Timer Fans
Timer fans are designed to be connected to the lighting circuit so that they
will operate when the light is switched on, and stay on for a pre-set time
after the light has been switched off.
Timer and Humidistat Fans
Timer and Humidistat fans are designed to be connected to the lighting
circuit and will operate when either the light is switched on or when the
humidity level exceeds the pre-set level between 60 and 90%.
Once the light is switched off, or the humidity level drops below the pre-
set level, the fan will stay on for the time period set by the timer control,
between 2 -30 minutes.
Noise Level
All ventilations fans have a low noise level, under 35dB.
Thermal Fuse
All ventilation fans have a thermal fuse which prevents the motor
overheating if the impeller becomes jams.
Installation Instructions
Ventilation Fan Performance
1. Switch off the mains supply before commencing the installation.
2. Drill a hole in the wall to suit the fan and ducting:
4” fan Ø 110mm hole max.
6” fan Ø 155mm hole max.
If mounting the fan on the ceiling, position the fan between the joists
3. Route ducting from the fan position to the external grille position,
ensuring the end of the ducting is flush to the walls. Ducting runs
should be as short as possible for optimum performance.
4. Remove the front cover of the fan by undoing the securing screw on
the bottom edge.
5. Hold the body of the fan in position and mark on the wall/ceiling the
four fixing screw positions and the cable entry hole.
6. Drill and plug the wall/ceiling.
7. Route the cable so that it exits through the wall ceiling at the position
marked, leaving enough cable protruding so it can be terminated.
8. Fix the fan body in position.
9. Terminate the cable.
10. Fit the front cover and tighten the securing screw.
Shower Fan Kits
The ventilation fan in the shower fan kit should go in-line with the ducting,
between the internal and external grilles, and should be positioned in the
loft space. Secure the ducting to the fan and grilles using the cables
supplied.
Deta ventilation fans are design to meet the requirements of The Building
Regulations –Approved Document F1 Means of Ventilation, and The
Building Standards (Scotland) –Domestic Ventilation.
These Building Regulations and the Domestic Building Services Compliance
Guide state the intermittent extract ventilation fans should have a specific
fan power (SPF) less than 0.5W/(ltr/sec). Deta fans meet this requirement.
Fan Positioning
Deta’s ventilation fans are designed to move air over short distances,
typically under 2m, and are suitable for through wall installations. These
ventilation fans can also be installed in ceilings with the ducting length
under 2m.
The ventilation fan should always be sited in the wall or located on the
ceiling furthest from the main source of air replacement, e.g. door, to
ensure optimum performance. The fan should also be located as high as
possible.

Installation Instructions for
Extractor Fans
Wiring
Standard Fans
The standard fan can be connected to the lighting circuit and controlled
from a switch so that it only operates when the switch is on. The fan must
be fed by a DP switched connection unit fitted with a 3A fuse. See Fig. 1.
The connections for this fan are:
L permanent live
N neutral
Timer Fans and Timer and Humidistat Fans
The timer fan can be connected to the lighting circuit. The circuit for this
fan must be protected by a 3A device and should be controlled by a 3 pole
fan isolator. See Fig. 2.
The connections for this fan are:
L permanent live
S switch live
N neutral
Low Voltage Fans
The Low Voltage ventilation fan can be installed in zone 1 in a bathroom or
shower room, however the supply transformer must be installed outside
zone 2 (see Special Installations or Locations Particular Requirements in
the current edition of the IEE Wiring Regulations, BS 7671). The
transformer requires a 240V supply, and has an ELV output to the fan.
Shower Fan Kits
In-line fans in the shower fan kit are mains voltage and wiring is identical
to timer fan, see Fig. 2. The 12V light in the shower kit is low voltage and is
fed by the voltage transformer which is wired independently from the
ceiling rose/junction box.
Control Adjustments
The timer and humidistat and timer fans are supplied with an insulated
screwdriver for adjusting the controls, which is clipped to the fan body.
Timer
The timer is adjustable from approximately 2 minutes to 30 minutes. The
timer is factory set at approximately 15 minutes. Turn the control
clockwise to increase the on time. Timers should be set for 15 minutes
minimum.
Humidistat
The humidistat range is approximately 60 –90% relative humidity. The
humidistat is factory set at approximately 75%. Turn the control clockwise
to increase humidity
