3.4 Maintenance
Do not use, under any circumstances, flammable liquids or detergents to clean the unit.
Always wait a few minutes after turning off to allow the system to go into rest condition (temperature and pres-
sure).
During maintenance operations, do not dispose of any residues in the environment, but comply with the regula-
tions in force.
NEVER remove the cylinder unless specifically indicated.
Do not perform any repair or maintenance operations when the unit is running or connected to the mains.
Perform exclusively the maintenance and repair operations indicated in this manual. Operations performed by
unexperience persons will affect the overall safety level of the unit and expose the operator to serious risks.
3.5 Electrical power supply
The power supply of the unit must be connected according to the instructions of CTR S.R.L. , the company however, is not respon-
sible for the connection. The safety of the unit is effective only when it is properly connected to an electric energy source that has
all the protections as required by the current applicable legislation (differential safety switch and earthing).
• The connection to the mains must be made using the plug provided with the unit, and a reduction used if necessary,
checking beforehand that the line voltage corresponds to that indicated on the label on the rear of the unit.
• In the event of damage, contact only our Technical Service Dept..
If the power plug needs to be replaced, contact our Technical Service Dept. and do not replace it unless written
permission has been given by our competent department. Failure to follow this instruction, will relieve CTR S.R.L.
of any responsibility for personal injuries or property damages caused by the power supply.
If using extensions, check that the cross-section of the cable is appropriate for its length and that it is positioned
in such a way that it cannot be damaged in any way (avoid walkable and wet areas).
Check that the point of connection to the electric energy source has all the protections as required
by the applicable legislation (earthing and differential switch).
