Technical Description; Mounting The Roof Vent - Dometic GY 11 Mode D'emploi

Technical description

5 Technical description
The roof vent with motor GY11 is for ventilating the interiors of caravans, mo-
torhomes and boats. It can also be used in toilets, kitchens, above gas and
paraffin lamps and in shower rooms. The cover cap is weatherproof.
The vent is motorised. The blades of the vent wheel are directed towards the
side. They therefore do not obstruct the air flow when the vent is off.
The vent is controlled by a switch with three settings (fig. 4 1, page 5):
 Setting 1: Fan speed 1, half power (max. 65 m
 Intermediate setting: Fan switched off
 Setting 2: Fan speed 2, maximum power (max. 105 m

Mounting the roof vent

Note on installation location
 The vent should be mounted on the roof on a level surface. When mount-
ed on a sloping surface, the roof hood must be rotated so that one of the
three water drainage holes is directed toward the incline. A tilt angle up to
20° will not affect the performance of the vent when the motor is not run-
ning.
 The vent removes air from the interior. Make sure there is an adequate air
supply! The air intake opening must be at least 60 cm
Mounting the vent
➤ Select an appropriate installation location for the vent on the roof.
➤ Provide an opening for a three-step switch (not included in scope of deliv-
ery), for example at the kitchen unit.
➤ Draw the location and size of the opening of 105 mm diameter for the vent
(fig. 2, page 3) and for the opening of the switch.
➤ Pre-drill and cut out the holes on the roof carefully with a keyhole saw or
similar tool.
➤ Place the vent (fig. 3 3, page 4) on the opening (fig. 3 5, page 4) and
mark the six screw holes.
➤ Apply a thin ring of a permanently elastic sealing material around each
hole.
