Congratulations
on your selection of a new DriTec™
325 Desiccant Dehumidifier or a DriTec 150 Desiccant De-
humidifier from Dri-Eaz Products, Inc. It is our goal to offer
you the best high performance dehumidifier available. We
invite your comments and suggestions for modifications and
improvements. Reading this Owner's Manual will help you
achieve maximum benefits from your dehumidifier.
Read Manual and Safety Information.
Make sure that
all technicians and operators who use the DriTec read and
understand the owner's manual prior to operation. Pay par-
ticular attention to the safety information in order to reduce
the risk of electrical shock, fire, or personal injury.
Inspect on Arrival.
When your DriTec arrives, check
immediately for signs of shipping damage. If you do notice
any damage, report it to your supplier and the shipping com-
pany immediately. It is important to save the shipping carton
for claim purposes. If your DriTec ever needs repairs at a
remote location, the unit should be packed and shipped in its
original carton.
INTRODUCTION
The DriTec Desiccant Dehumidifier is designed to re-
duce humidity by removing moisture from the air. Proper
dehumidification helps to speed the drying of wet carpet,
cushion, floors, walls, contents and structural materials. It
also prevents mold and mildew growth caused by moist or
humid conditions.
The DriTec Desiccant can create extremely low humidity
conditions, and can operate efficiently in very low tempera-
tures. These two benefits of the desiccant dehumidifier are
not possible with refrigerant dehumidifiers.
Your DriTec Desiccant Dehumidifier is durable and sim-
ple to operate, needing very little maintenance. The DriTec
can give you years of trouble free service if you follow the
recommendations in this manual.
We strongly advise that you read and study the manual.
You will learn how your desiccant dehumidifier works and
how to get the best service from your DriTec Desiccant.
If you do not understand something in this manual or if
you have a question about your dehumidifier, call the Ser-
vice Department at Dri-Eaz Products, (360) 757-7776.
SAFETY INFORMATION
Dri-Eaz is concerned about the safety of anyone who us-
es or performs maintenance on the DriTec Desiccant unit. It
is dangerous for an untrained individual to attempt to use or
perform maintenance on the unit. Throughout this manual
we point out some of the precautions which should be taken
in use or maintenance of the.
We use three different kinds
of messages to warn you of possible problems or precau-
tionary measures:
Danger
–
Immediate hazard which will result in severe
personal injury or death.
Warning
– Hazard or unsafe practice which may result in
severe personal injury or death.
Caution
– Hazard or unsafe practice which could result in
personal injury or property damage.
Please keep these points in mind as you use or service
the unit.
Never
use the DriTec 325 or the DriTec 150 without a
proper extension cord. Do not use the 325 with any exten-
sion cord other than the one available from Dri-Eaz Prod-
ucts. Use of any other extension cord may cause an electrical
short or fire hazard.
Never
alter the grounding plug or remove it from the
electrical cord. Do not use an adapter that defeats the dehu-
midifier’s electrical grounding. This could cause an electri-
cal shock or fire hazard. Do not use the unit for any reason if
it cannot be properly grounded.
Never
operate the unit in standing water, because of the
risk of serious electrical shock hazard. The unit may be oper-
ated on damp surfaces but not in standing or pooled water.
