VK 111-610 Steamer Calibration & Fault Codes
BASIC CALIBRATION PROCEDURE:
1. Remove two (2) screws to open access panel at bottom rear of
steamer. Replace control board if defective. Reset control board
(see page 1).
2. For steamers used
below
1968
foot elevation, leave
red
wire
attached to wire loop and
remove
black
wire. For steamers used
above
1968
foot elevation, leave
black
wire attached to wire loop
and
remove
red
wire.
3. To perform basic calibration, fill steamer (to bottom mark) with
50
oz.
(
1.5 liters
)
max.
of water, then put cover on. Turn steamer
on
, then rotate knob quickly
(less than 8 seconds) fully clockwise
to
steam
setting to heat water. Steamer calibrates itself as it
heats. While water is heating,
yellow
indicator light comes on.
Basic calibration will finish after 6-7 minutes --
yellow
indicator
light will
blink slowly
when done.
4. If basic calibration has failed (see fault codes below), reset control
board (see page 1) and repeat basic calibration.
5. When basic calibration is successful, turn steamer
off
, then
remove calibration cable. Reattach access panel. Turn steamer
on
, then perform boiling point calibration (below) and test normal
operation --
yellow
indicator light should
not
be flashing. If water
is still hot,
yellow
light may not turn on for several minutes.

BOILING POINT (ELEVATION) CALIBRATION PROCEDURE (from Owner’s Manual - can be done
by customer):
1. Perform basic calibration (see instructions above). Turn steamer
off
, then remove calibration cable.
Reattach access panel.
2. Fill steamer (to bottom mark) with
50 oz.
(
1.5 liters
)
max.
of water, then put cover on. Turn
steamer
on
and rotate knob quickly
(less than 8 seconds) fully clockwise
to
steam
setting. Within
five (5) seconds of turning to
steam
setting, rotate knob twice between
200ºF
and
steam
settings,
leaving knob at
steam
setting. The
yellow
indicator light will flash until the adjustment is done.
3. When boiling point calibration is successful, steamer switches to
steam
mode (for normal
operation). Once steamer reaches
steam
mode, test normal operation --
yellow
indicator light
should
not
be flashing. If water is still hot,
yellow
light may not turn on for several minutes.
