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 leaking could cause property
damage to the area adjacent to the tank 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 450°F.
Replace the Product if corroded, damaged or with diminished integrity.
Failure to properly size the product or follow these instructions may result
in excessive strain on the system and may lead to product failure, serious
or fatal personal injury, leakage, and/or property damage.
FOR USE IN CLOSED HYDRONIC SYSTEMS ONLY. Do not install on
domestic water systems, or in open heating systems. Corrosion and tank
failure may result.

Operation
1. The HWBT models are designed to add thermal mass to non-
potable, closed, hot water systems helping minimize boiler
cycling that occurs during no/low domestic load conditions.
2. Water temperature not to exceed 450°F.
3. System pressure is not to exceed the maximum working
pressure of the tank.
Warranty

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.
Welding to the pressure vessel boundary will
void the ASME rating.
Leaking, corrosion or indications of damage are
signs of an impending serious failure of the
buffer tank. Periodically inspect for damage and if noted the product
must be serviced or replaced. Failure to follow these instructions
could result in serious personal injury or death and
property damage.
Water temperature above 100°F can be very
hazardous. Allow system water temperature to
cool down below 100°F before blowing down this product. Failure to
follow these instructions could result in serious personal injury or
death and property damage.
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. At least once every
3 years or if discharge is present, a licensed contractor should inspect the
temperature and pressure relief valve and replace if corrosion is evident
or the valve does not function. FAILURE TO INSPECT THIS VALVE AS
DIRECTED COULD RESULT IN UNSAFE TEMPERATURE OR
PRESSURE BUILD-UP WHICH CAN RESULT IN PRODUCT FAILURE,
SERIOUS INJURY OR DEATH AND/OR SEVERE PROPERTY
DAMAGE AND VOID THE PRODUCT WARRANTY.
