This pump must always be vented prior to using.
The vent cap/dip stick is the primary means to vent the
reservoir. It is attached to the pump when you receive
the unit. The vent cap/dip stick must be installed in the
pump before activation. The pump was shipped with a
temporary hex plug in the reservoir. It is located in the
front right corner of the reservoir. Remove the hex plug
and replace it with the vent cap/dip stick. Do not over
tighten the vent cap/dip stick.
The below picture shows the dipstick, which is pointing
toward the temporary hex plug that it should replace.
