I. General Information
IMPORTANT INFORMATION – READ CAREFULLY
NOTE: The equipment shall be installed in accordance with those installation regulations required in the area where the
installation is to be made. These regulations shall be carefully followed in all cases. Authorities having jurisdiction shall be
consulted before installations are made.
All wiring on storage tanks shall be in accordance with the National Electrical Code and/or local regulations.
WARNING
!
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury, or loss
of life. Read and understand the entire manual before attempting installation, start-up, operation, or service. Installation
and service must be performed only by an experienced, skilled installer or service agency.
This storage tank contains very hot water under high pressure. Do not unscrew any pipe fittings or attempt to disconnect
any components of this storage tank without positively assuring that the water is cool and has no pressure. Always wear
protective clothing and equipment when installing, starting up or servicing this storage tank to prevent scalding injuries.
Do not rely on the pressure and temperature gauges to determine the temperature and pressure of the storage tank. This
storage tank contains components that become very hot when the boiler is operating. Do not touch any components un-
less they are cool.
Failure to follow all instructions in the proper order can cause personal injury or death. Read all instructions, including all
those contained in component manufacturers’ manuals before installing, starting up, operating, maintaining, or servicing
the storage tank.
CAUTION
!
To reduce the risk of excessive pressures and temperatures in this storage tank, install temperature and pressure
protective equipment required by local codes but no less than a combination temperature relief valve certified by a
nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials,
as meeting the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-
latest edition. This valve must be marked with a maximum set pressure not to exceed the marked working pressure of
the storage tank. Install the valve into an opening provide and marked for this purpose in the storage tank, and orient it
or provide tubing so that any discharge from the valve will exit only within 6 inches above, or at any distance below, the
structural floor, and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size
under any circumstances.
Improper water quality will reduce the life of the storage tank. Hard water, sediment, high or low PH and high levels of
chlorides in the domestic water should be avoided. Be sure that PH levels fall between 6 and 8 and dissolved chlorides
are less than 100 ppm. A filter must be used where sediment is greater than 5 microns in size in the water supplied to
the unit. A water softening system is recommended for areas with hard water. In cases where water quality is unknown, a
qualified water treatment expert should be consulted.
NOTICE: Damage to tanks caused by improper water quality is not covered under the warranty.
