WARNING

The maximum working pressure of each pump in your system may not be the same. To reduce the risk of overpressurizing any part of your system, be sure you know the maximum working pressure rat- ing of each pump and its connected components. Never exceed the maximum working pressure of the lowest rated component connected to a particu- lar pump.

To determine the fluid output pressure using the air regulator reading, multiply the ratio of the pump by the air pressure shown on the regulator gauge. For example:

5:(1) ratio x 100 psi air = 500 psi fluid output

[5:(1) ratio x 0.7 MPa ( 7 bar) air = 3.5 MPa (35 bar) fluid output]

Limit the air to the pump so that no air line or fluid line component or accessory is over-pressurized.

1.Open the master air valve from the compressor.

2.Trigger the dispensing valve into a grounded metal waste container, making firm metal-to-metal contact between the container and valve.

3.Open the bleed-type master air valve, and open the pump air regulator slowly, just until the pump is running. When the pump is primed and all air has been pushed out of the lines, release the trigger.

NOTE: When the pump is primed, and with sufficient air supplied, the pump starts when the dispensing valve is opened and shuts off when it is closed.

4.Set the air pressure to each pump at the lowest pressure needed to get the desired results. Use the regulator to adjust pump speed and pressure.

CAUTION

Never allow the pump to run dry of the fluid being pumped. A dry pump quickly accelerates to a high speed and could possibly damage itself. If the pump accelerates quickly, stop it immediately, and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and lines with fluid, or flush it and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.

NOTE: A pump runaway valve can be installed on the air line to automatically shut off the pump if it starts to run too fast. See Air and Fluid Line Accessories on page 6.

5.Read and follow the instructions supplied with each component in your system.

6.To shut off the system, always relieve the pressure.

WARNING

INJECTION HAZARD

To reduce the risk of serious injury whenever you are instructed to relieve

pressure, always follow the Pressure Relief Procedure at left.
