Nordson HSS User manual

Equipment required:
a Filled cartridges (Ratio-Pak®cartridges shown)
b HSS static mixer spray nozzle and air regulator kit
c HSS pneumatic spray gun
Note: To use Film-Pak®collapsible cartridges,
order a gun with built-in retainers or use
removable retainers with an existing gun.
If recommended by the product manufacturer,
pre-heat the cartridge for 1–2 hours at 32–38° C
(90–100°F). Do not exceed 49° C (120° F), as this
will affect the integrity of the cartridge.
Important: Consult with the product manufacturer
to determine whether shaking is required. If
shaking is required, gently agitate / shake new or
partially used cartridges for at least two minutes
prior to application.
Remove the retaining nut, compression disc, and
end cap(s) from the cartridge outlet.

If required, insert a ow restrictor.
Note: Some products require the use of a ow
restrictor to equalize material ow. Flow restrictors
are ordered separately. Contact your Nordson EFD
representative for the proper ow restrictor and for
installation assistance.
Seat an HSS static mixer spray nozzle on the
cartridge outlet, ensuring that the bell housing sits
ush on the tip of the outlet. If required, install a
retaining nut.
Note: Integral nut mixers do not require a retaining
nut; bell mixers do require a retaining nut.

Attach the air line of the HSS air regulator kit to the
HSS static mixer spray nozzle.
On the HSS regulator, place the ball valve lever (a)
in the closed position; then connect the plant air
supply (b) to the HSS regulator.
Point the gun up (a) and slowly dispense material
into the static mixer. Then dispense the rst 15 cm
(6") of unmixed material into a waste container (b).
Perform this process for each new or partially used
cartridge.
Important: Before increasing the uid pressure, verify that both material
components are traveling equally through the mixer. As needed, dispense
unmixed material into a waste container.
With the ball valve lever (a) in the closed position, set the HSS regulator (b) to
1.7bar(25psi); then slowly move the ball valve lever to the open position to
supply the spray nozzle with atomizing air. Adjust the HSS regulator and ball
valve lever until the desired operational settings are achieved.
Depending on the material, the material temperature, and the desired nish,
adjust the uid pressure regulator knob on the gun (c) as needed.
If applicable, hand-tighten the retaining nut
securely on the cartridge outlet threads (do not
over-tighten).
Insert the cartridge (or cartridge / retainer — not
shown) in the dispense gun, referring to the
applicable dispense gun instructions as needed.
