Transport
WARNING
Risk of injury from carrying heavy loads and inadequately securing
loads for transport!
▶ Use suitable means of transport.
▶ Secure the cylinder to prevent it falling.
▶ Move packed cylinder with a sack truck and lashing strap
( Fig. 6, page 69).
-or-
▶ Move unpacked cylinder with a transport net, during handling,
protect connections against possible damage.

Mounting method
The cylinder is delivered fully assembled.
▶ Check that the cylinder is complete and undamaged.
5.1
Installation location
NOTICE
Risk of damage from inadequate load-bearing capacity of the
installation surface or unsuitable floor surface!
▶ Ensure that the installation surface is level and offers sufficient load-
bearing capacity.
▶ Install the cylinder in a dry frost-free interior.
▶ If there is any danger of water accumulating on the floor of the
installation location: place the cylinder on a plinth.
▶ Observe the minimum wall clearances inside the installation room
( Fig. 5, page 69).
5.2
Setting up the cylinder
▶ Remove packaging.
▶ Remove protective caps.
▶ Set up and align the cylinder ( Fig. 8/ 9 page 69).
▶ Apply Teflon tape or Teflon string. ( Fig. 10, page 70).
5.3
Hydraulic connections
WARNING
Risk of fire from soldering and welding!
▶ Take appropriate safety measures when soldering and welding as the
thermal insulation is combustible (e.g. cover thermal insulation).
▶ Check cylinder jacket for damage after completing work.
WARNING
Risk of injury from contaminated water!
Work carried out without due care for cleanliness pollutes the water.
▶ Install and equip the cylinder hygienically in accordance with national
standards and guidelines.
5.3.1
Establishing the hydraulic connection to the cylinder
System schematics with all recommended valves and taps in the graphic
part ( Fig. 11, page 70).
▶ Use installation material that is temperature-resistant up to 160°C
(320 °F).
▶ Never use open, vented expansion vessels.
▶ Use metal connection fittings in DHW heating systems with plastic lines.
▶ Size the drain line in accordance with the connection.
▶ To facilitate blow-down, never install elbows in the drain line.
▶ Keep primary line as short as possible and insulate it.
▶ If using a non-return valve in the cold water supply: Install a pressure
relief valve between the non-return valve and cold water inlet.
▶ Install a pressure reducer in the cold water supply if the static
pressure in the system is in excess of 5 bar.
▶ Seal all unused connections.
