49. Fill heating bath (water bath only)

Using de-ionized or distilled water needs to add 0.2 % of Borax (Na
(corrosion inhibitor)
Please note: The use of tabwater as heating media can lead to calcification which
can provoke crevice corrosion.Therefore the user is strongly recommended to
clean the heating bath with an adequate polish on a regular basis.
Heating bath water supply uses the vacuum/water distributor (refer to page 116).
Connect inlet end to fitting. Heating bath fill uses line (12) and is controlled by a solenoid valve
(12). Also refer to page 116.

50. Drain heating bath (water bath only)

The rear panel of the LABOROTA 20 control with water bath
features a drain valve (1). To close valve turn black lever
perpendicular to line.
This valve drains bath fill into a tank (not supplied).
Caution: Allow water to cool to ambient to avoid burns.
51. Condensate drain (water
bath only)
The LABOROTA 20 control (water
bath) features a condensate drain.
Water vapor from the hot bath is
condensed by the chiller coil (1) of
the condenser (2), and is collected in
a sump (3), which in turn is drained
through a nipple (4).
This nipple (4) accepts an elastic
hose (ID = 8 mm). The other end is
plugged in a collection tank.
52. Heating bath over
temperature protection
Once the over temperature protector responds (Over temperature Protection LED), allow the bath
to cool off and fix the problem.
Most possible reason: no water supply.
