ELECTRICAL CONNECTION
ROUTINE MAINTENAINCE
• Always remember to clean the preheater after use to prevent
the fluid from solidifying inside it when it cools down.
• Disconnect the electrical connection and let the fluid circulate for
a few minutes until the preheater has cooled down before using
the solvent for washing, thus avoiding the sudden expansion of
the solvent inside the preheater due to the heat with consequent
increase of pressure.
Always disconnect the power supply before
carrying out any type of check or replacement
of the electrical components of the preheater.
