Opus OK / Genie NKF1
Kitchen Extract Unit
Fig. 1. General view of a surface mounted unit.
Introduction
Nuaire's Opus/Genie Kitchen extract fan is designed to be
installed in the area to be ventilated. The unit may be surface
mounted or semi recessed using the optional mounting
flange kit.
Inlet is through two filters located on the front cover of the
unit. which can be easily removed for cleaning. (Filters and
front cover plus fixings are supplied bagged separately and
are fitted during installation).
Exhaust air is discharged through a 100mm dia. spigot on the
rear of the unit.
The Opus/Genie Kitchen unit has two speeds; 'Low', 'Boost'
and an 'Off' position. Manual operation is by a pull cord.
'Low' and 'Boost' speeds can be selected by successive pulls,
a third pull returns the unit to the 'Off' position.
The unit extracts 74 l/s on full speed and 35 l/s on low speed.
A single (full) speed model without pull-cord for remote
operation via a light switch or similar (not supplied) is avail-
able. See Coding on page 4.
A two speed unit is available for remote operation via a two
speed, on/off switch (supplied).
An optional humidity control may be specified. When sup-
plied with this option the unit continuously monitors the
relative humidity (RH) within the kitchen. The humidistat
sensor is located within the unit case, behind the front cover.
The point at which the fans operate can be adjusted to suit
the individual installation. At any time the unit can be man-
ually over-ridden so that the 'Low' and 'High'
settings may be selected independently of the Humidity
control. See 'Humidistat Installation & Adjustment' page 3.
When triggered, the RH sensor operates the fan on 'Boost'
until the RH returns to below its set point. Control then
reverts to the manual position chosen previously. The two
speeds are visually indicated by twin LED's on the front
panel.
A unit with an integral humidistat override is available. The
units speeds are selected by a bell push switch (supplied).
