5.2 Safety Check
The unit should be tested to the current medical electrical standards for in-house testing for
each specific country (example, refer to AS/NZS 3551 for Australia and New Zealand).
CAUTION:
Permanent damage to this humidifier will result if the serial port is used as a
ground point during electrical safety testing.
NOTE: The correct ground test point location is on the heater plate front underside edge, as
shown in Figure 5.1., where the insulating anodizing layer has been removed.
