copper or PVC pipe may be used. To
avoid strain on the pump when using
iron or copper pipe, provide indepen-
dent supports for both suction and dis-
charge piping near the pump. Minimize
use of elbows and fittings to reduce
friction loss. Refer to the friction loss
chart (page 5) for specific information.
Increase diameter of suction or dis-
charge piping if length is over 50 feet.

SUCTION PIPING

Install foot valve
or strainer screen
over intake of suction piping.
Never use pipe smaller than 1
eter for suction piping. Keep suction
pipe free of air leaks. For horizontal
runs, lay pipe from the water source so
the upward slope is at least 1/2" per
foot. This eliminates trapped air. The
threaded inlet of the pump is 1
Do not install suc-
tion piping near
swimming areas.

cross with 3/4" NPT pipe plug (sold sep-
arately). Insert tank tubing into side
opening of pipe cross. Insert PVC pipe
into remaining side opening for con-
nection to home water supply line.
CONNECTION TO WATER TANK
CONVENTIONAL TANK (SEE FIGURES 3
& 4)
A conventional water tank stores water
and pressurized air in the same com-
partment. When full, the tank contains
approximately 2/3 water and 1/3 com-
pressed air. This type of tank requires
an air volume control, which automati-
cally replaces air lost due to leak or
/ " diam- absorption into the water.

4. Bolt pump to the floor or the

5. Install air volume control on tank.
6. Connect the tube from the air vol-
ume control to the front 1/8" NPT
opening on the side of the pump.
Connections must be tight. Leaks
will cause the pump not to prime
and/or the tank to become water-
logged.

the system for service or storage.
9. Slope horizontal lines up toward
pump a minimum of 1/4" per foot.
This will prevent trapping air in the
lines.
PRE-CHARGED TANK (SEE FIGURE 5)
A pre-charged water tank stores air and
water in separate compartments, sepa-
rated by a flexible bladder. The barrier
prevents the air from being absorbed
into the water. The bladder design also
allows the water to be acted on by
higher pressures for longer periods
than a conventional tank. Pre-charged
tanks have roughly twice the usable
capacity of a conventional tank with
equal volume. The air pressure in a pre-
charged tank must be checked periodi-
cally to insure it is at an acceptable
level (See Maintenance).
1. Shut off power to pump. Disconnect
and lock out power source.
2. Drain the tank. Open faucet nearest
the tank.
3. Insure tank is secured to the floor or
base.
4. Bolt pump to the floor or the
mounting bracket on tank.
5. Set air pressure in tank to desired
level. An air valve is located on the
side and will accept a standard fit-
ting from a bicycle pump or air line.
6. Install a valve and an isolator hose
between the tank and the house
plumbing. This will reduce the noise
level of the pump system and aid in
servicing.
7. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.
