For extended storing, or between use in cold climates, drain all
pumped liquids from pump and flush with antifreeze solution to
prevent freezing and damage to the pump. DO nOT RUn
PUMP WITH FROZEn lIQUID.
Note: Each system’s maintenance cycle will be unique. If
system performance decreases, check immediately. If no wear at
500 hours, check again at 1000 hours and each 500 hours until
wear is observed. Valves typically require changing every seal
change. Duty cycle, temperature, quality of pumped liquid and
inlet feed conditions all effect the life of a pump’s wear parts and
service cycle.
Note: Remember to service the regulator/uploader at each
seal servicing and check all system accessories and connections
before resuming operation.
