5. Set the control panel as follows:
a. Press the OFF (bottom) end of the ON/OFF switch.
b. Press the TIMED (top) end of the TIMED/MANUAL switch-
c. The timer setting is not important while the ON/OFF switch is
in the OFF position.
• The key pad timer display is blank without power.
• Even if the dial timer is not zeroed (pointing to the 0 mark), the
timing circuits are not powered.
6. Remove the right side access cover (see Figure 2-16).
Death, severe electrical shock or equipment damage can result
from touching any component inside unit when main power
switch is in the on position. Use extreme caution during testing
with the access cover removed.
7. Turn on electric power to the SteamCraft 3.1 at the main power
switch. The steamer will immediately start a blowdown cycle.
During blowdown, the condenser and drain valves are fully open
while the steam generator and float assembly are flushed with fresh
water. The blowdown cycle lasts 3 minutes. During the automatic
blowdown cycle, make the following checks.
• Look at the top of the float control. There should be a steady flow
of water entering the top of the float chamber through the spray
nozzle.
• Look at the one inch vent gap between the steamer drain pipe and
the floor drain. A steady stream of water should be draining from the
steamer.
• After about 3 minutes, the cycle is complete. Check the two points
listed above; there should be no water flow at any of the points.
NOTE: If it is necessary to stop the blowdown cycle before it is
finished, do so by pressing the ON end of the ON/OFF
switch. This energizes the operating control circuits, the red
ON/OFF indicator lights, blowdown stops, and the steam
generator fills with water. When the ON/OFF switch is
turned OFF, the blowdown cycle will start again.
8. If operating tests will be performed next, leave the right side panel
off and perform step a below, otherwise perform step b.
a. Begin the operating tests appropriate to the control panel on the
SteamCraft 3.1 being tested. The key pad control panel tests start
after this procedure. The dial timer control panel tests start on
page 26.
