1 – INTRODUCTION
Your HC-150 dehumidifier is durable, simple to operate, and needs very little mainte-
nance. The HC-150 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 dehumidifier works, and how to get the best
service from your unit.
This manual covers two models. The HC-150I is designed for operation on 208-240V
AC. The HC-150R is designed for 115V AC. The operating instructions are the same for
both models.
If you do not understand something in this manual, or you have a question about your
dehumidifier, 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-150 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.
