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.)
