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 could cause
serious personal injury, death or major property damage
if ignored.
warns about hazards that could 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 100 pounds per
square inch (PSI) (689kPa) under any circumstances.
Failure to follow instruction can result in tank blowup.
If system discharge pressure can exceed 100 PSI
(689kPa), install a relief valve capable of passing the full
pump volume at 100 PSI (689kPa).
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 pressure 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.

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.)
Pre-charged storage tanks can be connected together to
increase the drawdown. Drawdown is the actual amount
of usable water available from when the tank is full to
when the pump turns on. Installing two tanks of same
size will double the drawdown supply, three tanks will
triple the drawdown supply, (Figure 1). Locate pressure
switch as shown. Tank and pressure switch cannot be
more than 10' (3M) apart.

NOTICE: Tank capacity is different than drawdown. Tank
capacity is the actual physical volume of the sheet metal
that makes up the tank.
