Product Description
Sentinel Kinetic MVHR with Cooker Hood
The Vent-Axia Sentinel Kinetic Mechanical Ventilation Heat Recovery (MVHR) unit is a heat recovery unit
with a Cooker Hood designed for the energy efficient ventilation of houses and similar dwellings, conforming to
the latest requirements of the Building Regulations document F 2010.
In case of a fire or severe overheating on the hob, the unit is fitted with an intumescent fire damper to close the
duct as required by BRE Digest 398 and a thermal fuse to switch off the electrical power.
The unit is designed to be mounted in the kitchen above a cooker hob in a standard cupboard space for
continuous 24-hour exhaust ventilation of stale moist air from bathrooms, toilets and kitchens. The unit should
be switched to boost mode by extending the cooker hood during cooking, or by use of any of the standard
switches or sensors. As the stale air is extracted, a heat exchanger within the unit retains up to 90% of the heat
and transfers it to the supply air entering the bedrooms and lounge.

Models
447003, 447004, 447005, 447006 - Sentinel Kinetic with Cooker Hood, SELV transformer and summer
bypass. An internal damper is activated when the outside temperature is equal to, or greater than, the pre-
set ‘Comfort Temperature’ (adjustable between 16 and 30°C). The damper opens allowing cooler fresh air
to bypass the Heat Recovery Cell and reduce the internal temperature to the pre-set ‘Comfort
Temperature’. When the inside air temperature reaches the pre set ‘Comfort Temperature’ the bypass
damper closes. (See page 10 within the Operation & Monitoring leaflet for further information). Note that
when the cooker hood is extended the heat recovery cell bypass opens ensuring that grease and other
contaminants from cooking do not reduce its efficiency during normal use.
Accessories
441865 - Wireless enable kit (consists of wireless receiver and one wireless switch).
437827 - Additional wireless switch (up to four may be connected).
443131 –Wired remote control.
A range of sensors can be used to manage system demand and control the ventilation rate. These include an
internal humidity sensor, humidity sensors for independent mounting in rooms, wireless receiver and wireless
boost switches, CO2sensor, manual switches and pull cords. For these alternative control options, see
www.vent-axia.com
User Information
Operation of Cooker Hood
The unit is operated in boost mode when the telescopic hood is pulled out. Close it to return the unit to its
Normal Flow Rate.
Important Note:
Do not hold on to or place any object on telescopic hood whilst it is open, since this can cause damage to its
functioning component parts
Operation of Cooker Hood Light
Access can be gained to the light switch when the telescopic hood is opened. The light may be left on with the
hood closed if required. However, make sure you switch it off when you have finished using it.

Appendix A: Options and Accessories
Humidistats
An optional internal humidistat is available as an accessory. This adjusts the fan speed proportionally depending
on the temperature and relative humidity levels in the extracted air whilst avoiding nuisance tripping at night time
when temperatures drop and relative humidity naturally rises. The unit does not just look for relative humidity
levels above a set point, which can be unreliable in products that extract from multiple rooms, but it also looks
for a rapid increase in relative humidity typically generated by such activities as showering or cooking.
Note:- This is fitted to models 477003, 477004, 477005 & 477006 as standard.
For further details on options and accessories, refer to Sentinel Kinetic installation & commissioning
documentation.
