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.
This Product, like most Products under pressure,
may over time corrode, weaken and burst or explode,
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.
EXPLOSION OR RUPTURE HAZARD A relief valve
must be installed to prevent pressure in excess of
local code requirement or maximum working pressure designated in the
Product Manual, whichever is less. Do not expose Product to freezing
temperatures or temperatures in excess of 130°F. Do not adjust the pre-
charge 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
system, lead to Product failure, serious or fatal personal injury, leakage
and/or property damage.
This product can expose you to chemicals including
lead, which is known to the State of California to
cause cancer and birth defects or other reproductive harm. For more
information go to www.P65Warnings.ca.gov.
NOTE: Inspect for shipping damage and notify freight carrier or store where purchased immediately if damage is present. To avoid risk of personal
injury and property damage, if the product appears to be malfunctioning or shows signs of corrosion, call a licensed professional immediately. Current
copies of the Product manual can be viewed at www.amtrol.com. Use proper safety equipment when installing.
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.
