Installation and Wiring Instructions for the ECO MIXED FLOW FAN range.
IMPORTANT: READ THESE INSTRUCTIONS BEFORE COMMENCING THE INSTALLATION
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 temperatures higher than 40°C or less than –5°C.
• Possible obstructions which would hinder the access or removal of the Fan.
•Sudden ductwork bends or transformations close to the Fan.
SAFETY AND GUIDANCE NOTES
A. 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.
B. The Fan should be provided with a local double pole isolator switch having a contact separation of at least 3mm.
C. Ensure that the mains supply (Voltage, Frequency, and Phase) complies with the rating label.
D. The Fan should only be used in conjunction with the appropriate Vent-Axia products.
E. It is recommended that the connection to the fan connecter terminals is made with flexible cable.
F. When the Fan is used to remove air from a room containing a fuel-burning appliance, precautions must be taken to avoid
back-flow of gases into the room from the open flue of gas or other appliance. Ensure that the air replacement is adequate
for both the fan and the fuel-burning appliance.
G. The Fan should not be used where it is liable to be subject to direct water spray for prolonged periods of time.
H. Where ducted Fans are used to handle moisture-laden air, a condensation trap should be fitted. Horizontal ducts should be
arranged to slope slightly downwards away from the Fan.
I. 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.
J. Young children should be supervised to ensure that they do not play with the appliance.
K. Always operate the fan with the flow of air in the correct direction, see the marking on the fan rating label.
A. INSTALLATION.
The unit is designed as an in-line duct fan to be positioned between lengths of ducting. Short duct runs terminating close to the
fan (i.e. within 1.5m) must incorporate suitable guards unless the fan is mounted higher than 2.1m above the floor. If flexible
ducting is used it should be fully extended to obtain the best results. Position the fan at the highest point on the system with both
ducting runs sloping downwards from this point. In circumstances where an excessive amount of moisture is present in the air
then a condensation trap should be installed. When siting the appliance ensure that there is sufficient space to allow access for
any servicing and maintenance.
The eco mixed flow in-line fans can be mounted in any position, For mounting the units we recommend using anti-vibration
mounts and a flexible connector kit to reduce noise transmission into the ducting system. (Available from Vent-Axia)
B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM
THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.

C. MOTOR PROTECTION & CONTROL
*May only be operated with frequency converter (max.230V)
**Thermo contact must be connected to external tripping unit. The internal thermal is not suitable to protect the
motor during a blockage. I.e. in cases where a motor blockage can occur, a motor protection switch with
corresponding rated current should be prefixed. Ideally, we recommend to use a protection switch with thermal and
magnetic release.
***We only recommend frequency converters with sinusoidal filters.

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.
2. When cleaning the fan impeller take care not to move or remove the balance weights.
3. Under no circumstances should the interior be cleaned with water.
4. By installing an air filter in the system, the cleaning interval can be considerably extended.
The Eco Mixed Flow (eMF) fan has sealed for life bearings, which do not require lubrication.
