Thank you for selecting one of our Pro Series mixed ow in-line fan kits.
Please read all instructions before commencing installation.
1. The interior grille comes in two parts, the chassis (or spigot) and the fascia.
The best way to extract steam from the bathrooom is to locate the grill in the
ceiling centred above the shower/bath area. For general bathroom extraction
the grill can be installed centred in the room. Cut hole in ceiling for grill
(See Fig 1. for hole sizing).
If using the gib xing clip option the white fastening wedge-type clips must be
tted onto the grille body – the closed end of the ‘V’ points towards the rear of
the grille. Start the screw through the 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 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
gib. Tighten until rm only, do not over-tighten.
Fit the fascia onto the chassis. Note there are two lugs on the rear rim of the
egg-crate insert which locate into corresponding slots in the black housing,
adjacent to the ends of the bridge-piece in the housing. This ensures the egg-
crate pattern is lined up with the bridge-piece correctly.
2. Select a suitable place for the fan to be installed in the ceiling cavity centrally in
the ducted system. It is recommended to suspend your MixFlo fan from the
ceiling framing with strapping (DCT2299) or fan mounting brackets (FAN0015)
to minimise sound levels resonating through ceiling framing (Fig. 6).
3. For the exterior grille there are two options, either a weatherproof cowl or a
xed grille. Select a suitable position either in the sof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 hole as per Fig. 1.

INSTALLATION INSTRUCTIONS PRO-SERIES
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 airow direction.
• Excessive ducting and sharp bends lower the fans performance.
Before cutting, assure ducting is long enough with gradual bends.

4. Attach one end of the exible duct to the spigot of the inside grill with the duct tape
provided. Pull ducting to fan, cut, and tape.
Attach remaining ducting to the discharge side of the fan and feed other end through
exterior grill hole. Leave ducting long enough to tape spigot of outside grill.
Cut off excess ducting and tape to grill. Push grill in to place and fasten to wall/soft.
To make the electrical connections:
Loosen the 4 screws (K) and take off the connection cover (M) (Fig. 2).
Cut the electrical supply gromet (D) to allow the power supply wires to pass through.
Make the appropriate electrical connections as indicated in Figs. 3, 4 or 5:
• If you wish to install a switch to choose between high speed (HS) and
low speed (LS), see the wiring diagram in (Fig. 3).
• If you wish the fan to work only at low speed (LS), see the wiring diagram
in (Fig. 4).
• If you wish the fan to work at high speed (HS), see the wiring diagram in (Fig. 5).
ELECTRICAL CONNECTION
• The extractor fan must be connected to a single-phase mains network, with the
voltage and frequency indicated on the fan specication plate.
• The installation must have a switch with a distance between contacts equal to or
over 3mm.
• Earthing is not required as this fan has double insulation. (Class II).
• If the fan model you have purchased is not tted with a supply cord then please
note that is must be wired with a xed permanent connection.
