Operation - Yardworks YW1000DW Instruction Manual

1. 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 of
530mm) (Fig. 17).
Attention: The pump runs as soon as the float switch (6) reaches the
start-up level.
2. When the float switch (6) is 30° lower than the horizontal or below the handle
(1), the pump will turn 'off' and will not operate (water depth of approximately
150mm) (Fig. 18). You can alternatively, manually turn the pump off at the
mains power.
Attention: If you wish to use the pump down to the minimum water depth of
70mm, the float switch (6) will need to be operated manually. The pump can be
manually 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 your hose 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 Off
1. Insert the plug into the mains power socket (Fig. 19). Avoid using extension
cords as this can lead to a voltage drop which may cause power 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 minimum water
depth (150mm).
HINTS WHEN USING THE PUMP
1. 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 the hose/tube. Try to use
discharge pipes which have a larger diameter than the discharge outlet.
2. Running the pump with no water flowing through leads to increased wear and is not recommended. The pump
must be immediately unplugged as soon as water stops flowing through.
The pump will automatically switch off in the event of overheating due to the built-in thermal overload
protector. After cooling down, the motor automatically switches on again.
3. 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.
