63600A MANIFOLD OVERVIEW

The 63600A Series of automatic air atomizing manifolds is a system of customizable manifolds of nozzles for spraying a multitude of liquid materials, including paints and lacquers, greases, release agents, corrosion preventives, adhesives, and ceramic glazes. A complete nozzle assembly consists of a fluid nozzle and air cap installed into a body which is permanently affixed to a manifold weldment.
Additionally, the 63600A manifolds are specifically designed to also spray a wide variety of food ingredients, such as oils, syrups, slurries, chocolate, and peanut butter. The 63600A manifolds operate on the principle of pneumatic atomization (also commonly referred to as 2-fluid atomization), where liquid is discharged from the nozzle orifice and then atomized with compressed air, nitrogen, steam, or other pressurized gas. The spray pattern is then further shaped by pattern or fan air, which impinge on the atomized spray.
The 63600A manifolds of automatic nozzles are air controlled, operating in conjunction with a 3/2-way control valve. The 63600A manifolds are provided with an integrated hot water jacket for fluid temperature control. The manifolds contain only food grade materials of construction and are type 316 stainless for corrosion resistance. The manifolds are provided equipped with either Type J or Type VMA air atomizing set-ups. Manifolds may be field converted from one nozzle system to the other.
Manifolds can alternatively be constructed in a radial (“deadhead”) or recirculating arrangement. The liquid volume is ultimately controlled by the nozzle orifice size and supply pressure, however the nozzles are supplied with an adjusting knob for individual control. The adjusting knob throttles the orifice from fully open to completely closed.

3.1 AIR CONTROL
The 63600A manifolds are available with or without integrated air control. When equipped, the nozzle will shut-off the atomizing and fan air when closed. Actuation of the control valve directs air into the cylinder chamber of the nozzle so as to open, in sequence, the atomizing and fan air, followed immediately by the liquid. Upon closing the control valve, this process is then reversed: the cylinder air will discharge, and the piston spring will shut-off the liquid, followed im- mediately by the atomizing and fan air.
For nozzles without integrated air control, an external control valve must be provided by the user for shutting off the atomizing and fan air supply. It is suggested by Spraying Systems Co. that a short anticipation and following timing be applied to the air supplies relative to the nozzle control valve in order to ensure complete atomization of the liquid. Simultaneous actuation may result in dripping or spitting at the beginning or end of the spray cycle.
The manifolds have independent fan and atomizing air supply feeds, and these air pressures must be controlled via external regulators.
For J-Style nozzles, the fan air supply is unused.

SECTION 4 INSTALLATION

Securely attach the manifold to equipment framing or other structure that will bear the weight of the manifold. Be sure to account for the added weight of the fluid to be sprayed and the jacket water (if used).

4.1 AIR AND FLUID HOSES

Use only filtered, non-lubricated air for atomizing (“AIR”) and fan (“FAN”) air supplies. These connection ports are 1/2” NPT(f). Cylinder (“CYL”) air may be lubricated or non-lubricated. It is recommended the cylinder air supply be regulated separately from the atomizing air supply. The cylinder port is 1/8” NPT(f). For best performance, the control valve for the cylinder air should be fitted as closely as possible to the manifold inlet. Longer distances will result in slower nozzle response. When using a Type J set-up, install a 1/2″ NPT plug into the FAN connection port.
For fan and atomizing air supply, minimum 5/8” OD (16mm) tubing is recommended. 1/4” OD (6mm) tubing is recom- mended for the cylinder air supply. Measure air supply pressure as close to the manifold block as possible for most accurate reading of nozzle pressure.
When so constructed, the liquid supply is designed to recirculate through the manifold. Either side may be used as supply or return. For deadhead operation, install a 1” sanitary cap onto the liquid return port.
CAUTION : The manifold must be grounded to dissipate any electrostatic charges which may be created by air or fluid flows. This can be achieved through the mounting of the manifold or through the use of conductive piping/hoses. Electrical bond from the manifold to ground should have a resistance of less than 10 6 Ohms.

SECTION 5 OPERATION

5.1 SET-UP

Check that the cylinder end cap is properly tightened.
Loosen the adjusting screw such that approximately a ¼” gap is present between the end cap and the knob.
Loosen the retaining ring slightly and align the air cap to the desired orientation. Tighten the retaining ring by hand. Do not use a wrench or other tools to tighten the retaining ring. Damage to the air cap and retaining ring may occur.

5.2 START-UP

Always turn off air and liquid supply and relieve pressure when not in use. Flush clean if nozzle will be idle for a pro- longed period of time.
Optimal spray height is 6” to 8” (15 – 20 cm) from surface. Nozzle should be positioned perpendicular to target.

Regulate the fan and atomizing air and liquid pressure to zero.
Actuate nozzle and increase the liquid pressure until fluid flows from the nozzle. If target flowrate is desired, adjust liquid regulator and/or adjusting knob until flow reaches target application rate. Once set, actuate nozzle closed.
Set atomizing air pressure to approximately 20 psi (1.4 bar) and activate nozzle. Inspect spray pattern and adjust atomizing air pressure to desired drop size. If the spray is too fine, decrease air pressure. If the spray is too coarse, increase air pressure.
Slowly turn up fan air pressure until desired pattern is achieved.

MAINTENANCE

WARNING : Shut-off air and liquid supply and relieve all pressure before performing any maintenance.
PREVENTIVE MAINTENANCE
Remove air cap and clean. If any holes are clogged, clear out with a soft- bristle brush or toothpick. Never use metal wire or picks to clean any nozzle orifice.
Check that the fluid nozzle is clean and free of any damage or debris. Build- up of material or damage to the fluid nib can distort the spray pattern.
REPLACEMENT OF PARTS
Remove the retaining ring and air cap from the gun.
Unscrew the adjusting knob and remove the liquid spring. The fluid nozzle can now safely be removed. NOTE: Always remove spring pressure from fluid nozzle before removing. Unscrewing the nozzle under load can damage the fluid nozzle and/or needle, leading to dripping or leaking when the gun is shut-off. Remove the needle, and unscrew the end cap to remove the main spring.

CAUTION : The needle may be sharp and can puncture skin. Always handle shut-off needles with care.

Inspect the needle bushing and replace if necessary by unclipping it from the side.
Thread the adjusting screw into the back of the piston and pull to remove from gun body. Inspect the lip seals and replace if necessary. Note the orientation of the seals: the “U” of the larger lip seal should face towards the nozzle, while the smaller seal should face towards the back of the gun.
The air valve plungers can now be removed from the sides of the piston. It is advisable to replace the air plunger orings whenever the gun is disassembled. Remove the seal cartridge with a 9/16 (14mm) deep-well socket. The seal cartridge cannot be serviced, so if worn, replace entirely. Tighten the new cartridge between 10 to 12 ft-lbs (13.5 to 16 Nm). Apply a thin layer of o-ring lubricant or petroleum jelly to the air plunger o-rings and the piston seals. Align air valve plungers with their respective holes and push the plunger assembly into place. Wipe away any excess lubricant from the gun body.
Apply a thin coating of anti-seize lubricant to the threads of the air module and replace the air spring and end cap. The end cap need only be hand- tightened. Ensure the needle bushing is properly installed on needle. Apply a thin layer of lubricant to the needle and install needle through the end cap, piston, and seal cartridge. Replace the liquid spring and adjusting screw.
