Humidifier Operation
Your AFX Series unit may be equipped with a
pure steam generator type humidifier as an
option.
Check all electrical connections for wires, which
may have become loose in shipping.
Components burnt due to loose connections are
NOT covered under warranty.
Check electrode plugs to ensure they are
pressed firmly onto the electrode pins.
Important: Loose connections will cause
overheating of the cylinder plugs and probable
melting of the plugs and/or cylinder.
Turn on the main disconnect in the primary
service feeding the unit and check that the unit
has power at the primary terminal block.
On the humidifier controller attached to the left
side of the humidifier assembly, push the black
switch to "AUTO/ON" so that it clicks into the
depressed position.
Water will start to enter the cylinder through its
bottom port and rise in the cylinder to a point
determined by the solid state control circuitry.
It is not unusual upon initial start-up for water to
fill the cylinder and cycle on the red change
cylinder light. The high level probe simply acts
as a safety to shut off the fill valve and prevent
overfilling. 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 mineral
concentration allows for lower electrode
coverage while maintaining the same stream
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.
NOTE: The AFX Series unit must be in the
humidification mode to fill or to manually drain.
Areas with 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. The installer should dissolve
not more than half a teaspoon of table salt in a
cup of water and add it to the cylinder by means
of the fill cup attached to the plumbing section
during a fill cycle.
Excessive amounts of salt will result in erratic
operation of the unit; however, normalization of
the unit will be obtained automatically through
the solid state control sequence.
For further information, consult the Humidifier
Operation and Maintenance Manual included
with each unit equipped with a humidifier.
