5.5 Refilling Water
Every two weeks the machine should be refilled with tap water. Pour 0,5 liters in the blasting chamber at a time and check the
water level. To check the water level remove the filter and look for standing water in the filter housing.
Figure 6: Remove the filter and check the water level.
5.6 Emptying Water
There are two ways to empty the Density from water, one which can be used in all circumstances and one that can be used if
there is a floor drain available.
In all circumstances, the machine can be emptied by putting a bucket, 5 liters maximum, inside the blasting chamber and using
the nozzle to shoot water into the bucket. Always close the lid before shooting water in the chamber. There are approximately
20 liters of water inside the Density so you will have to empty the bucket a few times during the process. The system is empty
when no more water comes out of the nozzle even though it is activated.
WARNING: DO NOT, AT ANY TIME, WHEN THE LID IS OPEN TURN ON THE WATER AS THE HIGH-PRESSURE WATER
JET CAN CAUSE SERIOUS INJURY.
If there is a floor drain close to the Density the machine can be emptied using a hose. There is a drain valve available at the
bottom front right corner of the Density where a hose with a female Gardena coupling can be connected. Once the hose is
connected the valve can be opened and the system will empty itself. When the system is empty, close the valve and remove the
hose.
