b) Connect the air hose to the supply connector.

are closed (the isocyanate hose to the isocyanate coupler and the polyol hose to the
polyol coupler).

WARNING!
When handling chemical products, always follow the supplier’s safety and storage
instructions.
To prevent splash contamination between one tank and the other, open only the cap of
the tank being filled with product.
Never swap parts between one tank and the other, and always use the same tank for the
same product.
WARNING!
To prevent cross-contamination of products, make sure the tanks are properly closed.
To avoid spillage during transportation of the unit, never fill the tanks completely: always
leave about 20% of the tank capacity free (each tank holds 30 litres).
We recommend using small vessels (10-15 litres maximum) for pouring product into the
tanks.
Fill the tanks with the amount of product required for each application.
