Awenta WD [10/32] Maintenance and cleaning
ATTENTION! A rotating impeller can crush your ngers! It is forbidden to start the fan
without a protective mesh against touching the moving parts!
First start
Start the fan only with all safety precautions in place and all hazards eliminated. Start the fan. Check that it runs
steadily and the air is handled eciently (out of the room and through the air exhaust ductwork to the outside).
Check the operation of the fan (noise, vibration, the possibility to control the rotation speed).
The fan may be used only with ventilation ducts that protect against contact with moving parts. If the fan is
installed with ducts shorter than 1.5 m, an additional protective grid is required.
Note that the fan 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 equipment.
Electrical connections
• Electrical connections and commissioning of the fan shall only be completed by qualied professional
electricians.
• Always follow the applicable standards, safety regulations and technical requirements specied by the power
company!
• The power supply line for the 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 of the fan.
Dimensions
The dimensions of specic fan models are shown in Fig. 3.
MAINTENANCE AND CLEANING
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 qualied electrician.
•
The maintenance intervals depend on the actual contamination of the fan rotor and must not be longer than
6 months!
•
Check the fan rotor for cracks.
•
The manufacturer shall not be liable for any damage resulting from unprofessional repairs.
Cleaning
Electrocution hazard by damaged wiring insulation!
Before attempting to clean the fan, isolate it from the mains voltage with the circuit
breaker. Secure the circuit breaker against inadvertent operation!
•
Clean the front panel and the 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 of the fan ducts must be kept clean at all times.
