STP Series Turbomolecular Pump
INSTALLATION OF THE STP PUMP
2.3.2 STP pump installation positions
The STP pump can be installed vertically, horizontally, upside-down and/or slanted. (Depending
upon the pump model, the STP pump cannot be installed in some positions. Refer to "TECHNICAL
DATA" in the STP Pump Instruction Manual (B).)
Figure 15 - STP pump installation positions
When installing the STP pump in a horizontal or slanted position, it is recommended to install it so
that the direction of the outlet port is on a vertical or horizontal plane in the direction of the gravity.
This makes it possible to reduce the load on the magnetic bearing and the heat generated by the
STP pump.
