WARNING!
Improper installation, adjustment, alteration, service or maintenance
can cause property damage, serious bodily injury or death. Read
instructions completely before proceeding with installation. Only
qualified personnel may install or service this equipment in accor-
dance with local codes and ordinances.
This Expansion Tank is designed and intended for water storage at
a maximum pressure of 150psi (10.3 bar). A maximum instantaneous

in death.
Do not exceed 80psi (5.5 bar) air charge. Air charge pressures
exceeding 80psi (5.5 bar) could become hazardous and will void any
and all warranties, either written or implied. Failure to follow these
instructions will result in the possibility of property damage, serious
bodily injury or death.

or other responsibility for personal injury or property damage resulting
from improper use, installation or operation of this tank or the system
