__291789_Munddusche_B6.book Seite 5 Montag, 9. Oktober 2017 4:50 16

DANGER! Risk of electric
shock

~ The battery charger is connect-

ed to the mains voltage, and
must therefore not be used in
the shower, in the bath, or over
wash basins filled with water.

~ The installation of a residual current de-

vice with a nominal trip current not ex­ceeding 30 mA in the building wiring
offers additional protection.
Contact a skilled electrician in this re­gard.
Do not start using the device if the device,

~

the battery charger or the mains power
cable shows visible damage, or if the de­vice has previously been dropped.

~ The mains power cable of this device

cannot be replaced. If the cable should
become damaged, the device itself must
be disposed of.
Only connect the mains plug to a proper-

~

ly installed and easily accessible wall
socket whose voltage corr esponds to the
specifications on the rating plate. The
wall socket must continue to be easily ac ­cessible after the device is plugged in.

~ Ensure that the mains power cable can-

not be caught or crushed, and that it
cannot be damaged by sharp edges or
hot points.

~ To fully disconnect the battery charger

from the mains power supply, pull out
the mains plug.

~ When removing the mains plug from the

wall socket, always pull the plug and
never the cable.

~ Disconnect the mains plug from the wall

socket.
… if there is a fault,
… when you are not using the device,
… before you clean the device and
… during thunderstorms.

~ To avoid any risk, do not make modifi-

cations to the device. Repairs must be

carried out by a specialist workshop or
the Service Centre.

~ When using an extension cable, this

must correspond to the applicable safe­ty regulations.

DANGER from battery

shine or heat. The ambient temperatu r e
should not be lower than 0 °C or higher
than +40 °C.

~ Charge the hand unit of the dental wa-

ter jet only with the original battery
charger.

~ Protect the battery against mechanical

damages. Fire hazard!

~ Should the electrolyte s olu tion leak out

of the battery, avoid contact with eyes,
mucous membranes and skin. Rinse im­mediately with plenty of clean water
and consult a doctor. The electrolyte
solution can cause irritation.

~ The device is provided with a lithium-

ion battery.

- The battery cannot be removed!

- This device must not be opened!

- The device with the installed battery
must be disposed of properly.

WARNING! Risk of material
damage

~ If you wish to attach the battery charger

to the wall, check what fixing material
is suitable. If in doubt, have the assem­bly performed by an expert.

~ Before drilling, check that there are no

water pipes or power cables in the wall
at the relevant point.

~ The battery charger is fitted with non-slip

silicon feet. As furniture is coated with a
variety of different varnishes and acryl­ics, and treated with different cleaning
agents, it cannot be completely ruled out
that components are contained in some
of these substances that could damage
and soften the plastic feet. If necessary,

GB

5

__291789_Munddusche_B6.book Seite 6 Montag, 9. Oktober 2017 4:50 16

place a non-slip mat under the battery
charger.
