NOTE 1: Guns with HVLP caps must not exceed 0.7 bar (10 psi) air cap pressure
with gun fully triggered. (Aproximately 26 psi gun inlet pressure.) (See
accessories for air cap test kits which are available to set the exact cap
pressure.)
Compliance with SCAQMD and other air regulatory agencies requires gun
inlet pressure not to exceed 1.5 bar (22 psi) with gun fully triggered when
the high efficiency cap is used. Gun inlet pressure may be adjusted as
required to any desired value in areas not requiring EPA compliance.
NOTE 2: When removing air cap from retaining ring, don't remove slip ring (2)
or retaining ring seal (5) from retaining ring. Damage to the parts may
occur. Slip ring and retaining ring seal are not available as replacements.
Simply wipe parts clean and reassemble with new or clean air cap.
