Product Q&A

Q:Does this unit need to be vented outside?

Yes, there must be a heat emission hole in your system. You can use flexible tubes to connect the air conditioner unit to vent the heat.

Q:How do I connect the wiring?

All wires are ready before shipping. Users only need to do 3 steps: 1. Connect to the DC power supply. 2. Connect the drive board to the compressor. 3. Connect to your system's on/off switch.

Q:Do I need to recharge the refrigerant?

No, all units are fully charged with oil and refrigerant before shipping. If maintenance is needed later, there is a valve for refrigerant refill.

Q:How is condensate water handled?

There is a drain for condensate water. You can collect the condensed water via a tube into a condensed collection tank if you wish to reuse it.

Q:How can I control the compressor speed?

There are 3 ways: 1. Potentiometer speed control (included). 2. PWM Speed Control. 3. UART communication port. The most common method is via the included potentiometer.
