6.1 - General information
6.2 - Hydraulic circuit maintenance
After the appliance has been running for a few days, it is advisable
to check that the water circuit is watertight and that condensates
are draining correctly.
N.B: In case of maintenance work or decommissioning
an appliance, please respect all environmental
protection instructions concerning recovery,
recycling and disposal of consumables and
components.
Checking the water circuit consists of removing sludge, checking
the  lters and stopping up any leaks that may have appeared.
Clean or replace clogged or dirty  lters.
Check from time to time that the condensates are draining
properly:
- Remove the back panel
- Check the drainage hole for blockages
- Clean the condensates collection trough as deposits from air
intake may accumulate here.
- Clean the  exible drainage hose
Case a : drainage from underneath
Cas b : drainage from the back
Check that the pressure relief valve is properly sealed. It should
not leak if the water pressure is under 2.5 bars.
