Wiring Wiring should be done as stipulated in the electrical drawing in the door of the motor's

terminal box (Fig. 7).

BESB250-4-1, BESB315-4-1

All one-phase ventilators are voltage regulated. The motor is fitted with a thermal cut-out. The thermal-cut out is factory installed and wired in series to the motor's power circuit (electrical diagram in the terminal box fig. 1). Use the circuit diagram (Fig. 2) if a manual reset is required after a thermal cut-out, where the thermal cut-out is used as a contact in the control circuit. The motor has overload protection.

BESB500-4-3 The ventilator has a three-phase motor, which cannot be voltage regulated.

NB The motor does not have a thermal cut-out and should have a correctly rated

circuit breaker installed.

The motor can be regulated using an installed external frequency converter max. 50 Hz.

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.
