WARNING: THE MOTOR IS NOT EXPLOSION PROOF. Do not install the pump
where flammable vapours or gases may be present. Install it in an accessible place
for inspection.
It is good practice to avoid any pump contact with water splashes possibly causing water
seepage into the motor with high risk of internal oxidation and/or short circuit.
and/or short circuit.
- Prior to making any tube/hose connections, check that the inlet ports have no end caps;
- Do not position the pump at a height greater than
of the fluid to be transferred. Pump damage may occur if this height is exceeded as the
pump may not draw fluid. Make sure that the outlet tube is empty and without chokes;
- Avoid choking the inlet or outlet tubes so that pump efficiency is optimized. The use of an
inlet filter is mandatory especially with fluids containing impurities (filter grid gauge
0,5mm). In this case frequent cleaning and maintenance of the filter is advisable. Utilize
tubes and connection pieces that are resistant to the fluid types handled and avoid any
possible environmental dispersion.
The electrical installation of the pump must include a protection fuse which is suitably
rated as indicated on the motor label.
W A R R A N T Y
Always mount the anti vibration rubber fittings supplied with the pump kit. Their usage
ensures a consistent reduction in noise and vibration levels.
Electrical cabling size should depend on the distance between pump and battery power
supply.
Up to 4 m length: 1,5 mm
The use of undersized cabling can cause overheating of the electrical wiring and
subsequent fire hazard. There will also be a voltage drop at the motor terminals with a
consequent reduction in efficiency.
The flow rate value indicated on the motor label is obtained with a 13 mm internal tube
diameter. Tubes with inferior diameters will cause an increase in current with potential risk
of motor overheating.
