DESCRIPTION
The MON-CON 100mm fan is a continuously running extract fan for kitchens, utility
rooms, bathrooms and toilets. The fan can be wall or panel/ceiling mounted.
A. INSTALLATION
IMPORTANT: The fan should only be used in conjunction with fixed wiring.
PANEL/CEILING MOUNTING
1. For panel/ceiling mounting the fan should be installed into a closed duct system of
at least 1.2m long or protected by an exterior air grille that must comply with the
standard requirements of your country to prevent access to the fans impeller.
2. Cut a 105mm diameter hole.
3. Loosen the screw at the bottom of the grille and remove the front grille. Mark the
screw centres through the holes in the fan back plate. Drill, plug and screw into
position.
4. Attach ducting as required for the installation.
5. Wire the fan as described in the Wiring section. Adjust any settings as required
(see Setup section).
6. Replace the grille and tighten the retaining screw.
7. After installation, ensure impeller rotates freely.
WALL MOUNTING
1. For wall mounting cut a 115mm diameter hole through the wall and insert the wall
sleeve. Slope the sleeve slightly downwards away from the fan. Cut to length and
cement both ends into position flush with the wall faces.
2. Loosen the screw in the bottom of the grille and remove the front grille. Mark the
screw centres through the holes in the fan back plate. Drill, plug and screw into
position.
3. Fix exterior grille into position with the louvres positioned downwards. (Note:- The
grille must comply with the standard requirements of your country to prevent
access to the fans impeller).
4. Wire the fan as described in Section B-Wiring. Adjust any settings as required
(see Section C-Setup).
5. Replace the grille and tighten the retaining screw.
6. After installation, ensure impeller rotates freely.

B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION / OR
MAINTENANCE.
IMPORTANT
The fan should only be used in conjunction with fixed wiring.
The cross - sectional area of supply cord used should be ranged from 1 -1.5mm2.
Cable entry can only be made from the rear of the fan.
The extraction fan is suitable for connection to 220-240V 50Hz supply.
The fan is a class ll double insulated product and MUST NOT be earthed.
1. Select and follow the appropriate wiring diagram. (Fig. 1, 2 or 3)
2. Check all connections have been made correctly and ensure all terminal connections and
cable clamps are securely fastened.
3. Ensure the impeller rotates and is free from obstructions.
C. SETUP
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION / OR
MAINTENANCE.
ACCESSING THE CONTROL SETTINGS – (Fig. 4 and 5)
1. Loosen the screw in the bottom of the grille and remove the front grille.
2. Carefully pull the inner cap from the centre of the fan away from the chassis.
3. Adjust the settings as outlined below.
BEFORE SETTING THE SPEED, SWITCH OFF THE MAINS SUPPLY. SPEED SHOULD
ONLY BE SET BEFORE OR DURING INSTALLATION.
TRICKLE SPEED SELECTION (6l/s or 9l/s) – (Fig. 7)
In normal running mode the fan can extract at either 6l/s (22m3/h) or 9l/s (32m3/h) flow rate. The
fan will boost to 15l/s (54m3/h) when the LS connection is switched.
Factory set at 6l/s (22m3/h).
Remove jumper connector (JP1) if 9l/s (32m3/h) extract flow rate is required.
BOOST SPEED SELECTION (Fig. 8):
The fan has two boost speed settings for different installation requirements:
1) Max speed: Dip switch 2 in the ‘OFF’ position.
2) 15l/s speed: Dip switch 2 should be in the ‘ON’ position.
(Factory set)
Dip switch 1 should be in the ‘ON’ position for constant trickle mode.

TIMER ADJUSTMENT (T & H MODELS) (FIG. 7)
BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER SHOULD
ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION
IMPORTANT NOTE:- ON T& HMODELS THE TIMER IS ACTIVATED VIA THE LS
CONNECTION.
1. Remove the fan grille. The overrun timer is factory set to approximately
15 minutes. This timer period can be adjusted between approximately 3-30
minutes by altering the adjuster on the control PCB.
2. To REDUCE the operating time, use a small screwdriver to turn the adjuster Fig.7.
CLOCKWISE.
3. To INCREASE the operating time, use a small screwdriver to turn the adjuster
Fig.7. ANTI-CLOCKWISE.
4. Replace the fan grille.
HUMIDITY SET-POINT ADJUSTMENT (H MODELS) (FIG. 7)
BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY.
HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.
1. Remove the fan grille. The controller is factory set to switch on at about 70% RH.
The humidity set point can be adjusted from 65-95%RH by altering the adjuster on
the control PCB.
2. To LOWER the set-point use a small screwdriver to turn the adjuster Fig.7. ANTI-
CLOCKWISE. This makes the controller MORE sensitive.
3. To RAISE the set-point use a small screwdriver to turn the adjuster Fig.7.
CLOCKWISE. This makes the controller LESS sensitive.
4. Replace the fan grille.
D. SERVICING AND MAINTENANCE.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to
ensure there is no build up of dirt or other deposits.
Ensure that the fan is switched off from the supply mains before removing the grille.
2. Carefully pull the front panel of the grille away from the base part of the grille
(fig. 6).
3. Wipe the inlets and front face with a damp cloth until clean.
The fan has sealed for life bearings, which do not require lubrication.
