SAFETY SYSTEMS Several safety systems have been conceived during the diaphragm pump design and manufacture to safeguard the operator, in compliance with pr EN 12621 Directive about paint. SAFETY VALVE A 7 bar calibrated safety valve is installed to ensure the pump working pressure does not exceed the limits inside the feeding circuit.
The Company ANEST IWATA is not to be held responsible for any accident due to the pump use by an UNAUTHORIZED and non qualified staff using it for purposes that are different from the above mentioned ones.
5. PUMP OPERATION OPERATION DESCRIPTION Based on a simple manufacture, the operation consists in two diaphragm movement, which are both fixed at the end of a rod, pressurizing and sending the paint. The compressed air enters the air chamber from side A in picture 1. The diaphragm is moved to the left, by pushing the paint.
6. INSTALLATION AND STARTING CONDITIONS FOR INSTALLATION The installer must know the ATEX classification of the installation area, as well as the risks coming from a potentially explosive atmosphere, by paying attention to the explosion and fire risks so as to adopt the most suitable protections.
INSTALLATION OF DPS_MODELS A - STAND TYPE / CART TYPE COMMON 1. Remove the dust proof caps (B,E,F,H,I on page 21) 1. Connect the drain hose 2. Detach the pump assembly from the support by removing Hex. Bolts (M8) to the two-way valve for 3.

D - WALL MOUNTING TYPE 1. Remove the dust proof caps (B,E,F,H,I on page 21) 2. Detach the pump assembly from bracket by removing hex. Bolts (M8) 3. Flip the bracket and assemble the pump to the right position on bracket by using hex. Bolts (M8). 4.
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.
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. STARTING Before beginning working, start the pump by following the instructions below: 1. Connect ground wire set to ground. 2.

PRESSURE RELEASE PROCESS WARNING 1. Close the air to the gun. 2. Close the air to the pump (exhaust ball valve). 3. Make sure the recirculation pipe is not clogged. Then open gradually the recirculation two-way valve and leave it open. 4.
8. MAINTENANCE AND INSPECTION GENERAL NOTES A suitable maintenance is important for a longer duration of the equipment in good working condi- tions and efficiency ensuring functional safety as time goes by. All maintenance operations must be carried out by a qualified staff. The pump design and the mate- rials used to manufacture it limit the maintenance interventions to a simple periodic cleaning.
