Sentinel Kinetic Range Summer By Pass Models.
The Sentinel Kinetic B, BH, Plus B, Plus BS, S BH, and Plus CVP are 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 14 C (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.

Installation
Overview
The following instructions are intended to help prevent potential hazards and installation should only be carried
out by a qualified electrician and installer. This booklet covers both the Kinetic and Kinetic Plus. The control
systems are identical on all units. There are some differences during the physical installation that the installer
needs to be aware of.
NOTE: we advise installers to fix all mains and sensor wiring along with any internal accessories prior
to fixing the MVHR unit in position, leaving approximately 500 mm tails to allow for internal routing.
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 HR unit and an
accessory pack containing wall brackets, condensate drain link pipe, worm-drive clip, fixings and product
documentation.
Lift and Move the Unit Safely
On page 5 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 on page 5.
Read and observe the safety notices listed in Warnings and Safety Information on page 2.
Unit Installation
The Sentinel Kinetic unit is typically installed on a wall in a kitchen, storage cupboard, roof void, or similar. It will
fit in a 600 mm (external) x 300 mm deep (internal) kitchen wall cupboard.
The Sentinel Kinetic Plus unit is typically installed on a wall in a utility room, storage cupboard, roof void, or
similar.
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 disconnection mains and sensor terminal box is installed within 1m of the unit to
facilitate future maintenance.
The unit MUST always be mounted vertically with ducting exiting vertically or horizontally. Do not use this unit
as a support for any other equipment.
Select Unit Orientation
The unit is supplied from the factory with the condensate exit (and the atmosphere spigots) to the right of the
unit, when viewed from the front. Access is required to the Control Unit on the front of the unit in order to
commission, operate and maintain the unit. If the unit is to be installed as supplied, skip the following section
and go to Vertical Discharge Condensate Installation on page 13.

Sentinel Kinetic MVHR Installation & Commissioning 11
If the orientation of the condensate exit (and the atmosphere spigots) would be better suited on the left of the
unit, the front Control Unit and the rear Cable Inlet Plate can be swapped over to allow the unit to be installed in
the opposite orientation.
Sentinel Kinetic Plus CVP is supplied with condensate drain exit to the right of the unit and cannot be installed in
the opposite orientation (LH).
Installing the Unit in the Opposite Orientation (LH Condensate)
This procedure for opposite orientation applies to all
Sentinel Kinetic range named in this document,
except Kinetic Plus CVP.
Installing the unit in the opposite orientation involves
removing the front cover (and associated Control Unit
Panel), and the rear cover (and associated Cable
Inlet Plate), rotating the unit chassis and covers
through 180 degrees and then re-attaching them.
This moves the condensate drain exit from the right
(rear) corner of the unit to the left (front) corner of the
unit, when viewed from the front (viewing the Control
Unit).
The arrow labels on the top edge of the Covers
should be correctly matched to the arrow labels on
the top of the Case.
