Shut-down Procedure
1. Remove the used nozzle by pushing down on the
nozzle ejector.
2. Apply petroleum jelly to the face of the INSTAFLO™ Gun.
3. Reinsert the used nozzle. This provides an airtight
seal during storage.
4. Turn off the in-line on-off valves. The valve handles
should be perpendicular to the chemical lines.
5. Turn off the on-off valves located near the chemical filters.
The valve handles should be perpendicular to the
chemical lines.
6. Turn off the chemical tank valves of the “A” and “B” tanks. The
handles should be perpendicular to the valves.
7. Turn off the yellow-coded nitrogen intake valves of the “A” and
“B” tanks. The handles should be perpendicular to the valves.
8. Turn off the nitrogen cylinder by turning the valve on the top
of the nitrogen cylinder in a clockwise direction.
9. Back out both nitrogen regulator valve stems until they are
freewheeling.
10. Coil the chemical lines to prevent possible tripping
and damage.
Section 7
Storage
1. Store in a dry area.
2. Store between 60°–80°F (16°–27°C).
3. Short term storage between 45°–60°F (7°–16°C) is permitted.
4. DO NOT store at temperatures above 120°F (49°C).
5. DO NOT not store near steam or hot water pipes.
6. DO NOT store near chimneys or heat vents.
7. If a partially used system remains inactive for a period of time,
the system should be pressurized and purged every two weeks.
This will prevent crystallization of the chemical in the hoses.
8. Unopened chemical tanks have a shelf life of approximately
one year.
Section 8
DO NOT breathe vapor or spray. Proper Personal Protective Equipment
and ventilation are required. See product SDS and Section 2 of this
manual for further information. Follow all precautions for product.
Re-Start-Up
1. Open the nitrogen valve fully to pressurize the system.
2. Open the two sets of valves on the chemical tanks for the A and
B sides and then the valves on the gun.
3. Remove the cured nozzle that you left attached to the gun.
4. Spray into a waste container. Ensure that you have good flow
from both the A and B side hoses.
5. Clean the face of the gun. Attach a new nozzle.
6. Spray a test sample to ensure good quality foam.
7. Resume spraying.
Re-start Procedure
8.1 System Pressurization
1. Verify that the valve stems on the regulator are backed
out and are freewheeling.
2. Open the nitrogen bottle valve by turning the knob on top of
the cylinder counter-clockwise. If a hissing sound occurs,
further tighten the nitrogen regulator valve stem with an
adjustable wrench. Use only in well ventilated areas. Wear
suitable respiratory protection.
