CLEANING THE CYLINDER
When scaling and deposit inside the cylinder prevent sufficient current passage between
electrodes or obstructs water discharge, clean the cylinder.
NEVER EXTRACT THE CYLINDER WITH MACHINE HOT AND WITH
WATER INSIDE. BEFORE CARRYING OUT THE OPERATION, COMPLETELY
DISCHARGE THE CYLINDER USING THE MANUAL DISCHARGE KEY!
IT IS COMPULSORY TO FOLLOW THE PRESCRIPTIONS INDICATED IN
CHAPTER 7.2
1. Extract the cylinder from the humidifier by following steps 1-6 described in chapter 7.4
2. Using the hole in the upper part of the cylinder, clean and eliminate scaling present on the
electrodes and on the accessible parts by means of mechanical action using a plastic spatula and
running water or a water and acetic acid at 20% (Fig. 38). Carry out the same operation on the
louvres of the lower filter (Fig. 39). During cleaning, do not damage or scratch the coupling
parts guaranteeing water seal, like the O-rings seat or the inlets of the flanges. During cleaning,
do not wet the connector or the UM-CA-01 cable-carrier ring (Fig. 40).

3. Clean and check integrity of the two O-rings, replacing them if required, and check their correct
positioning inside the two seats arranged on the cylinder. Insert cylinder repeating the removal
operations in reverse order, checking the exact positioning. Use the lubricant provided with the
humidifier to lubricate the mechanical couplings to facilitate insertion operations.
4. Completely wash the cylinder two or three, using the "manual discharge" key.
5. After one hour of functioning from cylinder insertion, check there are no water leaks inside the
humidifier.
