General Information

To maintain a healthy indoor environment, closely controlled ventilation is essential. There are

many pollutants that will affect the indoor air quality: human body waste products in the shape of

CO2, dead skin, perspiration and moisture. Add to this the waste products of cooking (cooking

smells), showering (moisture), gases from building materials and the waste products of pets.

Without proper ventilation this would be the perfect environment for the growth of mould,

subsequent damage to the decoration and fabric of a home and to the health of its occupants.

The Heat Recovery unit is fitted with two, low energy EC fans with a constant (100% adjustable) air

volume.

The exhaust fan ensures that warm, damp and polluted air as near as possible to the source is

extracted. The exhausted air has to be replaced with fresh air, so the heat recovery unit not only

has an exhaust fan, but is also fitted with a supply fan and air filters.

The supply air, which in winter is colder than the inside air, is heated in the heat recovery unit using

the heat of the exhaust air by means of the heat exchanger. This heat exchanger has a maximum

efficiency of 91%, so a minimum loss of heat takes place and the supply air temperature enters the

home at a comfortable level.

In exceptionally cold weather or winter conditions it is possible that the exchanger may freeze due

to sub-zero, cold incoming air. Therefore the unit must be sited in a frost-free location.

Alternatively, an in-duct heater may be used to protect the heat exchanger from freezing.

The filters in the unit ensure that the fresh supply air is clean as it enters the home. Also, the

extract air from the property is filtered to protect the heat exchanger from unwanted contamination.

These filters must be inspected regularly, initially every month, and cleaned. Each property will

contaminate the filters at a different rate. The filters should be replaced annually or after a

maximum of two cleaning cycles. Regular filter maintenance will ensure the integrity and

performance of the unit.

The unit’s condensate drain must be installed and connected to the household drainage system

and must be insulated if installed outside the insulated envelope of the building

If the ductwork passes through an unheated area (loft or similar location), it must be insulated with

an insulation material that complies with the latest Building Regulations.

DO NOT switch off the unit – it is designed to run continuously. If the unit is switched off,

indoor pollutants and moisture levels may increase which could endanger your health or

damage your home.

In the event of a power failure or the unit being turned off, restart the unit at High Speed.

This MVHR unit has a soft start.

It is important to follow the advice in this user manual and correctly maintain the system to

ensure a healthy indoor environment.

Installation Instructions

IMPORTANT�

Be sure to have read and understood

SAFETY AND RECOMMENDATIONS

• All wiring must comply with BuildingRegulations and the current I.E.E. Wiring Regulations (BS7671) or the equivalent standards for your country. The final installation should be examined and tested by a qualified electrician. �

Precautions must be taken to avoid the back-flow of gases into the dwelling from the open flue of gas or other fuel-burning appliances. �

Make sure the mains supply complies with the rating label for voltage, frequency and phase.

these instructions before beginning theinstallation process.

PRE-INSTALLATION CHECK LIST�

Make sure that the unit can physically fit in to the desired location. �

The Duplexvent unit should be situated so that access for maintenance or replacement of parts and filters is possible.

The Duplexvent unit is suitable for conventional rigid ducting or low energy radial duct system – Airflow Development Airflex Pro system. If using conventional ducting ensure duct runs are as short as possible, having the most direct route and using as few bends as possible. This is to reduce system pressure.

•

•

• Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision. �

If any cables are damaged they must be

replaced by the manufacturer, its service

agent or similarly qualified persons

Frost Protection

When the cell temperature in the unit falls below 3ºC the unit automatically warms the cell with extracted air to prevent the formation of frost.

Boost - Switched Live

The unit comes with Switched Live asstandard. It is an automatic function, sending the unit to boost when the bathroom or kitchen light is on, or boost switch is activated.

Summer Bypass

The summer bypass helps reduce the air temperature coming into the dwelling during the summer months. It is an automatic function and operates when the supply air temperature to the property is above 25ºC.

Installation Instructions

FIRST FIX - Installing ductwork and electrical supply

Important note: This unit is for wall or floor mount only. Ceiling mounting unit are configured differently and should be ordered separately. �

1. Locate external terminations (supply and extract) in accordance with the latest addition of the Domestic Ventilation Compliance Guide.

�

2. Ductwork from the unit is Ø125mm dia. - maximise duct size where possible. Make sure that the ductwork is insulated in unheated spaces. Minimise flexible duct.

�

3. Locate the mains supply within 1m of the location of unit. The position of the electrical power supply or unit (a fused switched isolator) must not be mounted above or closer than 1m to a cooker where it could be affected by excessive heat or moisture.

�

4. Make sure that there is room for the MVHR unit. The unit is designed to be wall mounted. It can also be floor mounted with an additional kit. Part number 90000558

�

5. Also make sure that there is a free space at the front of the appliance for cleaning the filter and carrying out maintenance on the appliance.

Ducting ConfigurationSee page 11-15 for duct connectionsto the unit/air flow directions

Installed example, RH unit shown.

A – No exhaust within 2m of air inletB – Inlet duct from atmosphere C – Outlet duct to atmosphere D – MVHR E – Ducts to and from property F – Condense Drain

�

Note: Important – if installed in a loft space the area should be within the insulated

envelope to maintain optimum performance
