Solvent can spray under high pressure.
➔ Observe appropriate safety procedures (for example, goggles, safety gloves and
protective clothing), when opening flow path.
Deformation of fittings and seals
Liquid drops under high pressure up to 1200 bar act like solid parts. Tightening
connections under high pressure can deform or destroy fittings and seals.
➔ Never tighten flow connections under pressure.
The lifetime of a fitting depends on how firmly it has been tightened; firm tightening
reduces the lifetime.
If fitting has been overtightened, replace it.
