If LED indicates alarm, the number of flashes helps identify root
cause.
Comp.:
When the compressor is running normally, the LED will be solid
green.
If the system goes into self-test mode, the LED will flash green.
Fan (In):
When the inner fan is running normally, the LED will be solid green.
Fan (Out):
When the outer fan is running normally, the LED will be solid green.
C: Touchpad controls:
↑: UP or increase
↓: DOWN or decrease
SET: Parametric setup
ON/OFF ESC: Power on/off or back

Self-Test
1. Press the SET button to enter parametric setup mode.
2. Enter the correct password into the 7-digit display and press SET button; display
shows d01. (Default password: 000)
3. Press SET button to enter detailed parametric setup.
4. Press UP button to choose d1.4, then press SET button to execute auto self-test.
5. If system goes into self-test mode, Comp. LED will flash green.
6. Auto self-test duration is about five minutes, exlusive of three-minute compressor
test.
7. The test process checks that EEPROM, NTC sensor, inner fan, outer fan and
compressor are running correctly.
8. Watch for any alarm during test process. In case of alarm, note number of
flashes to help identify root cause.

Fault Analysis and Processing
Fault State
Analysis of the Reasons
Solutions
Power on, and the
cabinet temperature
is too high but the
air conditioner is not
working
•Power failure or no
power.
•The target temperature is
higher than inside
temperature.
•System failure.
•Check the power supply and
the electric circuit.
•Re-set the target temperature
according to the system
requirement.
•Please contact Delta or
authorized Delta service
agent.
The air conditioner
is running but the
cabinet temperature
is still high, no
obvious cooling
effect.
•The air conditioner
capacity is not match the
load of the system.
•The ambient
temperature is too high.
•Low efficiency of the
condenser.
•Other system failure
•Check the heating load of the
system.
•Ensure the air conditioner is
operating in correct
temperature range.
•Clean the condenser.
•Please contact Delta or
authorized Delta service
agent.
The air conditioner
stop operating, and
there is no alarm
signal.
•The inside temperature
is lower than the target
temperature.
•Other system failure.
•Re-set the target temperature
according to the system
requirement.
•Please contact Delta or
authorized Delta service
agent.

5. Mechanical Feature
Thermal Path and Airflow Baffle
Internal and external air flow circulation is shown in below diagram. Counterflow
design prevents mixing of internal and external air flows, but waste heat can still
be dissipated from cabinet to the ambient outside air. An internal temperature
sensor has been placed in the return air stream to provide reliable temperature
measurement, and for safe operation.

The heated air inside the cabinet will be cooled by the evaporator. Waste heat
absorbed by the refrigerant will be dissipated through the condenser at the
external side.

6. Maintenance
SHUT DOWN the power before performing regular maintenance or component
replacement.
6.1 Maintenance Cycle
Use a brush and low pressure air to remove any dust or debris in the air inlet and
air outlet openings. Suggested maintenance cycle is indicated in the table below:
Check Item
Step Description
Maintenance Cycle
Wiring
Visually check if the wiring is loose
12 months
Fan
abnormalities
Turn the fan to check for smooth rotation
and for any abnormal noise
12 months
Drainage
pipe
Visually check if the drainage opening is
blocked
6 months
Condenser
