Before you get started make sure you have the following to hand:
? Gloves
? Safety Goggles
? Protective overalls
? Spanner for connecting hoses (one of the correct size is normally supplied in the pack)

Surface Preparation
Area of application should be clean, dry and free of grease, oil, dust or dirt. Ensure the area has adequate ventilation. If flow-through ventilation isn’t possible, wear a respiratory mask, if the smell becomes overwhelming, exit the area until the fumes dissipate. No fumes or vapours are released from the foam once it has cured.

Getting set up
Before setting up make sure the tank contents and surface to be insulated are at the correct temperature. Tank contents should be between 60-80oF (15.6-26.7oC) during dispensing. To ensure maximum performance ambient and substrate temperature should be 60-80oF (15.6-26.7oC), preferable 70-80oF (21-26oC). Agitate the tanks by shaking the cylinders to thoroughly mix contents and ensure an even distribution of temperature.

Check the Gun for Proper Function
Good quality foam depends upon one-to-one ratio dispensing. The easiest way to determine that you have good ratio is to observe the stream of chemicals coming out of the gun before they pass through the mixing nozzle. Be sure that both chemicals are dispensing from the gun PRIOR to your application, ALWAYS do a test shot into a waste container. To do this, remove the nozzle from the gun and point the gun into a waste container.

Step by step

1. Put on gloves, safety goggles and suitable clothing or overalls. Set up the system in an upright position (valve on tanks facing up) and open the top of the carton. Take the gun applicator/hose assembly out of the carton.

2. Through the openings in the back of the carton, connect the hoses to the tanks, hand tighten, then tighten thoroughly with a spanner.

3. Slowly open up the valve on each tank. Make sure both the tanks are FULLY OPENED. Check the hose/tank connections for leaks.

4. Fold flaps to re-close box.

5. The gun applicator is set to the OFF position when manufactured. To unlock, push switch to the ON position.

6. Direct the gun applicator into a waste container. Squeeze the trigger completely. Make sure that two strong streams spray out of the gun applicator.

7. Select a disposable mixing nozzle and align the slots on the nozzle with the notch on the gun applicator barrel. Push the nozzle onto the notch and turn clockwise to lock in place.

8. Point spray nozzle into a waste container. Slowly squeeze the trigger and check for that the chemicals are properly mixing. The foam should be off-white in colour, not white or dark brown and should cure to a tack free surface in 30-45secs. If foam is not the correct colour or is not curing properly, make sure the valves on both tanks are turned fully on and agitate the tanks. If the foam is still not curing, contact your supplier

9. To stop/pause spraying, release the trigger of the gun. If spraying is stopped for 30secs or more, remove the mixing nozzle. To re-commence spraying, fix a new nozzle to the gun applicator.
