PLEASE READ ALL INSTRUCTIONS BEFORE INSTALLING YOUR NEW
GLOBAL WATER SOLUTIONS (GWS) TANK
CAUTIONS AND WARNINGS
⚠ CAUTION: To prevent personal injury, ensure all water pressure is released from the pressure
system prior to work being performed. Ensure pumps are disconnected and/or electrically isolated.
⚠ WARNING: It is strongly recommended that the system is protected by a suitable pressure relief
valve set at or below the maximum tank pressure rating. Failure to install a relief valve may result
in tank explosion in the event of a system malfunction or over pressurization, resulting in property
damage, serious personal injury or death.
⚠ WARNING: If the pressure tank leaks or shows signs of corrosion or damage do not use it.
⚠ WARNING: If the expansion tank is heavier than 30 kgs, proper equipment such as lifting crane
etc. should be used in order to avoid damage to the tank and personnel.
These instructions have been prepared to acquaint you with the correct method of installing and
operating your GWS pressure tank. We urge you to study this document carefully and follow all of
the recommendations. In the event of installation difficulties or the need for further advice, you should
contact the dealer from whom you purchased the system or the nearest GWS sales office.
