8. USE
This section describes the diaphragm pump use in compliance with the safety standards in force.
Read this section carefully.
8.1 SAFETY RULES DURING USE
• TO USE the diaphragm pump COMPLY WITH the safety precautions and rules described below.
• The manufacturing company declines all responsibility if the operator does not comply with them.
It is not to be held responsible for any carelessness during the pump use, either.
• If the system is used improperly, it could be broken by causing serious damage.
• Do not change the system; use only ANEST IWATA original spare parts.
• Check the system daily: repair or replace immediately all worn or damaged parts.
• Never exceed the maximum working pressure: 7 bar (100 psi)
• IT IS FORBIDDEN to use the equipment for purposes that are different from the ones it is destined to which are described
in the use and maintenance manual. If in doubt, apply to your ANEST IWATA reseller.
• Use paints and solvents compatible with the system parts they come in touch with.
• Refer to the paint and solvent features mentioned by the manufacturer.
• Wear the protective clothes described in section 8.2.
• Comply with all the local standards on electric safety and fire risks.
8.2 SAFETY CLOTHES
Wear some protective gloves and goggles, an oxygen mask
and some ear protections during working.
In any case, follow the references of the current regulations.
8.3 PREWASH
1. Make sure the pump is installed correctly (see section 7.4).
2. Soak the suction tube into the washing liquid, or fill the hopper or the tank according to the model used.
3. Put the ball valve in the right position.
4. Adjust the inlet pressure between 2.0 and 7.0 bar.
5. Open gradually the two-way valve for paint recirculation (B on page 15). The washing liquid will have to circulate through
the dip tube recirculation pipe.
- If the Tank mount model is used, the washing liquid will circulate through the reciculation pipe.
- In the Hopper model, recirculation pipe is directly connected to the hopper.
6. Close the two-way valve for paint recirculation and adjust the paint pressure by means of paint pressure regulator
(Recommended pressure for washing 3.0 bar)
7. Press the gun trigger (or supply the automatic gun opening control with some air), without spraying air and let the
washing fluid circulate for some minutes.
8. Make sure the washing has been done and then discharge the pump residual liquid and stop it.
WARNING
THE PUMP MUST BE WASHED BEFORE USING IT FOR THE FIRST TIME, IF IT IS NOT USED FOR A LONG TIME AND
AFTER ANY COLOUR CHANGE.
8.4 STARTING
BEFORE BEGINNING WORKING, START THE PUMP BY FOLLOWING THE INSTRUCTIONS BELOW:
1. Connect ground wire set to ground.
2. For all models with suction pipe, dip it into the product tank to be pumped.
For the model with hopper, fill it with the product to be pumped.
For the model on tank, fill the product tank to be pumped.

3. Open the two-way valve for paint recirculation (Ref. B on page 15).
4. Lift and turn gradually the pressure reducer knob (Ref. C on page 15). Adjust it at a pressure slightly higher than 2.0 bar,
to enable the pump to release the air.
5. Close the two-way valve for paint recirculation (Ref. B on page 15) and release the air through the gun, too.
6. Increase the pressure of the reducer connected to the pump (Recommended pressure about 5.0 bar).
7. Adjust the paint pressure regulator as required (from 0 to 3.0 bar).
8. Adjust the spraying air by means of the reducer (Ref. D on page 15) and test the gun on a panel before using it.
PRECAUTIONS
a) Use the gun under pressure.
b) When the paint level inside the tank decreases, the pump can suck some air. Increase the paint level.
c) Do not drag the pump by pulling it by the pipes.
PRECAUTIONS: EMERGENCY STOP
WHEN THE PUMP MUST BE STOPPED BECAUSE OF THE FOLLOWING REASONS:
a) The material does not stop coming out from the gun.
b) Fluid discharge through the connectors or the damaged pipe.
CLOSE THE EXHAUST BALL VALVE
8.5 DAILY INTERRUPTIONS
1. WHEN THE PUMP IS STOPPED:
- The air supply must not be disconnected if the interruption is short.
- If the interruption is long, turn the exhaust ball valve (A) discharge the air from the circuit and open the recirculation valve
(B), to release the residual fluid pressure.
2. WHEN THE PUMP IS STOPPED AT THE END OF THE WORKING DAY:
- Wash the fluid passages.
- Remove the dip tube filter and clean it.

8.6 WRONG AND DANGEROUS USES
A WRONG EARTHING, AN INSUFFICIENT VENTILATION, A NAKED FLAME OR A SPARK CAN
CAUSE A FIRE OR AN EXPLOSION AND PROVOKE SOME SERIOUS INJURIES.
