Product Usage Instructions

Installation

The Sentinel Kinetic FH can be mounted vertically in a roof space or in an appropriate cupboard within the dwelling. If mounted in an unheated area, the ducting and unit must be insulated according to the Domestic Ventilation Compliance Guide. The ducting can be attached to the unit horizontally, vertically, or both.

Noise Reduction

If noise is a critical issue, an Acoustic Enclosure is available to reduce breakout noise, and the Acoustic Top Box will reduce in-duct noise at key frequencies.

Left or Right Hand Installation
The Sentinel Kinetic FH is available for both left (L) and right (R) hand installation.

Spigot Options
The combination of spigot options allows installation in confined locations. If vertical and horizontal connections are required on the same outlet/inlet, additional spigots can be supplied.

Condensate Drain
The condensate drain can be taken out through the back, side, or bottom of the unit. The final condensate connection is made outside the unit using the fittings supplied, which can be completed after installation.

Integral Humidity Sensor
The Sentinel Kinetic FH is equipped with an integral humidity sensor. The sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. It also reacts to small but rapid increases in humidity, ensuring adequate ventilation even for small wet rooms. The night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperatures.

Easy Installation

• The Sentinel Kinetic models can be mounted vertically in a roof space or in an appropriate cupboard within the dwelling. When mounted in an unheated area the ducting and unit must be insulated in accordance with the Domestic Ventilation Compliance Guide. Ducting can be attached to the unit horizontally, vertically or both.
• For scenarios where noise is a critical issue, an Acoustic Enclosure is available to reduce breakout noise and the Acoustic Top Box will reduce in-duct noise at key frequencies.
• Left (L) or right (R) hand installation. Left-hand and right-hand units are available.

Spigot Options

• The combination of spigot options allows installation in confined locations. If vertical and horizontal connection is required on the same outlet/inlet, additional spigots can be supplied.
• The condensate drain can be taken out through the back, side or bottom of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation.

Integral Humidity Sensor

The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The nighttime relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperatures.

Consultant’s Specification

Consultant’s Specification

Operation

• The supply and extract ventilation unit shall be a Sentinel Kinetic as manufactured by Vent-Axia and shall be sized as indicated on the drawings and shall be by the particular specification.
• Supply air to the room shall be pre-heated by the extract air via the integrated composite plastic counterflow heat recovery cell. The Sentinel Kinetic shall automatically vary the ventilation rate via EC/DC motors, as it receives signals from one of the optional interconnected sensors. When a signal is received, the fans shall either vary their speed proportionally or on a trickle and boost principle.
• The unit shall have the facility to commission the supply and extract fans individually via in-built minimum and maximum speed adjustment, or alternative wired remote control unit. The fans themselves shall have independent, infinitely variable speed control.

Unit Specification

• The unit shall be manufactured with an ABS outer case construction, and incorporate a reversible core to allow for left or right-hand mounting.
• The unit shall have a high-efficiency composite plastic counterflow heat exchanger, supply and extract filters, automatic summer bypass, and integral minimum, and maximum infinitely variable speed controls with facia-mounted failure indication. The unit shall have low-energy, high-efficiency EC/DC fan/motor assemblies with sealed for-life bearings. The impellers shall be high-efficiency backward curved centrifugal type.
• The unit shall have a heat exchanger cell with a thermal efficiency of up to 90% when tested to EN 308. This shall be protected by ISO 45% Coarse (G3) grade synthetic filters on supply and extract. Complete with a condensate drip tray and drain connection.
• To reduce breakout noise, the MVHR unit shall be provided with an Acoustic Enclosure of steel construction lined with class ‘0’ acoustic foam. To reduce in-duct noise, the top of the MVHR shall be fitted with an Acoustic Top Box to provide attenuation to the 4 ducts of the unit. This Acoustic Top Box shall be of steel construction lined with acoustic class ‘0’ foam with the MVHR spigots linked to the Top Box via 4 separate attenuated ducts. The acoustic enclosure and top box shall each be independently tested for noise to BS EN 13141-7.
• The MVHR unit shall incorporate an Expanded Polystyrene (EPS) inner chassis with custom motor and impeller mounting features. The inner chassis will assist in reducing noise and act as a large anti-vibration mount avoiding transmission through to the back mounting plate or base of the unit.
• The MVHR unit will be tested to ensure it meets the maximum allowable vibration of no more than 1mm/s, measured on the unit wall fixing points.
• The unit shall be constructed with a removable Core allowing full maintenance access. The removable Core shall provide access to the following:
  • Supply and extract filter
  • Heat exchanger
  • Access to the electrical connections
• Access shall be provided for wiring termination and setup/commissioning. The backlit LCD user interface therein shall be removable for remote mounting if required.
• Units shall be as manufactured by Vent-Axia Ltd.

Acoustically tested to BS EN 13141-7

Standard Controls

• Integral infinitely variable fan speed control on supply and extract
• Integral min/max ventilation control/set point
• Integral BMS interfaces – control and status indication
• Heating interlocks
• 0-10V proportional speed adjustment
• Volt free contacts
• 24V sensor supply

• Switched Live input with adjustable ‘delay-on’ feature
• Fan failure or component failure indicated via individual fault code display
• Running time counter
• Control panel PIN number lock
• Automatic frost protection effective to -20°C
• Tool free filter access
• The unit shall incorporate (‘H’ models) an integral humidity sensor with the following features:
  • Ambient Response; Raises the humidity trigger point as dwelling temperature reduces
  • Rapid Response; Monitors the rate of change in humidity and triggers increased airflow even if the humidity trigger threshold is not reached
  • Proportional Response; Incrementally increases the fan speed to reduce noise and energy consumption
