4.
Remove the PCB cover by removing 2 off No6 x
1
⁄
2
inch screws.
Fig 14. Removal of PCB cover from casing.
5.
Partially remove the PCB assembly from the fan casing by
placing a finger tip behind the dip switches and pulling the PCB
away from the fan casing. (see fig 14).
6.
Disconnect and remove the fan scroll from assembly and
completely remove the PCB assembly. Note: if the pull cord is
not required, remove it completely.
7.
Prepare an opening 205mm x 185mm in the mounting position.
8.
Position the mounting bracket in the previously prepared
aperture so that the ends of the bracket are flush with the
surface of the wall. Secure the bracket top and bottom with
suitable fixings (by others).
9.
Drill and plug (if necessary) the mounting surface.
10. Feed wiring flex through the back of the fan casing and
mounting plate.
11. Secure the case to the surface (fixings supplied by others). Note:
care must be taken not to twist or distort the case whilst fitting.
12. Partually replace PCB into the fan casing and wire flex into the
terminal block (see wiring options on page 5).
13. Replace fan scroll assembly and plug motor into PCB, replace
PCB fully into position by pushing the dip switches.
14. Replace PCB cover by fitting with 2 off No6 x
1
⁄
2
inch screws.
(see point 2 of the procedure).
15. Fit semi-recessed mounting flange to case using 4 off No4 x
3
⁄
8
inch screws.
16. Fit front inlet grille using 4 off No6 x
3
⁄
4
inch screws found in
the fixing kit.
17. Remove rubber gasket and adjust control to required settings
(shown in section 4). Once required settings are complete and
desired airflow rate is achieved replace rubber gasket.
18. Complete the fan installation by fitting (push fit) the front cover.
Fig 15. Ceiling mounting using the Semi-Recessed mounting kit.
First cut an aperture for the fan in the ceiling, cut and fit (A) timber
supports (not supplied) and fit fan as shown. Note: Remove the
shutters from the spigot if you are mounting CYFAN in the ceiling.
Note: pull-cord must be removed.
