Hitachi's AquaFREE system is a Heat Pump heating system for winter, and a partial cooling system for summer. The system consists of an Inverter Heat Pump outdoor unit and a hydraulic

module indoor unit. The heat pump absorbs or sends the heat to the outside, and transfers it to the water circuit by means of the AquaFREE module.

The AquaFREE air conditioning system incorporates a set of

technical benefits that make it one of the most attractive on the market. Right from selection of the ideal type of equipment in each case, up to its maintenance, and through installation, start up and operation. AquaFREE always provides the best solution for every user and greatly simplifies and eases the user's selection process.

AquaFREE systems provide great comfort, high reliability, rigorous design, low electrical consumption and require less installation space than a conventional boiler.

NOTES:

The nominal cooling and heating capacity is the combined

capacity of HITACHI'S AquaFree system, and it based with

the following standards:

Cooling capacity EN 12055

Heating capacity reverse cycle units EN 255

The Sound Pressure Level is based on the following conditions: 1 meter from unit's front surface Voltage of the power source is 230V

The above data was measured in an anaechoic chamber so that reflected sound should be taken into consideration when installing the unit.
