READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
LOCATION
1. Pump can be located at the well or can be offset some distance
away from the well. For best performance it should be located as
close to the well as possible.
2. Location can be in the basement, a pit below ground or in a pump
house above ground.
3. Ventilation and drainage must be provided to prevent damage
from moisture to the motor and pressure switch.
4. The pump and all piping must be protected from freezing.
5. Pump and pipe line must be drained when not in use if there is
any danger of freezing.
WELL CONDITIONS
1. New wells should be pumped clean of all sand and foreign matter
before installing the pump or damage may result to the operating
parts.
2. The foot valve should be installed a minimum of five (5) feet
from the bottom of the well to prevent sand, mud or other foreign
matter from entering the system.
3. The well must be capable of furnishing a sufficient quantity of
water to satisfy the demands of the pump and personal needs.
The water level must not draw down below the maximum rated
depth of the pump or loss of capacity and prime will result.
4. For sanitary reasons, install a well seal or pitless adapter as
required and in accordance with local and state codes.
PIPING
1. Old or badly scaled pipe should not be used because dislodged
flakes of scale can cause stoppage of the ejector nozzle and
malfunction the entire system.
2. Use only pipe in good condition free from rust and scale.
Threads should be sharp, cleanly cut with a minimum of two (2)
threads remaining when connection is completely drawn up.
3. On galvanized steel pipe installations, the ends should be
reamed to insure maximum capacity.
4. All joints and connections should be doped (male threads only)
and drawn up tightly.
CAUTION
The entire system must be air and water
tight for efficient operation.
TYPE OF PIPE
1. Plastic or galvanized steel pipe may be used in the installation of
jet pumps.
2. Plastic pipe must have a minimum pressure rating of 160 PSI.
WELL TO PUMP PIPING
1. All offset piping should slope upwards from well to pump.
2. Avoid dips or pockets in offset piping or air will accumulate at high
points which will make priming difficult.
3. Install unions at pump and at well to aid in servicing.
4. Allow enough room around pump and piping installation for using
pipe wrenches and for service and installation.
5. Do not use piping of sizes smaller than those listed in Chart 1 or
pump will not operate properly.

EJECTOR AND PRESSURE SWITCH ATTACHMENT
1. Attach ejector to face of pump with two (2) bolts and gasket
provided. Venturi tube on the ejector inserts in the top tapping of
the face of the pump (Figure 1).
2. Screw pressure switch into tapping on side of pump as shown
(Figure 2).
3. Remove pressure switch cover to expose wiring terminals. Insert
motor lead wire through side hole of the pressure switch box and
attach to the two (2) flag terminals marked “load”. Leave switch
cover off for later connection of the power supply line.

NOTE:
For the pump to operate, the venturi tube of the ejector must
be positioned into the top tapping of the face of the pump.
WELL TO PUMP INSTALLATION
1. On single pipe installation (see Figure 3) attach foot valve to the
end of the suction line and set in the well making certain the valve
is below the water level. The foot valve should be at least five (5)
feet from the bottom of the well to prevent sand from being drawn
into the system.
2. When connecting a drive point (Figure 3) a check valve must be
used in the suction line in place of a foot valve. For easy priming
connect the check valve as close to the well as possible.
3. All piping from the well to the pump should slope slightly upward.
Unions in the suction line near the pump and well will aid in
servicing. Be sure to leave enough room so that wrenches can be
used without difficulty.
