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 to direct solar radiation
(the UV can destroy the plastic).
Heed the load-bearing capacity of the foundation, the filled LATENTO 500
weighs approx. 650 kg.
Keeping heat-losses as little as can be, place the LATENTO in the vicinity of the
reheating heat generator.
If possible, mount system in a heated room to minimize heat-losses
