Surface Mounted ( 'B' range)
Domestic Extract Fans
Installation
and Maintenance
1
Introduction
Nuaire’s OPUS 30 & 60 range of surface mounted domestic
extract fans are designed to be installed in the area to be ventilat-
ed, for example bathrooms and WC compartments, but are
ideally suited for stores, drying rooms, cupboards, etc.
The fans discharge air through 100mm. dia. outlet spigot and
have provision for adding a 50mm dia. subsidiary inlet to extract
air from a second room.
Typical arrangements
Surface mounting, wall or ceiling
One room extraction
Two room extraction
(with side subsidiary).
Two room extraction
(with rear subsidiary).
Semi recessed version
Units are available with one or two fans and in two duty sizes
32 l/s and 61 l/s.
Inlet is through filters located on the front cover of the unit
which can easily be removed for cleaning.
Units can be fitted with a selection of controls which enable
them to be linked to light switches, either directly or through
run-on cicuits.
Coding
BBasic unit with single fan.
BS Single fan unit incorporating a run-on circuit.
2BAS Twin unit incorporating both run-on and fan failure
detection/change over circuits.
BX Single fan unit providing continuous low duty
running with boost when room light is switched on.

IMPORTANT WARNING
Installation and servicing MUST be carried out
by electrically quaIified personnel.
The unit MUST BE TOTALLY ISOLATED from the
electrical supply before removing covers.
NOTE internal input socket will be exposed and
MAY BE LIVE with the fan module removed.
See ‘ISOLATION’ notes.
Fig. 1. General view of unit.
Installation
a) It is assumed that a solid non reverberant mounting posi
tion has been selected, and the necessary passages for duct
work, from outlet spigot and to subsidiary inlet spigot (if a
second room is to be ventilated) as well as the electrical con
nection prepared. It is also assumed that compatible duct
work is already installed.
b) Note that the front cover, fixing screws and filters are
bagged separately. Release the spring clips retaining the fan
module and then withdraw the fan module from the case.
If a second room is to be served, remove the appropriate
weakened area from the case and working from the inside
fit the subsidiary inlet spigot by passing it through the case
and turning quarter of a turn to lock. Fig. 3a and 3b.
Remove the relevant cable entry in the back of casing.
c) Position the case in the mounting position, connect to the
ductwork and feed the supply cable through the cable entry.
Fig. 4.
Secure with three No. 8 woodscrews, drilling and plugging
the mounting surface if necessary. Connect the wiring to
the internal terminal block/socket.
d) Fit the fan module to the case, mating it’s plug fully with
the internal socket. Lock with the spring clips. Fig. 5.
e) Fit the cover and fix using the four screws supplied. Fit the
two filters into the rebates on the front cover.
Test/run the unit.

Maintenance
General
It is inevitable that some dust, fluff etc. will pass through the fil-
ters, and which, if allowed, will build up internally on motors
and impellers, shortening the life of the unit and, in severe cases,
leading to overheating of the motors.
Consequently, it is strongly recommended that all units are
inspected and cleaned every six months. To clean the filters,
remove them from the unit , wash in tepid water to which a lit-
tle mild detergent has been added. Shake out excess water and
allow to dry naturally. Replace when dry.
Isolation
Ensure that the unit is totally isolated from the electrical supply.
This is particularly important when dealing with a run-on cir-
cuit or a continuously running fan unit with boost when the
room light is switched on (letter X in the Model Code) AS THE
INPUT SOCKET TERMINALS WITHIN THESE UNITS
REMAIN LIVE, EVEN WHEN THE ROOM LIGHT OR
OTHER ACTUATING SWITCH IS OFF. Take care therefore
when working within the case with the fan module removed.
Procedure
At all times, take care not to damage, distort or disturb the
balance of the impellers. Remove the cover and then the fan
module after releasing the spring clips. Inspect all parts.
Using a brush or dry cloth clean the backplate. Lightly brush
away dust and dirt from the fan module. If stubborn, carefully
remove with a suitable blade or scraper. Wash the cover in warm
soapy water. Dry thoroughly. Refit the fan module, followed by
the cover. Test/run the unit.
Adjusting the run-on timer
Remove cover. Locate the Time Delay Adjustment at the plastic
box integral with the fan module. Re-set against the graduated
scale. Re-fit the cover.
Warranty
The plastic control box integral with the fan assembly is a sealed
component. Breaking the plastic sealing tie will invalidate the
guarantee. The unit is guaranteed for a period of 3 years.
