The systems offer flexibility in project design, with increased COP and EER, and can operate in outdoor temperatures as low as -20°C.

Indoor and Outdoor Units
Hitachi's indoor units come in various configurations, including floor-concealed, floor-standing, wall-mounted, and ceiling types. The outdoor units are designed for easy installation and maintenance, with flexible piping connections and high static pressure capabilities.

Control Systems and Optional Parts
Advanced control systems optimize air conditioning environments, offering improved demand control and power consumption management. Optional parts and accessories enhance system functionality and customization.

Installation and Maintenance
The RPIM units are designed for easy installation in limited spaces, with accessible electrical and piping connections. Maintenance is simplified with easy access to key components and a new air filter design. The units are engineered for noise reduction and efficient operation in various settings.

Technical Specifications
The document outlines specifications for a range of air conditioning units, highlighting their flexibility and adaptability for various installation conditions. Units support static pressure up to 150 Pa and are designed for extended ducting, providing full temperature control even in remote areas. They feature adjustable airflow and fan speed control.

Product Range
The lineup includes models from 0.8HP to 6.0HP, with a built-in drain-up mechanism that activates automatically. Units come with a suction filter as standard and offer options for return air entry.

Design and Features
Units feature a slim design, adjustable fan speed, and static pressure. They include a drain pump and air filter as standard. The Econofresh Kit can provide up to 100% fresh air and 'free cooling' when outdoor temperatures are favorable.

General Data
Models vary in cooling and heating capacities, airflow rates, and sound pressure levels. They use R410A refrigerant and feature flare nut connections for refrigerant piping.

Installation and Maintenance
The RCIM series offers easy installation and maintenance with a compact design suitable for small spaces. Units are equipped with a DC fan motor for improved efficiency and reduced noise. The design includes high ceiling adaptability and a drain-up mechanism with a high pump lift.

Additional Features
The RCI series includes a new air panel design for improved aesthetics and functionality. Units are designed for quiet operation and feature a slim air panel and standard drain pump. The RCD series offers a compact turbo fan for noise reduction and easy maintenance with auto-louvers.

General Specifications
The document provides technical specifications for outdoor units in the Set Free FSN1(E) and FXN series, designed for cooling and heating operations with power supplies of AC 3Ø, 380-415V, 3~ 50Hz or AC 3Ø, 400V, 50Hz. Nominal cooling capacities range from 14.0 kW to 118.0 kW, while heating capacities range from 16.0 kW to 132.0 kW. EER and COP are provided for each model, indicating efficiency.

Sound Pressure Levels
Sound pressure levels are measured at 1 meter from the unit and 1.5 meters from the floor, with variations in cooling and heating modes. Night mode reduces noise levels by 5 dB(A). Measurements were taken in an anechoic chamber, suggesting real-world installations should consider reflected sound.

Physical Dimensions and Weight
Dimensions and weights vary across models, with heights generally at 1,745 mm and widths ranging from 630 mm to 3,390 mm. Net weights range from 160 kg to 970 kg.

Refrigerant and Piping
All units use R410A refrigerant with microprocessor-controlled expansion valves. Refrigerant piping connections are factory supplied, with specific dimensions for liquid and gas lines.

Control Systems
The H-Link Transmission System allows for flexible design and easy installation, enabling central control through the CS-NET web system. This system supports remote monitoring and control of up to 128 indoor units and 16 outdoor units via Ethernet.

Changeover Boxes
New Changeover boxes are compatible with FXN Set Free Heat Recovery systems, reducing piping connections and installation time. They offer flexible electrical box positioning for easier servicing.

Remote Control and Monitoring
CS-NET web provides remote control and monitoring capabilities, with features like user and installer access levels, a four-year timer, and historical data storage for maintenance purposes. The system supports integration with LON WORKS® BMS systems through the HARC-BX gateway interface.

Additional Features
Remote controllers like the PSC-5S and PC-P2HTE offer centralized control and scheduling capabilities for large installations, supporting up to 256 units.

Control Systems

PSC-5T 7-Day Timer: Allows for long-term unattended control with weekly scheduling options. It supports two types of weekly schedules (A and B) and displays settings digitally for easy operation.
PC-LH3A Wireless Remote Control Switch: Offers simple one-touch operation for controlling multiple units without wiring. A receiver kit is required for certain models.
PC-P5H1 Simplified Remote Control Switch: Smaller and easy to use, primarily for temperature adjustment. Suitable for hotels, restaurants, and offices, it can control up to 16 indoor units and displays alarm codes.

Optional Parts and Compatibility
The document lists various receiver kits and remote control options compatible with different types of indoor units, including cassette, wall, floor, and ceiling types.
