PLEASE READ ALL INSTRUCTIONS AND
WARNINGS BEFORE INSTALLING YOUR
NEW GLOBAL WATER SOLUTIONS PRES-
SURE TANK
These instructions have been prepared to acquaint you with
the correct method of installing and operating your GWS
pressure tank. Please read and follow these instructions and
heed any warnings to ensure safety and maximum product
performance. In the event of installation difficulties or need for
further advice, please contact the nearest GWS sales office or
dealer.
The following instructions and warnings are subject to
periodic updates and should be regularly reviewed on
the website www.gwsusa.com/support for important
safety information and instruction updates.
OPERATION
This pressure tank has been designed to store and deliver
potable water under pressure in a domestic water system.
It features a diaphragm or membrane design that keeps the
system water in a safe and contaminant-free chamber for
pressurized water supply between pump cycles.
Without a pressurized storage tank, a domestic water system's
pump would turn on every time there is a demand for water,
even if the demand is small. This frequent on/off cycling shortens
the useful life of the pump. Pressure tanks are designed to store
water when the pump is running and then deliver pressurized
water to the system when the pump is shut off (See Fig. 1). A
properly sized tank will store at least one gallon of water for
every gallon per minute (GPM) of pump capacity. This allows for
fewer pump starts and longer run times which maximizes the life
and efficiency of the pump system.

EXPLOSION HAZARD
This pressure tank is designed for water
storage at a maximum pressure of 150 psi and a maximum
temperature of 194° F. The system must be protected by
a suitable pressure relief valve set at a maximum of 100
psi. This pressure tank is shipped with a pre-charge of 38
psi and any adjustment to the pre-charge must be done prior
to installation and at ambient temperature. Do not adjust the
pre-charge of this tank if the product is corroded or damaged
or shows any signs of diminished integrity. The maximum
allowable pre-charge in this pressure tank is 80 psi. Failure
to follow these instructions may result in serious injury,
death and/or property damage.
P R O P E R P L A C E M E N T O F TA N K
This pressure tank should be installed
in a covered, dry area. This tank must not be installed in
a location that is subject to freezing or where it can rub or
vibrate against a hard surface. The tank must be installed in
a suitable location to prevent water damage due to leaks and
have means for adequate drainage. The manufacturer of
this product is not liable or responsible for any water
damage associated with the installation and/or failure
of this product. Failure to follow these instructions may
result in serious injury, death and/or property damage.
FO R P OTA B L E WAT E R U S E O N LY
This pressure tank is intended for use
with potable water systems only. Use with non-potable water
or any other fluid may be dangerous and will void the warranty.
This product's performance and lifespan can significantly be
impacted by aggressive water conditions. A water test should
be conducted specifically looking for corrosive water, acids
and other relevant water contaminants which, if present, must
be treated appropriately. The system piping must be properly
grounded to earth. A dielectric union may be required in the
system. Failure to follow these instructions may result in
serious injury, death and/or property damage.
