Table top version
The table top or bench-top type controller can be installed and connected directly on top of the
work bench or on laboratory table.
The table top version is supplied with a hose nozzle. The hose nozzle should be positioned in a
way that the connected vacuum hose cannot kink.
Attachment to Hei-VAP Rotary Evaporator
The Hei-VAC Control can be attached to Hei-VAP Rotary Evaporator directly.

Screw the pre-assembled metal plate that carries the vacuum valve to the back of the
evaporator with two screws:
