air at the factory. Check the tank Owner's Manual to
find if air charge needs adjustment. Your pump re-
quires 30 pounds for proper operation.
The jet pump can also be mounted on standard hori-
zontal tanks. A kit consisting of all necessary piping, el-
bows, and other fittings, is furnished with the tank for
mounting pump using this method. See Figure 3, Page
4. Instructions are included with tank.

Included With Standard Horizontal Tank
There is a 1-1/4" x 1/4" reducer bushing and a 1/4" x
1-1/2" nipple supplied in the fittings package. Use the
one that fits into the air volume control tapping in the
end of the tank as shown in Figure 3, Page 4. Use pipe
compound on male threads. Screw the air volume con-
trol on to the 1/4" fitting and the right angle compres-
sion fitting into the bottom tapping of the air volume
control.
Remove the 1/4" pipe plug, Key No. 13, Page 10, on
the jet portion of the pump body near the check valve.
Insert a 1/4" compression fitting into this tapping. Cut
tubing to length and assemble the two fittings in the
air volume control and pump body. Use nuts, sleeves,
and inserts furnished.

Priming the Pump
Never run pump dry. Running pump
without water may cause pump to
overheat, damaging seal and possibly causing
burns to persons handling pump. Fill pump with
water before starting.
Never run pump against closed dis-
charge. To do so can boil water inside
pump, causing hazardous pressure in unit, risk
of explosion and possibly scalding persons han-
dling pump.
DO NOT START MOTOR UNTIL PUMP HAS BEEN
FILLED WITH WATER.
1. Remove the priming plug. fill pump with water.
Replace priming plug. If a priming tee and plug
have been provided at the well head for a long hor-
izontal run, be sure this tee is filled and the plug re-
placed, using pipe compound on plug threads. See
Figure 1, Page 3.
2. Start the pump. Water will be pumped in a few min-
utes; the time depending upon the depth to water,
and the distance of horizontal run. If pump does
not prime, check for a possible leak on the suction
side of the pump. Reprime. Check to be sure suc-
tion lift – distance from water level to pump – does
not exceed 20 feet.
