Changing HASKRIS Tank
Regularly check Check the filter in the HASKRIS tank and record the flow rate every expedition.

The filter can be sprayed off in a sink taking care not to puncture the screening. If the water flow rate to the system begins to drop close to 4 L/minute it may mean drops to <4.5 L/min, the D4 will alarm. If it drops below 4.0 L/min, the X-ray will shut off.
