Problem solving

7.1

General causes

General

Malfunctioning can for example be caused by:

•

Mistakes made during installation

•

Pressures below the minimum pressure

•

Excessive amount of condensate (overloading)

•

Blocked or shut off outlet line

•

Excessive amount of dirt particles

•

Frozen piping

7.2

Faults and remedies

Danger:

Before starting any maintenance or repairs, close the air outlet valve and press the

test button on top of the electronic water drain to depressurize the air system.

Note:

Apply all relevant instructions in section Safety precautions.

Problem solving

Error

Reason

Solution

The drain does not discharge
condensate: the condensate
drain does not indicate an
alarm.

There is no condensate in the
condensate drain:

•

The external shut-off valve
between the discharge
point and the condensate
drain is closed.

•

The externally installed
filter is clogged.

•

The condensate drain has
not been installed correctly.
There may be a siphon
effect and/or air bubble
upstream of the
condensate drain.

•

The supply voltage is not
powering the condensate
drain.

•

Check the supply shut-off
valve of the condensate
drain.

•

Check the filter that might
be installed externally in
the condensate supply line.

•

Check the installation.

•

Ensure that the tube
leading to the compensate
drain is free.

•

Ensure that there is
electrical power.

•

If the aforementioned
points have been verified,
the condensate drain is
operating correctly.

•

Try a manual discharge
with the TEST button.
