Page 2: Cleaning Options
1. Cleaning options Self-cleaning effect Under the usual conditions for the operation of ventilation systems and air conditioning systems, rotary heat exchangers do not tend to become contaminated. This is due to the laminar airflow in the rotor mass and the counter-current circuitry.
Page 3: Cleaning Device
2. Cleaning device If strongly adhesive contamination is present in the air, the installation of an automatic cleaning apparatus may be sensible. Usually, blowing out with compressed air is sufficient. Cleaning with high-pressure warm water is necessary only with tenacious viscous and greasy contamination. Please note that the residual water is to be blown out of the rotor following cleaning.

Page 5 On reaching the centre sensor, the air relay switches off and the carriage travels to the starting position. During the cleaning procedure, the rotor runs with variable speed under the control of the AS2 control system. The external control signal (0 - 10 Volt) is not processed during the cleaning procedure, so this process should...

Page 11: Functional Description
Functional description The cleaning control system enables the automatic, electronic cleaning of the contaminated thermal mass of a rotary heat exchanger. Standby indicates readiness for operation. A start signal from an external contact, the start button or an optional time switch activates the cleaning procedure. Following the start command, the carriage travels without media to the centre of the rotor.
Page 12 Scope of delivery The standard version of the cleaning device includes the following: Control box for AS 2 cleaning control system, degree of protection IP 54 (dimensions: see dimension sheet: page 25 Cleaning mechanism for compressed air cleaning Standard guide rail with covering on the inlet side Carriage with corresponding nozzle supports Pneumatic nozzle, including hose connections ca.

Page 14: Connection And Commissioning
3.4 Connection and commissioning The mechanical components (rail, carriage, motor, supports, and sensors) are pre-mounted and must be attached to the frame with screws. The frame is also prepared with rivet-down nuts. Adjust the pneumatic nozzles and, if necessary, the high-pressure nozzles so that these end around 20 - 30 mm before the thermal mass.
Page 15 Start the cleaning procedure with the Start button. The cleaning carriage must continuously drive towards the centre of the rotor. If this is not the case, stop cleaning and reverse the direction of rotation of the motor by switching two phases of the motor. When the direction of travel is correct (after changing the direction of rotation, restart the cleaning control), the carriage drives to the centre of the sensor and then begins the actual cleaning process.

5. Menu navigation The operational readiness of the AS2 is indicated by: S t a n d b y P a r k i n g p o s i t i o n To access the menu hold down the Stop button ( ) and press the Reset and the Enter buttons ( Attention: The cleaning procedure can be stopped and then started again with these buttons.

Runtime: R u n t i m e p e r R u n t i m e c l o c k T a k t i m p u l s 1 , 5 In this menu item, you can set the travel time for the cleaning carriage. The nozzles should advance by a maximum of 10 mm per clock pulse.
Page 20 Tolerance limit: T o l e r a n c e l i m i t T o l e r a n c e l i m i t s : 1 0 % Here, a safety margin is set in % (5, 10 and 20%) for the steps / cycles counted in the learning trip. This is used to compensate for mechanical gear tolerances and to balance out heat technology-related situations (hot / cold).
Page 21 This menu item can be used to improve drying, by allowing the cleaning slide to advance only at every 2nd, 3rd or 4th turn of the rotor. This removes as much remaining water from the accumulation as possible. Caution: Cleaning will take longer with this function. Tresholds: T r e s h o l d s H / R...
