item (c) to calculate the combined
operating characteristics.

In the illustration the L is main piping and ra,rb,rc, andrd are branch piping.
(1) When the capacity of the indoor unit to be connected is 208 or less, be sure to use a pipe diameter of ø9.52 for the
size of the liquid piping of branch piping (between branch and indoor units). (for twin, triple, and double-twin
only) For connections to indoor units (liquid piping side dia. ø6.35) use the different diameter adapter coupling
that is included in the branch piping kit.
(2) For the branch be sure to select the specified branch pipe set (sold separately) and then to follow the directions of
the instruction manual included in the branch pipe set when installing the piping. Be sure to install the branch
piping so that the branch is level.
