SITING OF THE PUMP
WARNINGS:
z
Do not run against a closed valve for periods longer than 5 minutes .
z
The water in and around the pump must not be allowed to freeze . This
will result in pump damage .
z
Do not under any circumstances use the supply cord fitted, as a
means to carry or lower the pump into position on installation . Attach
a rope sling to handle .
z
Do not allow plastic pump parts to come into contact with solder flux,
oil or cellulose based paints, paint thinners or strippers, acid based
descalents or aggressive cleaning agents .
z
When siting the pump ensure its base is raised slightly from the
bottom of the sump reducing the possibility of blocking the filter with
debris or drawing in small stones .
General
The pump must be installed in the vertical position and must be fully submerged at all
times when operating continuously to avoid overheating of the motor . However, when the
automatic float switch option is selected, the pump may be operated partially submerged
for short periods (see float switch operation section for further details) .
When siting the pumps in a location where organic or general debris is likely, ensure the
pump is placed on its base on a flat horizontal surface (eg . on a paving slab) to enable full
functionality of the inlet filter grille and to prevent the force of the pump from drawing in
small stones . This will result in pump damage .
FLOAT SWITCH
The pumps incorporate an integral automatic float switch which has two modes of
operation, auto and manual .
The float switch consists of a float which moves up and down on a vertical axis within a
housing .
Sump Size
The minimum possible sump size is
270 mm x 170 mm .
