Pressure Relief Procedure

WARNING! PRESSURIZED EQUIPMENT IS HAZARDOUS! Your Tuthill pump and the system it is installed in remain pressurized
until the pressure is relieved manually. This creates the risk of serious injury from pressurized fluid, accidental spray, or splashing fluid if proper
precautions are not followed when opening or operating the system. To minimize the risk, the following procedure should be followed any time you need
to:
● Relieve pressure
● Stop Pumping
● Clean, service, or check any part of the system or pump
● Install or clean fluid spray nozzles
To safely relieve the pressure, it is paramount that you:
● Shut off the air supply to the pump
● Open the dispensing valve (if so equipped)
● Open the fluid drain to relieve all the fluid pressure in the system (place a container at the fluid drain to catch all discharged fluids; use caution as
some pressure in the system may force fluid out of the drain rapidly).
Prepping for First Use and Initial Start Up
Your Tuthill pump is tested using water during production at the factory. The pump is drained at the end of the test, but residual water may still exist
internally so it is important to flush your pump thoroughly with a compatible liquid prior to first use.
Review all "WARNING" and "CAUTION" information on page 2 prior to start up to be certain the pump is ready for operation. Re-torque all fasteners
and rings prior to start up to ensure good fluid seal. Proper torque is paramount to proper sealing; DO NOT over torque fasteners and rings (torque
specifications are located on page 8). Be sure the system and pump are grounded as necessary (G). Be sure the pump is mounted securely to a solid
surface, and the system is plumbed to absorb shock and vibration (see mounting information on pages 3, 4, & 6).
Your Tuthill AODD pump comes with open fluid ports on both ends of the suction and discharge manifolds. Orient preferred suction and discharge line
locations and install. Assemble provided plugs to seal off the fluid ports that were not used.
● Place the suction hose (F) (if used) into the fluid
container (NOTE: If the inlet fluid pressure is
greater than 25% of the outlet working pressure,
the ball check valves will not close fast enough and
the pump will not work efficiently).
● Place the end of the fluid outlet line (B) in an
appropriate container (C) to catch the dispensed
fluid. Close the fluid drain valve (A).
● With the Air Regulator (D) completely closed, open
all bleed type master air valves (E).
● If the system uses a fluid dispensing device (B),
hold it open as you slowly open the Air Regulator
(D) until the pump begins to cycle. You should cycle
the pump slowly until all the air is purged from the
fluid lines. The pump is now primed and ready for
use.
● NOTE: If you are flushing the pump, be sure to
run the pump long enough to completely flush the
pump, lines, hoses, and dispenser.
WARNING! PROPER PUMP SHUTDOWN! Diaphragm and seal life may be reduced if air pressure is applied to the pump motor
during long periods when the pump is not being used. Installing a 3-way solenoid valve that automatically relieves pressure on the air motor when a
metering cycle is complete prevents this from occurring.
