7.5. CONDENSATION DRAINPIPE
Inspect the drainpipe regularly and make sure it is not blocked, if this is the case, remove the obstruction.
Check that the drain pipe was done according to the indication included in the point CONNECTIONS of this manual.
The siphon should always be full of water. Check its level periodically, refilling it if necessary. An empty siphon can cause
the condensate tray to overflow and water leak through the equipment enclosure.
