When installing the STP pump to the vacuum equipment in upside-down position, the STP-iS2207 
series can be loft with the eyebolts (M8) attached to the screw holes for securing the base. (see 
Figure 15) 
A crane and eyebolts due to lifting operations should withstand the load of five times or more the 
weight of the STP pump, and rope should be seven time or more. Use an eyebolt which confirms to 
ISO03266. When lifting the pump, use 2 or more ropes.
