4.2 CONDENSATE DRAINAGE
Moisture can condense on the surfaces of the air coolers and heat recovery exchanger.
from the air. The condensed moisture (condensate) flows into the drip tray located below these functions.
The installer must connect the drip trays to the drainage system, including the use of traps. Condensate
drainage is led outside the air handling unit casing. The outlets are located in the condensate drip trays
of the coolers (the diameter of the drain pipe is 32 mm).
!
! For the correct operation of the air handling unit, it is required to install traps for the baths on
the suction side of the fan (on negative pressure).
! It is recommended to use siphons for baths located on the discharge side of the fan (on positive
pressure).
! Ball valves cannot be used on the discharge side of the fan.
! It is not possible to combine different condensate drains into one trap.
!
Fill the siphon with water before starting the air handling unit.
!
If the environment is cold, insulate the drainage pipes.
!
If the condensate is in danger of freezing, a suitable system for heating it must be used.
