2 LOCATION - GENERAL
2.11
Access:
For emergencies and maintenance the pump must be
easily
accessible.
2.12 Do not run against a closed valve for periods longer than 5 minutes.
The water in and around the pump must not be allowed to freeze.
This will result in pump damage.
2.13 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.
2.14
Pump position:
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 (see Fig. 2).
2.15 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).
2.16 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.
2.17
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.
2.18
Sump Size:
The minimum possible sump
size is 270 mm x 170 mm.
