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 illing (see the table “Technical 
speciications”) must be taken into consideration.
The position of the screws required for installation is shown in Figure 4 and 5. 
The mounting brackets for vertical 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.

Risk of damage! If the water pressure is higher than 5 bar, a pressure reducer must be itted in 
the cold-water supply line.
Caution: The appliance is under pressure. During the heating process, expansion water will 
drip from the safety valve. If water continues to drip when heating is completed, please inform 
your contractor.

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 3.

Risk of damage! 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.
Regularly check the function of the safety valve. 
The safety valve protects the storage heater from excessive increases in pressure. The EWH Basis 
storage heaters are itted with a safety valve without non-return valve as an accessory. The EWH Basis 
N wall-mounted storage heaters are itted 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 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.

Risk of damage! Never connect the storage heater to the electrical power supply without irst 
checking whether the storage heater is actually illed with water.
