4.3 Installation site
Position the domestic hot water cylinder as near as pos-
sible to the heater to prevent unnecessary heat loss.
Place the cylinder in a suitable location in the building,
paying attention to the following:
– The tundish discharge pipe must be installed with
a minimum downward slope of 1:200 and must end
in a safe and visible place.
– The installation surface must be flat and capable
of bearing the weight of the full cylinder.
– The installation site must not be at risk of frost.
If necessary, install a frost protection thermostat.
– The control system for the installed cylinder thermostat
beneath the front plate must be easily accessible to the
operator.
– There must be sufficient space for mounting, maintai-
ning and replacing the electric immersion heater.
– The floor must be even.
– There must be sufficient space for installing, maintaining
and replacing the expansion vessel.
> Choose a cylinder installation site that allows the potable
water and heating lines to be laid in an appropriate man-
ner.
> To prevent energy losses in accordance with current buil-
ding regulations, provide all system pipes with thermal
insulation.
