Installation and Wiring Instructions for the ManiVent MANI3000N.
IMPORTANT:
READ THESE INSTRUCTIONS BEFORE COMMENCING THE INSTALLATION
SAFETY AND GUIDANCE NOTES
1. DO NOT install this product in areas where the following may be present or occur:
1.1. Excessive oil or a grease laden atmosphere.
1.2. Corrosive or flammable gases, liquids or vapours.
1.3. Ambient temperatures higher than 40°C or less than -5°C.
1.4. Possible obstructions which would hinder access or removal of the Fan.
2. All wiring to be in accordance with the current I.E.E. Regulations, or the appropriate standards of your country and
MUST be installed by a suitably qualified person.
3. The fan should be provided with a 3A fused, isolator switch capable of disconnecting all poles, having a contact
separation of at least 3mm.
4. Ensure that the mains supply (voltage, frequency, and phase) complies with the fan’s rating label.
6. When the fan extracts air from a room containing an open flue of a gas or fuel burning appliance, precautions
must be taken to avoid the back-flow of gases into the room.
7. The fan should not be used where it is liable to be subjected to direct water spray.
8. The fan should be mounted at the highest point in the system to protect it from condensation build up.
9. This fan should be vented to the outdoors.
10. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
11. Children should be supervised to ensure that they do not play with the appliance.
12. PLEASE NOTE: Some older fluorescent and low energy lighting products can interfere with other
electronic/timing circuits. For reliable operation of timers use post 2000 low energy bulbs or tungsten filament bulbs
in the room lighting circuit.
TYPICAL INSTALLATION

A. INTRODUCTORY NOTES
The MANI3000N is an M.E.V (Mechanical Extract Ventilation) unit designed for simultaneous extract ventilation of
multiple areas such as bathrooms, kitchens and toilets. The MANI3000N employs a highly efficient backward curved
centrifugal motor impeller set and is designed for continuous 24-hour use.
The MANI3000N has 3 speed settings, High, Medium and Low, these are not adjustable.
The speeds are selectable via the 2 LS inputs.
The product will run at Normal speed unless the input from an accessory calls for a change to Boost or Purge speed.
For the MANI3000A the Boost setting is activated using a switched live supply (LS input). The other remaining LS
input can be used to switch the unit to Purge speed.
B. SITING
DO NOT install this product in areas where the following may be present or occur:
•Excessive oil or a grease laden atmosphere.
•Corrosive or flammable gases, liquids or vapours.
• Ambient exhaust air temperatures higher than 40°C or less than –5°C.
•Relative humidity above 90%
• Possible obstructions which would hinder the access or removal of the Unit.
•Sudden ductwork bends or transformations close to the Unit.
The MANI3000N can be mounted in 3 orientations for convenient installation in roof voids with a height ≥250mm.
a). Base mounted Installation with ducting radiating out horizontally.
b). Vertically mounted Installation with the exhaust spigot at top. The electrical connections must come out of the
bottom of the unit in order to maintain the water ingress protection rating.

c). Ceiling mounted Installation.
See the dimensional details below for the mounting hole positions.
-Spigot diameters are 125mm
C. INSTALLATION
To reduce the system resistance in your duct system, and therefore lower the speed, power consumption and noise
of the fan, please follow these instructions:
•Keep the length of duct runs to a minimum, particularly the exhaust duct run.
•Use larger diameter ducting rather than smaller.
•If you need to use flexible ducting, make sure that it is fully extended and not crushed, sagging or torn.
•Try to minimise the use of dampers by having similar length duct runs to the inlets.
•The bend radius, (measured to the inside of the bend), should be at least 1x the duct diameter. The larger,
the better.
•Avoid having any bends, filters or other obstructions within 250mm of the fan inlets and outlet.
1. Position the MANI3000N, taking into consideration the position of the rooms to be ventilated, the exhaust
position, the drainage position and the electrical services. Ensure there is adequate access for installation
and maintenance. Securely mount the MANI3000N through the mounting brackets on the casing using the
appropriate anti-vibration mounts, screws, washers, rubber bushes etc.
2. Ducting passing through an unheated space should be insulated.
The MANI3000N can be connected to either Ø125mm or Ø100mm ducting. Remove the blanking caps to
connect Ø125mm ducting. To connect Ø100mm ducting, peel out the centre of the cap with a screwdriver as
indicated on the cap and leave the cap surround in position.
Please note that the exhaust duct must always be Ø125mm ducting.

D. WIRING
WARNING: THE MANI3000N AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
THE MANI3000N UNIT MUST BE EARTHED.
Access to the MANI3000N connection terminals is under the top cover which is retained by four screws. Ensure that
the mains supply voltage, frequency, number of phases and power rating comply with the details on the rating label
positioned under the top cover.
All wiring must be in accordance with local and/or national electrical codes as applicable or the appropriate standard
in your country (BS7671 in the UK). The MANI3000N must be supplied through a double-pole isolating switch, having
a contact separation of not less than 3mm. Cable clamps are provided for use with the cable or flex on entry into the
MANI3000N.
The MANI3000N has three speed settings. Select the required speed and wire as indicated in Figure 1.
Alternatively the MANI3000N may be wired in a number of different ways to achieve optimum ventilation control.
Figure 2 shows a wiring diagram to provide 3-speeds selectable by a remote switch.
Figure 3 shows a wiring diagram for automatic switching from medium to high speed using an external sensor.
1. Connect mains supply as (Fig. 1,2 or 3 below)
2. Check that all connections have been made correctly. Ensure that all terminal screws and cable clamps are
securely fastened.
3. The cable entry must be made using a suitable grommet or cable gland.
4. Replace cover using the 4 screws provided. Switch the mains supply on and check the system is operating
correctly.

E. OVER-HEATING PROTECTION
The MANI3000N motor is fitted with Standard Thermal Overload Protection. This will automatically switch the fan Off
in the event of a fault condition.
If this occurs isolate the MANI3000N, check for and remove any obstruction, leave for a short time for the motor to
cool before reconnecting. If this recurs, Isolate the MANI3000N and call a service engineer.
F. COMMISSIONING
Select the speed needed based on the size and ventilation requirements of the dwelling.
G. SERVICING AND MAINTENANCE.
This product contains a self-cleaning backward curved impeller that requires no servicing.
The fan has sealed for life bearings, which do not require lubrication.
