Important Safety Instructions
SAVE THESE INSTRUCTIONS - This manual contains
important instructions that should be followed during
installation, operation, and maintenance of the product.
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!
indicates a hazard which, if not avoided, will
result in death or serious injury.
indicates a hazard which, if not avoided,
could result in death or serious injury.
indicates a hazard which, if not avoided,
could result in minor or moderate injury.
NOTICE addresses practices not related to
personal injury.
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.
California Proposition 65 Warning
This product and related accessories contain
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
1. Keep safety labels in good condition. Replace
missing or damaged safety labels.
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 a relief valve in pump supply line to tank, as
close to tank as possible.
6. BE SURE the 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.
Risk of 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 .
Installation
The tank listed below is pre-charged, or filled with
air at the factory, to 20 pounds per square inch (PSI)
(138kPa). When installing tank or if drawdown decreases
significantly, check as follows:
1. To check air charge in tank, shut off electric power to
pump, open faucet near tank, and drain completely.
2. At air valve, unscrew air valve protective cap and
check tank air pressure with tire gauge. See Chart 1
for the correct pressure setting. If needed, adjust the
tank pressure up or down. To do this, bleed air from
or add air to tank through valve on top of tank.
3. Use soap or liquid detergent to check for air leaks
around air valve. Continuous bubbling indicates
leak. If necessary, release air pressure and install
new core in air valve (same as used for automobile
tubeless tires.)
NOTICE Always set or check tank pre-charge with NO
WATER in tank and no water pressure in system. If you
have already pumped water before setting or checking
the pre-charge pressure, turn the pump off.
NOTICE Replace and tighten air valve protective cap
after pressure is adjusted correctly. Failure to replace
cap may allow loss of air pressure and lead to tank
waterlogging and diaphragm failure.
Chart I
When Pressure Switch Setting Is
Adjust Tank Precharge (PSI) To
20-40 PSI (138-276kPa)
18 (124kPa)
30-50 PSI (207-345kPa)
28 (193kPa)
40-60 PSI (276-414kPa)
38 (262kPa)
(The first number on the pressure switch is the
pump “ON” setting; the second number is the pump
“OFF” setting.)
This tank is designed to be supported by the system
piping either directly above the pump or in a convenient
location in the piping system as close to the pump
as possible.
NOTICE Tank capacity is different than drawdown. Tank
capacity is the actual physical volume of the sheet metal
that makes up the tank.
