5. The Rate control Dial is used for adjusting the speed of the pumps and is located
on the control panel. Turn the Rate Control Dial to zero.
6. With air pressure to the system, turn the power on/off switch to ON position. The
Red Lion LCD should light-up and read zero.
7. Set the Start / Stop switch to the Stop position.
8. Turn the Mode Select switch to the Gun position. The pump should not run but
the dispense gun valve rod should rotate to the ON position and the recirculation
gun should close. There is a machined slot in one end of the valve rod which
should be horizontal in the open position and vertical in the off position. Refer to
parts drawing CPD-6100, item 26 part number 58693-1 to verify. Turn Mode
Select switch to Recirc, the valve rod should rotate to vertical position. After
checking dispense gun open/close positions, turn Mode Select switch to the Gun
position (gun open).
9. Check that the ball valves between the material tanks and filters are open; the
ball valves on the bottom of the filters should remain closed.
10. Now set the Start / Stop switch to the Start position. Note the hydraulic pump
and motor will start.
Note: with the Ratio Block a couple of fittings and some poly tube installed on the
front of the dispense gun the two components can be returned to the tanks or
source without the risk of contamination.
11. With ratio block attached to gun head, turn the Rate control dial (clock wise) to
begin cycling the pumping system. Once a steady flow of both A & B materials,
note if any fluid pressures of both materials, if no pressure is reading, increase
pump speed. For gravity feed container systems, very little fluid pressure is
required for ratio checks but the fluid gauge needle should come off its stop even
if an exact reading is not obtainable.
12. Turn the Select switch to the Recirc position, the dispense gun valve rod should
close and the recirculation gun valve rod open returning the materials to the
source tanks. When using the ratio block, the two materials have not come into
contact and no solvent flush should be required at this time.
13. To stop the unit from Recirculating set the Start / Stop switch to the Stop position
or turn the Rate control dial to zero (all the way counter clock wise).
