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
441483, 441484, 441485, 441486 - Sentinel Kinetic with Cooker Hood and with 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
441838 - Plug-in integral humidity sensor.
441865 - Wireless enable kit (consists of wireless receiver and one wireless switch).
437827 - Additional wireless switch (up to four may be connected).
441780 - Vent-wise accessory pack.
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 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.

Installation
Overview
The following instructions are intended to help prevent potential hazards and should be carried out only by a
qualified electrician and installer.
Before Installing the Unit
Inspect the Unit
When taking delivery of the unit, check the items delivered against the delivery note. Inspect the unit for
damage in transit. If in doubt, contact Customer Services. The Sentinel Kinetic with cooker hood is made up of
two separate boxes. Each box containing the Sentinel Kinetic HR with metal duct assembly should come with
an accessory pack containing wall brackets, condensate drain link pipes, worm-drive clips, fixings and product
documentation. Each box containing the cooker hood should contain an accessory pack consisting of black
protective box for cooker hood socket and plug connection, screws, cable receptors and product documentation.
A template to aid marking out the wall for drilling is printed on the carton.
Lift and Move the Unit Safely
The weight of this unit is 28 kg. 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 Technical Specification on page 6.
Read and observe the safety notices listed in IMPORTANT on page 2.
Unit Installation
READ THE SENTINEL KINETIC INSTALLATION & COMMISSIOING DOCUMENT BEFORE INSTALLING
THIS UNIT. In particular, ensure that any external switches, sensors and electrical connections are made prior
to the unit being mounted on the wall.
The Sentinel Kinetic Cooker Hood is only suitable for installation above a domestic cooker or cooker hob. The
unit with cooker hood must be sited a minimum of 650mm above an electric hob and 750mm above a
gas hob.
It will fit in a 600 mm (external) x 300 mm deep (internal) kitchen wall cupboard space above the hob.
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 adequate access for installation, operation and maintenance.
It is recommended that a local mains and sensor terminal connection box is installed within 1m of the unit to
facilitate future maintenance, rather than wiring these directly to the unit.
The unit MUST always be mounted vertically with ducting exiting vertically. Do not use this unit as a support for
any other equipment.
Select Unit Orientation
The unit may be purchased as left or right hand, where left hand refers to the connections to atmosphere being
on the left side of the unit.
