SENSOR POSITIONING
Sensor sleeves are available on the buffer tank for the insertion of the sensor (to regulate the system).
Where E-sockets are not used via these, a 1½" external thread to ½" internal thread reducer can be fitter
with any immersion or sensor sleeve.
COMMISSIONING
The installation and commissioning should be carried out only by approved installation companies, which
take responsibility for using proper equipment.
PREPARATIONS
*
All the connections, including those which are assembled at the factory (E-socket, flange, anode, etc.),
must be inspected when commissioning for leaks and sealed again if any leak is found (if necessary drain
the buffer tank, disassemble and re-seal). This is not a guarantee, warranty or product liability. Please
have a filling hose ready.
1. Filling
Connect the buffer tank via the filling hose to a water line. Flush all pipes and the buffer tank, then drain
the flushing water. Now, the buffer tank is filled again with water until water flows from the warm water
tap without bubbles. This process may take about 15–30 minutes, depending on the size and water flow.
Then close the water tap. Then continue to fill the buffer tank until the operating pressure is reached.
Smooth tube heat exchangers should be rinsed properly prior to initial installation (recommendation:
install a dirt filter).
2. Leak Test
Water heaters should be checked for leaks before commissioning. As soon as possible after the cold
water pressure test it is necessary to test whether the system remains sealed at the highest temperature
by heating to the maximum operating temperature. Where there is a drop in pressure a leak in the
system must be assumed.
CORROSION PROTECTION
All surfaces of the drinking water storage tank of the TWS, TLS, WP-TWS and HL-TWS product series that
come into contact with service water are quality-assured by a quality glass enamelling in accordance with
DVGW 511 and DIN 4753. The stainless steel storage tanks EDS are made of stainless steel AISI 316L (EN
1.4404). The storage tanks are equipped with a protective magnesium anode in accordance with DIN
4753; possibly enclosed.
Magnesium or external current anodes are used as protective anodes for enamelled drinking water
storage tanks. Only impressed current anodes approved by the manufacturer may be used. It should
be noted that magnesium anodes only work technically from an electrical conductivity (25 ° water)
with> 200μSv and external current anodes from> 100μSv. The electrical conductivity (25 ° water) is to be
requested from the local water supplier and the corresponding corrosion protection is to be built up on
it. This value has to be checked regularly for changes and the corrosion protection has to be adjusted.
It is important that for both variants (magnesium and external current anodes) an undisturbed current
flow between anode and steel wall is ensured via a conductive connection.
If a smooth-tube heat exchanger is not used when the storage tank is in operation, it must be filled
with a suitable anti-corrosion agent (e.g. glycol mixture) or connected in series with the heating circuit
heat exchanger on the heating side. The smooth tube heat exchanger must not be closed on both sides
(pressure expansion).
