Bosch Tronic 3000T ES2.5 Installation Manual And Operating Instructions page 4

Explanation of symbols and safety information
NOTICE:
▶ The manufacturer cannot be
responsible for the damages caused
by improper installation or by failure
to follow instructions in this manual.
Comply with the installation
instructions before completing
electric connection.
NOTICE:
▶ The thermostat has been pre-set at
the factory at a temperature equal or
below 60 °C (140 °F).
DANGER:
▶ Hydrogen gas can be produced in a
hot water system served by this
heater that has not been used for a
long period of time (generally 2 weeks
or more). Hydrogen gas is extremely
flammable. To reduce the risk of
injury under these conditions, it is
recommended that the hot water
faucet be opened for several minutes
at the kitchen sink before using any
electrical appliance connected to the
hot water system. If hydrogen gas is
present, there will probably be an
4
unusual sound such as air escaping
through the pipe as the water begins
to flow. There should be no smoking
or open flame near the faucet at the
time it is open.
CAUTION:
▶ Any water heater should be installed
in such a manner that if it should leak,
the resulting flow of water will not
cause damage to the area in which it is
installed. National Plumbing codes
require a drain pan for any water
heater installation. Failure to install
one is the sole responsibility of owner
and/or installer. Reference UPC 2006
(Uniform Plumbing Code) Section
508.1, or IPC 2006 (International
Plumbing Code) Section 504.7.
CAUTION:
▶ Prior to connecting the power supply,
ensure tank is full of water and system
is purged of air.
NOTICE:
▶ Tank failure due to neglecting to
maintain the anode rod is not covered
under warranty (see Section 5
Maintenance).
