Installation and Wiring Instructions for the ACH IN-LINE CENTRIFUGAL DUCT 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.

If the unit is to be stored for a long period of time the fan impeller must be rotated by hand at monthly intervals to prevent hardening of the

lubricant and corrosion or static indentation of the bearings.

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. Note:- This is a class 1 appliance and MUST be earthed.

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.

B. WIRING.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM

THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.

THE ACH FANS ARE CLASS 1 AND MUST BE EARTHED.

1. Remove terminal box cover and put to one side.

2. Select and follow the wiring diagrams. Connect the power supply from the local isolator (via any appropriate

controls if fitted).

3. Ensure that all earth connections have been made and that no connection is made to the brown motor wire.

4. Check all connections have been made correctly and ensure all terminal connections and cable grommets are

securely fastened.

5. The cable entry must be made using the cable grommets provided in the terminal box.

6. Replace terminal box cover.

7. Ensure the impeller rotates and is free from obstructions

C. OVER-HEATING PROTECTION.

The fan motor is fitted with Thermal Overload Protection. This will automatically switch the fan off in the event of a

fault condition. If this occurs isolate the fan, check for and remove any obstruction, leave for a short time for the

motor to cool before reconnecting. If this recurs, Isolate and call your service engineer.

D. SERVICING AND MAINTENANCE.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED

FROM THE POWER SUPPLY DURING MAINTENANCE.

1. It is recommended that the fan be inspected after three months or sooner if conditions dictate. If a build up of

dirt/deposits is evident then this should be carefully cleaned off. Please take care not to damage the fan or affect

the balance of the impeller motor assembly (balance weights may be fitted to the impeller).

2. Further inspections should be carried periodically as necessary dependant on experience and site conditions. It

is recommended that a minimum of two inspections per year be carried out.

The ACH fans have sealed for life bearings, which do not require lubrication.
