20 / 34 Hydro Water Baths 09/2020
9 Water Circulation (only Water Baths models H 8 A und Typ H 16 A)
The circulation system ensures an optimized temperature distri-
bution throughout the whole Water Bath. It is operated by an
electric motor with stirring magnet, flanged to the Water Bath
basin, that transmits its torque to a PTFE-coated stirrer. The
stirrer draws the water to the middle of the basin and then moves
it back to all sides. The electric motor of the water circulation is
activated via the main switch.
10 Maintenance and Support
Caution! Prior to maintenance and cleaning let the Water Bath cool down!
If required, the water in the Water Bath can be drained through the drain cock at
the back of the Water Bath.
Caution: Danger of burns!
Make sure to prevent liquids coming into contact with cable connections or the
inside of the electrical appliance. Except when descaling the unit (see chapter 10.7)
disconnect the unit from the mains by pulling the plug, thus separating the Water
Bath all-pole from the mains. Repairs of the electrical system may only be carried
out by a trained electrician.
Exchanging the internal unit fuses
10.1
In direct proximity of the mains connection cable's screw joint, the mains fuses F1 and F2
(see chapter 13) are fixed on a fuse holder in the inside of the Water Bath. In order to
check and to exchange the fuses, the bottom plate of the Water Bath must be removed.
The fuses may only be exchanged against fuses of identical specifications. For information
on the fuses used please view the label next to the fuses as well as the spare parts list (see
chapter 15).
In addition to the following chapters 10.2 to 10.6 please observe by all means the information in these
operating instructions, chapter 8.4, on resetting alarm reports of the function control.
