0.25 scfm 1.0 scfm 0.5 scfm

Pattern air temperature 0 _C (0 _F) aboveadhesive temperature

14 _C (25_ F) aboveadhesive temperature

0 _C (0 _F) aboveadhesive temperature

Pattern air pressure(see Note B)

3 psi (0.2 bar) 15 psi (1 bar) 5-8 psi (0.3-0.6 bar)

NOTE A: Avoid using too much air pressure. Maintaining larger adhesive filaments will improve process stability,increase bond strength, and reduce air consumption.

B: The pattern air flow path is critical. Ensure that the pattern air supply lines are properly sized and that theyare not kinked in a way that restricts air flow.



Operational CapabilitySummit nozzles are available in a variety of orifice sizes, including astandard size (0.018 in.) and a high flow size (0.024 in.). Standard nozzlesprovide adequate performance in the majority of applications and are thedefault nozzle selection. Larger orifice nozzles are less susceptible toclogging and provide higher flow at lower pressure.

Most production environments require a range of flow rates at a fixedmaterial viscosity. Application requirements will determine the selection ofnozzles. To aid in nozzle selection, some nozzle capabilities are showngraphically in Figures 4 and 5.

Nozzle ServiceRemoving or Installing a Nozzle

You will need the following items:S Appropriate tools, including a torque wrenchS Drain pans and disposable ragsS O-ring lubricant (for lubricating nozzle O-rings)

WARNING! System pressurized! Relieve system hydraulic pressure beforebreaking any hydraulic connection or seal. Failure to relieve the systemhydraulic pressure can result in the uncontrolled release of hot melt or coldadhesive, causing personal injury.

WARNING! Molten material! Wear eye or face protection, clothing thatprotects exposed skin, and heat-protective gloves when servicing equipmentthat contains molten hot melt. Even when solidified, hot melt can still causeburns. Failure to wear appropriate personal protective equipment can resultin personal injury.

Remove a Nozzle1. Heat the system to application temperature.2. Relieve system pressure. Refer to the applicator manual as needed.3. Trigger the applicator solenoid valves to relieve any remaining pressure.4. Shut off the module-actuating air.5. Decrease the pattern air pressure. Leave just enough air pressure to

prevent adhesive from entering the pattern air outlet on the module.See Figure 6.6. Back the nozzle-retaining clamp screw all the way out until it stops (1).7. Push up (2) on the nozzle-retaining clamp screw to eject the nozzle.

Install a NozzleSee Figure 6.1. Clean (3) the mating surface where the nozzle will be seated.2. Inspect the nozzle seal, replace if necessary, and ensure that the seal is

lubricated and properly positioned in the seal bore.3. Carefully angle and insert the nozzle in the module seat (4, 5).

Cleaning NozzlesYou will need the following items:S Appropriate tools, including a torque wrenchS Nozzle cleaning kits (refer to Parts)S Cleaning supplies (refer to Table 1)S Drain pans and disposable ragsS O-ring lubricant (for lubricating nozzle O-rings)

1. Remove the nozzles. Refer to Remove a Nozzle earlier in this section.2. Clean the nozzles using one of the Nordson-recommended methods

shown in Table 1. Use only cleaning agents recommended by theadhesive supplier.

WARNING! System pressurized! Relieve system hydraulic pressure beforebreaking any hydraulic connection or seal. Failure to relieve the systemhydraulic pressure can result in the uncontrolled release of hot melt or coldadhesive, causing personal injury.

WARNING! Molten material! Wear eye or face protection, clothing thatprotects exposed skin, and heat-protective gloves when servicing equipmentthat contains molten hot melt. Even when solidified, hot melt can still causeburns. Failure to wear appropriate personal protective equipment can resultin personal injury.

WARNING! Risk of explosion or fire. Follow the safety guidance and heatingrecommendations on the Material Safety Data Sheets (MSDSs) for youradhesives and nozzle-cleaning solutions.

WARNING! Risk of explosion or fire. Use a controlled heating device, suchas a thermostatically controlled hot plate, to heat cleaning fluid, includingNordson Type-R fluid.

CAUTION! Risk of equipment damage. Do not use a wire brush (or a brushwith bristles harder than the nozzle) to clean nozzles.



Table 1 Nozzle Cleaning MethodsCleaning Method Procedure

Citrus-based solutionand ultrasonic tank

NOTE: This is the mostthorough method.

a. Place the nozzles in citrus-based solvent/degreasing solution and soakthem overnight or for approximately 4 hours. This dissolves and loosens theadhesive and char buildup.

b. Remove the nozzles from the citrus-based solvent/degreasing solution andplace them in an alkaline solution heated to the appropriate temperature(refer to the MSDS) in an ultrasonic tank. Soak the nozzles forapproximately 10 minutes. This will remove adhesive and char from theorifices.

c. Scrub the nozzles with a soft, non-metallic brush to remove debris.d. Gently blow air through the nozzle orifices from the mounting side of the

nozzle.Nordson Type-R fluid a. Place the nozzles in a controlled heating device containing Nordson Type-R

fluid and heat it above the melting point of the adhesive (refer to theMSDS).

b. Scrub the nozzles with a soft, non-metallic brush to remove debris.

Electric heat gun a. Heat the nozzles with a flameless electric heat gun.


Ultrasonic tank a. Place the nozzles in an alkaline solution heated to the appropriatetemperature (refer to the MSDS) in an ultrasonic tank. Soak the nozzles forapproximately 10 minutes.


c. Gently blow air through the nozzle orifices from the mounting side of thenozzle.

Cleaning Nozzles (contd)Table 1 Nozzle Cleaning Methods (contd)

Cleaning Method Procedure

Oven (all-steel nozzlesonly)

WARNING: Risk of explosion, fire, or toxic vapor release.Depending on the type of adhesive and/or organic solvent usedwith the nozzles, heating them in an oven can cause a hazardousevent. Before using an oven to clean nozzles, consult with theoven manufacturer about the viability of this method and thesafety risks. Follow the manufacturer's recommendations.WARNING: Use the oven heating controls to keep the oven at thedesired temperature. Do not use an oven that does not haveheating controls.

CAUTION: Risk of equipment damage. Remove O-rings beforecleaning nozzles in an oven. Failure to do so can cause a chemicalreaction that will permanently damage the nozzles.

a. Ensuring that O-rings have been removed from the nozzles, place themin an electric oven heated to approximately 385 _C (725 _F). Allow thenozzles to bake for approximately 3-4 hours.

WARNING: The heating temperature and time may need to beadjusted based on the oven type, the adhesive type, and theamount of char buildup on the nozzles. Nordson Corporationrecommends testing this procedure on discarded nozzles prior tousing it on good nozzles.

WARNING: Risk of fire. Use a heat-proof cloth to clean nozzles. Evencotton can burn in high-temperature conditions.

WARNING: Risk of equipment damage. Handle nozzles carefully toavoid denting the orifices, which can degrade the adhesive pattern.

b. Turn off the oven and allow the nozzles to cool; then remove thenozzles.

c. Wipe the nozzles with a soft cloth and then gently blow air through thenozzle orifices from the mounting side of the nozzle.



3. If there is any remaining char buildup on the nozzles, gently scrape thechar from the nozzles.

CAUTION! Risk of equipment damage. Use of an open torch, drill, or broachcan damage a nozzle. Use only a pin-type probe to clean nozzle orifices anddo not twist the probe inside the nozzle.

4. If cleaning of the nozzle orifices is necessary, use a pin-type probe that isone size smaller than the orifice size: insert the probe in the directionopposite the adhesive flow, wipe the probe, and then remove the probewithout twisting it, as shown in Figure 7.NOTE: For available nozzle cleaning kits, which contain a holder andseveral probe sizes, refer to Parts.

Figure 7 Correct direction to insert a pin-type probe into a nozzle

5. Reinstall the nozzles. Refer to Install a Nozzle earlier in this section.6. Restore the system to normal operation.
