Maintenance
The ElectroVap ELMC is delivered with disposable cylinder(s) in standard which
can be replaced by cleanable ones, however, without any modification, according
to the choice of the user. Drain the steam cylinder using the manual drain key.
When the cylinder is fully drained switch off the unit and isolate the power. The
steam cylinder may be very hot. Allow it to cool down before removing.
Remove front panel from the humidifier to access the cylinder compartment.
Disconnect the steam hose from the top of the steam cylinder. Remove power and
high water level electrodes from top of the steam cylinder.
Lift the cylinder upwards until it is clear of the drain valve. Ensure that the gasket
remains in the drain valves. The disposable cylinder will be merely replaced by
new ones.
Cleanable cylinder:
Mark the edge of the cylinder halves so the can be matched up when
reassembled.
Note:
The constant heating and cooling of the cylinder may cause distortion.
Consequently the cylinder halves must be assembled in the same relative position.
Remove nuts and bolts around the centre of the cylinder. Open up cylinder. It is
important that the strainer in the bottom half of the cylinder is also cleaned.
Clean the electrodes by scraping off the mineral deposits. Alternatively, this can be
done using weak descaling solution. Rinse the electrodes and the body of the
cylinder. IT IS IMPORTANT TO AVOID DISTORTION THE CYLINDER IN
ATTEMPTING TO REMOVE ANY MINERAL DEPOSITS FROM IT. Relocate the
strainer in the cylinder base. Replace the cylinder gasket on the rim of the bottom
half of the cylinder and then locate the upper half of the cylinder on the gasket,
TAKING CARE THAT THE MARKS ARE ALIGNED. Refit the nuts and bolts.
Clean the O-ring on the drain valve and if necessary, change it. (every 2-3 cylinder
cleanings). Locate the steam outlet of the cylinder in the retaining clip.Position the
base of the cylinder over the drain valve and push downwards. Reconnect the
power cables.
General:
The humidifier requires regular maintenance to ensure efficient operation and to
prevent breakdown.
The exact maintenance frequency is variable and will depend on water quality,
hours run and level of demand for humidification.
New installations should be inspected / serviced every 2 to 4 weeks. This may be
too frequent, but it will enable a suitable maintenance routine to be established.
Routine inspection:
The following is a guide to work that should be undertaken in a routine inspection.
1 - Inspect water and steam installation for leaks and damage.
2 - Inspect electrical installation for any loose cables and or damages.
Components.
3 - Inspect the steam cylinder for scale deposits. If the scale in the cylinder is
half way up the stainer in the lower half of the cylinder it should be
replaced / cleaned (see changing steam cylinder).
4 - Inspect the inlet valve. The drain valve may become blocked with scale
from the steam cylinder. This will cause water to continually run to drain.
