1.5 Connecting to duct system:

Flexible connections
Sound pressure level
The ventilator must always be connected to the duct system with FLF, to avoid any chance of vibrations being transmitted. The spigots on the ventilator are standard-sized and fitted with rubber seals.
To achieve maximum performance with minimal energy consumption the ventilator should be connected to the duct system with the specified lengths of duct before and after the ventilator. The FLF connections must always be fitted as shown.
The ventilator is fitted with sound dampers suited to the requirements of the operating area. The sound pressure for all types of BESB is less than 70 dB (A). The duct system is insulated against sound propagation, heat loss, fire and condensation.
No Duct A protective net (accessory) with mesh size of 12 mm must be fitted if the ventilator is
not fitted to a duct. It should be noted that:
such fittings result in a pressure drop in the system
Air volume measurements cannot be measured correctly when there is no duct fitted on the suction side

1.7 Service and cleaning

EXHAUSTO provides a two-year factory warranty on the box ventilator, valid from invoice date. The motor in an EXHAUSTO box ventilator is fitted with special ball bearings that are lubricated and sealed, and maintenance-free. Any replacement of these bearings should be carried out by technicians from EXHAUSTO SERVICE or similarly qualified professionals.
The ventilator must be cleaned at least once a year. To clean the ventilator:
• Switch off the power supply to the ventilator using the repair circuit breaker. Open the service door when the fan has stopped running.
• Wash the ventilator housing and the centrifugal impeller thoroughly with soap and water. The parts must be dry and the service door closed before the ventilator is restarted.
• The centrifugal impeller can be dismounted and cleaned. Measure the exact position of the impeller on the axle before removing it. The factory position of the impeller is shown on the cabinet behind the service door. If there are weights on the centrifugal impeller do not remove them.
• Check that cooling air can move freely through the motor cover.
Spare parts Ventilator components that can be ordered as spare parts are marked with position
numbers. When ordering spare parts supply the ventilator type and the production order number (PO); both can be read on the information plate.
