The appliance must be connected to the power supply taking the applicable installation instructions
and the relevant standards and regulations into consideration. It is particularly important to
observe the "Regulations for installing high-voltage systems with rated voltages up to 1000 V" and
regulations from the local power supply company. The appliances are only designed for permanent
connection to a 230 V ~ AC network. A contact gap of at least 3 mm (e.g. fuse) along the supply cable
must be provided for all poles at the installation location.
Electrical connection should be carried out by an authorised fitter only.
The storage water heater has a connecting cable (length approx. 1.00 m).
When delivered, the PSH Comfort / Comfort N wall-mounted storage water heaters are wired in the
way shown in circuit diagram 2.

Putting into operation

The specialist technician must monitor the appliance when it is put into operation and heats water
for the first time.
The water temperature can be adjusted as required (see Figure 1).
With low hot-water consumption or with very hard water, it is recommended to select the
energy-saving setting e (approx. 60 °C). The appliance reheats automatically at certain intervals or
when hot water is drawn.
It is only advisable to disconnect the storage water heater from the power supply if it is to remain
unused for a relatively long period of time. Heat loss is minimised by the high-quality heat-insulation
material made of CFC-free polyurethane foam.
If there is a risk of exposure to subzero temperatures, the stop valve must be closed and the storage
water heater then drained via the drain valve at the safety valve.

2.6 Maintenance
The outside of the storage water heater does not require any special maintenance. To clean, wipe
using a soft cloth or damp sponge only. Do not use any abrasive agents or aggressive detergents.
Caution! Always fully disconnect the appliance from the power supply before carrying out any
maintenance work.
To ensure a long service life, it is recommended to have a specialist technician inspect the
anti-corrosion anode (magnesium anode) in the appliance once per year. This check may need to be
carried out more frequently in areas with particularly aggressive water – ask the fitter or your local
water supply company for information.
The appliance is protected against overheating by a safety temperature limiter which interrupts all
phases. If the safety temperature limiter has been triggered, an authorised specialist technician is
required to carry out the repair work. After triggering, the safety temperature limiter can be reset by
pressing the red button under the switchbox cover.
