Periodical checking
Periodical checking should be carried out
monthly
and include the follow-
ing steps:
Item
Work to be carried out
Nozzle system
–
Check the spray pattern of the spray nozzles
(spray cone: optimum 90°, 60° acceptable). If necessary, clean
the spray nozzles (see
total hygiene service
).
–
Check hoses and connections for sealing
, if necessary, replace defective components.
Post evaporation unit
–
Check ceramic plates for breakage
. Damaged plates should be replaced (see full servicing guide).
Note: A grey discoloration of the ceramic plates is normal. This is due to deposits from the silver ionization.
Central unit
– Silver ionization
– Connection box
– Booster pump
–
Silver ionization
: see detailed information in chapter 6.4.
–
Check the hoses and connections
on the booster pump, the silver ionization and the connection box
for seal-
ing
. Replace defective components where necessary.
Humidifier housing/
Water container
–
Check the water container and humidifier housing for soiling
(Rust, slime, dust), clean if necessary (see
full servicing guide).
–
Check the water container behind the post evaporation unit for collection of residual water
. If residual
water is present,
check the water drain and the post evaporation unit
.
Maintenance record
– Read off the
operating parameters
, including “
Fault history
”, on the display level and enter the values on the
maintenance record sheet
.
Total hygiene service
The frequency of the implementation of a total hygiene service depends
on the operating conditions. The state of the humidifier‘s hygiene and its
components mostly depends on the quality of the humidifier water, the per
-
formance (and the frequency of replacement) of the filter installed before
the unit, the air velocity, the air temperature, and the microbiological and
chemical composition of the inlet air.
The basic rule is: when the “Maintenance due” message appears, or
at least once a year, the implementation of a total hygiene service is
obligatory.
Resetting the “Maintenance due” message
Upon completion of the total hygiene service the
“Maintenance due“
message
may be
reset
as follows: Make sure the control unit is switched
off, then
press and hold any key while switching the control unit on
.
Keep the key depressed (approx. 5 seconds) until the
red error LED
lights
up briefly (approx. 1 second).
Item
Work to be carried out
Nozzle system
–
Switch on the individual spray circuits manually and check the spray pattern of the spray nozzles
(spray
cone: Optimum 90°, 60° permissible). Remove spray nozzles with a poor spray pattern (see Chapter 6.3.2) and
clean them in an ultrasonic bath.
–
Check hoses and connections for sealing
, if necessary, replace defective components.
–
Check spray nozzles for secure seating
. Slightly tighten loose jets with open-end spanner (
width 16 mm
)
