Compression Tank has a rubber bladder 1.
inside. This bladder must be pumped
up to 26-29 PSI of air at all times. Use a
bicycle pump (not included) to inflate the
bladder. On the end of the Compression
Tank opposite the side with the Pressure
Meter, is an air valve located under a
cover. Remove the cover over the air
valve and periodically monitor this air
valve with an air pressure gauge to
insure that the rubber bladder maintains
the required air pressure.
Make sure the intake pipe is fully
2.
submerged before continuing.
Before starting the pump for the first
3.
time, prime it by pouring clean water
into the Priming inlet.
This is a self-starting pump that uses a
4.
pressure switch. Once the power cord
is connected and the unit is switched on,
the pump can start at any time. do not
handle or perform maintenance on the
pump if the power cord is plugged in.
To begin pumping, plug in the power
5.
cord and turn the switch on. When the
line is pressurized, the pump will go to
standby mode until the pressure falls
below its starting pressure.
