WARNING 
 
The STP pumps are heavy products. Observe national laws/regulations, safety 
standards and manufacturers instructions when lifting the STP pump. 
Lifting devices must be used when lifting or moving the STP pump. 
The STP pumps are heavy products (Refer to Section 2, "TECHNICAL DATA" for the mass of the 
STP pump). Use a crane or other appropriate means sufficient enough to withstand the load when 
lifting the STP pump of 18 kg or more. 
Lift the STP pump with eyebolt, eye nut or a similar tool that uses the fitting hole attached to the inlet 
port flange. When lifting the pump, use 2 or more ropes. (see Figure 11) 
A crane, an eyebolt, and an eye nut 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, or eye 
nut which confirms to ISO03266. 
Always lift the STP pump in stable places free of excessive shock or vibration to prevent it from 
shaking or dropping. 
Care should be taken not to scratch the flange of the STP pump. Before installing the STP pump, 
check that there are no scratches on the surface.
