INTRODUCTION
Designed for a wide range of applications, the Kompact is a rugged, industrial unit, which
utilizes an energy-efficient compressor and a compact portable design to provide easy efficient
drying.
The Kompact has a number of special features:
•High efficiency rotary compressor
•Ebac’s “Hot Gas” defrost system
•Hours run meter
•Integral pump out system
•Provision for permanent drainage
•All galvanized interior
•Exterior epoxy powder-coated finish
•Rugged trolley for portability
•Extra long power cord
The fan draws the moist air through the cold evaporator coil, which cools the air below its dew
point. Moisture forms on the evaporator coil and is collected in the condensate tray, which is
equipped with a permanent drain. The cooled air then passes through the hot condenser coil
where it is reheated using the same energy removed during the cooling phase, plus the additional
heat generated by the compressor. The air is, therefore, discharged from the dehumidifier at a
slightly higher temperature with a lower absolute humidity than that which entered. Continuous
circulation of air through the dehumidifier gradually reduces the relative humidity within the
area.
The Kompact dehumidifier is a rugged, reliable drying unit designed to operate effectively over
a broad range of temperature and humidity conditions. An active hot gas defrost system,
controlled by an electronic timer, guarantees positive de-icing, thereby optimizing operation at
low temperatures.
The unit incorporates a welded steel chassis and is finished in an epoxy coating for resilience to
damage caused by rough handling.
The dehumidifier unit is fitted with a transformer which will allow the unit to operate on either
110volts or 230volts 1ph 50Hz power supply.
All electrical components within the dehumidifier are rated for 110volts, for safety reasons. The
voltage change over (selector switch) switch, can be found at the top of the electrical panel,
internal to the unit. Remove the side cover for access.

OPERATION
The following procedures should be followed to test the Kompact for correct operation:
1. After unpacking, examine all external features to confirm damage-free shipment.
Report all defects and damage at once. Ensure the correct voltage has been selected.
2. Check dehumidification process as follows:
CAUTION: DO NOT REMOVE COVERS WHEN UNIT IS IN
OPERATION.
A. Place unit on a level surface.
B. Start up unit by switching to “ON”.
C. Check that the compressor is running.
D. Leave the machine running for 15 minutes.
E. Observe the evaporator coils through the rear upper grille, to confirm frost
formation.
i. If the air temperature is below 25ºC, an even coating of frost should
cover the entire evaporator coil.
ii. If the air temperature is above 25ºC, frost and/or droplets of condensed
water should cover the entire evaporator coil.
F. After continuous running time of approximately 55 minutes, unit will enter “Hot
Gas” defrost mode for several minutes and then automatically return to normal
operation.
If, after carrying out the above procedures, the unit does not appear to function properly, refer to
the Trouble Shooting section, which follows, or contact the Factory Service Center.
CAUTION: Once the unit has been switched off, wait at least five
minutes before restarting.
After using the Kompact, turn it off for five minutes to allow the condensate on the coils to drain
into the pump reservoir, then turn it back on and press the momentary purge switch for twenty to
thirty seconds to evacuate the water from the pump reservoir.

ROUTINE MAINTENANCE
WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE
HAS BEEN DISCONNECTED BEFORE CARRYING OUT
ROUTINE MAINTENANCE ON ITEMS 1, 2, 4, AND 5.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be
performed as follows:
1. Clean the surface of the evaporator and condenser coils by blowing the dirt out from
behind the fins with compressed air. Hold the nozzle of the air hose away from the
coil to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS.
2. Check that the fan is firmly secured to the motor shaft and that the fan rotates freely.
The fan motor is sealed for life and therefore does not need oiling.
3. To check the refrigerant charge, run the unit for 15 minutes and briefly remove the
top cover. The evaporator coil should be evenly frost coated across its surface. At
temperatures above 78°F, the coil may be covered with droplets of water rather than
frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates
loss of refrigerant gas or low charge. During this inspection, check visually to ensure
that the pump rollers are turning.
4. Check all wiring connections, including mains cable for damage or loose connections.
5. To check the operation of the defrost system, switch the machine on and leave it
running for approximately 55 minutes. The machine will then enter “Hot Gas”
defrost mode for approximately 5 minutes before returning to normal operation. If
the unit will not defrost, the printed circuit timer board may be defective or the by-
pass valve may be inoperable.
IF ANY OF THE PRECEDING PROBLEMS OCCUR,CONTACT THE EBAC SERVICE CENTER PRIOR TO
CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

REPAIRS
1. Should an electrical component fail, consult the Factory Service Center to obtain the
proper replacement part.
2. If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration
technician to correct the fault. Contact the Factory Service Center prior to initiating
this action.
Any competent refrigeration technician will be able to service the equipment. The
following procedure must be used:
a. The source of the leak must be determined and corrected.
b. The machine should be thoroughly evacuated before recharging.
c. The unit must be recharged with refrigerant measured accurately by weight.
d. For evacuation and recharging of the machine, use the crimped and brazed
charging stub attached to the side of the refrigerant compressor.
The charging stub should be crimped and rebrazed after servicing. NEVER allow
permanent service valves to be fitted to any part of the circuit. Service valves
may leak causing further loss of refrigerant gas.
3. The refrigerant compressor fitted to the dehumidifier is a durable unit that should
give many years of service. Compressor failure can result from the machine losing its
refrigerant gas. The compressor can be replaced by a competent refrigeration
technician.
Failure of the compressor can be confirmed by the following procedure:
a. Establish that power is present at the compressor terminals using a voltmeter.
b. With the power disconnected, check the continuity of the internal winding by
using meter across the compressor terminals. An open circuit indicates that the
compressor should be replaced.
c. Check that the compressor is not grounded by establishing that a circuit does not
exist between the compressor terminals and the shell of the compressor.
