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 InSTa-FlO™ 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 .
