THIS IS THE SAFETY ALERT SYMBOL. IT IS USED TO ALERT YOU TO POTENTIAL PERSONAL INJURY AND OTHER
HAZARDS. OBEY ALL SAFETY MESSAGES THAT FOLLOW THIS SYMBOL TO REDUCE THE RISK OF PERSONAL
INJURY AS WELL AS PROPERTY DAMAGE.

READ CAREFULLY THE PRODUCT

INSTALLATION & OPERATION INSTRUCTIONS.
FAILURE TO FOLLOW THE INSTRUCTIONS AND WARNINGS IN THE
MANUAL MAY RESULT IN SERIOUS OR FATAL INJURY AND/OR
PROPERTY DAMAGE, AND WILL VOID THE PRODUCT WARRANTY.
THIS PRODUCT MUST BE INSTALLED BY A LICENSED
PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL AND STATE
CODES AND REGULATIONS. IN THE ABSENCE OF SUCH CODES,
FOLLOW THE CURRENT EDITIONS OF THE NATIONAL PLUMBING
CODE AND NATIONAL ELECTRIC CODE, AS APPLICABLE.
EXPLOSION OR RUPTURE HAZARD. THE WELL TANK MUST BE
OPERATED SO THAT THE PRESSURE DOES NOT EXCEED THE
MAXIMUM WORKING PRESSURE.

EXPLOSION HAZARD. Failure to follow the

instructions in the product manual can cause a
rupture or explosion; possibly causing serious or fatal injury, leaking or
flooding and/or property damage.

Use only with a potable water system. Do not

operate in a setting with freezing temperatures or
where the temperature can exceed 130°F and do not exceed the
maximum working pressure specified for this Product in the Manual.
Mount vertically only.

Chlorine & Aggressive Water: The water quality

can significantly influence the life of this Product.
You should test for corrosive elements, acidity, total solids and other
relevant contaminants, including chlorine and treat your water appropriately
to insure satisfactory performance and prevent premature failure.

causing serious or fatal injury, leaking or flooding and/or property damage.
To minimize risk, a licensed professional must install and periodically
inspect and service the Product. A drip pan connected to an adequate
drain must be installed if leaking or flooding could cause property damage.
Do not locate in an area where leakage of the tank or connections could
cause property damage to the area adjacent to the appliance or to lower
floors of the structure.

Product Manual, whichever is less. Do not expose Product to freezing
temperatures or temperatures in excess of 130°F. Do not adjust the pre­charge or re-pressurize this Product except for any adjustments required
at the time of initial installation, especially if Product is corroded,
damaged or has diminished integrity. Adjustments to pre-charge must
be done at ambient temperature only. Failure to properly size the
Product or follow these instructions may result in excessive strain on the

ELECTROCUTION AND EXPLOSION HAZARD.

Before work is performed on the tank, turn off the
power to the pump and release all water pressure in the tank and
pumping system.

How a Well Tank Works

1. As the pump fills the tank with water, the air above the

diaphragm is compressed. This increases the pressure in the
tank and causes the pressure switch to turn off the pump.

2. When water is used, it is drawn from the tank and the pressure

inside the tank decreases. The reduced pressure starts the
pump and refills the tank.

The amount of water delivered between pump cycles is called
drawdown. The larger the well tank, the greater the drawdown
capacity, the less the pump needs to run. This saves energy and

money, and extends pump life. Larger tank sizes also increase the
water storage volume to provide more consistent water pressure.
