Installation

2.1

Wall mounting

Fit the small storage water heaters in a frost-proof room next to the connection point.
The EWH mini/mini N is intended for above-basin installation only.
The EWH mini U/mini U N is intended for below-basin installation only.
The materials used to mount the appliance must be selected according to the strength of the wall. The
combined weight of the storage water heaters and their water filling (see Table 1) must be taken into
consideration. The position of the screws required for installation is shown in Figure 1.

Water connection 2

2.2
The appliance must be connected to the water system by an authorised specialist technician, taking the
applicable installation instructions and the relevant standards and regulations into consideration.
The water connection is unvented (pressure-proof) to supply several drawing points or vented
(unpressurised) to supply one drawing point.
The wall-mounted storage water heater is suitable for connection to plastic pipe systems.
Information on connecting to plastic pipe systems: In the event of malfunctions, temperatures of up to
95 °C (max. 0.6 MPa) can occur. Any plastic pipes used must be designed for these conditions.
If the water pressure is higher than 5 bar, a diaphragm safety valve with pressure reducer must be
fitted.
Before connecting the storage water heater to the water pipe, rinse out the pipe thoroughly to prevent
any foreign objects from entering the storage water heater or the safety components.
It is recommended to install the storage water heater in the way shown in Figure 2.
In the case of pressure-proof connection, the storage water heater must always be installed
together with an approved diaphragm safety valve.
The safety information given in the installation instructions for the safety valve must be observed.
The safety valve must be checked to ensure that it is functioning correctly.
The safety valve used for pressure-proof installation protects the storage water heater from excessive
increases in pressure. The EWH mini and mini U wall-mounted storage water heaters are fitted with a
safety valve without non-return valve as an accessory. The EWH mini N and mini U N wall-mounted
storage water heaters are fitted with a safety valve with non-return valve as an accessory. The safety
valve must be actuated at regular intervals to prevent it from jamming as a result of furring (lime
deposits).
The dripping-water outlet of the safety valve must always remain open to the atmosphere.
The dripping-water outlet must be connected to a downward-pointing drain pipe which ensures
unobstructed drainage of the water.
Filling: After connecting the storage water heater, open the stop valve.
Then open the hot-water tap. The storage water heater is full when water is discharged from the
hot-water tap.
Then close the outlet tap and check the system for leaks.
