Installation (By The Heating Engineer); Scope Of Delivery - Vaillant VEN 5/6 plus Notice D'emploi Et D'installation

3 Equipment and functional description
4 Installation
The cylinder operates according to the immersion heater
principle with a tubular heating element mounted inside
the inner tank. The tubular heating element in electric
domestic hot water cylinder models VEN 5/6 O and U has
a heating output of 2 kW. The temperature is controlled
by a controller comprising a sensor with capillary tube
linked to a mechanical switch that switches the electrical
circuit on and off based on the value set at the tempera-
ture selector. The temperature selector can be used to
select a temperature of up to a maximum of 85 °C.
The minimum value that can be selected is 7 °C. The
minimum temperature of 7 °C applies even with the tem-
perature selector set to "frost protection". This prevents
the unit from freezing in an unheated room. In order for
the "frost protection" function to operate, the unit must
not be disconnected from the power mains (do not
unplug the plug).
An indicator lamp is switched in parallel to the tubular
heating element.
This lamp lights up whenever the cylinder is being
heated.
Vaillant cylinders VEN 5 O and VEN 5 U are equipped
with a resettable safety temperature limiter, which inter-
rupts the electrical circuit in the event of a temperature
controller defect and switches off the tubular heating
element.
The volume of water in the cylinder expands with rising
temperature.
The excess expansion water drips out along the hot
water outlet pipe and out of the swivel spout of the
mixer tap. This process is both necessary and normal
and requires the use of low-pressure valves developed
specifically for these cylinders (see Vaillant's range of
accessories). These valves ensure a constant connection
between the cylinder content and the atmosphere even
with the hot water tap closed.
