BS Plug Wiring
Wiring Instructions: Should it be necessary to change the plug please note the wires in the mains lead are coloured in accordance with the following code:
BLUE - NEUTRAL
BROWN - LIVE
As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:
- The BLUE wire is the NEUTRAL and must be connected to the terminal which is marked with the letter N or coloured BLACK.
- The BROWN wire is the LIVE and must be connected to the terminal which is marked with the letter L or coloured RED.
- The GREEN/YELLOW is the EARTH and must be connected to the terminal which is marked with the letter E or ⊕ or coloured GREEN or GREEN/YELLOW.
- Always ensure that the cord grip is positioned and fastened correctly.
If a 13 Amp (BS 1363) fused plug is used it must be fitted with a 13 Amp fuse. If in doubt consult a qualified electrician. (For 9000BTU and 12000BTU unit only.)
(For 18000BTU use 20 Amp (fuse) supply from the main.) (For 24000BTU use 32 Amp (fuse) supply from the main.)
Wiring for a 13 Amp Plug (BS1363)
Please note. The Earth Terminal is marked with the letter E or 🌐 Earth Symbol.

Working principle and special functions for Cooling
Principle:
Air conditioner absorbs heat in the room and discharges the heat through the outdoor that indoor ambient temperature decreased, its cooling capacity will increase or decrease by outdoor ambient temperature.
Anti-freezing function:
If the unit is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0^ C indoor unit microcomputer will stop the compressor running to protect the unit.
Working principle and special functions for Heating
Principle:
* Air conditioner absorbs heat from outdoor and discharges to indoor, in this way to increase room temperature. This is the heat pump heating principle, its heating capacity will be reduced due to outdoor temperature decrease.
* If outdoor temperature becomes very low, please operate with other heating equipments.
Defrosting:
* When outdoor temperature is low but high humidity, after a while running, frost will form on outdoor unit, that will affect the heating effect, at this time, the auto defrosting function will activate, the heating will stop for 8-10 mins.
* During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
* During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor. This is due to the defrosting, it isn't a malfunction.
* After defrosting finished, the heating will resume automatically.
The climate type of this unit is according to the nameplate.
The external static pressures at which the appliance was tested should be zero Pa.

Notices for use
Anti-cool wind function:
In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't arrive at certain temp, indoor fan will not act, in order to prevent cool wind blowing(within 2 mins):
- Heating starts. 2. After Auto Defrost finished. 3. Heating under the low temperature.

④
⑤ Adopt the special shield to cover the outdoor unit, avoid the rain water, dust enter into the unit.


CAUTION
Don't attempt to repair the air conditioner by yourself, it can cause an electric shock or fire. Please check the following items before asking for repair, it can save your time and money.
| Phenomenon | Troubleshooting |
Not operate immediately when the air conditioner is restarted.![]() | ● Once the air conditioner is stopped, it will protect itself. |
There's unusual smell blowing from the outlet after operation is started.![]() | ● The unit has no peculiar smell by itself. If it has that is due to the smell accumulated in the ambient.● Solution method: Cleaning the filter.If problem is still there, you need to service the air conditioner. (Please contact your deale or EcoAir.) |
Sound of water flow can be heard during the operation.![]() | ● The air conditioner is started, when it is running the compressor started or stopped running, or the unit is stopped, sometimes there is swoosh or gurgle, the sound is due to refrigerant flowing This is not a malfunction. |
In COOL mode, sometimes the mist emitted from the air outlet vent.![]() | ● When the indoor temperature and humidity are very high, this phenomenon would happen. This is caused by the room air is indoor temperature and humidity will fall down, the mist will die away. |
Creaking noise can be heard when start or stopping the unit![]() | ● This is caused by the deformation of plastic due to the changes of temperature. |

Troubleshooting
