Please note
The use of leak detection spray can result in
faulty operation.
Leak detection spray must not come into contact
with electrical contacts.
Note
Only use suitable and approved leak detection agents
(EN 14291) and devices for the tightness test. Leak
detection agents with unsuitable constituents (e.g.
nitrides, sulphides) can cause material damage.
Remove residues of the leak detection agent after test-
ing.

secure.
Danger
If the trap is not full, flue gas can escape.
Escaping flue gas can cause life threatening
carbon monoxide poisoning.
Always fill the trap with water.
5.
Reconnect the condensate drain hose for the neu-
tralising system to the trap. Route the condensate
drain hose without kinks and with a constant fall.
