Draining the Cleaning Fluid
NOTE:
The cleaning fluid should be changed completely at least once a year. The
filters must also be changed when this is done.
CAUTION
: When handling cleaning fluid, chemical protective gloves and eye
protection should be worn.
For draining the fluid, the machine must be put into the “maintenance
mode.” This function basically disables the fluid level sensor. Switch the
machine to maintenance mode as follows:
1.
Remove the front compartment panel by turning the two black fasteners ½ turn
counterclockwise. Tilt the panel out from the top, then lift up to remove it.
2.
Bring up the “Manual Functions” screen as described in Section
III.6
.
3.
Touch the green and red [
MODE
] switch on the screen. The switch will then
change its status from [
Normal
] to [
Maint.
] Follow the same procedure to
return from [
Maint.
] setting to [
Normal
].
CAUTION
: Running the machine in the maintenance mode creates the risk of
running the pumps dry, which might damage them. This mode should be used only
when draining the machine, and only by trained personnel.
4.
Return to the Operations Screen by pressing the
[+]
button twice.
5.
Turn off the pumps if they are running.
6.
Locate the short tube connected to the valve
V3
, and place the tube in a recovery
container of at least 15 gallon capacity. See
Fig. 8
.
7.
Open valve
V3
and turn on the pumps.
8.
Watch the level in the tanks; when they are both empty, turn off the pumps. Do
not let the pumps run dry for an extended period or damage to the unit could
result. Close valve
V3
.
9.
Remove the three filter housings, pour out the fluid and discard the cartridges
and O-rings. Clean the housings thoroughly. Note that the fluid and cartridges
could contain hazardous materials, depending on what is being cleaned.
10.
When finished, bring up the “Manual Functions” screen as described in Section
III.6
. Press the [
MODE
] button to return the machine’s [
MODE
] to [
Normal
].
