11. . IntroductionIntroduction
The subject of this installation manual is Futura - ventilation unit with heat and mois ture recoveryFutura - ventilation unit with heat and moisture recovery, which is designed
for controlled ventilation and treatment of the indoor environment of residential premises. The heat recovery unit ensures
recovery of heat and moisture, filters supplied air and helps maintain optimum air humidity. In summer, it provides additional
cooling in the night mode thanks to an integrated automatic bypass.
Before proceeding to the entire installation and commissioning of the heat recovery unit, read this Installation Manual carefully. It
is intended for trained professionals with appropriate qualifications. The Installation Manual contains explanations concerning
basic configuration of the unit, its assembly, installation, settings and maintenance.
Pay attention to all specifications and instructions included in this manual and follow them accordingly. This is the only way of
ensuring proper and safe operation of the heat recovery unit.
This device complies with the Commission Regulation (EU) No 1253/2014 with regard to ecodesign requirements for ventilation
units and Commission Delegated Regulation (EU) No 1254/2014 with regard to energy labelling of residential ventilation units.
ANY CHANGES RESULTING FROM TECHNICAL DEVELOPMENT ARE RESERVED. WE RESERVE THE RIGHT TO CHANGE THE
CONTENTS OF THIS INSTALLATION MANUAL ANYTIME WITHOUT PRIOR NOTICE.

22. . Identification and applicationIdentification and application
The Futura heat recovery unit is HVAC device with heat recovery and an active control of moisture recovery, that is designed for
comfortable and energy-efficient controlled ventilation of family houses. The heat recovery unit provides controlled ventilation of
residential premises with required ventilation volume of: 100 – 350 m3 (3530 - 12360 ft3) for Futura L or 50 - 250 m3 (1766 - 8830
ft3) for Futura M, at the outdoor air temperature range from -19 °C to +45 °C (-2 °F to 113 °F). The unit can be used at the maximum
relative indoor humidity level of 60% measured at 22 °C (72 °F).

The heat recovery unit may only be installed, connected, commissioned and maintained by an authorized service technician
with respective professional qualifications. A service technician is a person with adequate qualification, experience and
knowledge of respective regulations and standards as well as possible risks and dangers.
Conductors connected to the equipment must be laid in such a way so as not to be exposed to mechanical damage and
harmful environmental effects and not interfere with the use of the premises where the unit will be installed.
The unit may be operated only by physically and mentally apt persons that have thoroughly read and understood the
Installation and User Manual. The manuals must be stored in an accessible place.
Do not change or modify the heat recovery unit in any way!

The heat recovery system is equipped with 4 EPP ∅ 150 mm (6 in) flanges. It is necessary to use (intake/exhaust) EPP pipes both
at the air intake from the exterior and the air exhaust to the exterior to prevent the possibility of unwanted condensation inside
the pipes. For indoor air distribution use Sonotex piping with silencer.

In the heat exchanger, the extracted air is cooled by the supplied air causing moisture condensation. Resulting condensed water
is drained towards the siphon. The condensate drain connection is found on the bottom of the heat recovery unit. A siphon,
which is connected to the sewerage system, must be mounted onto the coupling of the condensate drain connection (HT 32
mm (1.26 in) drain pipe).
