The Reactor is tested with oil at the factory. If nec-
essary, flush out the oil with a compatible solvent
before spraying. See page 37.
Equipment and hoses contain some residual
moisture. Do not load with isocyanate and leave
unused for a long period. Pumping and spraying
helps remove moisture from system.
