15. Any ducting used must be free from blockages
16
.
Where ducting is installed in an unheated space, all of the ducts should be insulated.
17. Your fan must not be exhausted into a duct which is already used for any other purpose (see Approved
Document F1 2006 for guidance)
OPERATION
1. The
Microbox
is suitable for ceiling or wall installation.
2. If one of the spigots is not connected to ducting, a safety grille
MUST
be fitted to that spigot, so that it is
impossible for any moving part to be touched.
3. This fan runs continuously at a preset trickle speed and has an independently switched boost speed. The
trickle & boost speeds are selectable during the installation by adjusting the trimmers in the controller (see
wiring diagrams).
4. An overrun timer is fitted to this product. When the boost is switched off, the fan will continue to run at boost
speed for up to 20 minutes, after which the speed will return to trickle. The length of the overrun period can
be adjusted from 0-20 minutes using the TIMER adjustment on the control board (see page 6).
NOTE:
for models incorporating an internal humidistat, the boost speed will also be activated whenever the humid-
ity level of the extracted air rises above a preset level (factory set). When the humidity level is reduced back below
the preset level, the fan will return to normal (trickle) speed.
ELECTRICAL CONNECTION
WARNING: these appliances must be earthed and all wiring must conform to current IEE Regulations and all
applicable standards and Building Regulations.
• The unit is suitable for 230V, 50Hz Single phase supply fused.
• The unit is supplied with a mains rated 4 core flexible cord (black, brown, grey and green/yellow)
• A triple pole switch having a minimum contact separation of 3mm must be used for isolation and located close
to the product.
• Boost controls must not be located within 1 metre of a cooker or where they may be affected by excessive heat
or moisture
• Boost controls should be clearly identified and conveniently located.
• The boost speed can be triggered by a switched live connection from a variety of external devices including:
- PIRFF (passive infra red)
*
- DRH240 (dynamic remote humidistat)
*
- THM (thermostat)
*
- a light switch (if more than one light switch is used,
each one must be a double pole switch)
- a remote switch/pull cord
(
*
PIRFF, DRH240 and THM may have integral over-run timer which controls the length of time that the fan will
continue to operate at its boost speed after the boost has been switched off)
