Product Description
Mechanical Ventilation/Heat Recovery (MVHR). This heat recovery unit is designed for the energy efficient
ventilation of houses and similar dwellings, conforming to the latest requirements of the Building Regulations
document F 2010.
The unit is designed for continuous 24-hour extract ventilation of stale moist air from bathrooms, toilets, utility
rooms and kitchens. As the stale air is extracted, a heat exchanger within the unit transfers up to 93% of the
extract air’s heat, into the supply air entering the bedrooms and lounge. This provides significant energy
recovery, reducing household heat costs, and providing the optimum comfort conditions.
In addition, some models will have features that maintain a constant airflow independent of the blocked filters.

Vertical Discharge Condensate Installation
Note
A trap must be fitted between the condensate drain of the unit and the rest of the waste system.
A waterless trap is recommended, as they are not susceptible to drying out during warmer periods
when no condensate is formed. An example of a suitable waterless trap is the Osma HepVo
waterless trap.
If a conventional trap is used, a trap with a minimum water seal of 60mm must be selected.
The condensate outlet is compatible with standard 22 mm plastic solvent weld fittings and 32mm threaded
waste pipe fittings. Wastepipes must have a 3-degree minimum angle to allow the water to drain away from
the unit naturally.
In areas where freezing weather conditions occur, outlet pipes must be insulated to avoid blockage by ice,
which may cause damage to the unit and surroundings.
This guide shows a Right-Hand configuration for illustration.
If the unit is configured as Left Hand, then the condensate drain should be installed on the left with
the blanking cap on the right.
22mm waste pipe
Fit a waterless trap, or a conventional trap
with a water seal of at least 60mm, close
to the unit.
An adaptor can be used to adapt from
32mm to 22mm connections.
Fit the blanking cap supplied with the unit
to the appropriate side, depending on the
handing, see page 4. Ensure the sealing
gasket is fitted inside the blanking cap.
32mm waste pipe (recommended)
Fit a waterless trap, or a conventional trap
with a water seal of at least 60mm, close to
the unit.
Fit the blanking cap supplied with the unit
to the appropriate side of the unit,
depending on the handing of the unit, see
page 4. Ensure the sealing gasket is fitted
inside the blanking cap.
