Check the low-pressure water pressure gauges
The prefilter water-pressure gauge shows the water pressure before the water goes through the
filter. The postfilter water-pressure gauge shows the water pressure after the water goes through
the filter.
The usual range is2.8bar to7.6bar (280kPa to760kPa/40psi to110psi).
Do this task when the pump is operating.
Subtract the value shown on the postfilter water pressure from the value shown on the prefilter
water pressure.
If the difference between the values is more than0.7bar(70kPa/10psi), replace the water filter.
Make sure that the emergency stop operates correctly
Do this task when the pump is operating.
On the operation panel, push the EMERGENCY STOP button. Refer to Emergency stop on
page 51.
Replace the water filter:
• every 1,000 hours.
• if the difference between the values is more than0.7bar(70kPa/10psi).
Refer to Replace the water filter on page 80.
