Safety Considerations and Symbol Descriptions

1.2

Safety considerations

Read all instructions before installing. Perform the steps in the indicated
sequence. Have the tank inspected by a trained service technician at
least once every year. Failure to comply with these instructions can
result in severe, possibly fatal, personal injury as well as damage to
property and equipment.
Installation and servicing
▶ Risk of fire from soldering and brazing!
Take appropriate protective measures when soldering and brazing as
the insulation is flammable, for example, cover the insulation.
▶ Ensure that only a licensed contractor installs or services the tank.
▶ Use installation material with adequate temperature stability.
Installation and commissioning
▶ In the Commonwealth of Massachusetts, the tank must be installed by
a licensed plumber.
▶ The electrical power must be connected by a licensed electrician.
The wiring diagram must be followed.
▶ Do not install this device in rooms with a high moisture level
(e.g. bathrooms, saunas).
Function
▶ To ensure that the tank functions properly, heed these installation and
maintenance instructions.
▶ Never close the blow-off line of the T&P safety valve. For safety
reasons, water may escape during heating.
Danger from electric shock
▶ Ensure that only an authorized contractor performs electrical work.
▶ Before performing electrical work, disconnect the power and secure
the unit against unintentional reconnection.
▶ Ensure the system has been disconnected from the power supply.
Risk of scalding at the hot water draw-off point
▶ When the tank is in operation, temperatures in excess of 122 °F
(50 °C) can occur. To limit the temperature at the tap, install a
thermostatic DHW mixing valve.
▶ Water heated for washing the laundry, dishes and for other cleaning
purposes can cause scalding and permanent injuries.
▶ Children, elderly, and handicapped persons are more likely to be
permanently injured by hot water. Never leave such individuals in the
tub or shower unattended under any circumstances. Children must
not be allowed to operate hot water faucets themselves or to fill a
bathtub.
▶ If the building has occupants in the above groups who operate hot
water faucets, or state laws / local ordinances stipulate specific water
temperatures, take the following precautions:
– Use the lowest possible temperature setting.
– To prevent scalding, install a tempering device, such as an
automatic mixing valve, at hot water tap or water heater. Select and
install the automatic mixing valve in accordance with the valve
manufacturer's recommendations and instructions.
▶ Water exiting from drain valves can be extremely hot. To avoid
injuries:
– Check that all connections are tight.
– Direct exiting water away from people.
▶ Measures must be taken to protect against excessive temperature and
pressure! Installation of a T&P safety valve is required.
