3.0 OPERATION
Procedure for Pressure Relief
In orderto avoid the risk of seriousbodily injurysuch as spraying fluid on the skin or in the eyes,or ,..
risk of injury from moving parts, the following procedure should be used. This procedure should be used
when shutting down the pump, when servicing or repairing the pump or any part of 1he system, when
replacing or cleaning components, or when pumping of fluid is stopped.
1. Close the air valve to the pump. '
2. Use the air bleed-off valve (see installation instructions) to relieve the air pressure in the system.
3. Relieve the fluid pressure by slowly opening the drain valve. (Use a grounded metal pail in contact
with the metal part of the fluid drain valve)
4. With a container ready, catch the fluid by opening the drain valve(see installation instructions).
5. It is good practice to leave the drain valve open until it is time to dispense fluid again.
If you are unsure if the fluid pressure has been relieved (due to a blockage in a component or a hose),
carefully relieve the pressure by slowly loosening the hose end coupling to allow the fluid pressure
to escape slowly. After the pressure has been relieved, the fitting can be removed completely and any
blockages removed.
Startup andAdjustmentof the pump ~
Ensure that installation is fully completed before proceeding to start up operations.
1. Ensure that the air regulator(A)and the bleed-off master air valve(D)are closed. ~

2. Into a grounded metal container, open the dispensing valve slowly. Ensure metal-to-metal contact
between the container and the valve.
3. Open the bleed-off air valve and adjust the air regulator (A)slowly for pressure just enoughto start
the pump. This is to prime the system. After all the air has been expelled from the lines, close the
dispensing valve. Duringthe priming ofthe pump, the pump should run when the dispensing valve is
opened andstop when the valve is closed.
4. Turn the air regulator slowly until sufficient flow from the dispensing valve is achieved. Remember r
to run the pump always at the lowest possible speed necessary to achieve what is desired. Never \
exceed the maximum working pressure of any component in the system.
5. The pump should not be left to run without fluid to pump. When running empty, the pump will
accelerate and probably damage itself. During operation, should the pump be found running too
fast, stop it immediately and check the fluid supply. Is the fluid level in the drum too low or empty?
If air has gone into the system, do a priming procedure. Ensure that all air has been expelled from
the lines before operating again. Flush the pump or leave it filled with a compatible solvent
when not in use.
6. Always follow the Pressure Relief Procedure when the pump will be shut down for any extended
period of time or during system shut off at the end of the day.
Daily Maintenance Check ..,
1. Ensure sufficient lubricant in the air lubricator. J
2. Drain the moisture trapped in the air filter.
