Operating instructions for SCHLICK double material nozzle Model 970 Vers. 4 according to drawing D4.484/4-1
Construction characteristics:
The nozzle is designed for static load. The design, construction and testing of the nozzle have been done according to
Guideline 97/23/EG and the AD 2000 regulations.
Installation of the connected hoses:
Clean the propellant and liquid hose before connecting the nozzle. Connect the propellant (pressurised air, gas)
to the connection marked “L” respectively “air”, the liquid to the connection marked “F” respectively “liquid”.
The size of the connection thread for the nozzle is G 1/8" IG for both hoses.
Ensure that both hoses are completely tightly connected.
Operating condition:
Propellant:
The propellant atomises the liquid at min. 0.3 bar (ü). The propellant consumption depends on the setting of the air cap
and the pressure of the propellant. At a higher propellant pressure and the same liquid throughput, the fineness of the
atomisation is increased. The air cap is furnished with a scale for precise adjustment of the propellant throughput and
resetting to the same throughput after cleaning.
Air cap completely screwed in = cap setting 0 = the nozzle is closed.
Then open the air cap by four graduation lines = cap setting 4 = normal cap setting
The appropriate air cap setting is determined by experimentation depending on the usage purpose. When the air cap is
turned anti-clockwise, the propellant throughput is reduced and the jet stream becomes more pointed. When the air cap
is turned clockwise, the propellant throughput is increased and the spreading cone becomes wider (at constant propellant
pressure). For compressed air flow at various air cap settings and pressures, se performance diagram (pages 18+19).
Liquid:
Add liquid through pressure or gravity.
The liquid throughput can be manually adjusted with the needle, independently of the current pressure, continuously from
0 to maximum. For maximum throughput (water) for various diameters and pressures, see performance diagram (pages
20+21).
If the liquid throughput is reduced at constant propellant pressure, the fineness of the atomisation is increased and vice versa.
Switching the nozzle on and off:
When switching on, first open the propellant valve and then the liquid valve.
When switching off, first close the liquid valve and some ten seconds later the propellant valve in order to avoid dripping
of the liquid.
Care for and cleaning of the nozzle:
The nozzle must be tested for defects and greased at suitable, product-dependent intervals. Depending on the spray
medium, the nozzle must be cleaned regularly. Only suitable cleaning solutions, cloths, plastic spatulas, ultrasound cleaner
or the like must be used for cleaning. No hard objects!
When cleaning the nozzle, parts subject to wear (such as packings and/or gaskets) must be visually checked for damage
and if necessary replaced.
