READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see
this symbol on your pump or in this manual,
look for one of the following signal words and be
alert to the potential for personal injury.
warns about hazards that will cause
serious personal injury, death or major property
damage if ignored.
warns about hazards that can cause
serious personal injury, death or major property
damage if ignored.
warns about hazards that will or can
cause minor personal injury or property damage if
ignored.
The label NOTICE indicates special instructions
which are important but not related to hazards.
Carefully read and follow all safety instructions in
this manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
1. Read this manual carefully. Failure to follow
these Instructions could cause serious bodily
injury and/or property damage.
2. Consult installer or licensed plumber for correct
relief valve. Install system according to local
codes.
3. Always test water from well for purity before
using. Check local health department for testing
procedure.
4. Before installing or servicing tank, BE SURE
pump electric power source is disconnected.
Release all water pressure before working on
tank or system. Release air pressure before
removing cover flange.
5. Install relief valve in pump supply line to tank,
as close to tank as possible.
6. BE SURE pump electrical circuit is properly
grounded.
7. Remove bleeder orifices, air volume controls or
other air charging devices in existing system.
8. DO NOT USE tank as a surge suppressor.
Hazardous pressure. To prevent
possible serious or fatal injury and/or damage to
equipment, system pressure must be less than
75 pounds per square inch (PSI) (517kPa) under
any circumstances. Failure to follow instruction
can result in tank explosion. If system discharge
pressure can exceed 75 PSI (517kPa), install a
relief valve capable of passing the full pump
volume at 75 PSI (517kPa).
Do not allow pump, tank, or piping
system to freeze. Freezing can severely damage
equipment and may lead to tank explosion and
serious injury. Allowing tank to freeze voids tank
warranty.

GENERAL INFORMATION

Tanks listed below are pre-charged, or filled with
air at the factory, to 40 pounds per square inch
(PSI) (276kPa). When installing tank, set tank pres-
sure according to Chart 1. To do this, bleed air from
or add air to tank through valve on top of tank.
NOTICE: Always set or check tank pre-charge with
NO WATER in tank or water pressure in system. If
you have already pumped water before setting or
checking pre-charge pressure, turn pump off. Open
faucet until there is no more water pressure. Set
pre-charge in tank according to Chart 1, then close
faucet and turn pump back on.
NOTICE: Replace and tighten air valve cap after
pressure is adjusted correctly. Failure to replace air
cap may allow loss of air pressure and lead to tank
waterlogging and bladder failure.
CHART I
When Pressure Switch
Setting Is
20-40 PSI (138-276 kPa)
30-50 PSI (207-345 kPa)
40-60 PSI (276-414 kPa)
(The first number on the pressure switch is the
pump on setting; the second number is the pump
off setting.)
Drawdown is the actual amount of usable water
available from when the tank is full to when the
pump turns on.
NOTICE: Tank capacity is different than drawdown.
Tank capacity is the actual physical volume of the
tank.
Reduce Tank
Precharge (PSI) To
18 (124 kPa)
28 (193 kPa)
38 (262 kPa)
