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, 446756, 446757, 446758, 446759 – 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 preset ‘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.

Table 1: Spares

Troubleshooting

See the Sentinel Kinetic documentation.

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 446756, 446757, 446758 & 446759 as standard.

For further details on options and accessories, refer to Sentinel Kinetic installation & commissioning documentation.
