Fill the heating bath
CAUTION
If the level in the bath is too high, there is a risk that the heating bath
liquid will overflow when the flask is immersed.
• Property damages
• Loss of production
The device and surrounding areas can be severely contaminated by
escaping heating bath liquid!
Take the imprinted MIN/MAX markings on the inside of the heating bath
as a reference.
➜
Ensure that the evaporation flask is correctly mounted („Mount/remove evaporation flasks"
on page 79).
➜
Move the flask lift to the lower end position (see „Flask lift" on page 81).
➜
With the flask in the lower end position, fill the heating bath until the fluid reaches a level
between the MIN/MAX marks on the inside.
–
The maximum filling volume is 6 liters. Recommended filling volume: depending on
the flask size and the immersion angle: 2.2 l to 4.5 l.
Emptying the heating bath
CAUTION
The heating bath is designed for a maximum operating temperature of
210°C (using silicone oil). From a liquid temperature of 50 °C, there is a
risk of injury in the event of contact.
Always grip and hold the heating bath by the ergonomic safety handles
on the side!
Before emptying the heating bath, allow heated liquid to cool down to
below 50 °C.
Use suitable personal protective equipment (heat-resistant gloves, eye
protection, safety clothing) to empty the heating bath.
➜
Move the flask lift to the upper end position (see „Flask lift" on page 81).
➜
Disconnect the 7-pin connecting cable between the heating bath and the base unit.
➜
Remove the heating bath from the base plate of the base unit.
When changing the bath liquid, the heating bath must be thoroughly
cleaned and dried.
In particular, when changing from water to oil, make sure that the heating
bath temperature is only slowly and gradually augmented during restart
(recommendation: 10 °C), so that remaining water in the system can
evaporate until the process temperature is reached.
Heating bath overheat protection
The device is equipped with an autonomous overheat protection function that prevents the
heating bath from overheating. When reaching the maximum heating bath temperature, the
heating function is switched off by a mechanical switch To reset the safety function, follow
these steps:
