System Diagram for Cooling-and-Heating Unit

Capillary

4-way valve

Evaporator Condenser

Gas-liquid

Cooling separator Compressor
Heating

Switch on the power to start the unit. Low-pressure refrigerant vapor from evaporator is absorbed into the
compressor, where it is compressed into high-temp. and high-pressure gas. The gas refrigerant is then
diverted to condenser, where it is liquidized after heat exchange with outdoor air. After that, the liquidized
refrigerant flows through capillary for decrease of temperature and pressure and then enters into
evaporator, where it becomes low-temp. and low-pressure refrigerant vapor after heat exchange with
indoor air to be regulated. This process is repeated in cycle to achieve the purpose of cooling. (Under
heating mode, the 4-way valve will change the flow of refrigerant, so that the condenser absorbs heats
and the evaporator gives out heats, thus to achieve the purpose of heating).

7.1.5 Protection

7.1.5.1 Indoor Antifreeze Protection

 If E2 is displayed under cooling mode, the compressor, outdoor fan and indoor fan will be stopped, and the swing

motor will maintain its original status. When evaporator temperature is higher than 6 and the compressor has been ℃

stopped for 4 minutes, the display will resume and the controller will run under preset mode.

 Under dehumidifying mode (i.e. run 6 minutes and stop 4 minutes), if it is detected within 3 minutes successively that

the tube temperature is lower than -2 after the compressor has been running for 3 minutes, the c℃ ompressor and

outdoor unit will be stopped, the indoor fan will run at low speed, and E2 will be displayed. When tube temperature is

higher than 6 and the compressor has been stopped for 4 minutes, the display will resume and the controller will ℃

run under preset mode.

7.1.5.2 Compressor High-pressure Protection

If high-pressure protection is detected within 3 seconds successively, all loads will be closed, all key-press and remote
control signals will be shielded, and E1 will be displayed. When it is detected within 6 seconds successively that the
compressor has released high-pressure protection, shielding of key-press signal will be removed but E1 will be still
displayed. To clear off E1 display, you have to press ON/OFF key to switch off the unit and press it again to restart.

7.1.5.3 Compressor Low-pressure Protection

 When it is detected that the low-pressure switch is off, the complete unit will be stopped and be automatically

restarted after 3 minutes. If E3 is displayed, the unit cannot be restarted automatically, in which case you have to
press ON/OFF key to switch off the unit and press this key again to restart.

－21－

 If it is detected that the low-pressure switch is off when the compressor is stopped, the complete unit will be stopped,

E3 will be displayed and the unit cannot be restarted automatically. You have to press ON/OFF key to switch off the
unit and press this key again to restart.

7.1.5.4 Exhaust Pipe High-temp. Protection

 After the compressor is started, if the exhaust temperature is too high or exhaust sensor is in short circuit (or open

circuit), the unit will be stopped when the indoor ambient temperature reaches the preset value.

 After the compressor is stopped for 3 minutes, the complete unit will be restarted when the exhaust temperature is

resumed to normal.

 In case of above issue, the complete unit cannot resume its operation and E4 will be displayed. You have to press

ON/OFF key to switch off the unit and press this key again to resume operation under preset mode.

7.1.5.5 Indoor Overtemperature Protection

 If it is detected that the evaporator tube temperature is too high under heating mode, the outdoor fan will be stopped.

When the evaporator tube temperature resumes to normal, the outdoor fan will be started.

7.1.5.6 Low-voltage Protection

 If the current is detected over 22A as the compressor is started, the unit will be stopped when indoor ambient

temperature reaches preset value. The compressor will automatically resume to its original operating status after it is
stopped for 3 minutes. If E5 is displayed, the compressor cannot resume to its original operating status automatically,
in which case you have to press ON/OFF key to switch off the unit and press this key again.

① From the remote controller, you can press temperature selection key (+) to enter into compulsory heating mode, in

which case all the keys on front panel and remote controller will be shielded, all loads will be started and the indoor

fan will run at high speed. If it is detected that ambient temperature is in open circuit or higher than 105 , or that ℃
evaporator temperature is in open circuit or higher than 105 , the buzzer will beep. After five minutes, the unit will be ℃

stopped and enter into normal standby status.

② From the remote controller, you can press temperature selection key (-) to enter into compulsory cooling mode, in

which case all the keys on front panel and remote controller will be shielded, all loads except the 4-way valve will be
started and the indoor fan will run at high speed. If it is detected that ambient temperature is in open circuit or higher

than 105 , or that evaporator temperature is in open circuit or higher than 105 , the buzzer will beep. After five ℃℃

minutes, the unit will be stopped and enter into normal standby status.
The functions stated in 1 and 2 are only for test purpose. Compulsory heating function is not available for cooling-only
unit.

7.1.5.9 Indicator

 Power indicator: It is bright when energized and black when de-energized. It will blink under indoor antifreeze

protection, compressor high-pressure protection, low-voltage protection and defrosting.

 Cooling indicator: It is bright under cooling mode, dehumidifying mode, auto cooling mode or auto dehumidifying

mode. It is black under other modes.

 Heating indicator: It is bright under heating mode and auto heating mode. It is black under other modes

7.1.5.10 Power-OFF Memory Function

Memory function includes the mode, swing, preset temperature, preset fan speed, Auto ON/OFF (If the power is cut off
before the preset time for AUTO ON/OFF, the timer will count the time again once the power is resumed. If the power is
cut off after the preset time for AUTO ON/OFF, the unit, once energized again, will run under the mode after preset AUTO
OFF time).
Once energized again after any de-energization, the unit can be automatically restarted according to the memory.

Warning

z Be sure to stop the unit and plug out the power before cleaning your air

conditioner. Otherwise, electric shock may happen.

z Never splash water on the indoor unit, this may cause the risk of

electric shock.

z Volatile liquids such as thinner or gasoline will cause damage to the

appearance of air conditioner. (Only use soft dry cloth or wet cloth
soaked with neutral detergent to clean the indoor unit).

9.1 To clean the filter

Remove the filter and clean with vacuum cleaner. If

very dirty, wash with warm water (below 45℃) that is

added with neutral detergent. Fully dry the filter before
reinstallation.

Suggestion: Too dirty filter will reduce air inflow and result in system overload, causing 6% more
consumption of power. Therefore, it is quite necessary to clean the filter regularly.

9.2 To clean the equipment and components

Use dry and soft cloth or vacuum cleaner to clean the
air conditioner and remote controller. If wet cloth is
used, please wipe it dry after cleaning.

Warning: Never expose the front grill or air filter directly under the sun. Never clean it with hot

water over 45℃ or dry it on fire, (as this will cause decoloring, fire or deformation).

9.3 When using the air conditioner

Check for any foreign articles that may obstruct the air into
or out of the indoor and outdoor unit.
If the unit is operating without air filter, dust will deposit and
cause trouble to the unit. Generally, be sure to install filter
before operating the unit.
Check the drainage pipe for bend or damage.
Check the equipment for normal and correct installation.

9.4 When the air conditioner is out of service

Pull off the plug and disconnect the power.
Clean the filter, equipment and components.
Start the fan for 2 to 3 hours to clean and dry the
inside of the equipment.

supply conditions such as adding regulated power
supply.

When turning the
air-conditioning unit to
the “ON”status, trip of
