Operating Instructions and Parts Manual
Installation
(Continued)
Make sure the pump has adequate
ventilation. the surrounding
temperature should not exceed 100˚F
(38˚C) or nuisance tripping of thermal
overload protector on the motor may
occur.
PUMP PIPING INSTallaTION
use new pipe for best results. Iron,
copper or PVC pipe may be used.
to avoid strain on the pump when
using iron or copper pipe, provide
independent supports for both suction
and discharge 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 discharge piping if length is
over 50 feet.
figure 1 - Pipe Installation
SUCTION PIPING
Install foot valve
or strainer screen
over intake of suction piping.
never use pipe smaller than 1-1/4"
diameter 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
1-1/4" nPt.
Do not install
suction piping near
swimming areas.

DISCharGE PIPING (fIGUrE 2)
Install a 3/4" pipe cross (sold separately)
in the pump discharge. Plug top of
pipe cross with 3/4" nPt pipe plug (sold
separately). Insert tank tubing into side
opening of pipe cross. Insert pipe into
remaining side opening for connection
to home water supply line.

water and pressurized air in the same
compartment. When full, the tank
contains approximately 2/3 water and
1/3 compressed air. this type of tank

1. Shut off power to pump. Disconnect
CISteRn
and lock out power source.
2. Drain the tank. opening faucet
nearest tank is recommended.
3. Insure tank is secured to the floor or
base.
4. Bolt pump to the floor or the
mounting bracket on tank.
5. Install air volume control on tank.
6. Connect the tube from the air
volume 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
waterlogged.
7. 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.
8. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.

this will prevent trapping air in the

PRe-CHaRGeD tanK (See FIGuRe 5)
a pre-charged water tank stores air
and water in separate compartments,
separated 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 periodically 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.
