IMPORTANT SAFETY INFORMATION Intended uses The pump is designed and constructed for incorporation in plants and machinery (spraying machines for the protective treatment of agricultural crops and garden plants). All other uses constitute misuse unless ap- proved by the manufacturer's technical service The pump must be used in a manner appropriate to its technical data (see “Technical Data”), and must not be modified or improperly used.
Control Unit GI40 & GIC40 GI40 and GIC40 Control Units: Control units are available for easy flow and pressure control of your sprayer system. These units include a manual dump valve and adjustable pressure relief valve to control pressure, a liquid-filled pressure gauge to monitor pressure, and shut-off valves to control flow.

Installation • The crankshaft may turn in either direction. • The water connection with the pump must be made using hoses of suitable diameter, in all case no less than that of the pump fittings, securing them to the fittings using good quality clamps. The intake hose must be coil-reinforced to prevent restrictions.

INSTALLATION INSTRUCTIONS General guidelines on water supply connection To operate correctly, the diaphragm pump must draw in liquids from containers at atmospheric pressure. Do not supply the pump with pressurised liquids. For continuous duty, the pump should not draw in water by gravity from containers with liquid level at heights above 3 m.

Safety recommendations for handling and lifting Before starting the operations, organise the intended working area so that the materials can be lifted and handled in safety. Unloading, loading, handling and lifting operations must be carried out by skilled, authorised, specifi cally trained staff.
Page 9
Safety recommendations for use Before start-up, the operator must perform the necessary safety checks. In the event of leaks from the pressurized pipes, stop the pump at once and fix the leak. Do not operate the pump above the limits set by the manufacturer to increase its performance. Preliminary checks If the pump has a pressure accumulator, check its level of inflation, see "Checking the inflation pressure".

Safety recommendations for maintenance Before doing any maintenance work, depressurise the water system and isolate the pump from all en- ergy sources. When the jobs are done, before restarting the pump, check that no tools, rags or other materials have been left close to moving parts or in hazardous zones.
MAINTENANCE INSTRUCTIONS Table of lubricants The pump is delivered complete with high-performance 30 weight, non-detergent oil suitable for the intended ambient conditions (see "Environmental operating limits"). Inspecting the pump mounting Check that the pump's fixing screws have not become loose. If necessary, tighten them with the driving torque stated in the installation design.

MAINTENANCE INSTRUCTIONS Checking the inflation pressure If the pump has a pressure accumulator, check its level of inflation, with the pump shutoff using an air chuck fitted with a pressure gauge. The ac cumulator is inflated by the manufacturer for use of the pump at its maximum pressure.

Pump Storage It is important to comply with the recommendations for storage in the operator's manual of the machine into which the pump is incorporated. For the pump itself, at the end of pumping operations it is essential to flush out the internal circuit by pump ing clean water.
TROUBLESHOOTING The information provided is intended to provide guidance how to deal with malfunctions which may occur during use. Some of these procedures may be carried out by skilled staff, while others have to be performed at specialised service centres since they require the use of specific equipment as well as detailed knowledge of repair opera tions.

TROUBLESHOOTING Remedy Problem Cause Oil seal on pump Replace the worn oil seal. shaft worn. Oil on pump body or base. Oil pressure inside pump too high. Restore correct oil level in tank. Pump using too much oil (oil flowing from delivery port) or oil Stop the pump at once.
