not compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump
head, valves, seal rings, balls and LIQUIFRAM™ (diaphragm). Reassemble head assembly
tightening screws in a crisscross pattern. Refill the pump head with the solution to be pumped
before priming the pump. (This will aid in priming.)
