15. Maintenance
The high-pressure nozzle system is mainte-
nance-friendly. However, operational faults
which can be traced back to inadequate or
improper maintenance may occur.
Regular maintenance of the high-pressure
nozzle system is indispensable for ensuring
long service life
Risk of electrical Shock!
Hazardous electrical voltage!
Unit must be switched off and protected
against restart by expert staff (electricians or
expert personnel with equivalent training)
before any maintenance work is commenced.
15.1 Maintenance activities
For the system to operate without any prob-
lems the following checks and maintenance
tasks must be carried out regularly:
1 x per month:
»
Check water tray and housing for
contamination and clean if neces-
sary.
»
Carry out a visual inspection of aero-
sol separators and clean if neces-
sary.
»
Check the high-pressure pump oil
level.
»
Check the water filter cartridge
upstream of the pump group for con-
tamination and replace if neces-
sary; flush the mains water system if
necessary.
»
Check the resulting spray cone of
the nozzles and clean nozzles if
necessary (also see section „Clean-
ing the high-pressure nozzles“).
1 x per year (or after 2500 h):
»
Check the nozzles as part of annual
maintenance and clean in an ultra-
sonic bath (also see section „Clean-
ing the high-pressure nozzles“).
Replace nozzles, if required.
»
Change the high-pressure pump oil.
»
Change sealings and valves of the
high-pressure pump.
»
Replace water filter cartridge
»
Carry out a visual inspection of the
the spray system, the aerosol sep-
arators and the humidification cham-
ber; clean if necessary.
»
Check the function of the switch-off
devices.
After a shutdown period of more than three
months, maintenance with cleaning of the
spraying system as well as an oil and O-ring
change at the high pressure pump to be
done.
With the pumps used, the seals wear
(depending on the degree of utilisation).
Leakages occurring can be repaired by
replacing the seals. In such a case, contact
HygroMatik.
15.1.1 Changing the oil in the high-
pressure pump
An oil change on the high-pressure pump
must be carried out once a year (or every
2500 operating hours). If contamination is
visible through the oil sight glass the oil may
have to be changed more frequently.
