DESCRIPTION

NBR High Pressure 100 axial extract fans are suitable for domestic bathrooms and W.C’s.

The NBR High Pressure 125 and 150 axial extract fans are suitable for domestic kitchens and utility

rooms. They are available as wall or panel/ceiling mounted models with shutter, timer, humidity and

PIR combinations.

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 duct protected by an exterior air

grille that must comply with the standard

requirements of your country to prevent

access to the fan’s impeller.

2. Cut a 107mm diameter hole for 100mm fans, a

130mm hole for 125mm fans or a 155mm

diameter hole for 150mm fans.

3. Push the two clips on each side of the fan and

pull the grille away from the chassis.

4. Using the built in spirit level bubble as an aid,

mark the screw centres through the holes in

the fan back plate. Drill, plug and screw into

position.

5. After installation, ensure impeller rotates freely and

the shutters can open.

6. Replace the grille and ensure the clips engaged.

WALL MOUNTING

1. For wall mounting either cut a 115mm diameter hole for 100mm fans, a 140mm hole for 125mm

fans or a 170mm diameter hole for 150mm fans, 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. Push the two clips on each side of the fan and pull the grille away from the chassis.

3. Using the built in spirit level bubble as an aid, mark the screw centres through the holes in the

fan back plate. Drill, plug and screw into position. 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 fan’s impeller. The wall kit used in this installation should

provide a minimum ducting length of 100mm from the fans back plate to the inside of the

external grille).

4. After installation, ensure impeller rotates freely and the shutters can open.

5. Replace the grille and ensure the clips engaged.

SETUP

WARNING: THE FAN AND ANCILLARY CONTROL

EQUIPMENT MUST BE ISOLATED FROM THE

POWER SUPPLY DURING THE INSTALLATION / OR

MAINTENANCE.

NBR High Pressure Axial 100,125 & 150 Basic

Single speed fan. Controlled by remote switch (e.g. light switch or auto sensor) Fig.1.

NBR High Pressure Axial 100,125 & 150 Timer

Single speed with overrun timer. The fan can be wired to a lighting circuit switch. Fig.3. or wired for a

basic on/off operation wire as Fig 2.

When switched ‘ON’, the fan will operate at full speed and will continue to run for a pre-set time after

the switch is turned ‘OFF’.

TIMER ADJUSTMENT

BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER SHOULD

ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan grille. The controller is factory set at 15 minutes approx. The overrun

time period can be adjusted from 5-30 minutes by altering the adjuster on the control

PCB. Note the exact min/max time may vary between products.

2. To REDUCE the operating time, use a small screwdriver to turn the adjuster Fig.4.

ANTI-CLOCKWISE.

3. To INCREASE the operating time, use a small screwdriver to turn the adjuster Fig.4.

CLOCKWISE.

4. Replace the fan grille.

NBR High Pressure Axial 100mm PIR

Single speed with PIR (passive infra-red) detector and overrun timer. The fan starts automatically when

a movement is detected and will continue to operate for the set overrun time period. Fig. 1.

The fan can also be wired to a lighting circuit switch. Fig.3. so it can be started by the light switch or the

PIR detector.

TIMER ADJUSTMENT

BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER SHOULD

ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan grille. The controller is factory set at 15 minutes approx. The overrun

time period can be adjusted from 5-30 minutes by altering the adjuster on the control

PCB.

2. To REDUCE the operating time, use a small screwdriver to turn the adjuster Fig.5.

ANTI-CLOCKWISE.

3. To INCREASE the operating time, use a small screwdriver to turn the adjuster Fig.5.

CLOCKWISE.

4. Replace the fan grille.

NBR High Pressure Axial 100,125 & 150 Humidity Timer

The fan contains an integral humidity controller. In automatic mode the controller switches the fan on at

full speed when the room Relative Humidity (RH) increases. The fan will continue to run until the room

RH falls.

These fans also include a built in timer function. This gives the fan a fixed over run time of approx. 15

mins. The timer can be deactivated by removing the Jumper JP1, (Fig. 6)

HUMIDITY SET-POINT ADJUSTMENT

BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY.

HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan grille.

2. To INCREASE SET POINT, turn the adjuster clockwise. This will reduce the internal

Relative Humidity set point at which the fan switches on. (Fig. 6)

3. To REDUCE SET POINT, turn the adjuster anti-clockwise. This will increase the

internal Relative Humidity set point at which the fan switches on. (Fig. 6)

The integral pullcord activates the internal 15 minute timer. The timer can be cancelled by pulling the

pullcord again. The pullcord can be removed by cutting the cord.

COMFORT MODE (Humidity Timer models only)

The Humidity Timer models include Comfort Mode that can be activated via holding the pullcord for 5

seconds.

This feature delays the LS input boost operation for a maximum of 20 minutes to reduce noise and cold

drafts while bathing. After the LS is disconnected, the fan will switch on for the same period the LS had

been active (up to 20 minutes), plus the overrun time period if selected (0 or 15 minutes).

The LED will slowly blink repetitively (every 4 seconds) during comfort mode lead-in time period. The

LED transitions from blinking to solid LED on when LS boost is activated.

The fans internal Relative Humidity sensor is disabled during Comfort Mode.

This feature resets if there is a power cut.

SPEED SELECTION (Humidity Timer models only)

The fan can be set to run on high or low speed depending on the installation requirements.

The fan is factory set to low speed with jumper JP2 fitted. To activate the high speed setting remove

jumper JP2. (Fig. 6)

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.

2. Wipe the inlets and front face with a damp cloth until clean.

The fan has sealed for life bearings, which do not require lubrication.
