8.8 Nozzle Filters
Each nozzle assembly is equipped with a 50 mesh fi lter screen as
standard on units equipped with a 20 GPA Red ISO Color Tips™.
Properly maintained suction fi lter and self cleaning fi lter will eliminate
the plugging of screens and nozzles.
8.9 In-Line Filters (Optional)
If in-line fi lters are fi tted, they should be cleaned every 8 hours (daily).
Unscrew the bowl to remove sediment.
8.10 Nozzle Tubes And Fittings
Poor seals are usually caused by:
• Missing O-rings or gaskets
• Damaged or incorrectly seated O-rings
• Dry or deformed O-rings or gaskets
• Foreign materials
Therefore, in case of leaks;
DO NOT
overtighten any fi ttings.
Dis as sem ble, check the condition and position of the O-ring or gasket,
clean, lubricate and then reassemble. For
radial
seals (O-ring) only
hand tighten the fi ttings. Do not use pliers or wrenches.
