8. To avoid the risk of fire, do not use the product in the presence of inflammable substances or
vapours such as alcohol, insecticides, gasoline, etc.
9. The air or fumes being extracted must be clean and free from greasy particles, soot, chemicals and
corrosive agents, inflammable or explosive mixes (if these substances are treated, conctact an
authorised dealer for information on a specific range of explosion-proof products).
10. The device must be installed by professionally qualified personnel.
11. The product must be connected to the electricity supply by means of a double-pole switch with a
minimum contact opening distance greater than 3 mm.
12. To ensure optimum operation, do not block the air intake and exit vents.
13. The room where the device is located must be adequately ventilated to ensure correct operation
(UNI CIG 7129).
14. If the fan is sited in a room containing a fuel burning appliance, the installer must ensure that air
replacement is adequate both for the fan and the fuel burning appliance.
15. The unit should not be used as an activator for water heaters, stoves, etc.
16. Any ducting used must be free from blockages
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)
18.
THIS APPLIANCE IS PROVIDED WITH THERMAL OVERLOAD PROTECTION. IF THIS IS ACTI-
VATED, THE FAN MUST BE DISCONNECTED FROM THE MAINS ELECTRICITY SUPPLY. THIS
WILL ALLOW THE OVERLOAD DEVICE TO RE-SET. AFTER A BRIEF PERIOD, THE FAN CAN
BE RE-STARTED. IF THE FAULT PERSISTS, CONSULT VECTAIRE FOR FURTHER ADVICE.
OPERATION
1.
The
Microbox
is suitable for ceiling or wall installation (Fig. A)
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.
These fans run continuously at a preset trickle speed and have an independently switched boost
speed. There is a choice of four trickle speeds, selectable during the installation by adjusting the
dial on the top of the casing (Fig 9B).
4.
The boost speed can be triggered by:
-
PIR (passive infra red)
-
DRH (dynamic remote humidistat)
-
AQS (remote air quality sensor)
-
THM (thermostat)
-
remote switch (which can be a light switch)
5.
All the fans have an integral, over-run timer which is adjustable on installation from 0 to 25 minutes
(Fig 9A). This controls the length of time that the fan will continue to operate at its boost speed
once this has been triggered, and after:
-
if using a PIR, there ceases to be anyone within the scope of the PIR
-
if using a DRH, after the relative humidity has dropped to the pre-set level of the humidistat
-
if using an AQS, when the air quality has returned to an acceptable level
-
if using a THM, when the temperature has dropped to an acceptable level
-
if using a remote switch, when it is switched off.
