Safety 2

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 seri-

ous 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 and tank.

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 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.

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.

LIMITED WARRANTY

PENTAIR WATER warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free from
defects in material and workmanship for the Warranty Period shown below.

Product Warranty Period

Water Systems Products –

whichever occurs first:

jet pumps, small centrifugal pumps, 12 months from date of original installation, or
submersible pumps and 18 months from date of manufacture
related accessories

PENTEK INTELLIDRIVE 12 months from date of original installation, or

18 months from date of manufacture
Pro-Source™ Composite Tanks 5 years from date of original installation

Pro-Source™ Epoxy-Line T anks 3 years from date of or iginal installation
Sump/Sewage/Effluent Products 12 months from date of original installation, or

18 months from date of manufacture

Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication, improper
installation, or improper maintenance.Without limiting the foregoing, operating a three phase motor with single phase power through a
phase converter will void the warranty. Note also that three phase motors must be protected by three-leg, ambient compensated, extra­quick trip overload relays of the recommended size or the warranty is void.

Your only remedy, and PENTAIR WATER’s only duty, is that PENTAIR WATER repair or replace defective products (at PENTAIR WATER’s
choice).You must pay all labor and shipping charges associated with this warranty and must request warranty service through the
installing dealer as soon as a problem is discovered.No request for service will be accepted if received after the Warranty Period has
expired.This warranty is not transferable.

other rights which vary from state to state.

This warranty supersedes and replaces all previous warranty publications.

INSTALLATION

The tanks listed below are pre-charged, or filled with air
at the factory, as shown under “Product Information –
Pre-Charged Tanks,” below. 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

(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.

STANDARD TANK REPLACEMENT

When replacing a standard tank in a water system with a
pre-charged tank, no bleeder orifices or Air Volume
Control (AVC) are required. When sizing a pre-charged
tank to replace a standard tank, the tanks should have
equivalent drawdowns.

Hazardous voltage and hazardous pressure.
Disconnect all power to pump and bleed all pressure
from system before working on pump, tank, or piping.
