Important information and warnings!
Plumbing connections
The unit is a closed outlet water heater and is intended to operate at the pressure of the water mains, where the flow
of water is controlled by one or more taps or valves in the outlet line.
The unit can be installed into any type of commercial or residential construction as per the current local Plumbing
Standards.
It is mandatory for a water pressure limiting valve and a shutoff valve to be connected in series
with the unit‘s cold water inlet connection.
• The maximum rated operating line pressure is 1 MPA / 10 bar / 145 PSI.
• The minimum operating pressure is atmospheric pressure.
• The installation of a pressure limiting valve (a mandatory requirement) ensures that excess water pressure applied,
as result of water hammer and/or other circumstances, does not stress the appliance unduly.
• The in-line water pressure limiting valve must be rated at 5.0 BAR / 72.5 PSI / 500 KPA.
• The shutoff valve installed must not be a non-return valve.
• If the water heater is supplying a dishwasher or washing machine, a water hammer arrestor must be installed on
the outlet side of the water heater.

instructions outlined in this manual – specifically in this instance where the specified water pressure limiting valve and shutoff
valve type, as indicated, must be installed with this unit. If the unit is supplying a dishwasher or washing machine a water
hammer arrestor must be installed at the outlet side of the unit, failure to do so will void warranty.
