Green Brook 12VFC, 12VFCPC, 12VFCT, 12VFCTPC, 12VFCHS Installation & Operating Instructions Manual

IIMMPPOORRTTAANNTT
Please note, this safety extra low voltage (SELV) fan and its supply
controller must be installed by a fully qualified electrician in compliance
with current I.E.E and appropriate local regulations. In order to satisfy
current building regulations, correct fan selection and installation
practices must be applied.

PPOOSSIITTIIOONNIINNGG TTHHEE CCOONNTTRROOLLLLEERR

It is a requirement of I.E.E. regulations that the controller is installed in a
position that is out of reach of a person using a bath or shower. Controller
models which do not have a humidistat may be fitted outside the room
containing the fan.
Humidistat models must be fitted inside the room containing the fan and

sited as high on the wall as possible, but not within 50mm of the ceiling
and adjacent wall. All controller models must not be installed in a shower
cubicle, above a bath or where there is any possibility of liquid spray. They

must not be installed where the normal air temperature may exceed 40°C
or in an area containing excessive levels of grease.
Fan controllers should not be covered with any heat insulating material, air

flow around the fitting should not be restricted. Note 50mm minimum
distance to all adjacent surfaces. All models come complete with a patress

box but can be flush wall mounted by using a suitable 25mm deep fixing
box.

Rated single phase 220/240V AC 50Hz input providing 12V 50Hz 30VA
max. safety extra low voltage (SELV) output. Class II double insulated - no
earth required. The controller’s electrical supply must be connected via an
RCD double pole fused connection unit having a contact separation of at

least 3mm in all poles and fitted with a 3amp fuse. This must be sited
outside of a room which contains a fixed bath or shower.
PLEASE NOTE - the controller is only suitable for operating one SELV (extra
low voltage) fan.

1. Fix the (SELV) fan cable and the mains supply cable in position
ensuring sufficient length is left for the connections.

2. Remove suitable cable entry knockouts from the pattress box and
fix in position using screws and (possible masonry plugs) compatible
with the mounting surface.

3. Make the correct electrical connections (See overleaf for which wiring
diagram to follow) to the controller terminal blocks.

4. Refit the controller to the pattress box taking care not to overtighten
the fixing screws or trap any wires.

Upon initial installation, the fan may run continuously for up to 10 days

until the relative humidity has been reduced to an acceptable level.
Prevailing weather conditions can also have an effect and in humid
conditions normal running periods may be extended.

CCLLEEAANNIINNGG
Before cleaning, ensure the controller and fan are isolated from the mains
supply. The front cover of the fan may be cleaned with a damp cloth. The
interior of the fan should also be cleaned occasionally. To do this, first
remove the front cover by loosening its locking screw, then clean carefully
with a dry cloth. If necessary the fan blades may be cleaned with a soft
brush.
