1. TRANSPORTATION AND STORAGE OF EQUIPEMENT
Heat Recovery Unit (hereinafter – the Unit) is prepared for transportation and storage. Packaging
materials ensure protection against exposure to environment, dust and humidity. The Unit must be
properly secured during transportation to protect it against possible housing deformation or other
mechanical damage.
Transportation conditions:
-20oC - +40oC.
Long-term storage conditions:
+5oC - +40oC, relative air humidity <= 50%.
CONSIGNMENT ACCEPTANCE:
Carefully check the received consignment – make sure that the number of packages matches
with the consignment documentation. Upon noticing any non-conformity or damage of the
package (tears, dents or compressed box, detached or reattached packaging tape), inform the
courier immediately and indicate the disrepancies or damages in the consignment document.
Verify if the right product was delivered. Upon noticing any non-conformity, inform the Sender
immediately.
Verify if all the supplementary parts listed were delivered. In case of any doubt, contact the
Sender immediately.
Do not attempt to repair the Unit, damaged during the transportation by yourself!
IMPORTANT! Sender does not assume any obligations towards damage or loss of the Unit or its part,
if there is no a corresponding record in the consignment document!

3. SAFETY REQUIREMENTS
Carefully read and follow safety requirements provided below before installing and while operating
the Unit:
Do not discard the Installation and operation manual, keep it for future reference.
The Unit should be installed and operated in compliance with this Installation and operation
manual, following the requirements of effective legislation and standards.
When connecting the Unit to mains supply, grounding must be installed in compliance with
requirements of effective legislation and standards.
To prevent accidents and potential damage to the Unit it should be installed, connected,
maintained and repaired only by qualified technician. Never attempt to do this by yourself!
Turn off the Unit by using Control panel and wait for fans to stop completely before replacing
air filters.
Turn off the Unit by using Control panel, wait for fans to stop completely and disconnect the
Unit from mains supply before performing any maintenance.
Disconnect the Unit from mains supply before disconnecting or reconnecting the control
panel.
Before connecting the Unit make sure that no items will get sucked into the its air intake
openings!
The Unit is not intended to be used by persons (including children) with reduced physical,
sensory or mental capabilities, unless they have been instructed to use the Unit and under
constant supervision of person held responsible for their safety.
Children may only use the Unit under adult supervision.
Only original supplementary parts and consumables, certified by manufacturer should be
used.
The Unit package (cardboard, plastic, foam polystyrene) can pose hazard to children. Dispose
or recycle the package elements!
Disused Unit should be disposed in accordance with requirements of legislation on handling
of waste electrical and electronic equipment.
IT IS PROHIBITED to operate the Unit with damaged mains supply cable! Switch off the power
circuit-breaker to disconnect mains supply and contact a qualified technician or manufacturer
service centre immediately upon noticing such damage.
IT IS PROHIBITED to attempt the repair of the damaged Unit or its part, to open its cover!
Contact a qualified technician or manufacturer service centre.
IT IS PROHIBITED to operate the Unit while construction works are still in progress to remove
dust or excess moisture. Fine dust of building materials, used in construction, can irreversibly
change characteristics of the heat exchanger or cause damage to sensitive electronic
components. Failure of the Unit caused by such operation will void the warranty.
