Operating Guide

Problem: Hose becomes clogged
Soultion: If the dispenser hasn’t been used for a week or lon-
ger, activate the system for a few seconds by turning on the
tank valves and squeezing the trigger fully without a nozzle
attached to dispense twin streams into a waste container.
This clears and re-pressurizes the hoses and should be done
weekly when the system is idle. Re-apply petroleum jelly and
reinsert used nozzle for storage.
Identifying and fixing an off ratio
foam mix
Please perform these tasks before
returning a kit.
Your ratio may be uneven if:
• Foam will not cure completely, is soft
to the touch or sags off the substrate. This means the
B tank is dispensing quicker than the A tank, causing an off
ratio mix.
• Foam cures and looks brittle and flaky with “honeycomb”
type areas. This means the A tank is dispensing quicker
than the B tank, causing an off ratio mix.
• Either of the two above can occur if the tank product is
low and needs to be replaced.
Solution:
1. Turn both A and B tanks off.
2. Remove Spray Tip.
3. Check temperature of the tanks. Should be 75–85° F
(24–29° C) for optimal performance.
4. Shake both A and B tanks for 45 seconds.
5. Turn B tank on and purge into empty trash can.
6. Continue to engage the gun trigger for 30–60 seconds until
a consistent stream is seen. Turn B tank off.
7. Turn A tank on and purge into empty trash can.
Continue to engage the gun trigger for 30–60 seconds
until a consistent stream is seen. Turn A tank off.
8. Connect a new spray nozzle.
9. Fully turn on both the A and B tanks.
10. Test spray into empty trash to ensure foam is curing
correctly.
11. Complete the project.
Section 8
Disposal and Clean-up
Disposal must be performed in a well-ventilated area
(preferably outdoors). Never puncture or incinerate cylinders.
1. Wear the same PPE (personal protective equipment)
as used while applying the two-component foam
(i.e., NIOSH approved negative respirator with organic
vapor cartridges and P-100 particulate filters, goggles/
face shield, gloves and protective clothing).
2. Liquids (A & B) remaining in Froth-Pak
™
kits must be
disposed of as solid waste foam material, not liquid
chemicals. Steps 3 through10 are intended guidelines
necessary to convert any residual liquids into solids
prior to proper disposal.
3. Carefully dispense liquids from the cylinders with the
gun and nozzle attached. Dispense liquid materials out
of the cylinder(s) as foam until one or both compo-
nents/cylinder(s) are empty.
4. Carefully remove the nozzle from the gun and
continue to depressurize the cylinder(s) by dispensing
the liquid materials into a waste container lined with a
plastic bag that has adequate absorbent (e.g., sawdust,
kitty litter, dry absorbent) in the bottom.
5. Carefully close both cylinder valves completely, then
operate the gun trigger to empty and depressurize
the hoses.
6. Lift each cylinder. The cylinder should feel empty,
with no sloshing of liquid.
7. Carefully remove the hoses from the cylinders.
Use caution: in case there is some residual liquid
material and/or pressure still in the hoses. Place hose
in plastic bag with absorbent material as in Step 4.
8. Carefully place cylinder(s) over a waste container
lined with a plastic bag. Slowly open the valves on
the cylinder(s) to catch any residual material. With
cylinder pointed away from face, allow pressure
to completely vent. Always handle and vent
cylinders in a well-ventilated area while wearing
all proper respiratory protection.
