6 . Slowly open the nitrogen intake valve of each tank . The
valve handles should be parallel with the nitrogen lines .
7 . Slowly turn on the chemical valve of each tank . The valve
handles should be parallel to the chemical lines . Verify that
the filter connection of each tank is tight and that no
chemical leaks are present . DuPont Building Solutions
8 . Slowly turn on the on-off valves . The handles should be
parallel to the chemical lines . Verify that the connections of
each valve are tight and that no chemical leaks are present .
9 . Slowly turn on the in-line on-off valves . The handles should
be parallel to the chemical lines . Verify that the connections
of each valve are tight and that no chemical leaks are present .
10 . Remove the used nozzle by pushing down the nozzle ejector .
8.2 System Purging and Testing
1 . DO NOT breathe vapor or spray . Proper PPE and
ventilation are required . See product SDS and Section 2
of this manual for further information . Follow all
precautions for product .
2 . Dispense chemicals in an appropriate container . This is
to verify proper chemical flow . When using 120' lines
install the calibration nozzle to check the flows .
For 30' and 60' lines the flow can be checked with no
nozzle attached .
3 . Clean any chemical from the Insta-Flo
a rag or paper towel .
4 . If there has been a temperature change of more than
5ºF from the last time the system was used, re-calibrate
5 . Insert an unused nozzle with the key slot down . Push in
firmly until the nozzle ejector is seated over the back
rim of the nozzle .
6 . Dispense foam to verify proper chemical mixing . If
improper mixing or poor foam quality, refer to the
Troubleshooting section, Section 10 of this manual .
