5 Operating Voltage
The Water Bath must be connected to a correctly installed shock-proof socket. The Water Bath
is a protection class I electrical appliance, a connection to the earth conductor (PE) must be
ensured. For information on the required mains fuse please view Technical Data, chapter 12 of
this manual. Further reference for connection to the mains can be found in chapter 14 of this
manual.
The electrical connection must ensure an all-pole separation from the mains at any time. The mains
connection cable must not touch any hot surfaces of the unit. It may not lead underneath the unit.
The main switch of the Water Bath must be off (position O). The voltage on the nameplate (at the
back of the unit) must be identical to the mains voltage. If they are identical, connect the unit to the
mains.
6 Filling water into the Water Bath
Use the Water Bath only with tap water. Even stainless steel will corrode when used improperly. Use nei-
ther ferruginous nor chlorous water, in order to prevent rust formation and pitting. Using distilled or deion-
ised water will also ultimately lead to corrosion in the Water Bath and must, therefore, be avoided.
Media, such as oil, acid, or other additives, not approved by LAUDA-GFL, to prevent bacteria contamina-
tion (chlorine or copper sulphate), may lead to damages to the Water Bath basin, the screw connections of the ducts and
the heating element. Such damages are not covered by guarantee.
Before initiation, the Water Bath must be filled with water. For maximum filling quantities please refer to the Technical
Data, chapter 12 of this manual. Make sure that the drain cock at the back of the unit is locked (handle must be in a 90°
angle to the drain cock). Open the lid of the unit and fill in water at least up to the marking "min" (approx. 50 mm above
the perforated floor) and not exceeding the marking "max" (approx. 50 mm below the upper bath rim).
