4. Before use
• Read through thewhole manual and make sure you understand it, learn where thecontrols
are and how they work.
• Acquaint yourself with thepump and its functions before you start using it; learn what to do
to quickly minimize potential risks that may arise.
• Be completely sure about what kind of fluid you will be pumping. Thispump is only intended
for pumping clean water that is not to be used as drinking water.
• Check that all nuts, screws, bolts, hose couplings and plugs are secure.
• Check thecondition of thehoses before connecting them to thepump; remember that
thesuction hose must be reinforced so that it does not implode from thesuction when
thepump is operating.
• Check that thegasket where thesuction hose is attached is undamaged and intact.
• Check that theconnections and any hose clips are tightened.
• Check that afunctioning inlet filter is fitted on thesuction hose.
• Check that theair filter is intact and clean. Adirty air filter reduces theinduction air, and
theengine loses power.
5. Operation
5.1 Safe operation
Before using thepump for thefirst time you have to read: 2. Importantsafety information and
4. Beforeuse.
For your own safety, avoid starting theengine in anon-ventilated space. Theexhaust fumes
are very dangerous to inhale, they contain poisonous carbon monoxide that may lead to
unconsciousness or death.
Only pump water that is not intended for drinking. Pumpingflammable fluids, such as petrol
or fuel oil, may lead to explosion or fire, resulting in heavy damage. Pumpingseawater, acid,
chemicals or other corrosive fluids may damage thepump.
5.2 Placement of the pump
The highest capacity and theshortest suction time at start-up will be achieved when thepump is
placed near thesurface of thewater. Donot use a longer hose than necessary.
If thetotal head is increased, thecapacity of thepump is reduced. Thetype, length and diameter
of thehose used also noticeably affects thecapacity.
The pressure head for thepump is always larger than thesuction head, so thesuction hose
should be as short as possible.
Low suction head is also very important in order to reduce thesuction time at start-up
(the time it takes before theentire pump housing and suction hose is filled with water).
5.3 Fitting the suction hose
The suction hose must be equipped with an inlet filter, and ideally with anon-return valve
(the non-return valve reduces thesuction time at up-start).
The suction hose should not be longer than necessary, theoptimal pump capacity is achieved
when thepump is placed near thesurface of thewater and thesuction hose is short.
Never use asuction hose with an inner diameter smaller than 25 mm (1″).
