To Attach Nozzle - Handi-Gun
®
Dispensing Unit
1. Before attaching nozzle, use
petroleum jelly on face of gun.
2. Insert bottom tab of nozzle into
bottom slot of dispensing unit.
3. Attach top latch by pushing towards
back of unit, until an audible “snap” is heard.
6. To remove used nozzle, push top
latch up and forward to unsnap.
4. Unit is ready to use.
When spraying for the first time, or when starting a new kit, it is recommended to trigger the gun only 1/2 to 3/4 open, until the desired output and spray pattern
is achieved. This controllable metering ability is a major advantage of the gun, allowing the user complete control of the flow rate and spray pattern that best
fits the application. Apply several test shots on plastic or cardboard before beginning the job.
EXTREMELY IMPORTANT
-
WHEN SPRAYING IS STOPPED FOR MORE THAN 30SECONDS, THE NOZZLE SHOULD BE REMOVED AND REPLACED WITH
A NEW NOZZLE.
The chemical in the nozzle will begin to cure and will clog the nozzle when spraying has stopped for more than a few minutes. If the trigger
is pulled while a clogged nozzle is on the gun, the chemical from the cylinders (which is under pressure) will be blocked by the clogged nozzle and will cause a
“back- ‐up” of chemical into the hoses, which is called a crossover. The gun will no longer dispense chemicals in the right proportions and the Polyset adhesive
will not function properly. This situation can be easily avoided by simply changing nozzle when spraying is stopped for more than 1 minute.
Adhesive Test Spray
5. After attaching nozzle, spray
into “test shot” receptacle.

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
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.
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.

NOZZLE CARE
• Apply a small amount of petroleum jelly to help keep the gun face clean from cured adhesive or contamination that
could block one of the chemical ports.
• Nozzles are cleanable and solvent resistant. In a timely manner, the nozzles can be flushed of uncured foam with Polysolv.
• Adhesive will cure inside the nozzle in the same amount of time that adhesive becomes tack-free after being dispensed.
To prevent clogs and ensure trouble free operation, change nozzle after 30 seconds of non-use.
