The red light simply acts as a safety to shut off the
fill valve and prevent over-filling. With the red light on,
the water in the cylinder will continue to heat and, after
a few minutes, start to boil. After the boiling action of
the water has lowered the water level below the
sensor at the top of the cylinder, the red light will go
out and the fill solenoid will again open until the
cylinder is again full.
This cycling of the red light and fill valve will
continue until the unit’s full output capacity is reached
after which the water level will automatically lower
itself in the cylinder. (The increased concentration
allows for lower electrode coverage while maintaining
the same output.) When a stabilized condition is
reached the water will be boiling close to the cylinder
seam level. The solid state circuitry will maintain the
proper concentration in the cylinder by introducing
short drains only when necessary.
If the cylinder is manually drained the above
process will repeat itself.
Low Water Conductivity
Should normalization of the unit be required
immediately after start-up, the installer may speed up
the process by artificially increasing water conductivity.
During a fillcycle, the installer should dissolve half a
teaspoon of table salt (no more) in a cup of water and
add it to the cylinder by means of the fill cup attached
to the plumbing section.
Open the plumbing compartment and add salt
solution through cylinder outlet. Excessive amounts of
salt will result in erratic operation of the unit; however,
normalization of the unit will occur automatically
through the solid-state control sequence.
CAPACITY ADJUSTMENT
The MES Series of humidifiers come with
adjustable capacity (AC) PC boards. These boards
have a pot to adjust the output from 20 to 100%. See
Figures # 3 and 4.
CYLINDER REPLACEMENT
After an extended period of operation, in
accordance with life expectancy information, the
cylinder is completely used as indicated by the red
high water sensor light illuminated on the cabinet.
When this condition is reached, a new replacement
cylinder is to be installed.
NOTE:
Red light may come on during initial
start-up but does not mean cylinder replacement. See
Start Up and Operation section of this manual.
Consult factory or agent for replacement. Quote
the cylinder model from the white 3-digit label on the
cylinder or quote model, voltage, and serial number
from unit specification label.
WHEN TO REPLACE THE STEAM CYLINDER
The steam cylinder is disposable and must be
replaced at the end of cylinder life. Cylinder life is
