Dear Customer!
The RETOMIX EASY vacuum mixer is the entry-level model of the REITEL vacuum mixer
product family. Vacuum is generated with a high-quality and durable vacuum pump. Easy
handling due to automatic starting of the vacuum pump as soon as the mixing bowl is held
under the bowl support. Required mixing time is easily set with the manual timer. You simply
need a socket to plug in for operation.
The RETOMIX EASY is perfectly suitable to mix plaster, investment material and alginates. A
filter system prevents contamination and damage to the motor and the vacuum pump.
Vacuum intensity is adjustable. The device is available as wall-mounted or benchtop 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.
