OPERATION
NP-DK50 DI-15_08-2020 19
Alarm states indicate a potential failure of the device. Therefore, it is not
possible to deactivate the alarm signals.
All alarm signals are non-latching
– after the triggering event no longer exists
the alarm signals stop.
Operator’s position. No specific operator’s position is required. However, the
operator should remain in the range of visual or audible alarm signal, which
may depend on the actual operating conditions.
Low pressure. The signal is active when the equipment is started up until
the compressor reaches the low pressure limit. The signal may be activated
during operations due to a lack of seal in the compressed air section past the
compressor, increased air consumption or an equipment fault. The visual
indication flashes and the buzzer signal is activated.
Call on an authorized maintenance service provider in the event of a fault.
High pressure. In the case of pressure rise above the high pressure limit
indication flashes and the buzzer signal is activated. The air pump will be
turned off until the pressure drops.
High temperature . If the temperature rise above 65
°C indication flashes
and the buzzer signal is activated. Check if the cooling of compressor is not
restricted or ambient temperature is not too high.
Loss of power. In the case of loss of power symbol flashes and the buzzer
signal is activated. Check the electricity supply. After 5 minutes, the signal is
turned off.
Operators must quickly secure a backup air source for the patient in the
event any of these signals activate during equipment operation.
Test of the alarm system functionality is performed automatically when
the equipment is switched on by a short testing activation of the visual
and auditory alarm signals (light up of LED indicator and auditory
pulse).
Cleaning and replacing the air inlet filter
At least once a week take out and clean the inlet filter (5) located on the back
side. Wash the filter in warm soapy water, rinse thoroughly and allow it to
dry. Insert the clean filters so that the intake openings are completely
covered by the filters.
Cleaning the compressor
To clean the compressor, use a detergent that contains no abrasives,
chemical solvents or other corrosive agents.
