SAFETY INFORMATION
Dri-Eaz is concerned about the safety of anyone who
uses 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.
•
Never
allow any materials, such as draperies, to obstruct
the air inlet or outlets. This could cause the unit to overheat
and result in a fire or electrical hazard.
•
Never
allow children to play on or around the unit. Be
sure the unit is inaccessible to children when left unattended.
Children could seriously injure themselves or others by
playing with or around the unit.
•
Never
operate or store the unit outdoors, or otherwise
expose the unit to water. The housing is not waterproof, and
water allowed inside the unit could cause an electrical shock
hazard or damage to the unit. If electrical components be-
come wet, allow the unit to dry thoroughly before operating.
•
Never
insert any implement or device into the unit when
it is operating, which could cause an electrical shock or
damage to the unit.
•
Never
operate the unit with a damaged electrical cord or
plug, which could cause a severe electrical shock or fire haz-
ard. Visually inspect the electrical cord and plug for damage
before each use.
•
Never
direct fogged chemicals or chemicals of any type
into the unit, which could cause a fire hazard or damage to
the unit.
•
Never
operate the unit in temperatures above 105
°
F
(41
°
C), which could cause damage to the desiccant rotor or
electrical components.
•
Never
allow condensate water which may collect in the
reactivation ducting during operation to run back into the
unit. This could cause a shock hazard or damage to the unit.
Keep at least part of the ducting lower than the reactivation
outlet at all times.
•
Never
operate the unit without the air filter, which could
cause damage to the desiccant rotor from contaminants.
•
Never
open the unit cover with the power connected,
which could cause an extreme electrical shock hazard. The
power source provides enough voltage and current to cause
death or severe burns. Always turn off the power before you
work inside the unit. Do not work with the electrical parts
unless you are a trained electrician.
•
Never
wash the rotor with any solvent. This could per-
manently damage the rotor.
•
Always
ensure that correct voltage is used. Failure to do
so could cause an electrical shock or fire hazard.
•
Always
secure the unit to prevent sliding when trans-
porting in a vehicle, which could cause injury to vehicle
occupants, or damage to the vehicle or unit.
PRINCIPLES OF OPERATION
DriTec Desiccant Dehumidifiers are designed to reduce
humidity by removing moisture from the air. This helps to
dry wet carpets, cushions, floors, walls, contents and struc-
tural materials. It also prevents mold and mildew growth
caused by moist or humid conditions.
Figure 1 shows how DriTec Desiccants remove moisture
from the air. The heart of the system is the rotor, which has a
series of air passages or channels. Air can be forced through
these channels in either direction.
The passages inside the rotor are coated with a special
silica gel substance which is a "desiccant," a material with a
unique affinity for water. When damp air passes through
rotor, the desiccant material "adsorbs" or captures the water
vapor, thus drying the air. The DriTec's desiccant material
employs rare metal technology to increase the attraction of
water to the silica gel.
