Control torques and types of bypass and mixing flap actuators:
The exchanger bypass flap can be controlled by an ON / OFF actuator (LMxxA, CMxx) or a continuous actuator (LMxxA - SR, CMxx-SR). It is
recommended to control the mixing flap only with a continuous type of actuator (xxxx-SR). The location of the actuator is on the back of the flap
- after opening the front door opposite to the view side.
For better accessibility, it is recommended to install the actuator before starting to
connect the unit to the piping network.
5.2.9 INLET AND EXHAUST FLAP (ODA-FRESH AIR, ETA-EXHAUST AIR)
The basic version of the unit is equipped with a fresh and exhaust air inlet flap (ODA and ETA). The arrangement of the flaps in the unit is shown
on the picture above. When using a variant of the unit with a water heater DCA or DCB, it is recommended to mount an actuator with an
emergency function on the fresh air inlet flap.

5.2.10 BASIC ACCESSORIES
5.2.10.1 CONDENSATE DRAIN TRAPS
Condensate traps must be ordered as a separate item as they are not included with the unit.
Vacuum type siphon scheme (SF-P 300):
bottom edge of the
condensate tray unit
check valve - ball
floor level
270
The vacuum siphon (SF-P300) contains a ball that serves as a non-return valve for the proper function of the water-free siphon and prevents
odours from entering the unit. The siphon must be fitted to the unit gas-tightly via the enclosed rubber sleeve. Maximum usable vacuum
1100 Pa.
