IMPORTANT Note Regarding Lifting This Product

Lift the product in its original packaging using a crane or similar equipment to roof mounting location –prior

to handling the product.

Caution:

The ventilator top surface/dome can be easily scratched or deformed when placed upside down so always

place it on a soft/smooth surface such as cardboard or a soft-foam mat.

SAFETY AND WARNINGS

a. Please read this manual carefully before installing this product and keep it for future reference or

provide it to the building owner/maintenance manager.

b. The installation of this product involves working at heights on a sloping surface and may be dangerous

which includes the potential of death, personal injury, or property damage. Please be aware of the

following before installing this product.

c. Follow the state or territory regulator OH&S guidelines for working at height (e.g. Roof work), electrical,

working in elevated temperatures (e.g. roof space in summer). For more information on your state’s

OH&S guidelines for working at heights, please refer to: https://www.safeworkaustralia.gov.au/heights

d. This product must be installed by a qualified installer and all electrical wiring must be undertaken by a

qualified electrician.

e. This hybrid ventilator uses 220V-240V AC power for the electrically powered components and electrical

connections must only be undertaken by a qualified electrician.

f. This hybrid ventilator is supplied with either a Smart Controller or Interface Box - these devices must not

be tampered with and the hybrid ventilator must not be operated without either of these devices.

g. Do not attempt to power up the product when the product is not suitably roof mounted as the turbine

will rotate without warning and may create a hazard.

h. Due to the size and weight of the turbine, it is recommended that it is always lifted by 2 people or a

crane. Refer to the lifting instructions.

i. Damaged parts must be replaced with a genuine replacement part from Bradford Ventilation.

3. VENTILATOR POSITIONING & PROVISION FOR MAKE-UP AIR

Bradford Ventilation recommends that ventilators are positioned 4m to 6m away from each other in all

directions for effective and efficient performance. Ensure that the ventilators are not sheltered from the wind

by surrounding objects, the angle created by the roof ridge or from each other.

Make-up air is required for this hybrid ventilator to replenish the exhausted air. As a general guide, the

largest make-up air entry should be positioned on the opposite side of the building to the largest ventilator

demand. The make-up air location should be positioned at optimum height to provide efficient sweeping of

the area.

The illustrations below provide a number of generic ventilator and make-up air layouts but it should be

noted that a whole-of-building assessment, as per AS1668.2, should be conducted by a suitably qualified

person prior to deciding upon site-specific ventilator and make-up air placement.

IMPORTANT: If insufficient external make-up air is provided, the ventilators will draw make-up air from each

other –this will both diminish the effectiveness of the system and increase the risk of the system drawing

external water into the building during periods of rain.

4. VENTILATOR INSTALLATION –Ridge Installation

NOTE: Cyclonic application variations to these instructions are set out in Section 6.

a. Set Position: Place the base flashing under the ridge cap in the required position and adjust position to

avoid structural roof members below the roof sheet.

Important Note Regarding Roof Structural Support:

EP400 & EP600 –If the purlin spacing is larger than 600mm, trimmers are required. Install the

trimmers between the purlin on the either side of the opening. Do not cover the openings.

EP900 –If the purlin spacing is larger than 1000mm, trimmers are required. Install the trimmers

between the purlin on the either side of the opening. Do not cover the opening.

b. Mark Hole Position: Ensure the flashing covers the corrugation or ribs equally on each side of

the flashing, then mark a circle on the roof using the hole in the flashing as a template.

c. Cut Hole: Carefully cut the hole, remembering that there may be insulation and other roof

members under the roof sheet. Once the hole has been cut, fold up the edge of the

corrugations or pans.

d. Secure Flashing: Attach the flashing to the roof (refer to the table below for the required

number of fasteners). If trimmers are used ensure the flashing is secured to the trimmers. Seal

all fasteners with suitable sealant to ensure they are weatherproof.

e. Assemble the Varipitch: When a Varipitch throat is being used, place the Varipitch on the

flashing and rotate the top and bottom halves until the top of the Varipitch is level (horizontal) -

it is recommended that an electronic or spirit level is used to ensure that the top edge of the

throat is horizontal in all directions.

Secure the Varipitch angle: With the varipitch upper throat positioned horizontally, lock it into

position using the supplied varipitch clip. Use either self-tapping screws or blind rivets to

secure the clip between the two halves of the varipitch.

f. Weather Sealing: Seal the Varipitch seam on the inside with a bead of weather-resistant

suitable sealant.

NOTE: DO NOT apply sealant to the joint between the flashing and Varipitch. This is a natural

gutter to release any trapped condensation.

g. Secure Varipitch to Flashing: Secure the varipitch to the flashing using the recommended

number of screws shown in the table below –DO NOT seal this connection.

h. Assemble Turbine: Assemble the turbine head to the Varipitch. Re-check if the assembly is

level (horizontal) and adjust the turbine by tilting the throat slightly if required. Ensure the

knurling (the tapered section of the Varipitch) is fully inside the ventilator throat and secure the

ventilator throat by fastening it to the top of the Varipitch with the number of fasteners shown in

the table below.

i. Sealing is crucial for this product to ensure no leaking occur during its lifespan. Ensure the

following areas are sealed;

5. VENTILATOR INSTALLATION –Away from Ridge Line - Back-Flashing Required

NOTE: Cyclonic application variations to these instructions are set out in Section 6.

a. Hole Layout: It is recommended that 1 dry pan is flashed on each side of the ventilator throat

cut-out. If the ventilator diameter is greater than 1 pan width and less than 2 pans width –cut a

square hole for 2 pans.

Note :

EP400 & EP600 –If purlin spacing larger than 600mm, trimmers may be required. Install the

trimmers between the purlin on the either side of the opening. Do not cover the openings.

EP900 –If purlin spacing larger than 1000mm, trimmers may be required. Install the trimmers

between the purlin on the either side of the opening. Do not cover the opening.
