6.2 Mounting

Heed the following points when selecting the installation site for the LATENTO XW:
Frost-protected room.
Level, clean swept floor.
Do not subject the LATENTO XW to direct solar radiation
(the UV can destroy the plastic).
Heed the load-bearing capacity of the foundation, the filled LATENTO XW
weighs approx. 405/650/1250 (XW 300/500/1000).
Keeping heat-losses as little as can be, place the LATENTO XW in the vicinity of
the reheating heat generator.
If possible, mount system in a heated room to minimize heat-losses
(ENEV – Energy Saving Decree).
Note

6.3 Pipework

Caution
A thermal mixing valve (Item no. 878 700 021) must be installed to the hot water
outlet of the domestic water heat exchanger so as to prevent scalds. The hot water
heat exchanger should be 60 °C according to DIN EN 806-2 (June 2005).
Keeping heat-losses of the hot water tube as low as can be, we recommend you
to limit the thermal mixing valve to 45 °C – 50 °C hot water temperature.

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.
Heed the regulations of the local water distribution company
and relevant DIN standards when connecting. The connections
must be made pressure-tight. The component-tested safety instal-
lations have to be installed according to DIN 4753, Part 1,
para. 6.3-7 (safety valve, reflux valve, pressure reducing valve,
drainage, control and safety device).
