HARISON INDUSTRIAL DEHUMIDIFIER USER'S MANUAL - Model HD-Series
1. GENERAL
1.1. Introduction
Harison PS dehumidifiers provide an effective and efficient solution to humidity control, air steril-
ization and designed to work at higher ambient temperature to meet with non-airconditioned stor-
age requirement in hot and humid tropical climate. Harison HD-PS series dehumidifier are
designed for large airflow as 900, 2,500 and 4,500m3/h and high pressure fan to ensure better air
circulation.
Model HD-PS series 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, commodi-
ty storage, underground engineering and reference room, archive establishment, warehouses,
etc. For preventing instruments, meters, communication equipment, commodity, reference mate-
rials from getting damp, rusty, mildew, rot and causing damage.
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 a 42oC, relative humidity ≤90%
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

2.2. Inner component identification and working principle
Other main working components are: high efficient compressor, accumulator, magnetic flow
control valve, evaporator coil, condenser coil, capillary tube, centrifugal fan, temperature sensor,
humidity sensor and electrical wiring.
a. Main working principle
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 many times,
and refrigeration is achieved.
b. Dehumidifying cycle
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.
Then the dehumidified air is heated by the condenser and 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
When the environment temperature is lower ( 5oC - 18oC ) during running, the surface of the
evaporator will be frosted. The computer will judge and send the defrosting command automatically
as the situation. After defrosting, the dehumidifier will turn back to run normally. In the way of "
dehumidifying-defrosting-dehumidifying ", the machine can work normally in lower temperature
environment.

3. INSTALLATION
3.1. Delivery and storage
To ensure consistent quality and maximum reliability, each dehumidifier is inspected before
leaving the factory. If the dehumidifier is to be put into storage, it will be prioritized to install, the
following precautions should be observed:
□The dehumidifier must be protected from physical damage
□The dehumidifier must be stored under cover and protected from dust, frost and rain.
Inspection
Inspect the packing and shipment process to ensure that no damage has occurredduring transpor-
tation and storage. Any visible damage must be reported to nearest Harison representative.

Start on
1. Plug on, the unit gives off “di”.
2. Press“ON/OFF”, the running indicator lights on, and the humidity display window lightson to
display the previous set humidity. The initial humidity setting is 60% and 3 seconds later the
humidity display window light on to display current humidity.
3. Press humidity up or down key to adjust the humidity needed. If the humidity setting is 3% less
than current humidity, the unit runs; if the humidity setting is 3% more than current humidity, the
unit stops running.
4. When humidity setting is less than 30%, the unit dehumidify continuously, and the humidity
display window displays“CO”.
Shut off
Press “ON/OFF”when the unit is running, the unit stops running and all indicators die.
Notice:
1. When set RH is higher than current room humidity, the unit will not run.
2. When dehumidifying, the fan motor and compressor must run at least 3 minutes, once the
compressor start on. Do not restart the compressor again within 3 minutes after shutting off.
3. When working in low temperature, the unit judges the temperature system automatically to
defrost. When defrosting, the defrosting indicator lights on, the fan motor runs but compressor
shuts off automatically.
4. When pressing the memory key, the controller will record current humidity even if power off.
And the unit will run under previous mode after power supplied again.
5. The humidity display window displays the humidity from 30% to 90%.
6. Keep unplug if do not use the unit for long time.
7. Power supplies for HD-192B; HD504B have phase and phase protecting function, when out off
connecting 3-phases are not connected rightly with machine's enactment, all the buttons on
control panel are dead, moisture window shows “E5”, please exchange the phase or check
power,then operate the unit again.
9.When switch on three phases power source,zero line first,live line second or zero and live lines
together.
5. MAINTENANCE
Switch off the power source before maintenance. Pull out the plug from the socket.
Due to the accumulation of dust, the air filter should be cleaned to avoid effecting dehu-
midifying and going wrong periodically, at least once a month. If the dust is 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 ( d 40oC, add a little neutral detergent ) to wash or brush it, and then
clear again with fresh water.
