6. Operating procedures
6.1. Power connection
• Only connect the unit to a power socket with an earthing contact (PE – protective
earth)!
• The power supply plug serves as a safe disconnecting device from the line and
must always be easily accessible.
• Never operate the unit with a damaged mains power cable.
• Regularly check the mains power cables for damage.
• We disclaim all liability for damage caused by incorrect line voltages!
Make sure that the line voltage and frequency match the supply voltage
specified on the type plate.
6.2. Filling
Notice:
Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of
the liquid.
Guideline:
A volume change of 12 % per 100 °C temperature variation is to be considered.
Take care that no liquid enters the interior of the Cryo-Compact
Circulator .
Connect the tubing from the external system to the pump
connectors and check for leaks
Check to make sure that the drain tap (7) is closed.
Recommendation:
For filling, use for example an measuring jug with nuzzle.
Recommended maximum filling level with water as bath fluid:
30 mm below the tank rim
Recommended maximum filling level with bath oils:
40 mm below the tank rim
• Turn the mains switch (1) on
(Switching on - see page 27)
• Switch on unit by pressing the start/stop key
.
• Tempering fluid is pumped into the externally connected system.
Refill fluid up to recommended filling level.
