(5) SUPER COMPLETE SAFTY PROTECTIONS FOR SAFE OPERATION.
5-1 Safety protections built in the system control
For Heat Pump and Cool only Systems
- Auto restart Feature with backup memory.
When the power failure is happened during system operation, the micro of printed circuit board will memorize
the operation setting.
After the power is recovered, the system operates automatically ( without remote control after compressor
time delay ), according to the previous operation settings.
- 3 (Three) minutes time delay between compressor turning off and turning on.
- 3 (Three) minutes minimum operation time between compressor turning on and turning off during Cool or Dry
mode to allow sufficient time for lubricating oil to return back to compressor.
3 to 6 (Three to Six minutes) minimum operation time between compressor turning on and turning off during Heat
mode to allow sufficient time for lubricating oil return back to compressor.
- Refrigerant leak protection by sensitive thermistors mounted on the indoor and outdoor coils.
- Frost prevention of indoor coil when the system is operating in cool mode with excessive dirt on the indoor coil
and / or clogged air filters and when the system is operating in cool mode at low ambient temperature.
- Battery warning sign appears on the display of remote control to remind the customer that the batteries in the
remote control are running down.
- Complete Self-diagnostic function to detect malfunctions due to incorrect installation or abnormal use.
When the system is on and in a malfunction, the fault code will be flashed out on the unit display located on the
indoor unit.
For Heat Pump Systems
- Cold draft protection when the system is operating in heat mode to prevent cold air from blowing into the space
to be air-conditioned and also to speed up the heating.
- Defrost protection of outdoor coil when the system is operating in heat mode at very low ambient temperatures.
- High temperature protection of outdoor coil when the system is operating in heat mode at high ambient
temperature.
5-2 Safety protections built in the components of outdoor unit
- Internal overload to protect the compressor motor winding against excessive temperature and / or excessive current.
- Internal thermal overload to protect the outdoor motor winding against excessive temperature.
- Internal pressure sensitive interrupter to protect the dual run capacitor for both compressor and outdoor motor
against short circuiting.
- Components of outdoor unit comply with international standards of performance, safety and reliability.
5-3 Safety protections built in the components of indoor unit
- Internal thermal overload to protect the indoor motor winding against excessive temperature.
- Internal pressure sensitive interrupter to protect the run capacitor for indoor motor against short- circuiting.
- Components of indoor unit comply with international standards of performance, safety and reliability.

8-6 FLEXIBLE OUTDOOR UNIT LOCATION WITH RESPECT TO INDOOR UNIT LOCATION
The following data refers to the use of refrigerant piping lines of diameters equivalent to that use in units
where :
L = Maximum length of refrigerant piping lines between outdoor and indoor unit.
H = Maximum vertical distance between outdoor and indoor units.
(A) OUTDOOR UNIT BELOW INDOOR UNIT :
a. Suction line should rise above height of Indoor unit to shape a liquid trap in an inverted
loop before descending to outdoor unit to prevent liquid refrigerant from draining into
compressor during shutdown.
b. Slop tubing towards the outdoor unit with a fall of at least (6mm) to (305mm).

(10) SYSTEM TEST FUNCTION, WHICH IS USED BY INSTALLER AND ALSO
BY SERVICEMAN TO VERIFY THAT THE SYSTEM IS WORKING CORRECTLY.
This test initiated via the remote control regardless of set temperature and room
air temperature.
The system test function is initiated via the remote control.
Test mode is used to put the system in demand regardless of set temperature and room air
temperature.
For example, if the service man is installing a cool only system in the winter, and the room
air temperature is 15 °C, the service man would have to return when the room air
temperature was warmer. This test allows for the service man to test the system anytime by
forcing demand.
When the remote control in off position, push once the buttons (Λ) and ( ) on the remote
control for more than 5 seconds until symbol “Src” appears on the display this means test
mode.
Then the three minutes time guard for compressor is ignored and the unit will start
immediately based on the original setting before starting test mode.

11. COMPLETE SELF DIAGNOSTIC FUNCTION
WHICH IS USED BY INSTALLER AND ALSO BY SERVICEMAN
TO DETECT AND CORRECT MALFUNCTIONS
EXPLAINATION OF SELF-DIAGNOSTIC FUNCTION FOR SIZES 18K – 24K
-
Self-diagnostic function is the key for success of air conditioner operation.
-
The printed circuit boards existing inside the indoor unit are equipped with selfdiagnostic function to detect malfunction and automatically stops the operation at
the air conditioner.
Once a malfunction is detected, the diagnostic control section will force the system
mode to OFF for 3 minutes. After the OFF delay, system mode releases and
allowed returning to its normal state. The system will be allowed to restart on its
own.
The diagnostic control section will allow the system to fail 5 consecutive times
before shutting down the system. If the system is performing an active defrost,
both the compressor drive and reversing valve malfunction test will be cancelled
and reinitiated after the following compressor OFF-ON cycle.
The Unit on lamp is scanned every half-second and the error codes are displayed
by the flashing frequency of unit on lamp. The error codes are displayed during
SHUT-OFF (3 minutes off and after the 5th retry failure).
