Insta-Flo ™ Gun Operation; Spraying - DuPont FROTH-PAK Manual

Section 5
DO NOT breathe vapor or spray. Proper PPE and ventilation
are required . See product SDS and Section 2 of this manual
for further information . Follow all precautions for product .

5.1 Spraying

1 . Once the calibration is complete, chose the nozzle with
the pattern and flow rate appropriate for the job . Attach
the nozzle .
2 . Practice on scrap material or plastic sheet to get the feel
of spraying and to ensure you are making good foam .
3 . Hold the gun a consistent distance from the work and
perpendicular to the work . Move in a steady side to side
stroke . Avoid swinging the gun, it will result in variable
thicknesses of foam . The speed of your movement and
the distance from the work will determine the thickness
of the foam .
4 . Always fully engage the trigger of the gun . Partial
engagement can result in off ratio foam .
5 . Let the foam cure (a minute or two) Look for an even
tan color foam . Watch to see that it rises 3 or 4 times
the original thickness . Make sure the foam has cured
and is firm .
6 . If the foam looks unusual, verify the calibration settings
and that the tanks are 75–90 degrees . (Minimum 65
degrees) . Then remove the nozzle and purge material
into a waste container for 15-30 seconds . Clean the face
of the gun, insert a new nozzle and perform a test
spray again .
7 . If problems persist call your DuPont rep or the DuPont
Contact Center (833-338-7668) .
8 . While spraying, always watch for signs of unusual looking
foam . Troubleshoot as outlined above .
9 . Watch for any bubbles in the translucent hoses near the
gun and listen for any sputtering . This may be a sign of
empty tank .
5.2 Insta-Flo Gun Operation
™
The Insta-Flo Gun provides greater flow control and mini-
™ mizes waste when used properly . The following operating
instructions ensure
maximum efficiency and performance of
the Insta-Flo ™ Gun .

1 . DO NOT breathe vapor or spray . Proper PPE and
ventilation are required . See product SDS and Section 2
of this manual
for further information . Follow all precautions
for product .
2 . To insert an unused nozzle, verify that the key slot on the
nozzle is in the down position . Push in firmly until the nozzle
ejector is seated over the back rim of the nozzle .
3 . To meter the Insta-Flo Gun, engage the trigger one-third
™
to one-half . This should be done sparingly due to the ratio of
the foam being affected .
4 . The life of a nozzle depends on elapsed paused spraying time
and chemical temperature . Replace a previously used nozzle
if the elapsed paused spraying time is exceeded using the
chart on the right as a guide .
5 . When spraying is completed, remove the used nozzle by
pushing down on the nozzle ejector .
6 . Apply petroleum jelly to the face of the Insta-Flo
7 . Reinsert the used nozzle . This provides an airtight seal
during storage .

Section 6
Shut Down
1 . When shutting down the refill system for the day, leave the
cured nozzle attached to the gun to keep moisture from
penetrating the hoses .
2 . Shut off the A and B side valves on gun and the two sets of
valves on the chemical tanks for the A and B sides .
3 . Leave all hoses attached .
4 . Shut off the main nitrogen valve at the nitrogen tank . Do
not adjust the regulator levels that were established during
calibration . These settings can be used until the chemical
tanks are empty or the nitrogen tank is replaced as long as
there are no big temperature swings .
5 . Remove the used nozzle by pushing down on the nozzle
ejector .
6 . Apply petroleum jelly to the face of the Insta-Flo
7 . Reinsert the used nozzle . This provides an airtight seal
during storage .
