Effect of subcooler

Refrigerating ability increased bysupercooling circuit

DC Compressor

By using DC, the performance is improved at around 30 - 40Hz wherethe operation time of the inverter compressor is longest. Also, to suppresselectromagnetic noise interference and achieve low noise, the rotor hasbeen divided into two and the electric pole displaced.

High COP

Performance is greatly improved by

the high-efficiency, high pressure,

inverter driven scroll compressor.

Reliability greatly improved byoptimised bearing

Intake loss and leakage losslargely reduced by asymmetricscroll lap

Heat loss largely reduced by oilreturn structure

Accurate oiling to the compressor

by improved oiling system

New design air panel

The air panel was revised to give a fresh and simple design.Prevention of smudging and short-circuiting is also takeninto account.

Extremely Quite Operation

Uses a blade design resulting in an exceptionally quiet fan.HI-stream fan achieves the lowest level of noise, 28 dB (A)(RCI-1.0FSN1E).

Compact, low height units

The height of the units is just 298mm so they can easily be installedin a small space. The units require limited ceiling space which enablesimproved work efficiency in installation behind the ceiling.

High ceiling adaptability satisfies a wide variety of requirements

This model is adaptable to a high ceiling with a height of 4.2m by usingspeed-up taps. These features allow comfortable air conditioning in highstreet stores.

NOTES

For setting 3 and 2 directions, the separately sold 3-way outlet parts set is necessary.

Speed up (1) and Speed-up (2) can be selected through RCS by using C5 option.

Wireless controller (option)

See page 43.

Fresh air intake

Connection of fresh air intake can be taken in by connecting the ductbeside indoor unit. The control duct fan will operate only when unit isoperating giving good air recirculation and comfort.

Branch duct

Available across the range for added flexibility

DC Fan Motor with Outstanding Efficiency

The DC fan motor greatly improves efficiency compared with conventionalproducts having an AC motor. Also, air blasts are reduced by controllingthe rotation speed of the fan.

Drain-up mechanism is equipped as standard.

Anti-mould filter is equipped as standard.

Quiet operation, easy installation and space saving design

Versatile mounting

To expand installation and positioning options, HITACHI hasadded a second drain pipe connector, one more than conventionalunits. Refrigeration pipes have also been improved and can now beconnected at the left, right or rear of the unit.

Space saving design Hitachis unique feature

An innovative fan and heat exchanger design led to the creation oftodays ultra-slim ceiling unit. Fully adjustable mounting brackets permitclose fitting to the ceiling to make installation possible in even the smallestarea. Less than 163mm of vertical space are required for installation.

Quiet Operation

The ceiling unit is equipped with a highly efficient, multi-bladecentrifugal fan that generates a powerful yet gentle airflow throughoutthe room. A redesigned aerodynamically tested air panel minimisesoperational sound even at high fan speeds.
