The Field Controls Steam Humidifier now comes equipped with a factory installed Z100, which acts
as a sacrificial metal. Put simply, minerals in the water will attack and cling to the Z100. The
minerals will not attack the other components inside the humidifier as long as the Z100 is present
and active.
This results in a dramatic decrease in mineral and scale build up on the critical components inside
the tank. In particular, it means less scale build up on the heating element which is subject to
damage from excessive scaling and over heating. This also means that efficiency stays high and
preventive maintenance is faster and easier.
The Z100 is positioned on the baffle plate inside the tank and is easily removed and replaced.
Remember that the Z100ʼs job is to become the target of mineral attack, so it will be heavily
covered with scale and should be replaced annually for best results.
To remove the Z100 you must have already unplugged and shutdown your steam humidifier and
allowed it to cool. The water tank has been drained, the water supply, drain lines and electrical
wiring have been disconnected and the unit has been removed from the duct.
Refer to the blow up view on Page 11. Using a phillips screwdriver, remove the two screws that
hold the baffle plate to the tank. Lift the baffle slightly back to clear the water probe and then straight
up and out of the tank. You can then see the round Z100, or rather what is left of it after a single
season. Notice the heavy scale build up on the Z100 that would have been on your element, if the
Z100 was not there. Use a rag or pliers to grasp the edges of the Z100 and simply unscrew it from
the baffle plate. Rinse off or wipe away any residual scale from the baffle plate and install a new
Z100. Leave a slight gap between the bottom of the Z100 and the baffle plate. Now re-insert the
baffle plate into the tank and secure with the two screws that were removed previously. Itʼs that
simple.
The Z100 can also benefit the older model steam humidifiers. Simply lay the Z100 down into the
baffle plate in the same location as the factory installed model. DO NOT lay the Z100 down into the
main tank. It may come in contact with the heating element and damage it. The dimensions of the
baffle plate prevent the Z100 from falling down into the tank.
