If any of these points have been neglected
or if the water quality did not allow correct
treatment within the legal framework the
warranty will be null and void.
Use of a recirculation pump should be
avoided. Recirculating can cause a lack
of hot water and overconsumption of
energy. If using a recirculation pump, the piping
should be insulated and the pump should be
controlled by a timer or another system which
will prevent domestic hot water from circulating
continuously.
domestic hot water circuit:
- copper
- stainless steel
- brass
- plastic
If the materials used in the domestic hot water
circuit are incompatible, corrosion damage may
occur.
Consequently, the appliance should always be connected to copper
domestic hot water pipes
with a cast-iron or steel link, or with
dielectric connections
(not supplied) to avoid an iron/copper
galvanic bridge.
• Thoroughly flush the supply line piping before connecting the
appliance to the domestic installation so as not to introduce any
particles, metallic or other, into the appliance.
• Respect the standards in effect in the country of use, notably
hydraulic regulations and pressure safety regulations.
• The appliance must operate with water between 12
o
F and 30
o
F.
With particularly hard water (TH>25
o
F) it is advised to use a water
softener.
• If any of these points have been neglected the warranty will be
null and void (values given are for water at a temperature of
20
o
C). (See DTU-60-1 for more information).

- The condensates tube should not be directly connected to a
drain. It must lead off into open air in a siphon which has been
added and contains water.
- Do not use a lip seal.
- Do not use an elbow on the flexible hose.
