Installation

2.1

Wall mounting

Fit the wall-mounted storage heaters EWH 30 ... 200 Basis / Basis N with the water connections at the
bottom in a frost-proof room next to the connection point.
The materials used to mount the appliance must be selected according to the strength of the wall. The
combined weight of the storage heaters and their water filling (see the table "Technical specifications")
must be taken into consideration.
The position of the screws required for installation is shown in Figure 5 and 6.
Depending on the appliance type, the mounting brackets for vertical installation and mounting brackets
for horizontal installation are an integral part of the storage heater.
2.2

Water connection

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 closed (pressure-proof) and supplies several drawing points.
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 pressure reducer must be fitted in the cold-water
supply line.
Before connecting the storage heater to the water pipe, rinse out the pipe thoroughly to prevent any
foreign objects from entering the storage heater or the safety equipment.
It is recommended to install the storage heater in the way shown in Figure 10.
The storage heater must always be installed together with an approved diaphragm safety valve.
The safety information given in the installation instructions for the diaphragm safety valve must be
observed.
The safety valve must be checked to ensure that it is functioning correctly.
The safety valve protects the storage heater from excessive increases in pressure. The EWH Basis storage
heaters are fitted with a safety valve without non-return valve as an accessory. The EWH Basis N
wall-mounted storage 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 (for EWH Basis N appliances) 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 heater, open the stop valve. Then open the hot-water tap. The
storage heater is full when water is discharged from the hot-water tap.
Then close the outlet tap and check the system for leaks.
Never connect the storage heater to the electrical power supply without first checking whether
the storage heater is actually filled with water.
