aircycle 1.1/1.2 – In-built Control & SB Last Updated 02-01-13 age 3 of 14
1.0 Introduction
The Brookvent aircycle 1.1/1.2 is an extremely compact and highly efficient Mechanical Heat
Recovery Ventilation (MHRV) system, specifically designed smaller dwellings with restricted space.
The system should be run continuously 24 hours a day, and should only be disconnected by a
competent person during service or maintenance.
Heat Recovery ventilation works best in new homes, which are extremely airtight and have high
efficiency ratings. These dwellings require a high level of fresh air to ensure a healthy living
environment.
The system works by drawing stale air from ‘wet rooms’ such as Bathrooms, WC’s and Kitchens,
recovering up to 90% of the heat from this air using a highly efficient heat exchanger, before
expelling the waste air outside the home. At the same time, fresh air is drawn into the home,
filtered and warmed by the recovered heat and supplied into the ‘habitable rooms’ such as
bedrooms, dining rooms and living rooms.

2.0 Safety
The following information must be read carefully to ensure safe installation and operation of the
Brookvent MHRV system.
2.1 General Safety
• Do not use this appliance for functions other than those described in this booklet.
• Never touch the appliance with wet hands.
• The unit is only suitable for 230 VAC/50Hz electric mains.
• Never modify the fan or electronics, all repairs must be conducted by Brookvent.
• Never connect the power if electronics cover is not fitted.
• Do not store inflammable products in the neighbourhood of the unit.
2.2 Responsibility of the Installer
• Correct Installation, balancing and commissioning of the MHRV unit.
• Record measured air flow volumes on each of the valves at High and Low rate.
• Compliance to requirements and local additional rules.
• Explanation of the ventilation system to the user.
• Warning for the user, to check or replace the air filters on time.
• All the above, as set out in the latest edition of the Domestic Ventilation Compliance Guide
and the SA Appendix Q – installation Guide and Checklist.
2.3 Responsibility of the Occupant
• Replacement of the filters as per the recommended interval.
• Cleaning the valves in the rooms regularly to prevent blockage.
• To ensure that the system is functioning properly on a regular basis
• To use manual boost switches (where provided) to prevent build-up of pollutants or mould
growth.
IM ORTANT: Dirty or clogged filters may cause inadequate ventilation in the home which may lead
to health issues. It is important that the filters are changed at least once per year or as required.
In new build properties it may be prudent to check/ change your filters after the first 3 months of
occupancy depending on the amount of residual ‘building dust’ present within the property.

4.0 Installation
It is important that the full installation of this system is carried out by competent persons, including
all electrical works and connections being completed by a qualified electrician.
The MVHR unit is designed to be installed indoors, within an attic, storage cupboard, or void space,
away from exposure to frost, water, or intense heat.
A clear access space is required around the unit; this will ensure ease of installation relating to
ductwork, wiring, and the connection of the condensate drain. It is important that filters to the
system can also be accessed for replacement.
4.1 Mounting
The aircycle 1.1/1.2 Ws is designed for Wall Mounting only. The unit should be attached the to the
wall as shown using the wall bracket provided, please ensure the mounting surface can safely bear
the load of the unit using suitable screw fixings.
One bracket should be secured to the back of the unit as shown in Fig. 1, the second bracket should
be secured to the mounting surface as shown in Fig. 2. lease ensure the brackets are level.
The unit can then be set onto the mounting surface with the lip of each bracket intersecting as
shown in Fig. 3
Fig. 1
Fig. 2

4.2 uctwork and Connections
To comply with SA Appendix Q, and to facilitate the air flow performance, all ducting used should
be rigid. If flexible ducting is required, it should be kept to an absolute minimum of 300mm and kept
taut as per the Domestic Compliance Guide ( art F: Eng and Wales 2010)
The spigots on the Brookvent aircycle 1.1/1.2 systems are suitable for connection to 125mm
diameter round pipe.
The label on top of the unit clearly identifies which spigot should be connected to which ducting
route with the dwelling. This is also shown clearly within this manual.
To assist the performance of this HRV unit, it is recommended that 125mm diameter round pipe is
used (where possible) to connect to the spigots and continue throughout the dwelling, this will assist
in keeping pressure losses to a minimum.
Where it is not possible to continue throughout the dwelling in rigid 125mm diameter round pipe
due to the void spaces available, a conversion to rigid 204mm x 60mm flat rectangular ducting is
recommended. It is recommended that the number of bends in the ducting system is kept to a
minimum.
Each of the external roof terminals / wall terminals must be the equivalent to the open area of
125mm diameter round pipe.
To facilitate air circulation within the dwelling there must be a minimum of 10mm undercut on each
of the doors (to the finished floor) within the dwelling (or grills placed at low level on the doors).
Extract air valves should be placed in all wet rooms (kitchen, utility, en-suite, etc.) and should be
sited, where possible, close to the main source of humidity/ pollutant.
Fresh supply air valves should be placed in all habitable rooms (bedroom, sitting room, dining room,
etc.).
Duct designs/ layouts should always be adhered to if provided.
Important: The Domestic Compliance Guide: Eng and Wales 2010 should be adhered to as part of
the installation process.

4.3 Connection of Condensate rain
HRV systems generate considerable amounts of moisture due to their high Heat Recovery Efficiency;
this moisture must be drained from the system.
The aircycle 1.1/1.2 is supplied complete with a centralised drainage connection on the bottom of
the unit.
The condensate drain should incorporate a “ Trap” or equivalent, as shown, before being
discharged into the waste drainage system of the dwelling. The “ Trap” should be filled creating an
immediate seal upon installation.
It is imperative that there is a gravitational fall from the unit to the discharge point ensuring that the
water drains from the unit. A minimum fall of 5 Degrees should be ensured throughout as shown.
Drainage piping/ connections should be insulated if located in cold roof spaces.
