1 - INTRODUCTION
Your HC-300 dehumidier is durable, simple to operate, and needs very little mainte-
nance. The HC-300 can give you years of trouble-free service if you follow the recom-
mendations listed in this manual.
We strongly recommended that you read this whole manual. This should not take very
long. In return, you will learn how your dehumidier works, and how to get the best ser-
vice from your unit.
If you do not understand something in this manual, or you have a question about your
dehumidier, please call Munters at (978) 241-1100 or send a fax to (978) 241-1217. Ask
to speak with one of our Technical Support people.
1.1 DEHUMIDIFIER OPERATING PRINCIPLE
Figure 1-1 shows how the HC-300 removes moisture from the air. The heart of the
system is the HoneyCombe
®
wheel. The detail in Fig. 1-1 shows the structure of the
wheel. As you can see, the wheel has a series of air passages or channels. The pas-
sages inside the wheel are coated with a special substance called a “desiccant.” When
this substance contacts damp air, it soaks up moisture. When the desiccant is heated, it
releases the moisture again.
Let’s say that you want to dry the air in a storage room, using the HC-300. Damp “pro-
cess” air is pulled into the unit from the storage room. The desiccant in the Honey-
Combe
®
wheel picks up most of the moisture in the air. Once it has been “dried out,” the
process air is vented back into the storage room. At this point, the moisture has been
taken out of the process air, and “stored” in the HoneyCombe
®
wheel.
