P
eriodic checks
• After one hour of operation: Check that there are no significant
water leaks.
• Ever
y fifteen days or no more than 300 operating hours: Check
operation, that there are no significant water leaks and the
general condition of the cylinder. Check that during operation there is no arcing between the electrodes.
• Every three months or no more than 1000 operating hours: Check operation, that there are no significant water leaks and, if
necessary, replace the cylinder. Check that there are no blackened parts
of the cylinder. If there are blackened parts of the
cylinder, check the condition of the electrodes, and if necessary replace the cylinder.
• Annually or no more than
2500 operating hours: Replace the cylinder.
CAUTION: ALWAYS DISCONNECT THE MAIN POWER BEFORE DOING MAINTENANCE!
CAUTION: always disconnect the main power before touching the cylinder in the event of leaks, as current may flow through the water.
7.2 Cylinder maintenance
The life of the cylinder depends on a number of factors, including: the amount and type of mineral
s
in the water, the correct use
and sizing of the humidifier, and the output, as well as careful and
regular maintenance. Another factor affecting cylinder life is
M
aximum
P
roduction, the higher the production rate the shorter the cylinder life; for this reason
the DS-35 and RS-35
are preset
from the factory
at 7
0
%. Further reductions in maximum production will extend cylinder life. See figure 7.a
IMPORTANT WARNINGS
The humidifier and its
cylinder contain live electrical components and hot surfaces, and therefore all
service and/or maintenance operations must be performed by exper
t and qualified personnel, who are
aware of the necessary precautions. Before performing any operations on the cylinder, check that the
humidifier is disconnected from the p
ower supply. Remove the c
ylinder from the humidifier only after
having drained it completely using the manual “drain” button or procedure. Check that the model and
the power supply voltage of the new cylinder correspond to the data on the rating label.
7.2.1 Replacing the cylinder
IMPORTANT WARNING:
Th
e cylinder may be hot. Allow it to cool before touching it or use protective
gloves.
To replace the cylinder:
1. Completely drain the cylinder by pressing and holding the “drain” button until the cylinder is
empty.
2. Turn the humidifier off and disconnect the main p
ower.
3. Remove the cover.
4. DS Models.
a. Remove the steam hose from the cylinder.
b. F
l
ip up the cylinder holding bracket and lift the cylinder out of the unit.
5. RS Models
a. Undo the 2 bolts of the embedded fan.
b. F
l
ip up the cylinder holding bracket.
6. Disconnect the distributor from the cylinder and lift the cylinder out of the unit.
7. Disconnect the electrical connections from the top of the cylinder.
8. Install the new c
ylinder in the humidifier by pe
rforming the previous operations in reverse.
WARNING: Electrical connections to the c
ylinder must be tight or possible fire hazard may result.
Threaded nuts on power wires must be connected with
2.5 to 3.3 Nm
(22 to 29 inch-pounds of torque).
7.2.2 Maintenance of the other plumbing components
IMPORTANT WARNINGS:
• External power must always be disconnected when per
forming any maintenance on the humidifie
r.
• When cleaning the plastic components do not use detergents or solvents;
• Scale can be removed using a solution by using vinegar or a weak solution of acetic acid and a soft
brush; the
n
rinse the cylinder thoroughly with fresh water.
Cleaning the fill valve:
After having disconnected the cables and the hoses, remove the valve and check the condition of the
inlet filter; clean if neces
sary using the same cleaning solution as for the steam cylinder and a soft brush.
Cleaning the drain valve:
Remove the valve body, clean if necessary using the same cleaning solution as for the steam cylinder
and a soft brush.
Cleaning the drain pan:
Clean the pan of any mineral deposits and check that the wate
r fl
ows freely from the pan to the drain at
the drain valve.
Cleaning the supply, fill, overfl
ow pipes: Check that these are clear and clean or replace if necessary.
IMPORTANT WARNING:
A
fter having replaced or checked the plumbing, check that components have
been reconnected correctly with the proper seals. Re-star
t the humidifier and pe
rform a number of
cleaning cycles
(2 to 4
cleanings,
read chap. “Starting with a new cylinder”), then check for any water leaks.
