How much oil must be in the tank to operate the P43®?
In general, the recommended minimum level of oil is such that the tank roof is floating with the roof legs in the high position. The roof legs should then be raised to the low position during the operation of the P43®, so as not to impede the jet penetration. The P43® is equally effective with the tank completely filled with oil. The greater amount of overhead oil the better the solubility.
