Operation
See FIG. 1 to identify references shown in parentheses, i.e., (A).
This equipment stays pressurized until pressure is manually relieved. Read PRESSURIZED EQUIP- MENT HAZARD warnings on page 2.
Maximum working pressure of all components in the system may not be the same. To reduce risk of over- pressurizing any component, be sure you know the maximum working pressure of each component. Never exceed the maximum working pressure of the lowest rated component in the system. Overpressur- izing any component can result in rupture, fire, explo- sion, property damage, and serious injury.
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:
3:1 ratio x 100 psi air = 300 psi fluid output
Limit the air pressure to the pump so that no air line or fluid line component is overpressurized.
Pressure Relief Procedure
1.Close the pump air regulator (C) and the
2.Hold a metal part of the dispensing valve (H) firmly to a grounded metal waste container, and trigger the valve to relieve fluid pressure.
Starting and Adjusting the Pump
1.With the air regulator (C) closed, open the
2.Open the dispensing valve (H) into a grounded metal waste container, making firm
3.Open the pump air regulator (C) slowly, just until the pump is running. When the pump is primed and all air has been pushed out of the lines, close the dis- pensing valve (H).
NOTE: When the pump is primed, and with sufficient air supplied, the pump starts when the dispensing valve (H) is opened, and shuts off when it is closed.
4.Adjust the air regulator (C) until you get sufficient flow from dispensing valve (H). Always run the pump at the lowest pressure necessary to get the desired results. Do not exceed the maximum work- ing pressure of any component in the system.
CAUTION
Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly causing pump damage. It may also get very hot.
5.If your pump accelerates quickly or is running too fast, 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 compat- ible solvent. Be sure to eliminate all air from the fluid lines.
6.Read and follow the instructions supplied with each component in your system.
7.If the pump will be unattended for any period of time, if there is an air supply interruption, or at the end of the work shift, shut off the system and always relieve the pressure.
