Operating Instructions and Parts Manual
Pre-Installation
PACKAGE SYSTEMS
There are four jet pump/tank assem-
blies sold as packages (Chart 1).
WELLS
A new well should be pumped clear of
sand before installing the pump. Sand
will damage the pumping parts and
seal. The drawdown level of the well
should not exceed the maximum rated
depth for the pump. The capacity of
the pump will be reduced and a loss of
prime may occur.
Installation
LOCATION
Select a location as close to the water
supply as possible.
Be sure to comply with any state or
local codes regarding the placement of
the pump. The equipment must be pro-
tected from the elements. A basement,
frost proof pit or heated pump house
are good locations. Make sure the
pump has proper ventilation. The tem-
perature surrounding the pump is not
to exceed 100° F (40°C) or nuisance
tripping of the motor overload may
occur.
PIPING
Piping may be copper, steel, rigid PVC
plastic or flexible polyethylene plastic.
Flexible pipe is not
recommended on
suction pipe (inlet pipe).
The pipe must be clean and free of rust
or scale. Use a pipe joint compound on
the male threads of the metal pipe.
Teflon
®
tape should be used with plas-
tic threads. All connections must be air
tight to insure normal operation.
Slope all inlet piping upwards towards
the pump to prevent trapping air.
Unions or hose couplings can be
installed near pump to facilitate

removal for servicing or storage. A rub-
(Cont'd)
ber hose installed between the water
system and the house piping will
reduce the noise transmitted to the
house.
Plastic pipe can be used on all installa-
tions except 2" deep well jet. The 2"
deep well jet requires 1
steel pipe and special machined cou-

The galvanized steel pipe and the cou-
plings restrict the flow of return water
back to the jet unless the couplings are
machined.
PIPE SIZES
Long horizontal pipe runs and an
abundance of fittings and couplers
decrease water pressure due to friction
loss. See Chart 2 to determine the prop-
er pipe size.
SHALLOW WELL INSTALLATION
A shallow well jet assembly can be used
with the deep well pump when the
pump is located 25 feet vertically of the
water level. Shallow well installations
have only one pipe between the pump
and water supply (Figure 3).
DRILLED WELL (FIGURE 15)
1. Install a foot valve on the first sec-
tion of pipe (Figure 3, Illustration
A).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 5
feet below the lowest anticipated
water level.
18" from the bottom of the well or
sand or sediment could be drawn into
the system.
4. After proper depth is reached,
install a well seal or pitless adapter
to support pipe and prevent surface
water and other contaminants from
entering well.
