Hydraulic Connection - Atlantic Explorer Installations- Und Bedienungsanleitung

• This water heater is fitted with a thermostat with an operating
temperature of above 60 °C at its maximum position, capable
of reducing the growth of legionella bacteria in the tank.
Caution! Above 50 °C, water could cause immediate scalding.
Check the water temperature before taking a bath or shower.
A new safety device which conforms to current standards (EN 1487
in Europe), pressure 0.7 MPa (7 bar) and size 3/4" (20/27)
in diameter must be fitted. The safety valve must be protected
from frost.
A pressure reducer (not supplied) is required if the supply pressure
is greater than 0.5 MPa (5 bar) and will be installed on the main
supply pipe.
Connect the safety device to a discharge pipe, kept in the open air,
in a frost-free environment, continuously sloping downwards
to drain off the heat-expanded water or to allow for drainage of the
water heater.
No components (stop valve, pressure reducer, etc.) must
be positioned between the safety unit and the water heater cold
water branch connection.
For products with a coil: The working pressure of the heat
exchanger circuit must not exceed 0.3 MPa (3 bar), its temperature
must not exceed 100 °C. Do not connect the hot water branch
connection directly to the copper pipes. It must be equipped with
a dielectric union (supplied with the appliance).
In the event of corrosion to the threads of hot water branch
connections not equipped with this protection, our warranty
is invalid.
