DESCRIPTION
As standard, the Centrif Duo and Centrif Duo Plus are suitable for panel/wall installations, surface
mounting, either in a horizontal or vertical plane. A Flush Mount Kit (439256) is available as an
accessory. Ø100mm ducting (flexible or rigid) can be attached providing rear exit as standard or
side exit with the Flush Mount Kit. Adaptors for rectangular ducting can be used. For wall
installations a Wall Kit (25 41 02 White / 25 41 00 Brown) can be used. Please see our catalogue
or web site (www.vent-axia.com) for more information on ducting and termination options.
A. INSTALLATION
A Backdraught Shutter Assembly is supplied. It is packed inside the product during transport. It is
designed to block the duct when the fan is off in order to prevent cold draughts from outside
entering the building. To use it, push it on to the end of the exhaust Spigot (fig.1) with the hinges
on the flaps vertical. It is not required when the fan is set up to run continuously.

B. SETUP
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING INSTALLATION OR
MAINTENANCE.
TO ACCESS THE SPEED CONTROLS/PCB, REMOVE THE 2 SCREWS
HOLDING THE PCB COVER IN PLACE (SEE FIG 4).
1. SELECTING THE CONSTANT TRICKLE (with Boost) OPTION
All models have the ability to have a constant trickle speed with an option to boost if
required. To enable constant trickle, please refer to fig 7 and below:
i) P model: Link terminals 5 and 6.
ii) DP model: Pull pullcord until in the trickle speed has been selected. If you want to
just use the LS to switch the DP model between trickle and boost, first set the fan
running to trickle speed with the pull cord, then remove the pull cord string.
iii) T and HTP models: Move dip switch 4 into the ON position.
2. SELECTING THE BOOST SPEED.
All models can boost to a higher speed via LS connection or Pullcord (pullcord not
available on T model). The HTP model can boost to different speeds for Timer (LS) and
Automatic Humidistat functions.
i)
P Model: Link terminal 4 to one of the following:
a. Terminal 1 = Low speed (same as trickle speed)
b. Terminal 2 = Medium (Utility) speed
c. Terminal 3 = High (Kitchen) speed
ii)
DP model: Link terminal 3 to one of the following:
a. Terminal 1 = Medium (Utility) speed
b. Terminal 2 = High (Kitchen) speed
5
iii)
T model: Move one of the following dip switches into the ON position.
a. Dip switch 1 = Low speed (same as trickle speed)
b. Dip switch 2 = Medium (Utility) speed
c. Dip switch 3 = High (Kitchen) speed
iv)
HTP model: The HTP model has two boost speed options, one speed option
for the Timer function (via LS) or pullcord and another speed selection for the
Humidistat function. Move one dip switch into the ON position for LS/pullcord
and one for Humidity speed selection. It is recommended for both Kitchen and
Utility room installations to set the Humidity Boost speed to Medium (utility).
This will ensure the room is kept dry but reduce the noise from the fan.
a. Dip switch 5 = Humidity Boost Low speed (same as trickle speed)
b. Dip switch 6 = Humidity Boost Medium (Utility) speed
c. Dip switch 7 = Humidity Boost High (Kitchen) speed
d. Dip switch 1 = LS/Pullcord Boost Low speed (same as trickle speed)
e. Dip switch 2 = LS/Pullcord Boost Medium (Utility) speed
f.
Dip switch 3 = LS/Pullcord Boost High (Kitchen)
3. TIMER ADJUSTMENT (T and HTP models only)
The overrun time period is factory set to about 15 minutes. The overrun time period may
be adjusted from about 1-30 minutes by altering the lower adjuster of the two on the
control PCB (fig.4 & 7).
i.
ii.
To REDUCE the operating time, turn the timer adjuster ANTI-CLOCKWISE.
To INCREASE the operating time, turn the timer adjuster CLOCKWISE.
4. RELATIVE HUMIDITY ADJUSTMENT (HTP model only)
NOTE:- On installation it is possible that the humidity controller will run continuously until
it has acclimatized to the environment.
The fan’s relative humidity (RH) set-point is factory set to switch the fan on at about
75%RH. This set point can be raised or lowered by altering the upper adjuster of the two
on the PCB (fig.4 & 7).
i.
ii.
To LOWER the set-point, turn the humidity adjuster (fig.4 & 7 ) ANTI-CLOCKWISE. This
makes the fan more sensitive to RH, i.e. the fan will come on at a lower RH.
To RAISE the set-point, turn the humidity adjuster (fig.4 & 7) CLOCKWISE. This makes
the fan less sensitive to RH, i.e. the fan will come on at a higher RH.
The fan will continue to run at boost after the RH has dropped below the set point for the
time period set by the timer adjustment (see 3. TIMER ADJUSTMENT, above)
