Dear Customer!
The RETOMIX COMFORT vacuum mixer offers a high degree of user-friendliness with
programmable timing system that saves you having to check the mixing procedure each
time. The vacuum mixer employs a vacuum that yields homogenous and bubble-free
compounds. Pre- and main mixing time can be programmed individually with adjusted speed
according to applied material. The RETOMIX COMFORT allows mixing parameters to be
saved to 99 programs respectively under a name. Vacuum is generated with a maintenance-
free pump and can be individually adjusted. Speed is independent of amount mixed. The
vacuum mixer is available either as table or wall-mount unit.
Prior to installation of the device operating instructions and especially the safety instructions
must be read and followed by all personnel who use this device.
After having unpacked the device, please check carefully whether transportation damages of
any kind have occurred. If that is the case, the carrier or manufacturer must be notified within
3 days. The company will not be responsible for any damages found after that.
These operating instructions must be read and followed by all personnel who use this device.
To ensure quick access we recommend to keep it at a safe place near the device. In case of
loss it can be ordered at a nominal fee from the manufacturer.
