Product Description
The Vent-Axia Integra Plus EC Mechanical Ventilation/Heat Recovery (MVHR) is heat recovery unit
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 exhaust ventilation of stale moist air from bathrooms, toilets and
kitchens. As the stale air is extracted, a heat exchanger within the unit transfers up to 70% of the heat and
transfers it into the supply air entering the bedrooms and lounge.

When taking delivery of the unit, check the items delivered against the enclosed delivery note. Inspect the unit
for damage in transit. If in doubt, contact Customer Services. Each box contains a Integra Plus EC MVHR unit,
Remote Boost Switch and an accessory pack containing condensate drain link pipes, clips, energy rating labels
and product documentation.
Lift and Move the Unit Safely
On page 6 check the weight of the unit that you are installing.
Always use appropriate lifting techniques and appliances when moving heavy equipment.
Check Site Requirements and Safety Notices
Check that the physical and environmental conditions for the site meet, or exceed, the requirements detailed in
the table on page 6.
Read and observe the safety notices listed in Warnings and Safety Information on page 2.
Unit Installation
The Integra Plus EC unit is typically installed on a wall in a utility room, storage cupboard, roof void, or similar.
The wall should have sufficient strength to support the unit.
Take into consideration the position of the electrical services and the condensate drain.
Ensure there is an adequate access for installation, operation and maintenance.
It is recommended that a local isolation switch is installed within 1m of the unit to facilitate future maintenance.
The unit can be mounted on a horizontal or vertical face, care should be taken to ensure the unit is angled
towards the condensate drain.

To mount the unit on joists:
Place the unit on a suitable platform across joists and attach the appropriate cabling, drainage and ductwork to the unit, with the
Vent-Axia badge facing up. For optimum performance, ensure the ductwork does not turn 90° directly off the spigots. The unit
should, for optimum drainage, be tilted by 3°- 5° towards the drain side. See Fig. 3a.
Ceiling mounted:.
Invert the unit with the Vent-Axia logo facing down and attach the unit securely to the rafters. For optimum performance, ensure
the ductwork does not turn 90° directly off the spigots. The unit should, for optimum drainage, be tilted 3°- 5° towards the drain
side. See Fig. 3b.
Please note - the location and position of installation for the unit must be decided before any drainage knockouts are removed, as
they cannot be refitted.
5. Having decided upon a location and position remove the knock out for the condensate drain, this must be at the lowest point.
Connect the drain of the ventilation unit to the drainage system using suitable ‘U’-bends (see fig 4).
6. Install suitable internal and external grilles/ terminals and connect them to the ventilation unit using suitable 150mm ducting. If
flexible ducting is used, it should be stretched in order to obtain the best performance.
