Frischwasser-Modul FriWa für die Trinkwasser-Erwärmung nach ...

Assembly instructions
Tipps and tricks:
For the assembly of the fresh water module you need (apart from the FriWa):
- as tools: level, folding rule, power drill with 10 mm masonry drill bit (for masonry assembly), flat
wrench n°13 for the fixation screws and n°31and n° 37 in order to hold against during the
assembly of the tubing and if necessary in order to retightening of the connecting nuts,
- a 2 nd person for the wall assembly.
Security equipment – please note:
The fresh water module is provided with a membrane security valve ¾“x1“ which meets the
appropriate regulations. The following advices need to be taken into consideration for the assembly
and the operation:
• The valve may not be impaired or rendered ineffective by blockages!
• Dirt collectors or other constrictions are not permitted between the collector (field) and the safety
valve.
• The diameter of the blow line must equal the diameter of the valve outlet; the max. length may
not exceed 2m. More than 2 bends are not permitted. If these maximum values (2 bends, 2m
line) are exceeded, the next largest size must be selected for the blow line. However, it must also
be noted that even with the larger size more than 3 bends and 4m line length are not permitted.
• If the blow line is routed in a drain pipe with a funnel, the size of the drain pipe must be at least
double that of the cross section of the valve inlet. You must also ensure that the blow line is laid
at a slope; the mouth must be open and visible and routed such that the blowing process does
not endanger persons.
Order of work steps:
- Determine the location of the system – possibly near the buffer storage. Install the FriWa
(see wall assembly).
- Connect the pipes according to the appropriate regulations (heating side at least DN25) and
connect the fresh water module (see connexion plan). In order to avoid any kind of
electrochemical corrosion, you absolutely need to follow the installation order while using
galvanised pipes and fittings! Tighten all the nuts and screwings.
- Charge qualified personell with the electrotechnical connexion of the system. (see
electrotechnical connexion). The corresponding regulations (VDE 0100 etc.) need to be
respected.
- Pressure test und commissioning of the system (see commissioning).
