Applicable models:  AM5O-120HPDC1  AM5O-12 0HPDC1

Please read this manual carefully before the installation and operation of this product.

 

User Notice ◆ The total capacity of the indoor units which runs at the same time can not exceed 150% of that of the outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be poor.

◆ Switch the main power on 8 hours before start the unit, helpful for a successful startup. ◆ It is a normal phenomenon that the indoor unit fan will still run for 20~70 seconds after the indoor unit receives the “stop” signal so as to make full use of after-heat for the next operation.

◆ When the running modes of the indoor and outdoor units conict, it will be indicated on the display of the wired controller in ve seconds and then the indoor unit will stop. In this case, they can back to the normal condition by harmonizing their running modes: the cooling mode is compatible with the dehumidifying mode and the fan mode can go with any other mode. If the supply power fails when the unit is running, then the indoor unit will send the “start” signal to the outdoor unit three minutes later after power recovery.

◆ During installation, the communication cable and the power cord must not be twisted together but instead separated with an interval of at least 2cm; otherwise the unit is likely to run abnormally.

◆ Cautions for the Debugging and Maintenance Personnel: During debugging and maintenance, prior to the startup of the compress make sure the heating  belt of the compressor has been energized for at least eight hours! Once the compressor is started, it must be guaranteed that it works continuously for at least 30 minutes, otherwise it would be damaged! This series outdoor units are matched with the free macth series R410A GMV multi VRF indoor units under the same working conditons exported to European Union. This product must not be disposed together with the domestic waste. This product has to be disposed at an authorized place for recycling of electrical and electronic appliances.

Working Principles of the Unit

Ⅲ Working Principles of the Unit Schematic Diagram of Free Match Series Inverter Heat Pump Multi VRF System M

Fig. 10 Schematic Diagram of Free Match Series Inverter Inverter Heat Pump Multi VRF System The outdoor and indoor units start to work once the power is switched on. During the cooling operation, the low temperature, low pressure refrigerant gas from the heat exchanger of each indoor unit gets together and then is taken into the compressor to be compressed into high temperature, high pressure gas, which will soon go to the heat exchanger of the outdoor unit to exchange heat with the outdoor air and then is turned into refrigerant liquid. After passing through the throttling device, the temperature and pressure of the refrigerant liquid will further decrease and then go the main valve. After that, it will be divided and go to the heat exchanger of each indoor unit to exchange heat with the air which needs to be conditioned. Consequently, the refrigerant liquid become low temperature, low pressure refrigerant gas again. Such a refrigeration cycle goes round and round to achieve the desired refrigeration purpose. During the heating operation, the four-way valve is involved to make the refrigeration cycle run reversely. The refrigerant radiates heat in the heat exchanger of the indoor unit (so do the electric heating devices) and absorb heat in the heat exchanger of the outdoor unit for a heat pump heating cycle so as to achieve the desired heating purpose.

Function Description

Ⅶ Function Description Refrigerant Recovery

The refrigerant can be recovered from either the indoor unit or the outdoor unit. From the outdoor unit: it is available to recover the refrigerant from the outdoor unit by pressing “SW3”for a long time period. From the indoor unit: when the unit is powered on and runs under the COOL mode, it is available within ve minute to go the refrigerant recovery mode by pressing three times the “LIGHT” button on the wireless controller in three seconds with “F0”displayed. How to quit the refrigerant recovery: When the refrigerant recovery has started, it will quit when the “SW3” is pressed down for a long time  period or there is a signal from the wireless controller or it has run for ten minutes. Forcible Defrosting

How to activate this function: when indoor unit runs under the heating mode and at 16℃ , it will activate the forcible defrosting by pressing the “+”and “-” buttons alternately three times in ve seconds. How to quit this function: the function will quit when the mode of indoor units conicts. Switchover of the Defrosting Modes

Under the unit is under the “Off” status, if “H1” is not displayed on the wireless controller, then the unit will go to the defrosting mode 1 when it is turned on through the wireless controller. Under the unit is under the “Off” status, if “H1” is displayed on the wireless controller, the unit will go the defrosting mode 2 when it is turned on through the wireless controller. Under the unit is under the “Off” status, it is available to switch over the defrosting mode 1 and defrosting mode 2 by pressing the “Mode” and “Blow” buttons simultaneously.
