Operating Guide

4. Insert an unused nozzle with the key slot down. Push
in firmly until the nozzle ejector is seated over the back
rim of the nozzle.
5. Dispense foam to verify proper chemical mixing. If
improper mixing or poor foam quality, refer to the
Troubleshooting section, Section 7 of this manual.
3.2 Nozzle Replacement
1. 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 below as a guide.
This chart is for the cone and fan type nozzles. Other
specialty nozzles may have different elapsed paused
times.
2. To replace the used nozzle, push down the nozzle
ejector. The used nozzle should eject.
3.2.1 Using the Kit
Replace nozzle when nozzle has not been used for more
than 30 seconds. Nozzle is removed by firmly depressing
the yellow ejector located at the top of the Insta-Flo
™
Dispenser. Before applying foam, make a small test shot
into waste container to verify foam quality.
Insert an unused nozzle with the key slot down. Push
in firmly until the nozzle ejector is seated over the back
rim of the nozzle. The kit is ready to operate.
Section 4
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.
4.1 Application
READ ALL DIRECTIONS BEFORE USING
1. Chose the nozzle with the pattern and flow rate
appropriate for the job. Attached 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 Insta Flo
™
Dispenser about 6”-24” (15 cm -
60 cm) away from the area you intend to spray. Apply
foam by squeezing trigger. Note yellow safety on the
trigger mustbe depressed first, unlocking trigger. Move
the Insta-Flo
™
Dispenser with a steady back and forth
motion when dispensing foam. 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. It is important to note that two-component foam
products will release heat while the liquid froth cures
into the final solid. They should be applied in layers of
2 inches or less to allow the foam’s heat to dissipate
between sprayings.
6. 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. Foam will expand and will be tack free within
60 seconds (3 –4 minutes for slow rise formulas), and is
fully cured in five minutes. It is recommended that foam
be applied in layers of 2” or less in any single application
layer. Note: If the foam is to be injected into a hidden
cavity, a test shot is recommended prior to each injection.
