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, periodically inspect 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 appliance or to lower floors of
the structure.
RUPTURE OR EXPLOSION 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 200° F. Do not adjust the pre-charge or
re-pressure this Product except for any adjustments required at the time of
initial installation, especially if Product is corroded, damaged or with
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.
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.
Note: Inspect for shipping damage and notify freight carrier or store where
purchased immediately if damage present. To avoid risk of personal injury
and property damage, if the product appears to be malfunctioning or

copies of the Product manual can be viewed at www.waterworkerdiy.com.
Use proper safety equipment when installing.
Use only with potable water system. Do not operate in
a setting with freezing temperatures or where the
temperature can exceed 200° F and do not exceed the maximum working
pressure specified for this Product.
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, 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.
FAILURE TO PROPERLY SEAL VALVE CAP WILL
RESULT IN LOSS OF PRECHARGE CAUSING PRODUCT
TO FAIL.
PRE-INSTALLATION
1. Remove valve cap and adjust air charge to match cold water supply
pressure. Replace cap tightly to prevent air loss.
2. Identify an installation point on the cold water line between the water
heater and backflow preventor or other one-way device.
INSTALLATION
G5 and G12 with Saddle Valve (Use with Copper Pipe Only)
1. Shut the cold water supply off and relieve water pressure.
2. Assemble the saddle valve to the piping as shown. Using wrench
provided, tighten the saddle valve to pierce the line and compress the
gasket seal. Alternate screws while tightening.
3. Install the tank using pipe sealing tape or paste.
4. Open the cold water supply and check for leaks.
MAINTENANCE
The installation should be inspected annually and more often as the system
ages. Check for signs of corrosion and indicators of excessive water
pressure levels, if any are present the unit should be replaced.
G5L and G12L Direct Connection
1. Shut the cold water supply off and relieve water pressure.
2. Install a pipe tee with a 3/4" NPTF threaded connection.
3. Thread the tank into the tee using pipe sealing tape or paste.
4. Open the cold water supply and check for leaks.
See reverse side for warranty information.
