Fig.1
Condensate through the feed line is accumulated in the housing. When the upper flow sensor detects the
condensate level and sends a signal with the electronic control device, the valve is activated to open the
diaphragm, and the condensate is discharged.
Upon discharge, the lower flow sensor detects the level, stops the valve and closes the diaphragm.
▶ Press 'TEST' briefly
(for less than 1 second)
to check operational status
(manual discharge)
Normal Mode
You may experience error in the following cases:
▶ Incorrect installation
▶ Overload owing to excessive generation of condensate
▶ Poor discharge owing to blocked (by foreign materials, freezing etc) discharge line
▶ Poor discharge owing to the internal pressure being less than the min discharge pressure (0 bar)

In the error event, the system is switched to the emergency mode turning the alarm signal and activating the auto
recovery function to allow forced open of the valve for 5 seconds every 3 minutes.
Upon auto recovery or correction of the error by repair, the alarm signal will flicker and the system will be returned to
the normal mode.

INSTALLATION
The condensate line must be installed
separately.
With linear pipe line, arrange the pipe
line so that condensate is separated
from air.
The condensate feed line shall not sag
to ensure smooth feed.
With a long condensate feed line, install
an air vent line.
With a parallel piping to a tank, install a
vent line to the pressure gauge.
(Condensate may not flow due to
pressure when the housing is filled with
air.)
