WARNING Hot surfaces!
Risk of scalding and burns.
Allow the glass equipment to cool down.
Allow media to cool down.
WARNING Hazardous materials and solvents!
There are risks posed by the leakage of hazardous substances and
solvents from locations that are not properly sealed.
Check whether all screw caps have been tightened properly at the
threads to seal them off.
Route all PTFE tubes into the vessels intended for them and fasten
them securely to the vessel.
Do not expose operating personnel to harmful vapors or gases.
Extract waste air using a vapor outlet.
Ensure that the separator for the power supply is easily accessible at
all times.
Cleaning agents
To ensure thorough cleaning, replace contaminated cleaning agents
during the process for clean cleaning agents, if necessary.
Ensure that the device is in the Sensor-Mode and in the operating state process
stopped.
Allow residue pump and condensate pump to continue running for an additional
10 seconds until the residue and condensate circuits are drained.
Product storage circuit
Route the PTFE tube which leads to the product storage vessel into a vessel
containing cleaning agents (e.g. solvent).
Create a vacuum.
Now follow the chapters entitled Start-Up - Set parameters to convey cleaning
agent into the flask.
Remove the PTFE tube from the vessel containing cleaning agents and direct into the
atmosphere. Air will be conveyed into the evaporating flask.
Wait 10 seconds until the product storage circuit is emptied.
Condensate circuit
To create atmospheric pressure within the evaporator system, ventilate the rotary
evaporator.
Hei-VAP: Remove the vacuum attachment or vacuum tube (glassware set G1) from
the uppermost condenser opening; Hei-VAP Industrial: Remove vacuum fitting.
Then press the start/stop key. The message please preset flask-level manually
appears in the display. Disregard this message.
Use the uppermost condenser opening to fill in the cleaning agent. The cleaning agent
will be discharged by the condensate pump.
Wait 10 seconds until the cleaning agent has drained into the collector.
To trigger the level sensor of the collector manually, position your index finger on the
level sensor (between the collector and the metal piece onto which the level sensor is
fastened). The orange level sensor LED will light up and the collector will be drained.
Repeat this process until the collector is completely empty.
Wait 10 seconds until the condensate circuit is emptied.
Residue circuit
Pump cleaning agents, as outlined under „Product storage circuit” into the
evaporating flask.
Route the PTFE tube which leads to the residue vessel into an empty vessel.
Press the „drain residue” key. Cleaning agent will be drained by the residue pump.
Wait 10 seconds until the residue circuit is emptied.
Flask sensor
Remove the flask sensor out of the evaporating flask and glassware set and clean
with a cloth drenched with cleaning agent.
Disassembly
WARNING Hot surfaces!
Risk of scalding and burns.
Allow the glass equipment to cool down.
Allow media to cool down.
