front and rear corners of the base rails inside of the front and rear base access panels/grills.
Once all the bolts are removed, slide the unit off the back of the shipping pallet, and tilt it so the
rear corner touches the ground. Then have someone move pallet out from under the case and
gently tilt the case forward until it touches the floor.

Error code E0=Temperature probe disconnected or failed.
The temperature controllers each reference one temperature probe that is mounted in the deck or
shelf depending on the control. Do not locate the probe to a different position.
Temperatures are digitally controlled via factory settings 1-9. Setting “1” provides the coolest
surface temperatures while setting “9” will provide the warmest. See table below for the
temperature of each setting.

10.2 Humidity Control And Pan Operation (When Equipped)
Rotate the knob clockwise to a higher setting to increase internal cabinet humidity and
counterclockwise to reduce the humidity level.
Different air temperatures will result in different relative humidity values for the same number
setting of the control.
Turning the control to “OFF” does not prevent the addition of humidity. This setting turns off the
water pan heater that is required to increase humidity levels past what the standard air heating
element does.
To eliminate all humidity generation, simply do not add water to the pan.
See also the cleaning section of this manual for details on how to remove hard water residue.
To start using the humidity pan first check that the drain valve is in the closed position. The valve
is located on the end of the drain hose underneath the display cabinet. If equipped with a rear
panel, this panel must be removed to access the hose and valve.
Pull out the sliding cover and add water until the pan is visibly full. The amount of time the water
will last in the pan depends on the air temperature and humidity level settings chosen. At max air
and humidity settings, the water should last roughly 4hrs prior to needing refilled. When the pan
needs to be refilled the blue indicator light on the humidity control panel will light up. Water may
be added prior to this, but it is not necessary.
