Safety instructions
Read all instructions before installing. Perform the steps in the indicated
sequence. Have the DHW 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 safety measures when soldering and brazing as the
thermal insulation is flammable.
▶ Ensure that only a licensed contractor installs or services the DHW
tank.
▶ Use installation material with adequate temperature stability.
Forbidden:
Connection of the potentiostat for an impressed current anode to the
magnesium anode installed in a storage tank is absolutely forbidden!
This would destroy the tank! The warranty would be voided.
Installation and commissioning
▶ Have an electrician connect the electrical system. 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
▶ Only electricians may work on the electrical system.
▶ Before performing electrical work, disconnect the power cable 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 DHW 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 mentally impaired 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.
The chart below shows the relationship between water temperature and
time until there is a risk of scalding. It can be used as the basis for
determining the safest water temperature for your application.
Warnings in this document are indicated by a warning
triangle printed against a gray background.
Keywords at the start of a warning indicate the type and
seriousness of the ensuing risk if measures to prevent
the risk are not taken.
This symbol indicates important information where
there is no risk to people or property.
