EVOAQ Ventilation with Heat Transfer Upgrade
Thank you for your purchase of our company’s product. It has been manufactured following
current technical safety regulations and is in compliance with AS/NZ60335 standard.
Please read this instruction booklet carefully before installing or starting up the
product.
It contains important information on personal and user safety measures to be followed while
installing, using, and carrying out maintenance work on the equipment. Once the product
has been installed, please hand this booklet to the end user.
The fans and electronics included with this system are designed as simply plug in
and go while requiring very little user intervention.
The system includes 2 fans, one for ventilation and one for heat transfer. Both fans contain
smart in-built electronics which are constantly monitoring temperature and humidity levels
of the air flowing through the fans. They use this information as well the the settings from
the wall controller to determine what speed to run at, varying their speed between very low-
and very high rates (10 - 100%) as required.
In ventilation mode, the system is designed to supply fresh air to all living areas in the house
at a rate at which the thermal comfort of the house is not affected by the ventilation system.
The heat transfer fan is turned off in this mode.
In heat transfer mode, the heat transfer fan takes excess heat from the heat source room
and redistributes it to the bedrooms. In this mode the ventilation fan continues to provide
fresh air to the heat source room, which is distributed throughout the rest of the house by
the heat transfer fan.
The heat transfer fan is designed to continue transferring heat at low levels even while the
heat source room is cooling down (e.g. at night when everyone has gone to bed) and as long
as there is still some lingering heat that the bedrooms may benefit from. Maintaining correct
ventilation even while heat transfer is active is important in order to prevent condensation
issues and energy losses and to allow you to enjoy a healthier indoor environment.
INSTALLATION OVERVIEW
Before commencing installation, select suitable places for the fans and filter box to be
installed in the ceiling cavity. It is recommended to place the filter and ventilation fan near
the manhole for easy access when carrying out maintenance to the system. Place the filter
before the fan to protect the fan from dust and dirt buildup. Place the heat transfer fan close
to the manhole if possible, and if not possible ensure it is placed in a location that is easily
accessible for servicing.
Suspend the fans from the ceiling framing with the chain and cable ties provided in order to
minimise the sound levels resonating through the ceiling framing.
If the ventilation system will be taking air from outside or the fan or air inlet is installed in
external walls, care must be taken to avoid the backflow of gases into the system from gas
califonts, open gas flues, or other open-fire appliances.
Acoustic ducting is provided for the reduction of fan motor noise. Connect 1-1.5m of acoustic
ducting to the outlet of each fan, and 2-3m of acoustic ducting to the inlet side of the heat
transfer fan (between the inlet grille and fan). Ensure both the inner ducting and outer
sleeve are fully taped onto the fan, and the outer sleeve of the acoustic ducting is without
tears or holes.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.
Take care not to place the heat transfer inlet grille too close (within 1.5m) to the heat source,
as the air generated can exceed the temperatures that the fan is designed to operate under.
If the intake air is too hot the fan may shut down or be damaged. We recommend placing
the heat transfer inlet grille 3-6m away from the heat source where possible.
Please note:
The inlet of the fan unit is on the side of the fan blades, the side that is not obstructed by
the fan frame. There are also arrows on the unit and rating label showing airflow direction.
Please be aware that the system is designed for air to flow from the filter box, through the
ventilation fan, and to the rest of the house on the ventilation side, and for air to flow from
the inlet grille, through the heat transfer fan, and into the bedrooms on the heat transfer
side. Ensure the fans are oriented correctly for this during installation.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.

If the circuit protection device is tripping during operation, the apparatus must be quickly
disconnected from the mains supply. The whole installation should be carefully checked
before trying to start up the machine again.
MAINTENANCE AND REPAIR
Before servicing the fan, make sure it is disconnected from the mains supply - even if it has
previously been switched off. Avoid the risk of anyone else plugging it in while you’re
working on it.
The fan must be regularly inspected. These inspections should consider the fan’s working
conditions, ensuring no dirt or dust builds up on the propeller, turbine, motor or grilles. This
could be dangerous and perceptibly shorten the fan’s lifespan. While cleaning, take extra
care not to damage the propeller. The filters should be checked at least every 12 months, and
replaced at least every 2 years, or earlier if necessary. Any and all maintenance work should
be carried out in strict compliance with New Zealand safety regulations.
All our products contain repairable or replaceable parts. Repair or replacement of these parts
should only be handled by the manufacturer. In the case of damage or malfunction of the
fan, please contact the manufacturer or installer to arrange for repair. Please note that a
small fee may apply for repair services not covered under warranty.
SYSTEM WIRING
This system should be permanently powered via the ventilation fan.
Both fans are fitted with a power plug; if there are no power points available for the fans
these should be installed by a registered electrician. The wall controller is connected via a
network cable; as this cable is low-voltage it does not need to be wired by an electrician.
SYSTEM OPERATION
Before installing the system, it is important to understand how it works. The fans are
controlled by internal electronics and sensors, and the system operation mode can be
adjusted using the wall controller provided. Refer to the wall controller manual for more
detailed instructions on controller operation.
This system is designed to not be turned off, in order to provide constant ventilation to the
house and as such maintain a healthy and comfortable living environment. Using 2 fans
together allows the system to provide low-level ventilation even while heat transfer is active.
Ventilation Mode Operation
In ventilation mode the heat transfer fan is turned off. The damper is opened, and the
ventilation fan supplies fresh air to all living areas. The back-draft shutter on the heat
transfer fan stops air from going back through the heat transfer inlet grille instead of the
bedrooms.
The ventilation fan is constantly monitoring the incoming air quality and will vary its speed
between very low and very high rates (10 - 100%) depending on air quality and the selected
ventilation rate to maintain a comfortable and moisture-free indoor environment. This is
how the ventilation fan is capable of ventilating at very low rates while still bringing in
enough fresh air into the house in situations where other systems would simply switch off.
Heat Transfer Mode Operation
In heat transfer mode, the damper closes and the ventilation fan runs at the low ventilation
rate, providing fresh air to the heat source room, as well as any other living areas connected
to the ventilation side only. The air in the heat source room is heated, and then distributed
to the rest of the house via the heat transfer fan.
The heat transfer fan first runs at a trickle speed, in order to sense the air temperature going
through the fan. Once the room heats up and there is excess heat available to be
transferred, the heat transfer fan will speed up and start the heat transfer process, adjusting
its speed based on how much heat is available.
When the heat source is no longer providing heat (e.g. fire has died down), the fan will start
slowing down, continuing to transfer any remaining heat in the room. Once no more heat is
left to be transferred, the fan will slow down again to continue running at a trickle speed -
until the room heats up once again and heat transfer starts again.

small fee may apply for repair services not covered under warranty.
SYSTEM WIRING
This system should be permanently powered via the ventilation fan.
Both fans are fitted with a power plug; if there are no power points available for the fans
these should be installed by a registered electrician. The wall controller is connected via a
network cable; as this cable is low-voltage it does not need to be wired by an electrician.
SYSTEM OPERATION
Before installing the system, it is important to understand how it works. The fans are
controlled by internal electronics and sensors, and the system operation mode can be
adjusted using the wall controller provided. Refer to the wall controller manual for more
detailed instructions on controller operation.
This system is designed to not be turned off, in order to provide constant ventilation to the
house and as such maintain a healthy and comfortable living environment. Using 2 fans
together allows the system to provide low-level ventilation even while heat transfer is active.
Ventilation Mode Operation
In ventilation mode the heat transfer fan is turned off. The damper is opened, and the
ventilation fan supplies fresh air to all living areas. The back-draft shutter on the heat
transfer fan stops air from going back through the heat transfer inlet grille instead of the
bedrooms.
The ventilation fan is constantly monitoring the incoming air quality and will vary its speed
between very low and very high rates (10 - 100%) depending on air quality and the selected
ventilation rate to maintain a comfortable and moisture-free indoor environment. This is
how the ventilation fan is capable of ventilating at very low rates while still bringing in
enough fresh air into the house in situations where other systems would simply switch off.
Heat Transfer Mode Operation
In heat transfer mode, the damper closes and the ventilation fan runs at the low ventilation
rate, providing fresh air to the heat source room, as well as any other living areas connected
to the ventilation side only. The air in the heat source room is heated, and then distributed
to the rest of the house via the heat transfer fan.
The heat transfer fan first runs at a trickle speed, in order to sense the air temperature going
through the fan. Once the room heats up and there is excess heat available to be
transferred, the heat transfer fan will speed up and start the heat transfer process, adjusting
its speed based on how much heat is available.
When the heat source is no longer providing heat (e.g. fire has died down), the fan will start
slowing down, continuing to transfer any remaining heat in the room. Once no more heat is
left to be transferred, the fan will slow down again to continue running at a trickle speed -
until the room heats up once again and heat transfer starts again.

If the ventilation system will be taking air from outside or the fan or air inlet is installed in
external walls, care must be taken to avoid the backflow of gases into the system from gas
califonts, open gas flues, or other open-fire appliances.
Acoustic ducting is provided for the reduction of fan motor noise. Connect 1-1.5m of acoustic
ducting to the outlet of each fan, and 2-3m of acoustic ducting to the inlet side of the heat
transfer fan (between the inlet grille and fan). Ensure both the inner ducting and outer
sleeve are fully taped onto the fan, and the outer sleeve of the acoustic ducting is without
tears or holes.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.
Take care not to place the heat transfer inlet grille too close (within 1.5m) to the heat source,
as the air generated can exceed the temperatures that the fan is designed to operate under.
If the intake air is too hot the fan may shut down or be damaged. We recommend placing
the heat transfer inlet grille 3-6m away from the heat source where possible.

Notes about installation of acoustic
and insulated ducting
When installing acoustic ducting, it is
essential to ensure both the inner duct and
the outer sleeve are taped firmly. Acoustic
ducting can be identified by the many
small holes in the inner duct, which are
missing in insulated ducting.
When installing insulated ducting, you
must tape the inner duct, and it is
recommended to tape the outer sleeve
where possible (this generally does not
include the diffusers).

SYSTEM WIRING
This system should be permanently powered via the ventilation fan.
Both fans are fitted with a power plug; if there are no power points available for the fans
these should be installed by a registered electrician. The wall controller is connected via a
network cable; as this cable is low-voltage it does not need to be wired by an electrician.
SYSTEM OPERATION
Before installing the system, it is important to understand how it works. The fans are
controlled by internal electronics and sensors, and the system operation mode can be
adjusted using the wall controller provided. Refer to the wall controller manual for more
detailed instructions on controller operation.
This system is designed to not be turned off, in order to provide constant ventilation to the
house and as such maintain a healthy and comfortable living environment. Using 2 fans
together allows the system to provide low-level ventilation even while heat transfer is active.
Ventilation Mode Operation
In ventilation mode the heat transfer fan is turned off. The damper is opened, and the
ventilation fan supplies fresh air to all living areas. The back-draft shutter on the heat
transfer fan stops air from going back through the heat transfer inlet grille instead of the
bedrooms.
The ventilation fan is constantly monitoring the incoming air quality and will vary its speed
between very low and very high rates (10 - 100%) depending on air quality and the selected
ventilation rate to maintain a comfortable and moisture-free indoor environment. This is
how the ventilation fan is capable of ventilating at very low rates while still bringing in
enough fresh air into the house in situations where other systems would simply switch off.
Heat Transfer Mode Operation
In heat transfer mode, the damper closes and the ventilation fan runs at the low ventilation
rate, providing fresh air to the heat source room, as well as any other living areas connected
to the ventilation side only. The air in the heat source room is heated, and then distributed
to the rest of the house via the heat transfer fan.
The heat transfer fan first runs at a trickle speed, in order to sense the air temperature going
through the fan. Once the room heats up and there is excess heat available to be
transferred, the heat transfer fan will speed up and start the heat transfer process, adjusting
its speed based on how much heat is available.
When the heat source is no longer providing heat (e.g. fire has died down), the fan will start
slowing down, continuing to transfer any remaining heat in the room. Once no more heat is
left to be transferred, the fan will slow down again to continue running at a trickle speed -
until the room heats up once again and heat transfer starts again.

Installation Manual
EVOAQ Ventilation with Heat Transfer Upgrade
Thank you for your purchase of our company’s product. It has been manufactured following
current technical safety regulations and is in compliance with AS/NZ60335 standard.
Please read this instruction booklet carefully before installing or starting up the
product.
It contains important information on personal and user safety measures to be followed while
installing, using, and carrying out maintenance work on the equipment. Once the product
has been installed, please hand this booklet to the end user.
The fans and electronics included with this system are designed as simply plug in
and go while requiring very little user intervention.
The system includes 2 fans, one for ventilation and one for heat transfer. Both fans contain
smart in-built electronics which are constantly monitoring temperature and humidity levels
of the air flowing through the fans. They use this information as well the the settings from
the wall controller to determine what speed to run at, varying their speed between very low-
and very high rates (10 - 100%) as required.
In ventilation mode, the system is designed to supply fresh air to all living areas in the house
at a rate at which the thermal comfort of the house is not affected by the ventilation system.
The heat transfer fan is turned off in this mode.
In heat transfer mode, the heat transfer fan takes excess heat from the heat source room
and redistributes it to the bedrooms. In this mode the ventilation fan continues to provide
fresh air to the heat source room, which is distributed throughout the rest of the house by
the heat transfer fan.
The heat transfer fan is designed to continue transferring heat at low levels even while the
heat source room is cooling down (e.g. at night when everyone has gone to bed) and as long
as there is still some lingering heat that the bedrooms may benefit from. Maintaining correct
ventilation even while heat transfer is active is important in order to prevent condensation
issues and energy losses and to allow you to enjoy a healthier indoor environment.
INSTALLATION OVERVIEW
Before commencing installation, select suitable places for the fans and filter box to be
installed in the ceiling cavity. It is recommended to place the filter and ventilation fan near
the manhole for easy access when carrying out maintenance to the system. Place the filter
before the fan to protect the fan from dust and dirt buildup. Place the heat transfer fan close
to the manhole if possible, and if not possible ensure it is placed in a location that is easily
accessible for servicing.
Suspend the fans from the ceiling framing with the chain and cable ties provided in order to
minimise the sound levels resonating through the ceiling framing.
If the ventilation system will be taking air from outside or the fan or air inlet is installed in
external walls, care must be taken to avoid the backflow of gases into the system from gas
califonts, open gas flues, or other open-fire appliances.
Acoustic ducting is provided for the reduction of fan motor noise. Connect 1-1.5m of acoustic
ducting to the outlet of each fan, and 2-3m of acoustic ducting to the inlet side of the heat
transfer fan (between the inlet grille and fan). Ensure both the inner ducting and outer
sleeve are fully taped onto the fan, and the outer sleeve of the acoustic ducting is without
tears or holes.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.
Take care not to place the heat transfer inlet grille too close (within 1.5m) to the heat source,
as the air generated can exceed the temperatures that the fan is designed to operate under.
If the intake air is too hot the fan may shut down or be damaged. We recommend placing
the heat transfer inlet grille 3-6m away from the heat source where possible.
Please note:
The inlet of the fan unit is on the side of the fan blades, the side that is not obstructed by
the fan frame. There are also arrows on the unit and rating label showing airflow direction.
Please be aware that the system is designed for air to flow from the filter box, through the
ventilation fan, and to the rest of the house on the ventilation side, and for air to flow from
the inlet grille, through the heat transfer fan, and into the bedrooms on the heat transfer
side. Ensure the fans are oriented correctly for this during installation.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.
Some simple rules to apply to ensure the best possible results:
