SECTION 4 – COMPONENT REPLACEMENT
4.1. LIGHT REPLACEMENT
1.
Disconnect the mains supply.
2.
Pull the lamp away from the hood by gripping the edge of the bezel.
3.
When the spring becomes exposed, push it back against the lamp body to allow it to come through the
hole in the hood.
4.
Unclip the terminal block from the failed lamp and clip the new one in place (the one supplied with
the replacement is surplus to requirements).
5.
Twist the bezel to release it and re-fit to the new lamp.
6.
Fold up the springs against the body of the lamp and slot back through the hole in the hood.
4.2. MOTOR REPLACEMENT
1.
Isolate the power supply at the fan speed controller or the distribution board.
2.
Remove the baffle filters necessary to access the motor. This is achieved by sliding the filter up a
short distance (no more than 20mm) and swinging out from the base.
3.
Either one or two of the filter infills will need to be removed. The necessary infills are screwed in (the
remainder are riveted and not intended to be removed). If the infill appears down the centre of the
motor, check the upper and lower edges for the fixing screws and remove with a T15 Torx driver. If
two infills overlap the motor at each end, these will be removable by the same procedure.
4.
Disconnect the motor supply connection (see page 5).
5.
Mark each motor support bracket screw mounting hole, for future reference when re-mounting the
motor.
6.
Remove the two self-tapping screws holding the motor to each support bracket and carefully
withdraw the motor from the SmartVent.
7.
Fit the motor by reversal of the above procedure ensuring the motor is relocated correctly inside the
exhaust flange.
