6. Empty the A material tank:
a. Close the A side mix manifold inlet ball valve.
b. Disconnect the A material hose from the mix
manifold at the fitting between the ball valve and
check valve.
c. Place the A material hose in a clean container
to salvage the dispensed material. Make sure to
have enough clean containers within reach to
switch to as each container is filled.
d. Open the A side mix manifold inlet ball valve.
e. Press repeatedly to set to
Slowly turn metering pump air regulator (CD)
clockwise to increase air pressure until metering
pump A starts. Continue pumping until the
metering pump speed increases on its own
which signals that the tank is now empty and
there is air at the metering pump inlet. Press
to stop metering pump then back out the
air pressure regulator.
f. Close the A side mix manifold inlet ball valve.
g. Close the tank air supply ball valve then open
the brass valve on the top of the tank to relieve
tank air pressure.

j. Re-install the tank lid assembly.
k. Close the brass valve on the top of the tank
then open the tank air supply ball valves to
pressurize the tank.
l. With selected, press
metering pump air regulator (CD) clockwise to
increase air pressure until metering pump A
starts. Wait until the metering pump speed
decreases, meaning that it is now primed with
the new material from the tank inlet. Continue
pumping until the metering pump speed
increases, which means all of the material has
been pumped and there is air at the metering
pump inlet. Press
then back out the air pressure regulator.
a. On the A side feed module, close both feed
system 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.
