1.0 Introduction
These high quality extractor fans are designed to provide effective
ventilation. To achieve this, please read these instructions carefully BEFORE
installing the fan unit. Failure to comply with these instructions could
reduce both the life and performance of the product and may invalidate the
warranty.
This product is suitable for use with a maximum of 1.5m of rigid ducting.
(Flexible ducting is not recommended).
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of
the appliance in a safe way and understand the hazards involved. Cleaning and
user maintenance should not be made by children without supervision.
2.0 Installation
The installation must be completed by competent persons in accordance with
good industry practice and should conform to all governing and statutory bodies
i.e. IEE, CIBSE, HVCA etc.
Before commencing any work read the following instructions carefully and
ensure you have the necessary competency to complete the work safely.
3.0 Dimensions
Isolation - Before commencing work, make sure that the unit,
switched live and any controls are electrically isolated from the mains
supply. If in doubt, consult an electrician.
IMPORTANT
1. Select a suitable position for the fan that keeps the duct as short and as
straight as possible (ideally on the ceiling or on a wall within 400mm of the
ceiling).
2. Cut a hole in the wall to suit the outside diameter of the ducting or wall-liner.
Install the duct or wall-liner taking care to seal at both ends between it and
the wall using proprietary waterproof mastic.
3. Remove the front cover of the fan by pulling the fan back plate straight off
(Fig. 1).
4. Position the fan in the duct and mark the four retaining screw positions
through the backplate. Fit screw anchors suitable for the wall construction.
5. Remove the central terminal cover by first removing the central Posidriv®
retaining screw (Fig. 2).
6. Unclip and remove the fan wall-mounting plate (Fig. 3).
7. Complete the wiring by following the relevant wiring diagram on the
following page (for cable entry detail see Fig. 4).
8. Reassemble using these instructions in reverse.

5.0 Operation
Overrun timer adjustment – models fitted with overrun timers only
Before making any adjustments, isolate the fan from the power supply. Remove
the front cover and the body moulding. Locate the ‘jumper’ on the relevant set
of pins to achieve the desired run-on time (see Fig. 10).
Humidity adjustment – models fitted with humidistat only
All NA-E humidistat fans automatically sense a rapid change in humidity and
adjust accordingly. The humidity control does not require manual adjustment.
Humidistat fans, when energised for the first time, will run and time out as part
of the stabilising process.
6.0 Maintenance
The fan unit does not require any maintenance. However, for optimum
performance, it is advisable to remove any accumulated dust with a low power
vacuum cleaner.
Note: Installation and maintenance of the equipment must be as directed in
the instructions provided with the unit.
