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.

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. Connect the
power cable to a grounded 15 Amp electrical outlet.
2. Check dehumidification process as follows:
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 78°F, an even coating of frost
should cover the entire evaporator coil.
ii. If the air temperature is above 78°F, 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.
After using the Kompact, turn it off for five minutes to allow the condensate on
the coils to drain into the pump reservoir, then press the momentary pump
purge switch for twenty to thirty seconds to evacuate the water from the pump
reservoir.
CAUTION:
DO NOT REMOVE COVERS WHEN UNIT IS IN OPERATION
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.

ROUTINE MAINTENANCE
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.
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.
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.
WARNING:
ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN
DISCONNECTED BEFORE CARRYING OUT ROUTINE
MAINTNENANCE ON ITEMS 1, 2, 3, 4 & 5

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.
