7. If the foam looks unusual, verify that the tanks are at least
75 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.
8. If problems persist call your Dow rep or Dow Technical service.
9. While spraying, always watch for signs of unusual looking
foam. Troubleshoot as outlined above and in section 7.
10. Watch for any bubbles in the translucent hoses near the
gun and listen for any sputtering. This may be a sign of an
empty tank.
WARNING: CURED FOAM IS COMBUSTIBLE AND WILL
BURN IF EXPOSED TO OPEN FLAME OR SPARKS FROM HIGH
ENERGY SOURCES. These products should not be sprayed
where the foam may come into contact with hot surfaces,
such as heaters, furnaces, fireplaces, or recessed lighting
fixtures. The foam should NOT be exposed to temperatures
over 240F (116C).
4.2 INSTAFLO™ Gun Operation
The INSTAFLO Gun provides greater flow control and minimizes
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. If the spray flow rate needs to be higher or lower, use a
different colored back cap nozzle (refer to the nozzle chart
on page A4). DO NOT partially open the INSTAFLO
™
Gun
trigger to meter the flow as this will change the ratio of the
foam and affect the foam quality.
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 previous page 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 Gun.
7. Reinsert the used nozzle. This provides an airtight seal
during storage.
8. Close both of the cylinder valves for storage.

Storage
1. Store in a dry area.
2. Store between 7585°F (2429°C).
3. Short term storage between 45°–60°F (7°–16°C) is permitted ,
but the chemical must be warmed up before spraying.
4. DO NOT store at temperatures above 120°F (49°C) or below
45°F(7°C).
5. DO NOT not store near steam or hot water pipes.
6. DO NOT store near chimneys or heat vents.
7. To store a partially used kit (use kit within 30 days of opening):
Shut both cylinder valves completely. Leave hoses pressurized
to keep moisture from air out of hoses. Clean end of gun and
reapply petroleum jelly to face of gun. Re-insert a used nozzle in
the gun to keep air and moisture out of the gun/hoses
8. If a partially used system remains inactive for a period of time,
the system should be purged every two weeks. This will prevent
crystallization of the chemical in the hoses.
9. Use by date on carton lid.
