1. SAFETY WARNINGS
• The FDK100 Series Dehumidifier must always be connected using the grounded electrical
connection as required from all electrical appliances. The warranty is voided and all
responsibility for the operation is born by the owner if non-grounded wiring is utilized.
• The FDK100 Dehumidifiers must only be maintained and serviced by a qualified technician.
• The FDK100 Dehumidifiers are intended only for operation when oriented with the unit sitting on
its feet and level. Any other orientation could cause water to come in contact with the electrical
components. Remove plug before moving dehumidifier. If any water may have spread
throughout unit, the unit should be opened and allowed to dry thoroughly before reconnected to
electric and restarting.
• For proper operation, neither the inlet or discharge should be positioned against a wall. The
inlet requires a minimum of 12” clearance and the discharge needs a minimum of 24” clearance.
• For proper diffusion of air throughout the room, the dehumidifier should be positioned with the
sides against a wall and the inlet and discharge perpendicular to the wall.
• Do not insert any objects into the inlet or discharge. If service is required, call a qualified
technician. All work on unit should be down with the unit “off” and unplugged.
• Do not use water to clean unit exterior. Only use a damp cloth with unit unplugged.
• Do not use unit as shelf or device to hang clothes. This could cause damage to unit.
• The inlet filter generally needs cleaned once per month. Check unit on a weekly basis to ensure
that more frequent cleaning is not required.

2. DESCRIPTION OF THE MACHINE
Functioning
This dehumidifier is a refrigerating cycle dehumidifier: its functioning is based on a physical principle
according to which the air, coming into contact with a cooled surface, wets the surface by covering it
with humidity in the form of condensed drops, or ice with low ambient temperature. What really happens
is that a refrigerating machine maintains in a refrigerated state the coil through which is conveyed the
incoming air that, in this way, is cooled and dehumidified. Then the air, passing through a warm heat-
exchanger, heats up and returns in the room dehumidified and at a slightly higher temperature.
The FDK100 Dehumidifier is a refrigerating machine which utilizes its Electronic Board for Room
Humidity control and Defrosting Device control. When the relative humidity goes above the selected set
point, the dehumidifier will energize. Air, moved by an electric fan, is drawn across an evaporator coil.
The evaporator coil is cooler than the dew point of the air so moisture will condense out of the air.
Air is then reheated through the condenser coil and distributed back into the room at a little bit higher
temperature and lower Relative Humidity.
If the room temperature is lower than about 70°F, the
condensed moisture become ice; In this case
every roughly 30 minutes, a defrost device allows, tanks a Solenoid Valve, hot gas supplied by the
compressor enter the evaporator melting the ice.
3. INSTALLATION
The area to be controlled should be sealed with a vapor barrier. If installed in a crawlspace, all vents
should be sealed.
Place dehumidifier on level surface
CAUTION – Once unit is positioned, if the machine didn’t remain always in vertical position, wait
minimum 5 hours before turning the unit “on.” The Electronic board manages the compressor start and
stop to prevent the compressor starts too close.
Route drain line (3/4” ID tubing) to drain condensed water outside of the area.
Plug unit into 10 amp grounded outlet.
To operate unit, press Power key until unit energizes.
o Co
nfirm compressor is running and allow to run for minimum of 15 minutes
If under 70°F, a layer of ice will form on evaporator coil
If over 70°F, a layer of frost or water droplets will form on coil
After you’ve confirmed satisfactory operation of unit, humidistat should be set at desired position
for automatic operation.
NOTE: Humidistat settings are approximate only. For critical applications, you may want to confirm
actual settings with a psychrometer and adjust according.

3. CONTROL
Signalling panel
Units are provided with signalling light panel that indicates unit operational status. Below is
reported a brief description of their meaning.
Control panel
The Electronic card with microprocessor, control many functions:
Power LED; it’s on when the machine is in the ON state.
Alarm LED; it’s on when an alarm comes on. It turns off if the alarm is reset.
Working LED
; the LED is on when the compressor is running, blinks when the dehumidifier is
waiting to restart or is in defrost. It’s switched off when, in the ON state, the set of desired
humidity has been reached.
ON/OFF function
; plugged into the outlet (with ground wire!), the display turns on and shows the
relative humidity in the room.
The machine is in the OFF state when the Power LED is off. It’s in the ON state when the Power LED
is on.
When OFF, to switch on the dehumidifier, simply press the POWER key and depending on the
relative humidity set the machine starts working.
When the machine reaches the level of required moisture goes into stand-by mode: automatically
stops but remains in the ON state (POWER LED on).
If the humidity goes above the set point the dehumidifier starts again.
When ON to put the dehumidifier in OFF just press the POWER button (the display continues to
indicate the humidity in the room).
Note: putting the machine OFF and immediately ON, the compressor does not start immediately and
the Run led starts to flash. After a time of 210 seconds the
machine restarts.
HUMIDITY/TEMPERATURE SET function
; press one of the SET-/ +: the display starts flashing to
indicate the humidity set; continuing to press SET-/ + you can bring to the set of required moisture
(from 30% to 80%). After 4 seconds the display stops flashing and the new set of moisture is
detected by the control unit.
It’s possible to make the machine works regardless of the degree of moisture holding SET- until the
message "Cont" appears.
HOUR COUNTER: to show on the display the machine operating time push switch HOURS.

5.
FIRST STARTING OF MACHINE
Before starting the dehumidifier, make sure that the machine has been standing in vertical position
for at-least 5 hours. If one fails to observe this procedure, irreparable damage may be caused to the
compressor. Then one can proceed and connect the dehumidifier plug to a 115 V - one phase
power socket.
If the dehumidifiers is still off, set a lower value of humidity on the control panel .
After about 3 minutes the dehumidifier will start dehumidifying.
6. PERIODICAL MAINTENANCE
Air Filter Cleaning
The only required periodical maintenance is the cleaning of the filter once every month, or more
often if the environment is very dusty or the dehumidifier is working for many hours every day.
The cleaning must be done by placing the filter under a water jet with the drilled panel facing the
floor so that the water jet may push the filter towards the drilled panel.
After a few years running, may be necessary to make a cleaning of the warm heat exchanger
(condenser) by using compressed air. This operation must be done by a specialized technician.
This cleaning will improve the performances and the long life of the machine.
Note: You can require spare filters from your dealer's service.
PROBLEM PROBABLE CAUSE and CORRECTIVE ACTION
+ “Lo t”
It occurs for two possible reasons: the environment temperature is too low or
the defrost cycles are not able to melt the ice in the battery. To reset put the
dehumidifier above 50 ° F, if not reset put the dehumidifier off with POWER
button and unplug the machine.
+ “LoPt”
Possible lack of gas in the circuit. The alarm resets automatically after 210
seconds.
If the alarm does not reset simultaneously press and SET HOURS + for 10
seconds. If the problem occurs again, call for service.
+ “HI t”
Combination of temperature and humidity too high.
The alarm resets automatically when the temperature drops.
“Prob”
Malfunction humidostat. In any case, the machine continues to operate. Contact
the service to replace the humidistat.
+ “Pro1” o
“Pro2” o “Pro3”
Malfunction of one of the three temperature probes. The dehumidifier goes into
stand-by mode. Contact the service to replace the probes.
