Use instructions supplied with the individual system components.
Valves and fittings must be sealed with PTFE
tape if compression seals are not included.
6.9 Connect the water supply
Water supply pressure range 2 - 5 bar.
If the mains water pressure is below 2 bar a fault could arise.
If the mains water pressure exceeds 5 bar a 3.5 bar water pressure
reducing valve must be fitted. Failure to do so could result in the
appliance overfilling.
To avoid damage, do not use any solder connections whilst pipes
are connected to the appliance.
Instanta cannot be held responsible for any appliance malfunction if the
water pressure is not within the range stated. If in doubt, consult your
water supply company.

water supply for servicing or repair, as well as a back-flow prevention
device to prevent water from the appliance re-entering the mains water
supply.

practice, see page 17.
