The mixing chamber of the ColorWise nozzle will change from clear to blue
when cold chemical is sprayed through it. Stop spraying and ensure proper
chemical temperature to avoid off-ratio adhesive.
If proper chemical temperature is sprayed through a blue, cold nozzle, the
mixing chamber of the nozzle will change back to clear, indicating that it is
OK to spray. Notice that the top of the nozzle may remain blue.

recommendations.

NOZZLE CARE
•
Once the trigger is released, it must be reactivated within 30 seconds or a new nozzle must be installed. Failure to do this could
result in chemical leakage, spills, splashes or clogs which can ruin the dispensing unit and/or hoses.
•
Always make sure the face is covered with petroleum jelly (provided in nozzle pack) before attaching a new nozzle. This makes
removal of nozzles easier and protects the face of the gun hose assembly.
•
If foam has not cured, Polsolv
®
or acetone can be sprayed into the nozzle, making the nozzles reusable. Adhesive will cure inside
the nozzle in the same amount of time that adhesive becomes tack-free after being dispensed.
•
Cleaning the nozzles more than twice is not recommended.
•
Optimum chemical temperature is between 70–85°F (21–29°C). While your nozzle may stay clear between the 56–69°F (14–20°C),
the chemical is not conditioned properly. Therefore, when your nozzle does turn blue, your chemical has reached an extreme
cold temperature and needs to be properly conditioned before resuming spray. See TDS for product specific temperature
recommendations.

TEMPERATURE WARNING NOZZLES
Changes from clear to blue, indicating that the chemical has reached a cold temperature, below
60°F (16°C), and the adhesive should not be dispensed. Stop spraying and warm the chemical
to the recommended temperature. See TDS for product specific temperature recommendations.
• Nozzle will change from blue to clear when chemical temperature is back
in the acceptable range.
• Helps keep foam on ratio and maximizes yield.
• Available for use with Handi-Gun

Dispensing Units.
Divide the final weight of the A bag by the final weight of the B bag to calculate ratio. Desired ratio range are listed below (exclusions listed to the right). If ratio
achieved is not in the proper range, follow bulleted instructions
below
to adjust pressures accordingly.
ONCE THE PRESSURES HAVE BEEN ADJUSTED ACCORDINGLY, ATTACH A NEW RATIO NOZZLE TO THE HANDI-GUN
®
AND PROCEED WITH A SECOND
RATIO TEST TO BE SURE OF PROPER RATIO WHEN SPRAYING.
For optimum results, chemical is not recommended to be sprayed or applied outside of the correct chemical ratio listed above or specified chemical
temperature range available on the product specific TDS. Ratio test results will be required for technical service calls to ICP.
Record all ratio test results on the Daily Spray Log (A18013).
Equation used for most products (exclusions to the right):
1. Before attaching nozzle, use petro-
leum jelly on face of gun.
2. Insert bottom tab of nozzle into bot-
tom slot of dispensing unit.
3. Attach top latch by pushing towards
back of unit, until an audible “snap”
is heard.
4. Unit is ready to use.
5. After attaching nozzle, spray into
“test shot” receptacle. To ensure
equal parts A- and B-chemicals,
double check adhesive is curing.
6. To remove used nozzle, push top
latch up and forward to unsnap.
