been pumped and there is air at the metering
pump inlet. Press to stop metering pump
then back out the air pressure regulator.
7. Add solvent to the A material tank:
a. On the A side feed module, close both feed sys-
tem air control ball valves and back out the air
pressure regulator. Open the brass valve on the
top of the tank to fully relieve tank air pressure.
b. Remove the platen from the A side feed pump
by loosening the two setscrews and the air tube.
c. Place a pail of solvent under the feed pump
then slowly insert feed pump into the pail. The
feed pump should rest on the bottom of the pail.
d. Slide the air motor slider valve (DF) to ON.
Adjust the air regulator (DE) so the feed pump
runs very slowly.
e. Continue adding solvent to tank until enough
solvent is in the tank to expel the remaining
material from the hose bundle material line.
8. Salvage the A material from the hose bundle mate-
rial line then flush the hose bundle material line:
a. Press . Slowly turn metering pump air
regulator (CD) clockwise to increase air pres-
sure until metering pump A starts. Continue until
the material appears to be thinner, which is a
sign that the solvent is mixing with the material,
then press to stop the metering pump.
Back out the air pressure regulator.
b. Cover the material container and store for later
use.
c. Move the A material line to a waste container.
d. Press . Slowly turn metering pump air
regulator (CD) clockwise to increase air pres-
sure until metering pump A starts. Continue until
clean solvent is dispensed, then press to
stop the metering pump. Back out the air pres-
sure regulator.
e. Reconnect hose bundle material line to the mix
manifold.
f. Disengage trigger lock then trigger gun into the
waste container and press . Slowly turn
metering pump air regulator (CD) clockwise to
increase air pressure until metering pump A
starts. Continue until clean solvent is dis-
