How to use
Attaching the outlet hose

Screw the Outlet Elbow Connector into the Water Outlet

This pump features a Hose Connector that is compatible with multiple hose diameters: 38mm (1-1/2’’), 32mm (1-1/4’’) and 25mm (1’’)

Note: 38mm (1-1/2”) hose must be used to achieve maximum delivery capacity

Decide which hose diameter you are going to use and determine where on the Hose Connector this diameter hose is fastened

Cut off the smaller steps of the Hose Connector that are not needed, using a suitable knife (not included).This removes unnecessary flow restrictions and ensures maximum pump capacity and water flow

Fit the hose on to the Hose Connector and secure with a hose clip (not included)

Note: It is recommended to use stainless steel hose clips to prevent corrosion.
Setting up the pump

Attach a suitable rope to the Lifting Handle to lower the pump into the water, to adjust its position when submerged, and to lift the pump back out of the water
Locate a position for submerging the pump - where the float switch can move freely- if automatic operation is required
Ensure a safe path for the power cable, where it cannot be damaged, does not pose a hazard, and where it can safely reach the mains power supply (also see ‘Electrical connection’)
Observe the maximum head height (see ‘Specification’). Keep the hose as short and straight as possible. Ensure it does not kink as this would restrict the water flow

IMPORTANT: Kinked or otherwise obstructed hoses lead to reduced pump capacity and may lead to pump damage through overheating.
Adjusting the float switch

To adjust the cut-in and cut-out height, attach the Float Switch  cable to the Float Switch Lock at the required length

Submerging & lifting the pump

The pump must be submerged below the water level (see ‘Specification’)
Use the rope attached to the Lifting Handle to position the pump underwater. NEVER attempt to move the pump by pulling or manipulating the power cable
Ensure that the pump sits vertically on even ground. Check that the Water Inlets are not obscured in any way. If the bottom surface is soft, the pump should be supported on a flat object or be suspended using the rope attached to the handle
ONLY use the rope to lift the pump out of the water after use
