Inline Extraction Fan Kits - 150mm Std Profi le
1. First select the grille you prefer in your room. There are two designs a circular ceiling grille, which we recommend as the interior grille, and a
fi xed louvre grille which is more suited for the exterior.
2. The
interior grille
comes in two parts, the chassis (or spigot) and the circular fascia. If using the gib-fi xing clips option, cut a 165mm hole in
the ceiling directly over the shower head ensuring fi rst that the area above is free from obstruction and between two joists. If not using the gib
fi xing clips option, cut a 155mm diameter hole.
3. If using the gib fi xing clip option the white fastening wedge-type clips must be fi tted onto the grille body – the closed end of the ‘V’ points
towards the rear of the grille. Start the screw through the fl ange on the grille into the screw-hole in the clip with two or three turns.
If the ceiling or wall lining is thicker than standard 12mm board it may be necessary to use longer screws than those supplied. When fi tted,
fasten the ducting onto the grilles using the tape supplied.
Push the grille fully into the hole and then use a screwdriver to push the clips up into the hole. Once through the hole the clips will spring open
and can then be tightened with the screw to pull back down onto the rear side of the lining. Tighten until fi rm only. Do not over-tighten.
Fit the chosen fascia onto the chassis. Note if using the round option, there are two lugs on the rear rim of the insert which locate into
corresponding slots in the black housing, adjacent to the ends of the bridge-piece in the housing.
4. Select a suitable place for the fan to be screwed to a joist and secure using two screws through the fi xing bracket. The fan motor is of ball
bearing design to prolong the life of the motor.
NOTE: The discharge end of the fan unit is the end where you can see the fan blade clearly. There is also an arrow on the unit
showing
airfl ow direction.
5. For the
exterior grille
there is also a choice of options, either a weatherproof cowl or a fi xed grille. Select a suitable position in either the soffi t
or on an outside wall for your chosen grille. Carefully remove the grille insert/cowl from its housing by levering gently at the sides with a small
screwdriver. Cut a 160mm hole ensuring fi rst that the area above is free from obstruction.
6. Attach one end of the fl exible duct to the spigot with the duct tape provided and, from the outside, feed the duct through the hole until the grille
is fl ush with the soffi t/wall.
Mark the position of the fi xing holes on the soffi t/wall. Drill the holes and screw the grille to the soffi t/wall then refi t the chosen grille to the
chassis.
NOTE: It is best not to cut the fl exible duct until the grille has been screwed to the outside surface to avoid the possibility of
cutting the duct too short.
7. Pull the fl exible duct gently to the discharge spigot of the fan and cut it to length and connect to the fan with duct tape provided.
NOTE: The discharge end of the fan unit is the end where you can see the fan blade clearly. There is also an arrow on the unit
showing
airfl ow direction.
8. Connect the remaining piece of duct to the ceiling grille and onto the fan using the duct tape provided.
NOTE: Make sure wherever possible to keep the duct running in a straight line as this will improve the performance of the fan.
