2) INSTALLATION
Site in a dry, well ventilated and weather
!
proof location with an ambient
temperature of no more than 40 C.
Locate on a solid flat surface ensuring the
!
shaft is in a horizontal position.
Ensure that the diameter of the suction
!
pipe is at least the size of the pump
suction inlet. If the suction depth exceeds
4 meters then a one size larger diameter pipe. If the suction depth
exceeds 4 meters then a one size larger diameter pipe should be used,
though for maximum pump performance suction height should be
minimised.
