6. Connect the exhaust hose to the exhaust elbow, and tighten the hose clamp
securely. Place the open end of the exhaust hose in a fume disposal mechanism.
7. Using an “M” style 1/4” quick disconnect socket hose coupling, connect a
compressed air line to the plug coupling of the airfl ow amplifi er assembly.
Maximum air pressure is 150 psi.
CAUTION
Air fl ow to the system should be on at all times during operation.
The airfl ow solenoid will automatically turn air on when the “Start”
key is pressed and microwaves are being produced. Air will be
turned off when the system is below 50 C.
NOTE
The pressure gauge is factory is set at 60 psi; however, pressure set-
ting can be affected by the compressed air source.
8. If necessary, unlock and adjust the pressure gauge (large black knob directly
above the gauge) clockwise to raise the pressure or counterclockwise to decrease
the pressure.
9. Lock the pressure gauge at 60 psi.
Note: Proceed to step 11 for continuing Phoenix AirWave startup.

10. Connect the exhaust hose to the cavity exhaust outlet by pushing the plastic
elbow as far into the exhaust outlet as possible. Orient the plastic elbow so that
the exhaust hose extends toward the fume disposal mechanism. Place the open
end of the exhaust hose in a fume hood or other fume disposal mechanism.

11. Remove the door and top of the muffl e furnace. Place the heating element into
the furnace bottom (fi gures 8 and 9).
12. Position the bottom portion of the muffl e furnace with the heating element in the
center of the instrument cavity. Place the top of the furnace on the installed
furnace bottom. Ensure that the thermocouple ports in the furnace and the top of
the instrument cavity are aligned. For AirWave, insert the metal chimney into the
large opening in the top of the furnace. Align the chimney with the instrument
exhaust outlet.
