6.3. Filling / Draining
Filling
 Recommended maximum filling level is 25 mm below the
tank rim
 Minimum filling level: approx. 1 cm above the perforated
stainless steel base plate.
Note:
The working filling level depends on size and number of the
items (fixtures) to be placed inside.
The recommended procedure is to fill the water bath only
partially, place the items (fixtures) inside and then correct
the filling level (adding or removing liquid) as required.
Draining
 Press the mains switch to turn the water bath off
 TW2
Take the water bath in both hands and pour out the bath
liquid into a suitable vessel.
 TW8, TW12, TW20
Place a suitable collecting bucket or tub underneath the
unit for draining the used bath liquid.
 To drain the liquid open the drainage screw (11) on the
side of the water bath.
 After the liquid has been fully drained, securely tighten
the drainage screw (11) again.
Warning
:
There are thermal dangers when opening the bath cover:
Burn, scald, hot steam, hot parts and surfaces that can be touched.
 Do not drain the bath fluid while it is hot!
 Check the temperature of the bath fluid prior to draining
(by switching the unit on for a short moment, for example).
Recommendation:
Use the water bath cover to keep temperature losses to a
minimum. This is especially important for working
temperatures above 60 C.
