A the Manufacturer is constantly committed in the continuous improvement of its entire production, the aesthetic and dimensional features, the technical data, equipment and accessories may be subject to variation.
!
This instruction book is an integral part of the appliance and as a consequence must be kept carefully and must ALWAYS
accompany the appliance even if transferred to other owners or users or transferred to another plant. If damaged or lost,
request another copy from the Manufacturer.
!
Repair and maintenance interventions must be carried out by authorised staff or staff qualified according to that envisioned
by this book. Do not modify or tamper with the appliance as dangerous situations can be created and the appliance manufacturer will not be liable for any damage caused.
!
After having removed the packaging ensure the integrity and completeness of the content. If this is not the case, contact the
Company that sold the appliance.
!
The appliances must be installed by enabled companies in compliance with the Law 5 March n° 46 which, at the end of the
job issues a declaration of conformity regarding installation to the owner, i.e. in compliance with the Standards in force and
the indications supplied in this book.
!
Any contractual or extracontractual liability of the Manufacturer is excluded for injury/damage to persons, animals or objects
owing to installation, regulation and maintenance errors or improper use.
We remind you that the use of products that employ electrical energy and water requires that a number of essential safety
rules be followed, including:
This appliance must not be used be children and unaided disabled persons.
It is prohibited to touch the appliance when you are barefoot and with parts of the body that are wet or damp.
It is prohibited to perform any maintenance or cleaning operation before having disconnected the appliance from the
mains electricity network, by positioning the plant master switch at "off"
It is prohibited to modify the safety or adjustment devices without the manufacturer’s authorisation and precise instructions
It is prohibited to pull, detach or twist the electrical cables coming from the unit even if it is disconnected from the electrical mains
It is prohibited to climb onto the unit, sit on it and/or rest any type of object on it.
It is prohibited to spray or jet water directly onto the unit.
It is prohibited to open the doors for accessing the internal parts of the appliance without first having switched off the master switch of the "system".
It is prohibited to disperse, abandon or leave the packing materials within the reach of children, as they are a potential
source of danger

Important Note
The heat recovery unit is a machine designed and built exclusively to change air in the civil environments,
incompatible with toxic and inflammable gases. Therefore it cannot be used in those environments where the
air is mixed and/or altered by other gaseous composites and/or solid particles.
The use of the same for different purposes from those envisioned, not conform to that described in this
manual, will make any direct and/or indirect liability of the Manufacturer automatically become null and void.

Heat Recovery Units Installation, Use and Maintenance Manual
INTRODUCTION
The heat recovery units for horizontal installation are characterised by small dimensions and easy assembly.
The heat recovery units allow to join maximum environmental comfort with sure energy saving.
Forced ventilation must be created in current air conditioning and treatment plants, which leads to the expulsion of treated air,
determining large energy consumption and increase in costs.
The HRS heat recovery unit range intend to solve these problems using a static heat recovery unit that saves more than 50%
of the energy that would otherwise be lost.
SECTION 1 - GENERAL FEATURES
1.1 Manual presentation
This manual states the information and that deemed necessary for transport, installation, use and maintenance of the HRS
range heat recovery units.
The user will find that which is normally useful to know for correct safe installation of the heat recovery units described.
Failure to comply with that described in this manual and inadequate installation of the heat recovery unit causes the annulment
of the warranty that the Manufacturer gives its heat recovery units. Moreover, the Manufacturer is not liable for any direct and/or
indirect damage due to incorrect installation or damage caused by units installed by unskilled and unauthorised staff. On purchase, check that the machine is integral and complete.
Any claims must be made in writing within 8 days from receipt of the goods.
1.2 Construction features
• Panels realised in Aluzink sheet steel, removable for inspection and maintenance.
• Acoustic and heat insulation of the panels using polyethylene/polyester with average thickness of 20 mm.
• Fresh air intake and double intake centrifugal type expulsion fans (for the HRS 30 model with simple intake) with directly coupled electric motor.
• Fan body mounted onto anti-vibration mounts so as not to transmit any vibrations.
• Air filters with G3 efficiency, easily extractable laterally, to allow periodical cleaning.
for the HRS range
• Terminal boards on machine to ease the electric connections and fan control.
• Condensate drip tray in ABS with low condensate drain connection.

It is possible to intake or expel the air frontally and
laterally by simply changing the position of the
panels, as illustrated at the side.
This can simplify the realisation of the air ducts
greatly, bringing an effective saving to installation
times.
