19. Install the ratio block onto the gun head to keep the two materials separate for priming and
avoid material waste.
20. Set both pumps for the longest pump stroke for priming.
Note
If either tank or pump completely runs out of material, never re-prime fluid
section with static mixer attached. This could result in material crossover
inside the gun.
21. Pour throat seal oil (TSL-ISO) into the packing nut reservoirs
until they are ¾ full to protect the piston rods from material
drying on them.
22. Fill both containers with materials, but do not exceed 12 gallons
in either container.
Note
Any time the air driven mixer is to be used, no less
than 3 gallons of resin should be in the container.
Mixer speed should be run at the lowest speed
possible to avoid whipping air into the resin.
23. Connect the red air hose quick disconnect to the mixer air
motor.
24. Slowly turn mixer air regulator knob until desired mixer speed is achieved.
Note
Always keep the ISO tank lid on the tank and slightly snug to avoid moisture
contamination or crystals forming. Crystallized ISO will plug the fluid filter and
affect metering.
25. Turn the rate control dial on the control panel to zero.
26. With air pressure to the system, turn the power switch on the control panel to the
ON
position.
27. Turn the Start/Stop Control to the
STOP
position.
28. Turn the Mode Selector switch to the GUN position.
Note
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.
29. Turn the Mode Selector switch to
RECIRC
(the valve should rotate to
the vertical position).
30. After checking the dispense gun open/close positions, turn the
Mode Selector switch to the
GUN
position (gun open).
31. 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.
