5. When ready for this, be sure the tank valves are closed on
the empty tanks. Bleed off any pressure in the lines by pulling
the trigger of the gun while aimed into a waste container.
6. Disconnect the lines and transfer to the new set. Be sure to
have on proper protective equipment as some residual
material will be in the lines.
7. Back out the regulator valve handles (counterclockwise) and
then proceed with the calibration process as outlined above.
8. Replace the plugs and caps on the tank connections. Attach
the Bill of Lading to the empty tanks and call them in to be
picked up along with the paperwork that came with the tanks.
9. Remove the used nozzle by pushing down on the
nozzle ejector.
10. Turn off the chemical tank valves. The handles should
be perpendicular to the valves.
11. Depressurize the chemical lines by engaging the trigger,
dispensing the chemical in an appropriate container.
12. Clean any chemical on the INSTAFLO™ Gun face
with a rag.
13. Turn off the on-off valves located near the tank filter.
The valve handles should be perpendicular to the
chemical lines.
14. Turn off the yellow-coded nitrogen intake valves of
the “A” and “B” tanks. The handles should be perpen-
dicular to the valves.
15 Turn off the nitrogen cylinder by turning the valve in
a counter-clockwise direction.
16. Back out both nitrogen regulator valve stems until
they are freewheeling.
9.1 “A” Tank Change-over
1. Position the new “A” tank next to the empty “A” tank.
2. Verify that the nitrogen intake and chemical valves
of the new “A” tank are closed. The handles should be
perpendicular to the valves.
3. Remove the yellow-coded cap on the nitrogen intake
valve of the new “A” tank.
4. Relieve the nitrogen pressure by loosening and
removing the yellow/red coded nitrogen regulator line
from the nitrogen intake valve of the empty “A” tank
using an adjustable wrench.
5. Reconnect the “A” yellow/red coded nitrogen line to the
nitrogen intake valve of the new “A” tank. Tighten the
connection with an adjustable wrench.
6. Remove the chemical valve plug of the new “A” tank
and place the plug on top of the new “A” tank.
7. Carefully remove the vaseline in the “A” chemical
tank valve.
8. Remove the fluid filter from the canvas bag on top of
the new “A” tank. Verify that the filter and the cartridge are
free by shaking the filter until you hear a “clicking sound”.
NOTE: Air blown into end in the direction of arrow will pass freely through
the filter.
9. Connect the filter to the new “A” tank chemical valve with the
filter arrow pointing away from the tank. The arrow represents
the chemical flow. Tighten the filter with an adjustable wrench.
The filter prevents chemical from flowing back into the tank.
CAUTION: When disconnecting chemical lines, always cover the
connections with a rag to minimize chemical spray or spillage.
10. Disconnect the “A” on-off valve from the filter of the
empty “A” tank, covering the connection with a rag.
