Pipework - Würth IVT Latento 500 Notice De Montage

Note For operation with electrical heating element (878 700 039):
The screwing of the electrical heating element into the LATENTO
storage tank should take place before its filling and piping.
In areas with low room height it can be necessary to tilt the
LATENTO storage tank in order to insert the electrical heating
element.

5.4 Pipework

Caution Heed the relevant DIN standards when connecting. The connec-
tions must be made pressure-tight. The heating installation must
be pressure-checked and flushed due to DIN EN 14336. The
component-tested safety installations have to be in stalled
according to DIN 4753, Part 1, para. 6.3-7 (safety valve,
reflux valve, pressure reducing valve, drainage, control
and safety device).
Note The heat exchanger must only be charged with a pressure of
max. 15 bar. The heat exchanger would expand if the water
pressure exceeded 15 bar. The LATENTO 500 might get dama-
ged because of this. Due to DIN EN 12502, there is a max.
chloride concentration of water of 53 mg/l (warm water)
respectively, to be kept. Otherwise there may be hole-/grid-
corrosion in the heat exchanger.
