PRIMARY LARGE SINGLE SPLIT INVERTER SERIES

General Features

Features, advantages and benefits

PRIMAIRY includes all required for selection, installation and maintenance, making it the perfect choice for small businesses and workplaces, as well as other interior spaces. When in use, PRIMAIRY responds sensitively to air temperature and maintains it at the desired level, using just the right amount of energy.

RELIABILITY

How to know when a product is truly safe? When it is hardly ever necessary to check it. Each key area requiring a failsafe feature has been thoroughly researched and a dependable solution incorporated. Where possible, Hitachi air-conditioning units are self-diagnosing when it comes to errors. Physical protection is combined with sensors for a system of smooth operation and security.

SAFETY PROTECTION
An encompassing metal box design ensures full product safety.

DISCHARGE TEMPERTURE SENSOR
Ensures the compressor will operate in the safety range, and prevent the damage caused by refrigerant leakage.

LOW/HIGH PRESSURE SWITCH
High pressure and Low pressure switches keep the system and compressor reliable.

TEMPERATURE PROTECTION SYSTEM

• Fan motor overheating protection
• Compressor overheating protection
• Compressor starts preheating in cold climate

RELIABLE RUNNING
Oil viscosity testing was taken for compressor in order to ensure reliable operation.

ERROR SELF-DIAGNOSIS FUNCTION
The error code is clearly displayed on the diagnostic panel of the outdoor unit for quick troubleshooting and maintenance.

OUTDOOR UNIT ERROR CODE DISPLAY
(with outdoor control box)
There are two ways an error is displayed: in digits or via a flashing indicator light on an outdoor control board. Based on the digits or the amount of times the light flashes, various faults are represented.

REFRIGERANT LEAKAGE DETECTION
The indoor unit will stop operation automatically and show an error code when the refrigerant charging amount is lower than 30%, which can avoid the compressor being damaged by high temperature due to refrigerant leakage. When the refrigerant charging amount is between 30%~80%, the unit will judge itself if showing an error code is necessary. This feature can also better ensure the heat transfer efficiency and the safety of the unit.

HYDROPHILIC ALUMINUM FIN
A hydrophilic aluminum fin enhances heat exchanging performance by increasing water mobility on fin surface and preventing water droplets from forming blockage between fins. The blue coating enhances protection from corrosion resulting from environmental and microbiological factors, increasing reliability and ensuring performance.

WIDE AMBIENT TEMPERATURE RANGE
High cooling and heating performance within a wide ambient temperature range. If your business requires cooling all year long (technical rooms, server rooms) you can trust PRIMAIRY, as cooling can operate from -15ªC to +48ºC. Focus on your business and PRIMAIRY will take care.

MORE FLEXIBLE PIPING
Both short and long piping may be applicable to the installation needs of different sites. The right placement of the indoor unit is key to distributing the air properly.

Long piping and large height difference
Up to 50m in piping run and 30m in height can be covered, with great overall flexibility in installation.

INDOOR UNIT INPUTS & OUTPUTS
Built in inputs and outputs at the indoor unit enable connection to external systems as key slot or other device.

EASY INSTALLATION

EASIER HANDLING OUTDOOR UNITS
As with every other important variable in setting up your PRIMAIRY system, there are multiple alternatives available for the outdoor unit. Each one is modular and straightforward to fix into place. We will assist you in each key phase of installation as you set up your system.

COMPACTNESS AND LIGHTNESS
Free of unnecessary or weighty components, each unit can be carefully slid into place by the installation team.

CASSETTE INDOOR

Cassette units are especially suited to narrow ceiling cavities or high ceilings. They fit to a standard ceiling grid and can be easily incorporated between light panels and other overhead fixtures.

Homogeneous air flow with 4-Way louvers
Homogeneous distribution airflow is available with 4 way louvers for an excellent comfort at every corner of the room.
Vertical and horizontal swing are available for air redistribution in all directions.

Temperature compensation
Cassette bring temperature compensation setting by wired controller. This function can revise this temperature difference to make a more accurate temperature control.

DESIGN FLEXIBILITY
Infrared Receiver for Remote Controller
Reserved port for Remote sensing which makes control more convenient.

EASY MAINTENANCE
Washable Filter
A washable filter allows for cost-saving maintenance.

DUCTED

The efficient design makes the Ducted unit especially discreet. Ducted units can be installed in multiple points to thoroughly aerate each part of a space.

COMFORT

Durable Protection Drainage System
The special design of the drain pan makes condensation water flow smoothly without water leakage, and prevents rust.
When the drain pipe is clogged and the water rises to a certain level, the water level switch will float and send the signal to turn off the unit.

Built-in drain pan
Compared with outside drain pan design, the new builtin drain pan can reduce dust adhesion, and avoid water leakage.
