FIGURE 2. KNOCKING OUT THE 100 mm SPIGOTS
7. POSITIONING & PREPARATION
7.1 POSITIONING
7.1.1 The unit is best installed wall mounted in a kitchen above a cooker hood, but if this is
not practicable, it can positioned in the loft or any suitable location.
7.1.2 It is not advisable to install the unit so that it is directly above a bedroom or living room
ceiling, or in an area that is part of a living area or bedroom. If this is likely to cause a
problem, please contact Johnson and Starley Ltd.
7.1.3 Consideration must be given to access for servicing, as servicing of the fans and
cleaning of the heat exchanger, which should be carried out annually.
7.2
REMOTE SPEED CONTROL POSITION
7.2.1 The speed control is a remotely fitted control which can be fitted in a position of your
choosing. The control is suitable for a single 32 mm deep back gang box which can
be surface mounted. The front plate assembly can be fitted to an existing back box if
required.
7.2.2 Remove the 2 screws securing the front plate assembly, and retain.
7.2.3 Follow the fitting instruction for the remote speed control.
7.3
PREPARATION OF SPIGOTS
7.3.1 The unit is supplied with 100 / 125 mm spigots and for satisfactory operation on the
unit where the airflow rate is above 33 l/s (see performance curves on page 14), it is
recommended that the centre part of the spigot is removed and 125 mm ducting used.
7.3.2 The centre part of the spigot can easily be removed by placing a flat piece of wood (or
similar) over the centre part and applying a sharp tap with a hammer (see Figure 2).
NOTE:
In situations where it is either not possible or not desirable to use 125 mm ducting, 100
mm ducting can be used but it MUST be noted, in “BOOST” mode might increase noise
levels.
7.4
