pump base, or control unit (see Figure 12). DO NOT apply face on convex parts, such as the outlet 
port or connectors by ropes. Doing so may the pump to fall, or deform and damage the parts. 
A crane 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. When lifting the pump, use 2 or more ropes.
