WARNING
DEATH, BURNS, OR ELECTRIC SHOCK can occur
by touching electrical components and wires inside
the access cover when the main power switch is in
the on position. Use extreme caution when
performing this procedure.
8. Turn the main power switch to the on position, check that water
supply valves are open, and turn the steamer on by pressing the
POWER switch to ON. The red switch indicator turns ON and the
generator begins to fill.
9. When the steam generator stops filling, pour 2 or 3 cups of
phosphoric add into the water in the steam generator.
10. Check that the water level is above scale buildup. Add water until
water covers all scale.
11. Energize heater
by pressing the TIMED/MANUAL switch to the
MANUAL position. Allow water to heat to 140 to 160 degrees.
12
.
When water heats to 140 to 160 degrees, turn OFF the heater by
pressing the TIMED/MANUAL switch to TIMED. Leave the
POWER switch ON. A bubbling and hissing sound indicates that
the add is dissolving the scale.
13. Leave add in the steam generator for at least 1-1/2 hours. Full
descaling may take several hours, depending upon the amount of
scale buildup. If add is consumed (bubbling and hissing stops),
add one or two more cups of add to the steam generator solution.
NOTE:
If steam generator
is too full to add more add, press the
POWER switch to OFF for a few seconds to drain some
solution. Then press POWER switch back ON.
14. After the time listed in step 13 elapses, switch the POWER switch
to OFF, thus starting the steam generator drain and blowdown.
15. Inspect the steam generator
as described in step 7. If scale is com-
pletely removed, go to step 16, otherwise repeat steps 7 through
15 until all scale is removed.
16. Refill the steam generator with cold water. Press the
TIMED/MANUAL switch to the TIMED position and press the
POWER switch to ON.
17. Add three or four tablespoons of baking soda to the water to
neutralize any remaining add.
18. Replace the cover plate or pipe plug and secure the right side
access cover with the two screws.
19. Set TIMER for 10 minutes.
20. At the end of the TIMED cycle, the buzzer sounds and the unit
stops steaming.
