For the correct operation of the
device, it is essential to install a
0.7 MPa safety unit (7 bar, light
OBLIGATION
series supplied as standard) on
the cold water inlet. Use only
connecting pipes (not supplied),
rigid and resistant to electrolysis
both at the inlet of cold water and
at the outlet of hot water from the
device.

•
Water can drip from the dis-
charge pipe of the overpres-
sure device; leave this pipe
ATTENTION
open to the atmosphere.
•
The decompression device
must be operated regularly
to remove limescale depos-
its and to check that it is not
blocked.
•
Connect a rubber hose to the
condensate drain, taking care
not to force too much so as
not to break the drain hose
itself.
6.7.1 Condensate drain connection
The condensate forming during heat pump operation flows
through a special drain pipe (½") that runs inside the insulation
casing and comes out the bottom of the equipment (fig. 57).
It must be connected to a duct so that the condensate can flow
regularly (example of installation fig. 58).
