PREPARATION (cont.)Preparing the Universal AdaptorThe universal adaptor (3) is designed to fit various sizes of pipes and fittings. Prepare the universal adaptor (3) as required for the accessory, seeoptions A, B & C below. The universal adaptor (3) allows a range ofdifferent diameter hose/tube to be fitted (Fig. 3).

A) To fit a 25mm (1’’) tap adaptor (temporary application only) Cut the universal adaptor (3) using a hack saw (notincluded) (Fig. 4). It is now ready to be fitted with a 25mm (1’’) tap adaptor and flexible tubing (not included)(Fig. 5).

B) To fit a 25mm (1’’) rigid pipe or flexible tubing(temporary or permanent application) No cutting of the universal adaptor (3) is required (Fig. 6).It is now ready to be fitted with a 25mm (1’’) rigid pipe orflexible tubing (not included) (Fig. 7).

C) To fit a 32mm (11/4’’) rigid pipe or flexible tubing(temporary or permanent application) Cut the universal adaptor (3) using a hack saw (notincluded) (Fig. 8). It is now ready to be fitted with a 32mm(11/4’’) rigid pipe or flexible tubing (not included) (Fig. 9).

NOTE: To use the pump in permanent installations with rigid pipes, install a non-return valve to avoidthe fluid being re-circulated once the pump has stopped. NOTE: After temporary applications, the pump should be cleaned with clean water after each use,see "Maintenance" section for more information.

SET-UP & INSTALLATION1. Screw the L-shape connector (4) into the pump housing (2) by rotating

in a clockwise direction (Fig. 10).NOTE: Make sure the L-shape connector (4) is firmly tightened so that the O-ring is compressed between the pump housing (2) and the L-shapeconnector (4). This ensures no leakage will occur at this point.

2. Screw the prepared universal adaptor (3) clockwise onto the L-shapeconnector (4) (hose/tube/tap adaptor should not be connected at thisstage) (Fig. 11).

NOTE: Make sure the universal adaptor (3) is firmly tightened so that the O-ring of the L shaped connector (4) is compressed between the universaladaptor (3) and the L shaped connector (4). This ensures no water or airleakage will occur at this point.

3. Securely attach the hose/tube/tap adaptor (not included) to the universaladaptor (3) (Fig. 12) (see the section "Preparing the Universal Adaptor").

NOTE: Due to the high water pressure generated by the pump it isrecommended to use a hose clamp (not included) when fitting a flexiblehose or tube (available from your local Bunnings Warehouse). This securesthe hose or tube and further prevents it from becoming removed from theuniversal adaptor (3) during operation (Fig. 13).

NOTE: Before submerging the pump in water, unwrap the power cable (10)and ensure the plug is clear of any damp locations.

4. To immerse the pump in deep water, use a rope (not included) andsecure it to the handle (1) (Fig. 14). Set the pump in the desired positionwithin the work area/tank.

NOTE: The vent valve (7) is used to allow air to escape from the pump bodywhen submerging the pump so no priming is required.

SET-UP & INSTALLATION (cont.)NOTE: The pump has a pre-set float switch (6). To change the setting,reduce or increase the length of the float switch cable (9) by inserting it in thefloat switch adjuster (8) (Fig. 15 & 16).When the float switch cable (9) is able to move freely (float switch adjustor (8) isnot in use), the pump will function down to a water depth of 150mm. Restrictingthe length of the float switch cable (9) using the float switch adjustor (8), resultsin the pump ceasing operation at higher water depths.The length of the float switch cable (9) between the float switch adjustor (8)and the float switch (6) must be at least 100mm in order for the float switch(6) to activate and de-activate.

5. When the float switch (6) is adjusted as you require, use the rope (notincluded) to immerse the pump back into the body of water.

OPERATION1. When the float switch (6) is 30° higher than horizontal (start up level) or

above the handle (1), the pump will turn ‘on’ and operate (water depth of530mm) (Fig. 17).

ATTENTION: The pump runs as soon as the float switch (6) reaches thestart-up level.

2. When the float switch (6) is 30° lower than the horizontal or below thehandle (1), the pump will turn ‘off’ and will not operate (water depth ofapproximately 150mm) (Fig. 18). You can alternatively, manually turn thepump off at the mains power.

ATTENTION: If you wish to use the pump down to the minimum water depth of70mm, the float switch (6) will need to be operated manually. The pump can bemanually turned “on” by lifting the float switch (6) to the required level.CAUTION: You must observe the pump at all times when operating manually.NOTE: If you manually turn the pump off, be aware of the location of yourhose or tube (not included). If it is at a lower point than the pump, the water will continue to ‘siphon’out, unless a non-return valve (not included) is used in the hose or tube and turned off.

Turning On and Off1. Insert the plug into the mains power socket (Fig. 19). Avoid using

extension cords as this can lead to a voltage drop which may causepower loss and overheating.

2. Switch on the mains power to commence operation.3. To cease operation, turn off the mains power. The pump will also stop

operation automatically once the float switch (6) reaches the minimumwater depth (150mm).

HINTS WHEN USING THE PUMP• The maximum pumping rate only occurs when using the largest diameter hose or tube possible, if

smaller diameter hoses or tubes are used, the rate will reduce relative to the size of thehose/tube. Try to use discharge pipes which have a larger diameter than the discharge outlet.

• Running the pump with no water flowing through leads to increased wear and is notrecommended. The pump must be immediately unplugged as soon as water stops flowingthrough.

The pump will automatically switch off in the event of overheating due to the built-in thermaloverload protector. After cooling down, the motor automatically switches on again.

• When disconnecting the pump from the mains power supply, do not pull by the power cable (10).Using 3 fingers around the 3 pin power plug, gently pull and disconnect from the mains power.

MAINTENANCEIn ordinary conditions, the pump does not require any maintenance. Make sure the pump is disconnected from electric power supply before performing maintenance procedures.

Cleaning the Pump HousingUse a moist cloth to wipe down the pump housing (2). Allow to dry thoroughly before storing in a drylocation that is protected from bad weather conditions.

Cleaning the Suction BaseGently hose down with low pressured water. Allow to dry thoroughly before storing.

Power CableFor all submersible pumps, a H07RN-F cable is required to be fitted. Contact Commercial Electriccustomer service for replacement cable.
