Pre-Installation Suitability & Safety Checklist
The following outlines mandatory suitability and safety requirements for installing an EcoOnline™ Solar Attic Fan.
Please read carefully, if any of the following requirements cannot be meet this unit should NOT be installed.
Due to the potential of falling from heights, we recommend that the installation of the
unit on a roof should only be undertaken by a professional installer unless you are
accustomed to and confident of performing the work safely.
At present this fan system is not recommended for installations in cyclonic regions C or
D, or on houses situated on top of hills exposed to extreme winds. It is the responsibility
of the installer to consider wind loading issues as per see AS/NZS1170.2.2011.
Warning: this unit is rated not for bush fire prone areas.
When installing this unit air intake eave grills MUST be installed. Failure to do so could
create negative pressures in the roof cavity and house which could interfere with proper
fluing of carbon monoxide stemming from combustion heating appliances.
This unit is to be installed on relatively flat concrete tile or metal roofs ONLY, not
recommended for highly modulated roof tiles due to the difficultly of flashing.
With the 5 anchor points for the 20W unit should withstand particular strong winds,
however for regions which experience exceptionally strong gale force winds we
recommend a professional installer advise you on wind load issues.
Building regulations vary from state to state and MUST override any instructions supplied
in this manual. It is the responsibility of the purchaser/installer to check that installations
comply with any relevant state laws and regulations.
The EcoOnline™ Solar Attic Fan requires access to the roof cavity to secure metal
strips from underneath the unit to the roof battens.
For metal roofs the unit requires the installation of about 4 eaves grills per unit to aid
air flow.

Safety When Working at Heights
WHEN WORKING AT HEIGHTS - SAFETY COMES FIRST. A person can easily fall off a ladder
or roof and be seriously injured. For installations on a roof pitch greater than 22° and/or a
double story house we strongly recommend a highly competent professional installer install
your solar attic fan. The installer MUST use an appropriate safety harness.
The installer should always take the necessary safety precautions:








Choose an appropriate day: cool, dry, calm and partly cloudy.
Plan out your install: make sure you have all required components, tools and have plenty of allocated time.
Only work at heights when you are well rested and alert.
Never work alone, always work with at least one other person.
Always use a safety harness or fall arrest system attached to appropriate roof anchor points.
Wear clothes that fit well but that do not restrict movement.
Use proper non-slip shoes.
Use sunscreen.
8.1 Ladder Safety
The chance of a falling from a ladder should never be
underestimated. Use only solid industrial grade ladders in good
repair that have been checked for faults.
Note: even a small unexpected movement of the ladder, such
as a small slip, can cause loss of balance and result in a fall.
The ladder should be placed on solid ground and should
ALWAYS be securely anchored at the base and secured at the
top to prevent slipping. Always have one person

Choosing a place to install the Solar Attic Fan
When choosing a location for your attic fan you should consider the following:






You’ll need roof cavity access to fasten attachments under the unit.
Unit should be free from shading (this includes overhead cabling or TV antennas).
Should be installed preferably between roof rafters.
The unit should be installed as high up on the roof as possible.
For a metal roof the flashing base should go under the ridge cap.
For a tile roof the unit should be installed at least three tiles down from the ridge capping so as not to
damage it during installation.

10 Optimal Solar Panel Orientation
10.1 Single Panel Unit
The solar panel should be orientated so that peak power production coincides with the maximum temperatures in
the daily diurnal cycle in summer (which typically peaks at between 2-3pm). Hence, the panel should be tilted at
about at L - 10° (where L is your latitude) and tilted west toward the sun’s position at between 2-3pm.
10.2 Bi-Panel Unit
Bi-panel units should have a first panel facing the 11am-12noon sun with the second panel facing the afternoon sun
to create a broad power peak. It does not matter which panel faces the afternoon sun. Since the unit’s solar panel is
adjustable it is recommend that the unit’s solar panel face the afternoon sun, while the second panel can be
mounted flat on a north facing roof.
11 Plan your installation first
For your added safety the EcoOnline™ Solar Attic Fan comes with a separate universal square flashing template
so that most of the flashing work can be done conveniently and safely on the ground minimizing time spent on
the roof.
1. Place the template around the unit and mark the overlap lines (40mm overlap).
2. On the roof, use the template to plan your installation.
3. Mark all screw holes, bend lines, cut lines on the square flashing and on the roof.
12 Attaching the flashing
When working with power or hand tools always follow the safety instructions.
 Where appropriate wear the recommended personal protective equipment, such as
gloves, safety glasses, respiratory and hearing projection.
 Make sure electrical cables are kept away from any water and from foreign objects
which pose a potential cable severing or crushing hazard.
 When using glues, solvents or sealing agents make sure you know and seek the
proper first aid in case of an accident.

Cover a table with a plastic drop sheet and lay the unit on the edge of the table.
Apply a small (2mm diameter) spherical bead of silicon around the top base of the unit.
Lay the flashing in place on the silicon.
Clamp the top overlap area of the flashing halves to the base of the unit.
Drill one rivet hole in this top overlap area and rivet the three pieces in place (rivet from the bottom).
Re-align the two halves of the flashing so that the bottom edge runs straight.
Starting from this top rivet, drill and rivet the next two holes on either side.
Follow clockwise and anti-clockwise on either side until the bottom is reached.
The last rivet should fasten the bottom section.
Do not rivet the two opposing ends first as this may create modulations in the mid section of the flashing.
Place more silicon all around the edge of the flashing (top and bottom) and rivet points.
Finish by drilling, cutting and bending the flashing appropriately by using your markings and the edge of the

Attach the metal securing strips to the body of the unit.
Fix the appropriate angle of the solar panel making sure the bolts holding the panels are done up tight.
Cut the solar panel wind proofing Aluminium side struts to length and install (20W version only).
On the roof, remove tiles by sliding top tiles up and removing the bottom tiles for cutting (if applicable).
For a metal roof undo ridge capping screws, cut a 45cm diameter hole using tin cutters.
Insert the finished unit in place and secure using fixing screws.
Put tiles back and run silicon under any side tiles and side flashing overlaps.
Finally remove the solar panel cover.
In the roof cavity, secure the metal strips using a screw to the nearest roof batten.
During the installation the solar panels must be disconnected to prevent the unit from
inadvertently activating during the install. The motor can be burn out if the unit activates
while the fan blades are not free to move.

To minimize time spent on the roof, most of the flashing work should be performed on the
ground.
Important: ALWAYS install wind proofing struts for the 20W version when mounting the
unit in cyclonic and/or strong wind areas.

Important: The securing screws MUST be drilled through the unit’s thicker gauge steel
circular flashing and NOT just through the add-on square flashing.
Some non-flat roof tiles may require extra flashing to seal the bottom run off of the unit.
If in doubt seek advice.

Option 3, may require the square flashing base to be attached beneath the unit’s existing
circular flashing, as opposed to on top of the unit’s flashing.
14 Adjusting the Thermostat
The activation temperature of the fan can easily be adjusted using the existing (27°C) fixed temperature thermostat.
For example if you require the unit to activate more often (i.e. a at lower roof cavity temperature) simply cut and
extend the thermostat wire and situate the thermostat higher in your roof cavity.
On the other hand situating the thermostat lower in your roof cavity will result in the thermostat sampling cooler air
- in this case the unit will not come on as often.
If a complete removal of the thermostat is required simply cut off the thermostat and join the two resulting wires

(see figure below).
Note: when extending/altering wiring, the extra wire should be double insulated dual
core PVC cord with minimum copper area 0.75m2. All solder joins must be sealed using a
good quality adhesive lined heat shrink.
Never run a 12-24V cable near or in the same compartment or conduit as other 240V cables
due to the chance of mistaking the two cables at some later point in time during installation
or servicing.
15 Trouble Shooting
Problem
Unit in full sun and not working
Flashing will not lie flat around the
fan base
Cause
Thermal switch
prevents the unit from
activating below 27°C
Rivet holes were not
aligned properly
Solution
No fix required
Create a small bend running the length of the
flashing, alternatively, bend U clips and use them
to clip the flashing to the roof tile on either end,
silicon in place.
