Unit description
BREVA EX
is a heat pump outdoor unit that can be coupled to
indoor units of the same series for the air-conditioning of small/
middle-sized rooms. Designed for outdoor installation, it is suitable for
use in residential and small business premises.
The rotary-type compressor is controlled via DC-Inverter control with
continuous modulation from 20% to 110%, thus ensuring high energy
standards. The fan DC motor improves performance and sound comfort.
The expansion valve electronically optimises the flow of refrigerant within
the circuit (excluding BREVA EX 9000-1).
The R32 refrigerant allows high yields, thus placing
BREVA EX
the most efficient devices on the market.
1.4
Safety and adjustment devices
The device safety and setting are achieved thanks to
- compressor motor thermal protection, which is triggered incase
the current consumed by the compressor is excessive
- gas delivery temperature sensor, which transmits the detected
value to the electronic board that is triggered in case of
over-temperature (116°C)
- anti-freeze sensor, which transmits the temperature value as
detected by the heat exchanger to the electronic board that is
triggered when the heat exchanger is clogged by frost formations
- suction temperature sensor, which transmits the detected value
to the electronic board that is triggered in order to adjust the flow
of refrigerant gas or to stop the unit in case of overtemperature
(40°C)
- outdoor air temperature sensor, which transmits the detected
value to the electronic board that is triggered in order to adjust
the operation of the unit indoor components to the variation of
weather conditions
Safety device replacement must be carried out by
Technical
Support Service, using only original components. Please refer to the
spare parts catalogue.
IT IS FORBIDDEN to operate the device with faulty safety systems.
1.5
Identification
The unit can be identified through the technical data plate:
Technical data plate
Contains the device's technical and performance data.
The tampering, removal, or absence of the identification plates will
not allow the product to be properly identified by its serial number.
