FUNCTION

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.

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.)
