The EPJ Instantaneous Water Heater provides hot water in the domestic household, a public facility, a labora-
tory, a workshop, or virtually anywhere where there is a demand for instant hot water. Turning the hot water tap
on, automatically starts up the heater (a red light on the heater's outer case comes on). Water is heated instantly
as a result. The temperature of heated water depends on the rate of flow: the greater the flow, the lower the tem-
perature. Turning the hot water off, shuts the appliance.
The heater features:
- tubular heating coils that assure maximum safety
- materials resistant to corrosion and chemically inactive with water (copper, brass, stainless steel, plastic)
This appliance will work with
the attached tap set only.
The tap set works as an air vent
and therefore, cannot be con-
nected to any valve or a connec-
tor that is not recommended by
the manufacturer.
