Harison dehumidifiers provide an effective and efficient solution to humidity control.
Harison HD-series dehumidifier are designed for large airflow of 900 and 1800m3/h.
EG
AB
WW
Model HD-series computer-control dehumidifier, meticulously designed by our company,
is the most advanced one in the range. They are used to remove water content from the air
and decrease the humidity automatically. They have elegant appearance, compact structure
and complete functions. They are widely used in scientific research, industry,
communication, medical health centers, commodity storage, underground engineering and
reference room, archive establishment, warehouses, etc. For preventing instruments, meters,
communication equipment, commodity, reference materials from getting damp, rusty,
mildew, rot and causing damage.
W.

The equipment has a computer-control, it is sensitive to the relative humidity, can controls
the humidity accurately. User can select as the requirement to the relative humidity by
which the power consumption is minimised. Besides, it can defrost automatically thus can
be used normally in low temperature environment, and can be operated easily.
Suitable environment-temperature : 5oC ∼ 32oC, relative humidity ≤ 90%
WW
1.2 Warranty
The warranty period is 12 months from the date of equipment commissioning.
The warranty is limited to free replacement and shipping of any faulty part, or subassembly which has failed due to poor quality or manufacturing errors. All claims must be
supported by evidence that the failure has occurred within the warranty period, and that the
unit has been operated within the designed parameters specified.
All warranty claims must specify the unit/type number and the serial number. These details
are printed on the unit identification plate.

temperature sensor, humidity sensor and electrical wiring.
WW
a. Main working principle
W.
M
When dehumidifier is switched on, the compressor starts to work. The compressor draws in
low-pressure and low-temperature refrigerant stream from evaporator, and compresses it
into high-temperature and high-pressure gas. The gas enters into condenser and is
condensed into liquid, giving out heat. Then through capillary, the liquid is throttled into
the evaporator, absorbs heat from the air and is evaporated into gas. The gas is drawn into
the compressor through air intake pipe. Just in this way the refrigeration cycle is completed.
Such a cycle repeats time and again, and refrigeration is achieved.
b. Dehumidifying cycle
WW
The centrifugal fan makes wet air entering into the evaporator through air filter, then the air
is cooled down. When the surface temperature of the evaporator is lower than the dew-point
temperature of the air, the water content in the air is condensed and drained from the
machine. The dehumidified air is then heated by the condenser and is discharged into the
room by the centrifugal fan. Thus, the air goes through the cycle and the water in the air
gets condensed so as to achieve dehumidification.
c. Defrosting cycle
hen the environment temperature is lower ( 5oC - 18oC ) during running, the surface of the
evaporator will be frosted due to lower temperature. The computer will judge and send the
defrosting command automatically as the situation. After defrosting, the dehumidifier will

Inspection
Remove the shipment packing and inspect unit to ensure that no damage has occurred
during transportation and storage. Any visible damage must be reported to nearest Harison
representative.
3.3. Power source
EG
AB
( 1 ) The unit should be installed stably. There should be one meter of space in front of the
inflow and outflow. There should be no large obstacle around it.
( 2 ) The machine set should be far from heat source and inflammable gas.
( 3 ) The condensed water could be drained out of the room or into a pail.
( 4 ) It is advisable to not to install it in a place of heavy dust or serious pollution.
WW
( 1 ) The power should be supplied with a special wire.
( 2 ) Provide automatic air-break switch.
( 3 ) There should be reliable electrical grounding.
W.
M
3.4. Installing
( 1 ) Skilled professional personnel should perform maintenance of the unit.
( 2 ) Parking inclination of the unit should not exceed 10o.
4. OPERATION
WW
Switch on the power source
After the power source is switched on, the "POWER" light ( red ) is on; the unit is in the
standby mode.
"MANUAL" operation :
Press "MANUAL" switch, the delay light ( red ) is on. After 3 minutes, the run light (green
) is on, the compressor and the fan begin to work, and the unit is in the state of
dehumidifying. Press "MANUAL" switch again, the run light is off, the unit stops working,
the unit is in the standby mode.

" UP " or " LOWER " to select the suitable humidity as your requirement. When the
environment humidity exceeds the upper limit, the computer will judge automatically and
send the command of dehumidifying; when the environment humidity falls to the lower
limit, the computer will check automatically and send the command of stopping. In this
way of cycle, the environment humidity will be under the scope of humidity control.
Compressor can be protected automatically
WW
When discontinuous starting or switching on of the power is not more than 3 minutes, and
the " DELAY " light is on, then the compressor can not work in 3 minutes. When the "
DELAY " light is off after 3 minutes, the compressor can work again.
The unit can defrost automatically
When defrosting, the " DEFROST " LIGHT (orange ) is on.

more in the environment, it should be cleaned every week, even every day.
Clean the air filter
When cleaning, gently tap the air filter or remove the dust with a vacuum cleaner, or you
can put the air filter in warm water ( ≤ 40oC, add a little neutral detergent ) to wash it or to
brush it, and then wash with clear water.
