7.1

Periodic checks

•
After one hour of operation: Check that there are no significant water leaks.
•
Every 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 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
Maximum Production, the higher the production rate the shorter the cylinder life; for this reason the DS-25 and RS-25 are preset
from the factory at 70%. 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 expert 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 power supply. Remove the cylinder 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: the 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 power;
3. Remove the cover;
4. DS Models:
Remove the steam hose from the cylinder;
o
Flip up the cylinder holding bracket and lift the cylinder out of the unit;
o
Disconnect the steam hose adapter from the cylinder and lift the cylinder out of the unit. Bushing and O-ring
o
may fall out with cylinder removal. If so, re-seat a NEW O-ring and existing bushing back in the base.
5. RS Models:
Undo the 2 bolts of the embedded fan;
o
Flip up the cylinder holding bracket;
o
6. Disconnect the distributor from the cylinder and lift the cylinder out of the unit;
7. Set bushing to side. Do NOT discard bushing. Dispose of red O-Ring.
8. Disconnect the electrical connections from the top of the cylinder;
9. Ensure NEW O-ring and bushing are properly re-seated before inserting new cylinder. See figure 7.c.
10. Install the new cylinder in the humidifier by performing the previous operations in reverse
CAUTION: Do not tighten the 7/8" hose clamp so tight that it crushes the cylinder outlet
WARNING: Electrical connections to the cylinder must be tight or possible fire hazard may result.
Threaded nuts on power wires must be connected with 44 in-lbs ± 10% (5 Nm ± 10%).
7.2.2 Maintenance of the other plumbing components
•
External power must always be disconnected when performing any maintenance on the humidifier.
•
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; then 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
necessary using the same cleaning solution as for the steam cylinder and a soft brush.
Cleaning the drain pump:
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 water flows freely from the pan to the drain at the drain pump.
Cleaning the supply, fill, overflow pipes: Check that these are clear and clean or replace if necessary.
IMPORTANT WARNING: after having replaced or checked the plumbing, check that components have been reconnected correctly
with the proper seals. Re-start the humidifier and perform a number of cleaning cycles (from 2 to 4, read chap. "Starting with a new
cylinder"), then check for any water leaks.
