Product Description
Sentinel Kinetic MVHR Installation & Commissioning 4
Product Description
Sentinel Kinetic 200Z, 200ZH & 300Z, 300ZH
The Vent-Axia Sentinel Kinetic Mechanical Ventilation / Heat Recovery (MVHR) heat recovery unit is
designed for the energy efficient ventilation of houses and similar dwellings, conforming to the latest
requirements of the Building Regulations document F 2010.
The unit is designed for continuous 24 hour exhaust ventilation of stale moist air from bathrooms, toilets and
kitchens. As the stale air is extracted, a heat exchanger within the unit transfers the heat into the supply air
entering the bedrooms and lounge.
Sentinel Kinetic 200Z, 200ZH & 300Z, 300ZH Summer By Pass.
The Sentinel Kinetic is fitted with a Summer By Pass (SBP) and will provide energy-free heating and energy-free
cooling when the house temperature and ambient temperature allows.
If the room is warmer than the set (shown as "indoor") temperature (i.e. you need the room to be cooler) and the
outdoor air is cooler than the actual room temperature (i.e. the outdoor air could cool your room) then the SBP will
open and the unit will supply cooler air to your room.
If the room is cooler than the set ("indoor") temperature (i.e. you need the room heating) and the outdoor air is
warmer than the actual room temperature (i.e. the outdoor air could heat your room) then the SBP will open and
the unit will supply warmer air to your room.
Note that the above only applies whilst the outdoor air temperature is above 14C (adjustable) in order to prevent
cold draughts.
The set ("indoor") temperature should be set 2 or 3 degrees higher than the central heating thermostat and 2 or 3
degrees below any air conditioning thermostat if fitted. This will prevent any clash between the separate systems

Technical Specification & Installation
Sentinel Kinetic MVHR Installation & Commissioning 6
Overview
The following instructions are intended to help prevent potential hazards and installation should only be carried out
by a qualified electrician and installer.
NOTE: we advise installers to fix all mains, sensor wiring and wired remote control along with any internal
accessories prior to fixing the MVHR unit in position.
Before Installation of the Unit
Inspect the Unit
When taking delivery of the unit, check the items delivered against the enclosed delivery note. Inspect the unit for
damage in transit. If in doubt, contact Customer Services. Each box contains a Kinetic unit and ceiling mounting
brackets and product documentation.
Lift and Move the Unit Safely
Check the weight of the unit that you are installing. 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.
Unit Installation
The unit MUST always be mounted horizontally. Do not use this unit as a support for any other equipment.
The ceiling 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 disconnection mains and sensor terminal box is installed within 1m of the unit to
facilitate future maintenance.

Ceiling Mounting
Fix the 2 Brackets to the ceiling, the fixings must be suitable for the surface type intended (concrete,
wood) they must also be compatible for the units weight , 200 Z & ZH = 26Kg - 300Z & 300ZH = 38Kg

Installation of Unit Brackets
Stage 1: Drill the holes according to the guide on the
previous page; make sure the holes you drill enable the
brackets to be moved apart within the guide holes on the
bracket.
Stage 2: Place each of the bolts into position and do not
fully tighten. Leave approximately “a half turn” loose on
each of the fixings. This will allow each bracket to be
moveable until final fitting of the unit and makes any
adjustments easier while installing the unit in position.
Stage 3: The brackets are in their approximate location
and the unit can now be raised into position.
Once the unit is in its located position, the brackets can
be moved and secured.
Stage 4: Finally, with the unit secure you can now fix the
security fixing (as pictured right).
Once secured you may proceed with the rest of the
installation.

Technical Specification & Installation
Sentinel Kinetic MVHR Installation & Commissioning 9
Connecting the condensate drain
There are two ways of connecting the condensate drain
of the unit, which is dependent on the installation
scenario.
Install A: U-Trap configuration (22mm Waste)
Using a 22mm (dia) fitting the U-Trap is formed of four
90(deg) elbow bends and 22mm standard waste pipe to
connect between the elbows. A further 22mm (dia)
waste pipe then connects to the unit’s drainage via an
inline 22mm (dia) coupler.
Please note you must ensure that there is a minimum of
a 3(deg) downward angle to allow water to drain away
from the unit naturally.
Install B: In-line configuration (32mm/22mm waste)
For installations in a ceiling void where it is too shallow
for a traditional U-Trap configuration. Our
recommendation is to use a HepVO inline waste valve
and Tundish Adaptor kit (Part number: BV1/21-32mm).
The Tundish adaptor will allow a connection to the
existing 22mm dia condensate leaving the unit via an
inline 22mm coupler.
However the opposite exhaust end of the HepV0 valve
will require a 32mm Waste pipe connection to exhaust
waste from the property.
All mentioned parts are available from your nearest
Plumbing trade centre.
Please Note: In areas where cold conditions inc frost
are possible, outlet pipes must be insulated to avoid
blockage and potentional damage to the unit and
surroundings. 32 mm straight waste

Attaching the ducting
1. Always use a short piece of flexible ducting 100-150mm long, extended to its full length when connecting to
ductwork.
2. Securely connect this ducting to the spigots using worm-drive clips or cable ties and duct tape.
3. Insulate any ducting passing through an unheated space to prevent any heat losses and surface condensation.

1. The Wired remote Control uses a 15 metre long cable to connect to the unit, it can be permanently mounted in a
living space for the end user or used for commissioning the unit.
2. Fit the 15 metre Remote Control cable plug into the cable socket fitted to the Heat Recovery Unit.
3. Connect the cable assembly to the Remote Control terminal block (the terminal block is colour coded to match
the individual coloured cables and mount onto a single gang recessed wall box with the 2 screws provided.

Connect Switches and Sensors
The unit can be switched to boost by a variety of methods:
Applying 240 V to the LS input.
Switching across 1 of 5 pairs of switch terminals.
Applying between 0 and 10 V as a proportional input to two input terminals.
In addition, fitting a Vent-Wise Accessory to the unit means that switch terminals 1-3 can be connected to be
switched by a current detector (for example, detecting a hob being switched on) or a temperature sensor (for
example, detecting the flow of hot water). Terminal 4 can be used in conjunction with a momentary switch or
switches.
Connect any switches or sensors required to control the unit by connecting to the terminal connectors at the bottom
of the control unit as shown below and in Table 1. If necessary contact Vent-Axia regarding the wiring and fixing of
accessories and sensors.
Ensure that you use a grommet or gland to protect against potential water ingress.

WARNINGS
1. MAINS SUPPLY VOLTAGES (220-240 V AC) ARE PRESENT IN THIS EQUIPMENT WHICH MAY CAUSE
DEATH OR SERIOUS INJURY BY ELECTRIC SHOCK. ONLY A QUALIFIED ELECTRICIAN OR INSTALLER
SHOULD CONNECT THE POWER SUPPLY TO THIS UNIT.
2. THIS UNIT MUST BE CORRECTLY EARTHED.
This unit is designed for operation from a single-phase alternating current source (220-240 V AC). A 2 m cable is
connected internally to the unit for connection to a switched fused spur.
To connect the power supply:
1. Ensure the local AC power supply is switched off.
One end of the power cable supplied is already connected to the unit.
Connect the other end of the cable to the switched fused spur.
Use cable clamps and clips to secure the cable, as appropriate.
Connecting a Boost (Light) Switch
A Switched Live (LS) may be used to boost the airflow when a light is turned on, for instance in a bathroom or
kitchen.
Power supplied to the unit via a Switched Fused Spur must be supplied via the same circuit as the LS connecti
