MAINTENANCE
Cleaning the trap
1. Loosen the trap ring.
2. Check that the condensate exhaust pipe is not blocked.
3. Clean the trap with soap and water.
4. Make sure to leave enough water in the trap before reassembly, or pour 20 cl of water
in the condenser before reassembly.
5. Insert the trap in the condenser outlet. Replace the O-ring if necessary.
6. Hold the trap in position by re-tightening the ring. Pull the trap downwards to check it
is secured.
