1.0 Introduct on
The Nuaire HPKF Kitchen Extract fan is designed to be
mounted on a wall within a kitchen. The unit contains two
fans, one of which runs continuously providing
‘trickle’ ventilation, and a boost speed operation which can
be triggered manually or automatically. Fig 1. shows a
general view of the unit.
The unit will exhaust through the wall (125mm dia. back
outlet) or alternatively through the ad acent ceiling (150mm
dia. top outlet).
A suitable spigot is supplied ready to fit in the users chosen
position following removal of the top knockout or back
aperture cover plate.
A washable metal grease filter is located in a recess on the
underside of the case and can easily be withdrawn for
cleaning.
LOW or HIGH ‘boost’ speed can be initiated manually by the
remote switch provided or automatically via the
integral ad ustable thermostat or via an external trigger
such as ‘Cooker Miser’ (details on request).
Fig 2. The remote control switch.
Remote Control Sw tch
A remote switch is included which allows the user to select
auto or manual operation, and a high or low manual ‘boost’
speed (see fig 2).
NOTE: Caution! The control wiring carries 230V mains
voltage.
Thermostat ( ntegral)
A thermostat control knob is located on the top face of the
unit. The range of ad ustment is 0-60 oC. The chosen
setting will dictate when the unit switches to ‘boost’ speed.
The thermostat only operates in auto mode.
The user can override the thermostat when required by
switching to manual, or can permanently disable the
thermostat by removing the BROWN link wire on the
control wiring panel if desired. (see fig 4).
Sett ng the ‘boost’ speed (auto mode only)
In ‘auto’ mode, the preferred ‘boost’ speed can be set for
LOW (half) or HIGH (full).
Note: in ‘manual’ mode the ‘boost’ speed is fixed HIGH (full)
The wiring connection panel is located under a removable
top mounted cover plate.
The RED link wire can be relocated to change the ‘auto’
mode LOW or HIGH boost setting (see fig 4).
2.0 Installat on
Select and mark out a suitable mounting position. Note the
clearance between the top of the unit and the ceiling must
not be less than 150mm when fitted to allow manual
ad ustment of the top mounted thermostat control and
sufficient room to allow removal of the electrical access
cover.
Select a mounting position for the remote control switch as
close to the unit as is practical.
Refer to dimensions drawing and cut a suitably sized hole
in the wall (125mm dia outlet) or ceiling (150mm dia. outlet)
to allow connection to any associated ductwork (by
others).
Drill and plug the three mounting position holes in the wall
as per fixing deOffer the unit up and screw into position

using appropriate fixings. During the operation, connect
the outlet spigot to the ductwork, if applicable, and feed the
electrical cables through the grommets into the connection
recess.
Wire the supply and the remote switch into the unit
terminal strips (see wiring diagrams fig 4).
Sett ng the thermostat
The thermostat control knob is located on the top face of
the unit. Advance the thermostat control knob through the
ambient room temperature position (you can detect this as
a gentle click around 20oC position). Set the control in
excess of the ‘click’. This will trigger the fan to operate on
boost when the room temperature increases.
When the ambient room temperature increases beyond the
chosen thermostat set point, the unit will automatically
switch to the boost speed -the auto boost speed factory
set at HIGH (full) but can be changed to LOW (half) by
relocating a link on the circuit board. (See wiring in Fig. 4).
Electr cal connect on
The installation must be carried out by a suitably qualified
and competent person and conform to all relevant
regulations.
The electrical supply to the unit must be isolated by a
suitable local double-pole isolating switch (by others) for
maintenance purposes.
Note that the ma ns w r ng for the un t MUST be from a
f xed w r ng nstallat on.
The unit MUST be earthed.
Connect the incoming supply to the mains terminals.
Connect the remote control switch (six wires 0.5mm2500V
ac rated) ensuring connections match at the switch.
Replace cover plate.
Test ng after nstallat on
Manual operat on
Set the remote switch to MANUAL and HIGH.
Check the unit is functioning satisfactorily by switching on
the mains supply.
The unit should start and run on the HIGH (full speed)
Select LOW speed and check for LOW (half speed) operation.
Switch off the mains supply.
Automat c operat on
Select AUTO on the remote switch. In this mode the unit is
controlled by the integral thermostat. See ‘Setting the
thermostat’
The fan will run continuously providing a ‘trickle
ventilation’.
Reducing the thermostat control setting temporarily will
trigger the fan for test purposes.
The fan should switch to the boost speed.
Reset the thermostat as detailed in previous paragraphs.

Installat on and Ma ntenance HPKF High Performance Kitchen Fan

3.0 Ma ntenance
The unit is sealed and has no user serviceable parts inside.
No lubrication is required as the unit motors have sealed
for life bearings. Occasionally wipe the unit over with a
damp cloth.
4.0 F lter Clean ng
The metal grease filter must be kept clean as otherwise the
unit performance will be greatly reduced. Cleaning should be
carried out approximately every 6 weeks but this may be
varied depending on the frequency of use.
To clean the filter, first switch off the fan. Remove the two
screws under the front lip, drop the filter down from the
back slot, shake out any loose dust then immerse the filter
in hot water containing ordinary household detergent (do
not add soda to the water under any circumstances).
Agitate occasionally to help free the grease. Wipe clean,
remove from the water and allow to drip dry. Return the
filter to the unit.
5.0 Replacement of Parts
Should any component need replacing Nuaire keep extensive
stocks for quick delivery. Ensure that the unit is electrically
isolated, before carrying out any work.
