1. 2. 3. 4. 5. 6. 7. 8.

Engage dealer or specialist for installation and servicing. If installation or servicing done by the user is defective, it will cause water leakage, electrical shock or fire. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leakage, fire or electrical shock. Install at a strong and firm location which is able to withstand the set's weight. If the strength is not enough or installation is not properly done, the set will drop and cause injury. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire. Use the specified cable and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock. When connecting the piping, do not allow air or any substances other than the specified refrigerant to enter the refrigeration cycle. Otherwise, this may lower the capacity, cause abnormally high pressure in the refrigeration cycle, and possibly result in explosion and injury. Thickness of copper pipes used must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.

10. It is desirable that the amount of residual oil is less than 40 mg/10 m.
11. Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
The equipment must be earthed. It may cause electrical shock if grounding is not perfect. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.

11.4. Operation Control

(For 11.4.1 to 11.4.7 information applies only to Cooling and Soft Dry Operation)

11.4.1.

Restart Control (Time Delay Safety Control)
When the thermo-off temperature (temperature which compressor stops to operate) is reached during:- Cooling operation - the compressor stops for 3 minutes (minimum) before resume operation. - Soft Dry operation - the compressor stops for 6 minutes (minimum) before resume operation. If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operation stop, although the unit is turn on again within the period. This phenomenon is to balance the pressure inside the refrigerant cycle.

11.4.2.

60 Seconds Forced Operation
Once the air conditioner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intake air temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at the remote control is permitted. The reason for the compressor to force operate at minimum 60 seconds is to allow the refrigerant oil run in a full cycle and return back to the outdoor unit.

11.4.3.

7 Minutes Time Save Control
The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between the compressor ON temperature (A) and compressor OFF temperature (B) during the period. This phenomenon is to reduce the built up humidity inside a room.

11.4.4.

Freeze Prevention Control
If the temperature of the indoor heat exchanger falls below 2C continuously for 4 minutes or more, the compressor turns off. The fan speed setting remains the same. This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid form returning to the compressor. Compressor will restart again when the indoor heat exchanger temperature rises to 10C (Recovery). Restart control (Time Delay Safety Control) will be applied in this Control if the recovery time is too short.

11.4.5.

Compressor Reverse Rotation Protection Control
If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and indoor heat exchanger is 2.5C or less for continuous 2 minutes, compressor will stop and restart automatically. Time Delay Safety Control is activated before the compressor restart.
T = Intake air temperature - Indoor heat exchanger temperature This is to prevent compressor from rotate reversely when there is an instantaneous power failure.

11.4.6.

Starting Current Control
When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start to operate at 1.6 second later. The reason of the difference is to reduce the starting current flow.

11.4.7.

Dew Prevention Control
Purpose is to prevent dew formation on indoor unit air discharge area. The following conditions occur for 30 minutes continuously, dew prevention will activate: - Remote Control setting temperature is less than 25C. - Compressor is on. - Cooling operation mode. 28
- Indoor fan motor operate at low fan speed or QLo. This control is cancelled immediately when above condition is changed. Dew prevention is control by: 1. Lo fan speed Lo fan is changed to Lo+ fan 2. QLo fan speed
11.5. Indoor Fan Speed Control
Indoor Fan Speed can be set using remote control.

11.5.2.

Automatic Fan Speed Control
When set to Auto Fan Speed, the fan speed is adjusted between maximum and minimum setting as shown in the table. - Fan speed rotates in the range of Hi, Me and Lo-. - Deodorizing Control will be activated.
- Auto Fan Speed during cooling operation: 1. Indoor fan will rotate alternately between off and on as shown in below diagram. 2. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing purpose. 3. For the first time the compressor operate, indoor fan will be switched to Hi fan speed from Lo- after 70 seconds from the start of compressor. This cause the room temperature to achieve the setting temperature quickly. 4. During compressor stop, indoor fan will operate at Lo- for the beginning 20 seconds to prevent higher volume of refrigerant in liquid form returning to the compressor. 5. After the compressor at turn off condition for 3 minutes, indoor fan will start to operate at Lo- to circulate the air in the room. This is to obtain the actual reading of the intake air temperature. 6. When the compressor resume operation, indoor fan will operate at Me fan speed (after 70 seconds from the restart of compressor) to provide comfort and lesser noise environment.

Auto Fan Speed during Soft Dry operation: 1. Indoor fan will rotate alternately between off and Lo-. 2. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing purpose. 3. When compressor at turn off condition for 6 minutes, indoor fan will start fan speed at Lo- to circulate the air in the room. This is to obtain the actual reading of intake air temperature.

11.5.3.

Manual Fan Speed Control
Manual fan speed adjustment can be carried out by using the Fan Speed selection button at the remote control. There are 3 types of fan speed setting: Lo, Me, Hi.
11.6. Outdoor Fan Speed Control
There are 2 speeds for outdoor fan motor, outdoor fan speed can be changed to Hi or Lo according to outdoor temperature (V28EK). When the air conditioner is turned on, the compressor and the outdoor fan will operate simultaneously. Likewise, both compressor and outdoor fan will stop at the same time if the unit is turned off.

11.11.2. Error Detection Control
The error detection control is to inform user that error occurs at ionizer system and repairing job will be needed. There are two types of error detection control: a. When Ionizer is ON - If ionizer feedback = Lo for 24 times within 11hr 30min, ION LED blinks continuously. b. When ionizer is OFF - If ionizer feedback = Hi, ION LED blinks continuously. During ionizer at breakdown condition, if ionizer feedback voltage = Lo (become normal), ION LED will stop blinking. The error detection control can be reset by: i) Pressing the OFF/ON operation button to switch the operation OFF. ii) Pressing the Auto Operation button to force the operation OFF. iii) Setting the OFF Timer to stop the operation (Not applicable when ionizer is OFF).

11.12. Timer Control

There are 2 types of timer, ON and OFF timer. Both ON and OFF timer can be set by pressing ON or OFF button respectively. By pressing ON/OFF operation button, ON Timer or OFF Timer will not be cancelled. To cancel the previous timer setting, press CANCEL button. To activate the previous timer setting, press SET button once again. If main power supply is switched off, the timer setting will be cancelled.

(Note) All parts are supplied from PHAAM, Malaysia (Vendor Code: 061). O marked parts are recommended to be kept in stock.

According to a new EC Directive, the indication of the Energy Efficiency classification on household heatpumps became compulsory. This aims to provide consumers with clear and objective information regarding energy-saving, and to encourage them to select products that are environmentally friendly. An Energy Label, like that shown in the sample below, will be provided in shop displays. In the label, the equipment is rated, with "A" being the most efficient. You may notice these labels and ratings appearing soon in shops that sell heatpumps. For easy understanding, the following information will be indicated for each model. Energy Label Heatpump

Feature Explanations

Healthy Air Quality
e-ion Air Purifying System Active e-ions are shot out to catch dust and inactivate airborne bacteria and mould. The positively charged mega filter attracts dust to thoroughly clean the room. SUPER alleru-buster filter The SUPER alleru-buster filter combines three effects in one anti-allergen, antivirus, and anti-bacteria protection to keep room air clean and healthful.
Inverter Control An inverter heatpump provides optimum power control, which is impossible for conventional units. The secret lies in the inverter circuit. By changing the frequency of power supply, this circuit alters the rotation speed of the compressor, which is the heart of the heatpump. The result is comfortable, economical operation. Heating possible at -20C Providing outstanding cold climate performance, Panasonic heatpumps let you enjoy stable heating even when the outside temperature is below freezing.

Convenient

Soft Dry Operation Mode Starts with cooling to dehumidify. Then provides continuous breeze at low frequency to keep room dry without much change in temperature. Wide & Long Airflow Vane This newly designed vane has been integrated with the louver to send the air further. Sends air to every corner of the room to keep the whole room comfortable. Manual Horizontal Airflow Direction Control Auto Changeover (Inverter) Auto Changeover Sensors measure the room and outside temperatures periodically. Based on these temperatures and the set temperature, the microcomputer determines the most suitable operating mode as time passes. Auto Changeover System

Patrol Sensor Air is monitored both during the unit operation and when its switched off. When dirt is detected, the air purifying function is started to immediately clean the air in the room. Anti-Mould, One-Touch Air Filter Odour-Removing Function With this function, there's no unpleasant odour when the unit starts up. That's because the fan remains off momentarily, while the source of the odour inside the unit is suppressed.
