Instructions on the hydraulic connections

7659613 - v02 - 08032017
Warning
Do not touch the refrigeration connection pipes
with your bare hands while the thermodynamic
water heater is running. Danger of burn or frost
injury.
Warning
Refrigerant fluid and pipes:
Use only R-134a refrigerant fluid to fill the sys­
tem.
Use tools and pipe components especially de­
signed for use with R-134a refrigerant fluid.
Use copper pipes deoxidised with phosphorus
to carry the refrigerant fluid.
Use beading to guarantee the tightness of the
connections.
Store the refrigerant connection pipes away
from dust and humidity (risk of damage to the
compressor).
Cover both ends of the pipes until the beading
process.
Do not use a load cylinder.
Note
The appliance is intended to be permanently
connected to the water mains.
Maximum / minimum water inlet pressure: See
chapter on Technical Specifications.
The pressure limiter device must be regularly
operated in order to remove limescale deposits
and ensure that it is not blocked.
Draining: Shut off the domestic cold water inlet.
Open a hot water tap in the installation and then
open the valve on the safety unit. When the wa­
ter stops flowing, the appliance has been
drained.
A pressure reducer (not provided) is necessary
when the supply pressure exceeds 80% of the
calibration of the safety valve or safety unit and
it must be located upstream of the appliance.
As water may flow out of the discharge pipe on
the pressure limiter device, the discharge pipe
must be kept clear and open.
Connect the pressure limiter device to a drain
pipe, kept open to the air, in a frost-free environ­
ment, and at a continuous downward gradient.
