APPLICATION NOTE

AN 131

SUPPLEMENT TO THE

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.
