12V 12000BTU Air Conditioner Mini Split A/C For Semi Trucks Bus RV Caravan Vans

Description

Outdoor unit
The outdoor unit adopts an integrated electric compressor, which greatly improves the refrigeration efficiency of the air conditioner and reduces the failure rate of the air conditioner. Compared with the traditional old-fashioned compressor, the integrated compressor has been greatly improved.
Indoor unit
The indoor unit adopts an intelligent numerical panel. When the air conditioner fails, you can see the fault code of the panel to confirm where the fault is. The five hole rotary air outlet can adjust the air outlet angle at will for low decibel operation.
Remote control
The remote control has a variety of modes to choose from. The cooling mode can be adjusted as required. The wind speed of the outdoor unit fan can also be controlled by the remote controller.

matters needing attention
The starting current of 12V air conditioner shall reach 75A. Before purchasing, please confirm whether the battery meets the requirements.
Before adding refrigerant, vacuum treatment (15-20 minutes) is required, and then add refrigerant.
There is no refrigerant inside the air conditioner, so R134a/600g should be added. Pressure gauge value: low pressure 35psi, high pressure 140-180psi.
Installation steps
Install the external machine:
remove the casing, mark the drilling position, use an 8mm drill to drill holes, use 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 fix the external machine to the car .
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 wrong installation.Then wrap it in black cotton wrap.
Install the indoor unit:
first install the wooden board to the indoor wall, and then install the evaporator on the wooden board.
Install high and 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.
Install 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:
Connect the power cord to the battery, pay attention to the positive and negative poles of the battery, do not connect them wrongly, + positive / - negative. It is forbidden to connect it to the power-off switch and the power switch.
Turn on the air conditioner:
Drive the air conditioner to see if it works 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.
