Inline Extraction Fan - 150mm
INSTALLATION
1. Cut a suitable size hole for the grille in the ceiling directly over the
shower head ensuring first that the area above is free from obstruction
and between two joists.
2. Select a suitable place for the fan to be screwed to a joist and secure
using two screws through the fixing bracket.
3. Select a suitable position either in the soffit or on an outside wall and
cut a suitable size hole for the eggcrate grille. Attach one end of the
flexible duct to grille with duct tape and from the outside feed the
ducting through the hole until the grille is flush with the soffit/wall.
Secure the grille to the wall.
NOTE: It is best not to cut the flexible ducting until the grille
has been screwed to the outside surface to avoid the
possibility of cutting the duct too short.
4. Pull the flexible ducting gently to the discharge spigot of the fan and
cut it to length and connect to the fan with duct tape.
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 airflow direction.
5. Connect the other piece of duct to the ceiling grille and onto the fan as before using duct tape.
NOTE: Make sure wherever possible to keep the duct running in a straight line as this will improve the performance of the fan.
6. Make the electrical connection as follows:
Wiring of Standard Switching model FAN0090 (fig.1).
The fan can be connected to the light switch so that the fan will start when the light is switched on, or a dedicated fan switch (not supplied).
The fan should not be accessible to a person using either the shower or the bath.
Wiring of Timer Switching model FAN0091 (fig. 2).
The fan can be connected to the light switch so that the fan will start when the light is switched on, or a dedicated fan switch (not supplied).
The fan should not be accessible to a person using either the shower or the bath.
NOTE: All wiring must be fixed securely and the cable to the fan should be a minimum of 1mm
2
in section in section. All wiring
must comply with current regulations. This system should be installed by a registered electrician.
When the light switch or fan switch is switched off the fan will run for between 20 seconds & 30 minutes (pre-set to 1 minute). This can be
adjusted in Timer Adjustment instructions on page 6. The fan should not be accessible to a person using either the shower or the bath.
NOTE: This unit is double insulated and therefore does not require an earth. Try to keep the duct as straight as possible and
wherever possible keep the distance between the ceiling grille and the external soffit or wall as short as possible as the shorter
the length of duct, the better the performance of the fan.
