Step 1: Pressurizing The System; Step 2: Verifying Cylinder Pressure; Step 3: Ratio Test; Step 4: Attaching The Nozzle - ICP HANDI-FOAM Instrucciones De Operación

STEP 1: PRESSURIZING THE SYSTEM

NOTE: The optimum pressures are located on the Refill Cylinder CG Sticker on all of the cylinders. If ques-
tions remain, contact ICP's Customer Care at: [email protected]; or by calling 330.753.4585 or
1.800.321.5585 for proper pressures before spraying (For Comfort RX
[email protected]). Pressures may vary from A to B cylinders and from system to system. Proper cylinder
pressures are critical to success. Pressures should be monitored closely at the initial setup as well as at the
start of each day.
1. Turn the regulator knobs on the nitrogen regulator (#1) counter-clockwise until they are free-spinning.
2. Connect the A-Side Red
3. Connect the Nitrogen Hose with Coupling (#3) to the B-Side cylinder.
4. Slowly open the nitrogen bottle until it is fully open.
5. Turn either the A or B-regulator knob clockwise until the required pressure for the specific cylinder is
displayed on the regulator gauge.
6. Open the Nitrogen On/Off Valve (#4) on the cylinder and fill with nitrogen until it reaches the required
pressure (can no longer hear pressure going into cylinder).
7. Repeat previous 2 steps for the B-cylinder.
8. Maintain a minimum of 500 PSIG in the nitrogen bottle at all times.

STEP 2: VERIFYING CYLINDER PRESSURE

NOTE: The nitrogen pressure regulator (#1) that is attached to the nitrogen bottle DOES NOT read the pressure
inside the refill chemical cylinder, only the regulated pressure coming from the nitrogen bottle.
1. Connect the pressure test gauge on the Nitrogen On/Off Valve (#4) on the A-Side cylinder. (Make sure the
pressure test gauge AND the nitrogen on/off valves are closed).
2. Slowly open the ball valve for the Nitrogen On/Off Valve (#4).
3. The pressure in the cylinder will register on the test gauge.
4. Close the nitrogen on/off valve and remove the test gauge from the cylinder and repeat the process on the B-Side cylinder.
5. The test gauge should be used at the beginning of each day and after any spraying breaks to determine and
verify the starting pressure in each refill cylinder.
NOTE: See Pressurizing The System for instructions on how to add nitrogen to each cylinder. NEVER use compressed
or supplied air.

STEP 3: RATIO TEST

Wear protective glasses with side shields or goggles, nitrile gloves, and clothing that
protects against dermal exposure. Recommended for use in a well ventilated area
with certified respiratory protection or a powered air purifying respirator (PAPR).
See Handi-brand Product Stewardship Guidelines for more information (A14009).
®
Prior to the A/B ratio test, open the cylinder valve stems and ball valves and purge the air
from the A and B side hoses, without a nozzle on the gun, until chemical is delivered.
After applying petroleum jelly to the face of the gun, attach the ratio nozzle* to the
gun hose assembly.
*If a ratio nozzle is not available, position the paper bags so the point where the bags meet is flush with the center of the face of the
gun. Ensure that both A and B streams are spraying into separate bags.
Weigh the empty A-side bag first and record weight on bag. Repeat step for
empty B-side bag.
Position paper bags so that each side of the nozzle is in a separate bag.
Pull full trigger and spray chemical through the ratio nozzle into the separate bags
for approximately 5–10 seconds.
Weigh the A-side bag first, then subtract the empty A-side bag weight. Record final
calculated A-side weight. Repeat step for B-side chemical bag.
Immediately after weighing bags, pour bag containing chemical A into the B bag to
create a low-grade foam. Dispose of cured foam and nozzle in accordance with local
regulations.
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.
Equation used for most Handi-brand

• Higher than a ratio of 1.20:
A
=
1.10 +/- 0.1 Add pressure in increments of 10 psig to the B side.
B
• Lower than a ratio of 1.00:
Add pressure in increments of 10 psig to the A side.
1.00
*Not applicable for Window Lineal foam.
ONCE THE PRESSURES HAVE BEEN ADJUSTED ACCORDINGLY, ATTACH A NEW RATIO NOZZLE TO THE HANDI-GUN
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.
