MANUAL USE MODES
The section of this manual dedicated to the installation contains information for installers. For this reason we have used technical terms without
providing explanations which would be necessary for end users only.
THE INSTALLATION MUST BE CARRIED OUT BY AUTHORIZED AND SKILLED PERSONNEL ONLY. ARAG IS NOT RESPONSIBLE
FOR ANY OPERATION SPECIFIED IN THIS MANUAL CARRIED OUT BY UNAUTHORIZED OR UNSKILLED PERSONNEL.
• RESPONSIBILITY
The installer must carry out "workmanlike" installations and ensure to the end user the perfect operation of the whole system both with ARAG
components only and other brands' components.
ARAG always recommends using its components to install control systems.
The installer will be held responsible for any malfunction if he decides to use other brands' components even without actually changing the system
parts or harness.
The compatibility check with components and accessories of other manufacturers shall be carried out by the installer.
If the ARAG components installed together with other brands' components get damaged because of what stated above, no direct or indirect warranty
will be provided.

SAFETY GUIDELINES
CAUTION:
All installation and maintenance operations must be carried out by qualified personnel with circuit not under pressure and
without power supply (connector disconnected).
Use suitable tools and any individual protection equipment deemed necessary.
Use ONLY clean water for spraying tests, calibrations and simulations: using chemicals during simulated spraying runs can
seriously injure persons in the vicinity.
Do not operate the valve with no load for long periods of time, as this might damage the components inside the valve.
ARAG declines any responsibility for direct or indirect damage deriving from the type of fluids used in the system.
The use of such substances is made under the full responsibility of the operator, who therefore must follow the safety measures
indicated by the fluid manufacturer on the package and wear suitable personal safety equipment (gloves, coverall, boots,
helmet, etc.) in compliance with the law provisions.
ARAG may not in any way be held responsible for accidents or damage to persons, animals or objects caused by improper,
unprotected, or non-recommended use of the products utilized.
