▶ Check that the DHW cylinder is complete and undamaged.
5.1

Installation location

NOTICE: System damage due to inadequate load-bearing
capacity of the installation area or unsuitable substrate!
▶ Ensure that the installation area is level and offers
sufficient load-bearing capacity.
If there is a danger that water may collect on the floor of the installation
site:
▶ Place DHW cylinder on a plinth.
▶ Position the DHW cylinder in dry internal areas that are free from the
risk of frost.
▶ Observe the minimum room height ( tab. 11, page 102 and
tab. 12, page 103) and the minimum wall clearances in the
installation location ( Fig. 10, page 106).

Hydraulic connection

WARNING: Risk of fire from soldering and welding!
▶ When soldering or welding, apply suitable protective
measures (e.g. cover the thermal insulation), since
the thermal insulation is combustible.
WARNING: Risk to health through contaminated water!
Work carried out without due care for cleanliness
contaminates the potable water.
▶ Install and equip the DHW cylinder hygienically in
accordance with national standards and guidelines.
5.3.1

Connecting the DHW cylinder on the water side

System example with all recommended valves and taps ( Fig. 22,
page 110 [WS...] and Fig. 21, page 109 [W...]).
▶ Use installation material that is heat-resistant to 160 °C (320 °F).
▶ Never use open expansion vessels.
▶ Use metal connection fittings in potable water heating systems with
plastic pipes.
▶ Size the drain line in accordance with the connection.
▶ To facilitate blow-down, never install elbows in the drain pipe.
▶ If using a non-return valve in the supply pipe to the cold water inlet:
install a pressure relief valve between the non-return valve and the
cold water inlet.
▶ Install a pressure reducer, if the static pressure in the system is > 5
bar.
▶ Seal all non-used connections.
▶ Only fill DHW cylinders with potable water.
▶ During filling, open the highest positioned tap ( Fig. 24,
page 110).
