The External Machine should be installed as follows: Remove the casing, mark the drilling position, use an 8mm drill to create holes, employ a riveting tool to fix the rivet nut at the drilling point, install shock pads and sleeves at the holes of the external machine, and then secure the external machine to the car.

Next, install the Expansion Valve: Remove the iron sheet at the position of the expansion valve of the evaporator, and fix the expansion valve to the evaporator. The two black screws correspond to the two holes, so there is no need to worry about incorrect installation. Then, wrap it in black cotton wrap.

For the Indoor Unit installation: First, install the wooden board to the indoor wall, and then mount the evaporator on the wooden board.

Regarding the High & Low Pressure Pipelines: First, open a (50mm) hole in the car, and then install the rubber cover with three holes. The thick pipe is the low pressure pipe and is connected to the compressor. The thin tube is a high pressure tube and is connected to the condenser. Then, connect the other end of the high and low pressure pipes to the holes corresponding to the expansion valve of the indoor unit, use long black screws and iron sheets to clamp the aluminum joints, and tighten the screws.

For the Connection Line: Connect the connection lines of the internal and external units, plug the power cord plugs into each other, and connect the drain pipe of the evaporator.

Vacuuming/Adding Refrigerant: It needs to be vacuumed for 15-20 minutes, and then add refrigerant R134a/600g. The refrigerant can be added according to the pressure value. Generally, after the R134a refrigerant is injected into the air conditioning system, the pressure at the low pressure port is 35psi, and the pressure at the high pressure port is 140-180psi.

Connect the Power Cord to the Battery: Connect the power cord to the battery, pay attention to the positive and negative poles of the battery, avoid connecting them conversely, + positive / - negative. It is forbidden to connect it to the power-off switch and the power switch.

Finally, Test to see if it works: Start the Air Conditioner to see if it functions properly. If the current is insufficient, the refrigerant is too much or not enough, the control panel will display a code, which can quickly troubleshoot.
