IMPORTANT!

 Owner of the Unit shall ensure the possibility to perform Unit maintenance. If there is 

not  enough  space for Unit maintenance, the manufacturer´s representative is  entitled to  refuse  to 
perform maintenance or repairs. 

 

7.4.

 

Ventilation system balancing 

 

It is necessary to balance the supply and exhaust air flows of the air handling unit during first launch 
of the ventilation system. Ventilation system will ensure proper heat recovery and the lowest possible 
electricity consumption during the cold season only if properly balanced. 

System has to be balanced according to ventilation system installation project. Balance the supply 
and exhaust air flows by adjusting values for Fan1 and Fan2 in the operating parameters setting menu 
of  control  panel  with  touchscreen  display  (refer  to  section  1.5  of  Operating  parameters  setting 
manual) or using P3 and P4 controls of control panel with the knob (refer to section 9.3.6 "Additional 
system settings"). 

There is a risk of heat exchanger freezing when operating an unbalanced ventilation system during 
the cold season, as a result of which air handling unit may start supplying cold air to the premises. 
Unexpected indoor air moisture condensation can occur on the supply air ducts. 

 

IMPORTANT!

 Balancing of the system can only be entrusted to qualified professional possessing all 

the necessary properly calibrated technical equipment. 

IMPORTANT!

 Request a ventilation system passport to be prepared. 

IMPORTANT!

  Freezing  of  heat  exchanger  which  occurred  during  operation  of  an  unbalanced 

ventilation  system  can  irreversibly  change  the  properties  of  the  heat  exchanger  and  damage  the 
internal air tightness of the Unit. Failure of the Unit due to freezing while operating the unbalanced 
ventilation system will void the warranty!
