Check all the connection fittings of the components (pump. flexble hose, etc.) before using the equipment.

Avoid pump iding because it could damage the pneumatic system and the membranes.

SETTING-UPINSTALLATION• Fix the pump on a base by using the supporting brackets

holes.

NEVER INSTALL the pump upside-down or inclined

CONNECTION TO THE REED AIR• For pump feed use a hose with a internal diameter no lower

than 6 mm.

SUCTION AND DELIVERY HOSES CONNECTION• Connect the suction and delivery hoses to the pump it is

suggested to tighten the fillings.

• Make sure the hoses are not too heavy for the pump structure

WASHING OF THE BRAND NEW EQUIPMENT• The LARIUS 2 pump has been tested at our plant with light

mineral oil left inside of the pumping elementi ad protection. Before sucking the product, carry out a washing using a diluent.

• The suction hose diameter must be proper to the viscosity of the fluid to be pumped. The installation of a filer at the end of the suction hose is recommended.

WORKING

• Dip the suction hose into the tank of the product.

• Let compressed air flow to the pump. Adjust air pressure to the minimum level necessary to the working of the pump continually

• The pump will start and sto when all the product chamber will be full. Each time the delivery valve is open, the pump will start again to work.

The high speed of travel of the product in the hose can create static electricity through discharges and sparks. It is suggested to earth the equipment. The pump is earthed through the earth cable of the supply. The gun is earthed through the high pressure flexible hose. All the conductors near the work area must be earthed.

Avoid approaching too much to the pump piston rod when the pump is working or under pressure. A sudden movement of the piston rod can cause wounds or finger squashing.

Never spray over flammable products or solvents in closed places.

Never use the tooling in presence of potentially explosive gas.

Always check that the product is compatible with the materials composing the equipment (pump, spray gun, flexible hose and accessories) with which it can come into contact. Never use paints or solvents containing Halogen Hydrocarbons (as the Methylene Chloride). If these products come into contact with aluminium parts can provoke dangerous chemical reactions with risk of corrosion and explosion.

If the product to be used is toxic, avoid inhalation and contact by using protection gloves, goggles and proper face shields.

Take proper safety measures for the protection of hearing in case of work near the plant.

• (IF PROVIDED) TIGHTEN AND CHECK ALL THE FITTINGS FOR CONNECTION BETWEEN PUMP, FLEXIBLE HOSE AND SPRAY GUN BEFORE USING THE EQUIPMENT.

• ALWAYS USE THE FLExIBLE HOSE SUPPLIED WITH STAN-DARD KIT.

• THE USE OF ANY ACCESSORIES OR TOOLING OTHER THAN THOSE RECOMMENDED IN THIS MANUAL, MAY CAUSE DAMAGE OR INJURE THE OPERATOR.

• THE FLUID CONTAINED IN THE FLExIBLE HOSE CAN BE VERY DANGEROUS. HANDLE THE FLEXIBLE HOSE CAREFULLY. DO NOT PULL THE FLEXIBLE HOSE TO MOVE THE EQUIPMENT. NEVER USE A DAMAGED OR A REPAIRED FLEXIBLE HOSE.
