1.1 Description of the unit
The STIEBEL ELTRON IP pressureless
(open) instantaneous water heater is a
device for heating water for a shower.
The unit switches the power on once the
ow volume reach 1.5-2 l/min.
The “Power” light (e) indicates that the
unit is switched on. If the temperature
adjustment rotary (c) switch is turned to
the lelf, it is possible to take a cold shower
(the heater will not be switched on).
Model IP has a built-in booster pump.
Switch (b) is a push-on/push-o switch for
the pump function. When the inlet water
pressure is too low for a good shower ow,
this booster pump can be switched“ON” to
provide stronger shower spray.
The IP is tted with an overheating protection
device. In the event of overheating the heating
power will be cut o.

valve is closed, (such as applying soap to
the body), then valve opened again, high
water temperature may occur. To avoid risk
of scalding, stay away from the shower head
discharge zone momentarily.
Thermostat cut-o is a service
case only for qualied techni cian
1.4 Care and Maintenance
All that is needed for cleaning of the housing
is a damp cloth. Do not use any abrasive
cleaning agents or agent containing solvents.
Maintenance work may only be

1.5 Hot water capacity
The hot water capacity depends on the
power of the unit, the cold water temperature,
and the ow volume.
1.6 Regulations and Provisions
- Regulations of the local power supply
company should be observed.
- Regulations of the water supply company
should be observed
- Read & study the technical data.
- Install the unit vertically on the wall.
