Okofen 600, Installation Manual

Page: 9 / 32

The following points must be observed:
1 . Installing the heating system:
• The cylinder may only be connected to closed-circuit heating systems.
• The cylinder may only be connected to approved piping systems.
• ÖkoFEN recommends the installation of a DHW mixer as scalding protection.
• The piping must be insulated sufficiently to reduce cooling losses.
• The building clearance for installing and removing the cylinder must be
ensured.
• The cylinder must be installed in such a way that it can be shut off and emp-
tied.
• ÖkoFEN recommends use of a pressure regulator in the DHW building con-
nection.
• A fine filter (backwash filter) must be installed in the DHW building connec-
tion.
• The pH value must be at least 5.0.
• Materials that emit chlorides (e.g. seals) are prohibited.
• In the case of connection to galvanised pipes, no iron or zinc particles may be
washed into the DHW heat exchanger. It is advisable to install a dirt trap.
• If a corrosion protection additive is employed, it must be compatible with
stainless steel.
2 . Loading the accumulator
Optionally, the speed of this pump can be controlled by the boiler controller. Pro-
vision mustbe made for a safety pressure relief valve (3 bar) in the accumulator
loading circuit.
