INSTALLING THIS UNIT, CALL US ON:
Safety
Read and understand these instructions carefully before
beginning installation. The unit should only be installed by a
competent person.
Electrical Connection
The unit requires a continuous electrical power supply. Connection to
the fixed wiring must be made outside the unit in a suitable location.
The unit must be able to be disconnected from the mains supply
after installation. The unit must be earthed and a suitable isolator
having a minimum contact separation of 3.0mm must be used to
provide isolation for the unit.
The power cable running into the unit must remain the supplied
flexible cable. If the power cable becomes damaged, it must be
replaced by EnviroVent, an authorised service agent for your region/
country, or a similarly qualified person in order to avoid a hazard. Do
not remove or tamper with any electronic components inside the
unit.
All wiring must comply with Building Regulations and the current
IET Wiring Regulations (BS7671 in the UK) or equivalent standards for
other countries. The final installation should be examined and tested
by a qualified electrician.
The unit is considered to be suitable for use in countries having a
warm, damp equable climate. It may also be used in other countries.

Location
Check there is space for the unit in your chosen location including
room for access and future servicing of the unit. The unit must not
affect the operation of open-flue appliances. Consider the external
vent locations in relation to open-flues from appliances e.g. boilers.
You must ensure the external supply grilles are positioned away from
open flues to avoid drawing harmful gases into the property. Consult
your local regulations or a qualified gas engineer.
Users
This unit is not intended for use by persons [including children] with
reduced physical, sensory or mental capabilities or lack of experience
and knowledge, unless they have been given supervision and usage
instruction by a person responsible for their safety. Children should
be supervised to ensure they do not play with the unit. Cleaning and
user maintenance must not be performed by children.

WIRING
The local isolator must be connected to the mains as
part of the fixed wiring. Connect the cores of the power
cable to the matching terminals on the local isolator
(3A fuse spur or similar).
The black switch live core of the mains cable can be
wired to a switch input such as a light switch. When
the switch is turned on, the boost function is engaged.
When the switch is turned off, the unit will return to
normal running mode. In this configuration a triple pole
isolator must be used.

About the energiSava®250
The energiSava®250 is an MVHR unit (Mechanical Ventilation with Heat
Recovery). It is ideal for medium to large sized properties with a kitchen
and up to 5 additional wet rooms. The unit is capable of delivering a
maximum airflow of 280m3/h (78l/s) and a maximum system pressure
in excess of 224Pa.
The unit will help to create a fresh and healthy living environment by
supplying filtered air into a property through supply valves. Moist, stale
air is removed out of the property through extract valves.
The heat exchanger inside the unit transfers waste heat energy from
the extracted air to the supplied air in order to improve the indoor air
quality of the property and reduce heating costs.
When outdoor temperatures are low, the frost protection feature
automatically reduces the supply air flow rate to ensure the heat
exchanger inside the unit does not freeze.
The Intellitrac®humidity tracking function monitors the humidity levels
in the extracted air and will automatically increase the supply and
extract air flow rates when the humidity levels rise. Once the humidity
levels are lower the air flow rates will return to the normal rate.
The automatic, thermal bypass helps to control temperature entering
the home on warmer days.
The energiSava®250 includes a switch live function. When wired
through the lighting switch of a room (such as a bathroom) the unit
will enter boost mode whenever the light is turned on.

Pre - Installation Checklist
• Does the unit fit in the space where it will be installed?
• Is there room to connect ducts to the spigots without tight duct bends?
• Is there room to access and replace the filters after installation?
• Are there any obstructions above or below the locations where the
input and extract valves are to be fitted?
• Is the mounted surface strong enough to support the unit?
• Is the mounting surface level?
• Are there adequate facilities to connect the unit condensate drain to
the internal waste system of the property?

Installation
1. Hold the unit up to the chosen location and check there is space
for ducts, condensate drainage, filter and keypad access.
2. Once you are satisfied with the position, line up the two brackets
using the printed template then secure them to the mounting surface..
Use 10 8gx2.0” screws and 10 plasterboard plugs.
3. Mount the unit onto the brackets ensuring that it is fully supported.
4. Apply the two wing nuts onto the threaded studs then insert the
self-tapping screw into the hole and tighten it. This will ensure the
unit cannot be accidentally knocked off the brackets.

5. Fit the external supply and extract terminations.
6. Fit the supply and extract valves inside the property.
7. Fit the ductwork between the external terminations, the MVHR unit
and the supply and extract valves.
5 6
7Ductwork should be fitted in
accordance with the Domestic
Ventilation Compliance Guide.
(Example RH unit configuration
shown).
Ducts to and from atmosphere and
through unheated spaces need to
be insulated.
All ductwork should be as large
a diameter as possible (min.
125mm) and use rigid duct or a
suitable semi-rigid duct system
such as Envirovent fast track.

9. Make a water-tight connection between the two drainage connectors
on the unit and the waste water system in the property. A suitable non-
return device must be fitted to ensure air and waste water from the
drain system do not flow back up into the unit. The drainage must be
fitted with a minimum 5 degree fall away from the unit.
