General safety instructions

Installation, start-up, repairs and maintenance must
be performed to a professional standard.
The unit must only be installed by an approved heating
engineer. The existing regulations, rules and guidelines
must be observed when doing so. Start-up, repairs and
maintenance must also be carried out by an approved
technician.
Defective units must be reported to the supplier
before installation.
> If the unit is damaged in any way, inform your sup-
plier before it is connected.
Avoid material damage caused by incorrect
installation.
The Vaillant electric domestic hot water cylinder is an
open-vented cylinder and must be used only in conjunc-
tion with a low-pressure valve.
> Use only low-pressure valves.
Ensure anti-corrosion protection.
The units may only be used to heat up potable water.
Damage to the unit due to corrosion cannot be excluded
if the water does not comply with the legal requirements
for drinking water.
> Before installation, check that the water quality meets
the legal requirements for drinking water.
Fill the cylinder in good time (heating engineer's
responsibility).
> Before initial start-up or after draining, always fill the
electric domestic hot water cylinder before the mains
plug is plugged in.
Avoid leaks.
> Have leaks repaired by an approved heating engineer.
Risk of death from electric shock from live supply
lines and connections.
During all work on the open unit, particularly on electri-
cal lines and connections, there is a risk of death from
electric shock.
> Do not carry out any work on the unit yourself.
> Inform your heating engineer if your electric domestic
hot water cylinder is not working correctly.
Avoid risk of being scalded by hot water.
The outlet valves and escaping water may be as hot as
85 °C.
> When using the electric domestic hot water cylinder,
be aware of the risk of scalding from high outlet tem-
peratures.
> There is a particular risk of scalding whenever the
electric domestic hot water cylinder is set to "hot
water".

Safety and warning information 2
> For normal usage, set the temperature selector of the
electric domestic hot water cylinder to economy
mode "E", which maintains a temperature of approxi-
mately 60 °C.
Avoid material damage inside the unit caused by poor
quality water.
An electric domestic hot water cylinder must be used
exclusively to heat up potable water.
This drinking water must meet specific legal require-
ments for quality. Otherwise, it would not be possible
to rule out the risk of corrosion inside the unit.
> Consult an approved heating engineer if you have
any doubt as to the requirements for water quality.
Avoid frost damage (operator's responsibility).
Freezing conditions can cause damage to the unit.
> You should therefore ensure that the electric domes-
tic hot water cylinder always remains in operation
during freezing conditions and that all rooms are
sufficiently heated.
Even if rooms, or the whole dwelling, are not in use for
certain periods, the heating must remain in operation.
Frost protection is only active while the unit is con-
nected to the power supply. The temperature selector
must be set to "frost protection". The unit must be con-
nected to the power supply.
The unit settings are unable to provide frost protection
for supply pipes or outlet valves.
If the electric domestic hot water cylinder is placed out
of operation for a relatively long period of time in an
unheated room (e.g. during a winter holiday), the electric
domestic hot water cylinder must be disconnected from
the mains power supply and drained completely.
> Consult an approved heating engineer if you have any
doubt as to requirements.
> Ensure that your electric domestic hot water cylinder
is installed in a permanently frost-free room.
Avoid frost damage (heating engineer's responsibility).
Freezing conditions can cause damage to the unit.
> Please inform the operator about the possibilities
of frost protection.
> Tell the operator that the frost protection function
will be unavailable if the electric domestic hot water
cylinder is completely switched off.
> Inform the operator that the electric domestic hot
water cylinder must be disconnected from the mains
power supply and drained completely if the domestic
hot water cylinder is to be placed out of operation for
a relatively long period of time in an unheated room
where there is a risk of frost
> Inform the operator that the unit settings are unable
to provide frost protection for supply pipes or outlet
valves.
