Section 6

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. Follow all requirements for a new kit including wearing

all PPE, and ensuring proper ventilation and isolation

of spray area are in tact.

2. Open the valves on the chemical tanks for the A and B sides.

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.

Troubleshooting.

Maintenance and after-use instructions.

The Froth-Pak

™

Kit is virtually maintenance-free and many

problems can be corrected through simple troubleshooting

techniques. When troubleshooting, conﬁrm that the system is

pressurized correctly, and that all chemical valves are in the

open position.

7.1 Temperature

Liquid material temperature can affect foam quality. If the

Liquid mat-erial temperature is below 65

°F (18 degrees C),

poor quality foam may result. The ideal temperature range

is 75-90 degrees F (24-32 degrees C) , minimum 65 degrees F

(18 degrees C). See Section 11, Tank Heating.

7.2 Troubleshooting

Problem: Spray pattern becomes noticeably different (i.e. cone

spray changes to stream)

Solution: This may be caused by dispensing foam with a used

nozzle. Always inspect a nozzle prior to dispensing to make sure

you have an unused nozzle mounted in the Insta-Flo

™

Dispenser.

Problem: Foam or spray pattern does not react properly

Solution: Replacing the nozzle will usually correct the problem.

If the problem persists and foam is friable or brittle, the foam

is “ISO” rich, and a partial blockage of the “POLYOL” side exists.

If foam remains soft or mushy, the foam is “POLYOL” rich and

a partial blockage of the “ISO” side exists. If foam starts to be-

come liquid, then there is a total blockage of one side. Remove

the nozzle and carefully activate the dispenser into a waste con-

tainer. Two chemical streams of approximately equal volume

should ﬂow. If streams are unequal, a blockage has occurred.

Shut off the tank valve on the side that is ﬂowing properly and

activate the trigger full force for 15 seconds. Once the blockage

is freed, turn off all tank valves. Clean any chemical from the

face of the Insta-Flo

™

Dispenser with a clean rag and reapply

petroleum jelly. Insert an unused nozzle, open all valves and

dispense a test shot into a waste container. After curing, check

the foam quality. If blockage occurs again, stop foaming, turn

off chemical tank valves, eject the used nozzle, and release

chemical line pressure by activating the dispenser into a waste

container. Slowly loosen the hose connections at the tank

valves. Clean chemical from the threads and replace with a new

Insta-Flo

™

Dispenser/Hose Assembly. (Go to the Answer Center

at www.frothpak.com and follow the troubleshooting tips for

the Froth-Pak

™

Foam System.)

the foam quality.

If the replacement of the Insta-Flo

Dispenser/Hose Assembly

does not solve the problem, please contact our technical staff

nozzles are available with alternative spray patterns and

various dispensing rates.
