Operation
Pressure Relief Procedure
WARNING
The system pressure must be manually relieved to prevent the system from starting or spraying acci- dentally. To reduce the risk of an injury from acci- dental spray from the gun, splashing fluid, or moving parts, always follow the Pressure Relief Procedure whenever you
Dare instructed to relieve the pressure
DStop spraying
DCheck or service any of the system equipment
Dinstall or clean the spray nozzle.
1.* Engage the spray gun or dispensing valve safety latch.
2.Shut off the air supply.
3.* Disengage the gun or dispensing valve safety latch.
4.* Hold a metal part of the gun or valve firmly to a grounded metal waste container and trigger it to relieve the fluid pressure.
5.* Engage the safety latch again.
6.Open the pump drain valve (required in system), and have a container ready to catch the drainage.
7.Leave the drain valve open until you are ready to spray again.
*Applies only when using a spray gun or dispensing valve.
If you suspect that the spray tip, nozzle, or hose is clogged or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen completely, then clear the tip, nozzle, or hose obstruction.
Flush the Pump Before First Use
WARNING
To reduce the risk of fluid injection injury, static sparking and splashing, read and follow Flushing Safety under FIRE OR EXPLOSION HAZARD on page 5.
The pump was tested with lightweight oil, which is left in to protect the pump parts. If this solution could con- taminate the fluid you are pumping, flush it thoroughly with a compatible solvent. To start the pump, follow the procedure in Start and Adjust the Pump, below.
Start and Adjust the Pump
NOTE: Check all fittings to be sure they are tight. Be sure to use a thread sealant compatible with the fluid being pumped on all male pipe threads.
1.Place the suction hose (S) in the fluid to be pumped. See Fig. 5.
2.Close the fluid drain valve (E).
3.With the air regulator (D) closed, open both bleed- type master air valves (C).
4.Open the fluid control device while continuing with the following steps.
5.Slowly open the air regulator (D). Adjust it until the pump runs smoothly.
6.Allow the pump to cycle slowly until all air is pushed out of the lines (the fluid will be flowing in a steady stream from the fluid outlet) and the pump is primed.
WARNING
To reduce the risk of component rupture, which could cause serious bodily injury, never exceed 100 psi (0.7 MPa, 7 bar) air supply pressure to the pump. Read the warning section EQUIPMENT MISUSE HAZARD on page 4.
