• To enable the synchronous operation function, then (after prior completion of the pairing procedure) push the button on the remote controller of the
MASTER appliance.
• Synchronous operation is indicated with the “
” symbol displayed on the screens of both the MASTER and SLAVE appliances. Example screen below:
• To enable synchronous operation of the SLAVE appliance, its B1 slider must be set to ON.
• If the MASTER appliance operates with the recuperation option, then the SLAVE appliance will display its actual operating direction.
• Synchronisation is possible in all operating modes of the MASTER appliance (recuperation, air supply, air exhaust, timer, higro, night).
• If any function on the remote controller of the SLAVE appliance (e.g. speed or operating mode) is used during synchronous operation) synchronisation with
that appliance will be interrupted. To return to synchronous operation, push the button on the remote controller of the SLAVE appliance or complete
synchronisation, namely turn off and on the synchronisation in the MASTER appliance.
• If SLAVE appliances are turned off, when the synchronisation is activated, they will be turned on automatically.
• Turning on/off the appliances with the button will not interrupt synchronisation,
- for the MASTER appliance, it turns off/on all paired appliances.
- for the SLAVE appliance, it turns off/on only the SLAVE appliance.
Note:
Synchronisation will be interrupted if the MASTER appliance is turned off, when the SLAVE appliance is turned on.
First start-up
Start the appliance only with all safety precautions in place and all hazards eliminated. Start the appliance. Check that it runs steadily and the air is handled
efficiently.
Check the operation of the fan (noise, vibration, power consumption, the possibility to control the rotation speed).
The appliance may be used only with front panels (internal and external) that prevent touching the moving parts. The user is liable for compliance with current
safety standards and may be held liable for accidental injury or death caused by failure to provide the required safety.
Electrical connections
• Electrical connections and commissioning of the air exhaust fan shall only be completed by qualified professional electricians.
• Always follow the applicable standards, safety regulations and technical requirements specified by the power company!
• The power supply line for the air exhaust fan requires a multi-pole circuit breaker / isolation switch with a minimum contact break gap of 3 mm (ref. PN-EN
60335-1)!
• The mains system, voltage and frequency must match the nameplate ratings.
Dimensions
The dimensions are shown in Figure 5 and 6.
MAINTENANCE AND CLEANING
Electrocution hazard by damaged wiring insulation!
Lock out and tag out the appliance before any maintenance works!
Servicing and maintenance
• Use protective footwear and gloves during maintenance!
• During all maintenance and servicing works the electrical and OHS regulations (PN-IEC 60364-3) must be observed.
• Before servicing the fan, isolate it from the mains voltage with the circuit breaker. Secure the circuit breaker against inadvertent operation!
• The fan ductwork must be clear of foreign bodies: hazard of injury by objects blown out at a high speed!
• Do not attempt any maintenance when the fan is running or at live voltage!
• If excessive vibrations are felt or heard, have the technical inspection carried out by a qualified electrician.
• The maintenance intervals depend on the actual contamination of the rotor and filter, they must not be longer than 6 months!
• Check the rotor for cracks.
• The manufacturer shall not be liable for any damage resulting from unprofessional repairs.
• The appliance is equipped with motors that have been lubricated for life, the motor is maintenance-free.
Cleaning
• Clean the front panels (external and internal) and visible parts of the housing with a damp cloth.
• Do not use aggressive paint solvents!
• Do not clean with a high pressure cleaner or strong jets of water!
• Clean carefully to prevent water from entering the motor or the terminal box.
• The grid at the inlet/outlet of the fan must be kept clean at all times.
• Clean the filters and the exchanger when the message appears on display of the appliance or every 6 months (the message is displayed for a few seconds after
the appliance is turned on).
•
Periodical air filters and exchanger cleaning procedure:
Loosen the locking screws, then remove the internal front panel.
- Disconnect the motor and temperature sensor connectors, then slide out the exchanger/motor block.
- Remove the filters from the appliance and then rinse under running water.
- Clean the accessible components of the exchanger/motor block with a vacuum cleaner or compressed air.
- After drying, insert the air filters.
- Slide the exchanger/motor block into the ventilation duct and then connect the motor and temperature sensor connectors.
- Place and then screw the external front panel.
- Reset the air filters operation time counter.
