Cabinet
is made of durable high density EPP. The front metal panel is powder coated white. The Ø 93 mm connection circular sockets are fitted on the top and bottom of the cabinet with the possibility of turning them to the sides of the unit. The throats are fitted with a double-edged seal. Revision access is from the front of the unit.
Fans
The unit contains two radial fans with forward curved blades with EC motor.
Motors
They are single-phase EC with low power consumption, 230 V / 50 Hz. IP21 protection.
Recuperation
Counter-current heat exchanger with thermal efficiency up to 80%. The humidity transfer is suitable for the Central European climate zone and ranges up to 25%. The exchanger is accessible by opening the front panel.
Filters
The unit is fitted with two G4 class (ISO coarse 65%) plate filters for both the intake and exhaust.
Additional filters:
- AR-W filter set G4/G4
- AR-W1 filter set M5/G4
Electrical connection
A three-core 230 V / 50 Hz power cable is led out of the unit, which is not terminated with a fork (connection to the box).
Regulation
The unit is equipped with a fully automatic control system with flow regulation according to relative humidity. The innovative control system with temperature sensors and humidity sensor ensures fully automatic operation of continuous ventilation without the need for any further intervention in the unit control. A wired controller is included to allow switching from automatic operation to three power speeds. The system indicates filter contamination by an audible signal or LED indication on the connected controller. The frost protection system ensures operation of the unit down to an outdoor temperature of -10 °C without the need for additional preheating or reheating of the air. The unit can be set to operate in automatic or manual mode. The unit is equipped with a contact to activate the BOOST function.
Mounting
The unit is designed for horizontal installation under the ceiling in indoor spaces. The required ambient temperature is between 10 and 50 °C. The unit shall be mounted to provide sufficient space for removal of the unit face, replacement of filters, connection of the condensate drain to the SF-P 138 siphon odour trap and for periodic inspection of the wiring. If the unit is mounted above the soffit, an inspection opening for the operator is required.
Noise
Acoustic pressure is indicated in the table of technical parameters.
Accessories
- AR Flex system components
Instructions
Thanks to the high efficiency of the heat exchanger and the innovative control system, preheating and reheating are not necessary. After basic setup by the installer, the unit requires no further adjustment. Filter replacement is recommended at least once a year. The design of the AR Flex system and its use in buildings with category B gas appliances (gas boilers and open chamber water heaters) or open hearth appliances using solid or liquid fuels with flue gas exhaust to the chimney are subject to the applicable regulations. Ventilation must comply with the normative regulations on fire safety in buildings and must not contravene fire regulations.
Information
