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.

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

Manrose 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.
