Installation
1. Location
(1) There should be ample space around the pump and securing a large working space for maintenance
and
inspection
.
(2) Provide an enclosure around the pump or take some other effective measures to prevent
unauthorized personnel from coming near it.
(3) Install the pump in a location where it is near a water source, suction height (the height from the
suction surface to the centre of the pump) is low, and the length of the suction piping is short.
(4) Suction pipe should be as short as possible (check the suction total head at data sheet). In certain
cases, such as with hot water, suction head must be lower. To minimize suction pipe loss, excessive
use of elbows and valves should be avoided.
(5) Select an airy location with little dust and moisture. Ambient temperature should not exceed 40
℃
.
(6) Since water leaks can occur from the mechanical seals and gaskets in the pump, take precautions to
prevent water from leaking onto the floor or lower levels.
Note
After installation, have unneeded packaging disposed of by a specialist
disposal company.
