■How to operate
Turning handle set to "＋" side can increase circulation volume.
Turning handle set to "−" side can decrease circulation volume.
Safety precautions
Fire and explosion
1. Spark and open flames are strictly prohibited.
Paints can be highly flammable and can cause fire.
Avoid any ignition sources such as smoking, open flames, electrical goods, etc.
2. In case of PR-B5, never use the following HALGOGENATED HYDROCARBON SOLVENTS.
In case of PR-B5N, pay attention that its exterior does not come into contact with the
following halogenated hydrocarbon solvents.
which can cause cracks or dissolution on back pressure valve body (aluminum) by chemical reaction.
・unsuitable solvents：methyl chloride, dichloromethane, 1.2-dichloroethane,carbon tetrachloride,
trichloroethylene, 1.1.1-trichloroethane
（Be sure that all fluids and solvents are compatible with back pressure valve parts.
We are ready to supply a material list used in the product）
3. Securely ground back pressure valve by connecting to grounded metal bracket or grounded fluid pipelines.
Ground back pressure valve :Less than １MΩ. Check the earth stability periodically.
If not, insufficient grounding can cause fire and explosion due to static electric sparking.
Wrong operation of equipment
1. Before operation, confirm that each section is properly fitted and adjusted.
Install the pressure relief valve in connected piping route to let the paints pressure relief in the emergency.
2. Never spray toward people or animal.
If done, it can cause inflammation of eyes and skin or bodily injury.
3. Never exceed maximum operating pressure and maximum operating Temperature.
4. Securely connect it to fluid hose and pump or fluid pipelines to avoid leakage and looseness.
Ifnot,hazardoushosemovementandpaintejectioncancauseseverebodilyinjury.
Ifyouare injured,seea doctorimmediately withoutregardtothedegreeofinjury.
5. Be sure to use at lower than max. pressure 0.6MPa.
Use athigherthan max.primarypressurecancause damage whichisverydangerous.
Protection of human body
1．Use in a well-ventilated place to avoid serious injury caused by paints or solvents .
If not, poor ventilation can cause organic solvent poisoning and catch fire.
2. Be sure to reduce fluid pressure down to 0MPa before cleaning, disassembling or servicing.
If not, remaining pressure can cause bodily injury through ejection of cleaning liquid due to wrong operation.
3．During cleaning, disassembling or servicing, be sure to wear protective cover such
as glasses, masks or gloves.
If not, cleaning liquid, etc., can cause inflammation of eyes and skin.
If you feel something wrong with eyes or skin, immediately see a doctor.
Other precautions
1．Never alter this equipment.
If done, it can cause insufficient performance and failure.
2．Never use it for foods or chemicals.
If done, it can cause accident by corrosion in paint passages and foreign matter can cause health problems.
3．If something goes wrong, immediately stop operation and find the cause. Do not use again until you have solved the problem.
4．Never use commercial or other parts instead of ANEST IWATA original spare parts.
