Installation for External Grille (EFD01RDWEKIT ONLY)
A suitable position must be found that will suit:
1. The position of the vent on the outside wall.
2. The location of studs, pipes, wires inside the cavity. Make a circular hole
in the outside wall.
From the outside:
1. From the outside, pull the ducting through the outside hole.
2. Remove the inner louvred grille section by gently prying open with a screw
driver.
3. Attach the vent frame to the duct with the cable tie firmly.
4. Push the vent frame back into the hole and attach with the appropriate
screws for the wall material.
5. Snap in the louvred grille from the outside with the louvres pointing
downwards.
Note:
It is desirable to have the ducting as taut as possible as any slackness
may restrict the air-flow through the ducting.
