3 Regulations and Safety Instructions
The Xcell 400 MVHRs are tested in accordance with the low-voltage directive 2006/95/EC and EMC directive
2004/108/EC.
This appliance is not intended for use by persons (including children and the infirm) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Ensure that all relevant safety precautions (correct eye protection and protective clothing etc) are taken when
installing, operating and maintaining this MVHR. Observe the safety regulations and warnings contained in this
manual at all times. Failure to do so may result in damage to the unit or personal injury.
This MVHR is intended for connection to fixed wiring. A means for disconnection must be incorporated in the fixed
wiring. Installations and wiring must conform to current IEE Regulations (UK), local or appropriate regulations (other
countries). All installations must be supervised by a qualified electrician. It is the installer‟s responsibility to ensure
that the appropriate building codes of practice are adhered to.
This MVHR must not be installed near to sources of direct heat such as cookers/grills or where ambient temperatures
may exceed 50ºC.
When the MVHR is installed in a room containing a fuel burning appliance, precautions must be taken to avoid the
backflow of gases into the room from the open flue of the fuel burning appliance.
The instructions on periodic cleaning and/or changing of the Filters, the air inlet/outlet valves and the air inlet/outlet
grilles must be strictly observed.
The unit may only be connected to a 220-240V AC power supply.
The following applications / installations are prohibited:
The use of excessive fat-contaminated exhaust air, extracting explosive gases, extracting particle-
contaminated air, extracting adhesive particulate matter.

Connecting extractor hoods in the ventilation system
Servicing of the MVHR may only be carried out by a qualified service technician. Contact details for authorised
servicing by Xpelair approved technicians can be found on the back of this booklet.
4 Application and Planning
4.1 Application
This MVHR is intended for installation in ventilation systems in houses, residential buildings and light commercial
applications e.g. offices and meeting rooms etc. Upon completion of the system, there should be no safety, health or
environmental risks present. The manufacturer of the MVHR assumes no liability for this.
4.2 MVHR operation overview
Using two Fans, each with a filter in separate air paths, the MVHR draws in external air from the outside and exhaust
air from odour-contaminated and moisture-laden rooms (i.e. kitchen, bathroom, WC) in the house. Both of these air
flows are passed through a cross counter flow Heat Exchanger whereby the exhaust air releases heat and the
external air absorbs heat. The air ducts are separated from one another to prevent odour pollution between external
and exhaust air.
Using suitable air ducts and adjustable air inlet valves (separately purchased accessories), the heated external air is
blown into the house and the cooled exhaust air is ducted out of the building.
There are numerous accessories available for manually or automatically controlling the MVHR, see section 6.6.
