against flooding and excess moisture. The well also should be protected for sanitary reasons. Mount the pump as close to
the well as possible.
TANK - PRE-CHARGED STORAGE
The 6 gallons pre-charged storage tank has a flexible bladder that acts as a barrier between the compressed air and water.
This barrier prevents the air from being absorbed into the water and allows the water to be acted on by compressed air at
initially higher than atmospheric pressures. The pressure was pre-set as 28 psi in the factory. If the air pressure less than 28
psi, you may need to pump air into the tank before you start the pump.
For wells 25 feet or less in depth, shallow well installations should be adapted. The shallow well
installations have only one single pipe between the pump and well water.
SHALLOW WELL INSTALLATION
MATERIALS REQUIRED (NOT INCLUDED)
One can PVC cement & primer (read instructions carefully)
One well seal with vent plug
One can thread compound (read instructions carefully)
Foot valve
Teflon tape
Discharge tee/Priming tee and plug
Rigid pipe
Relief valve
Check valve
Adaptor
Flexible plastic pipe/clamps
Tank(for AUTO series tank is included
）
Tank tee
WARNING:
All joints and connections must be AIRTIGHT. A single leak will prevent the proper operation of the pump. Wrap
thread tape clockwise on all threaded connections. For all non-threaded connections, you must use PVC Purple Primer and
PVC Cement to ensure airtight seals. Measure all pipe lengths before attaching.
NOTE:
A foot valve is a check valve that is used to keep the water from running back into the well from the pump and
maintain hydraulic pressure when the pump is not running. If the foot valve does not hold the water the pump will lose it’s
prime and will not pump water. If the foot valve open pressure is too high (the spring is too stiff), or the flow area is too small,
the pump suction head and flow rate will significantly drop.
NOTE
: The suction pipe size should not be less than 1-1/4 in. The suction size of this pump is 1-1/4 in. FNPT.
CAUTION:
To avoid skin burns, unplug the pump and allow time for it to cool after periods of extended use.
