Product Q&A

Q:Does this unit require venting outside the cabinet?

Yes, a heat emission outlet is necessary. Flexible tubes can be used to connect the air conditioner unit to the outside.

Q:How do I connect the wiring for the cooling system?

All wiring is pre-prepared. Simply connect to the DC power supply, link the drive board to the compressor, and connect to your system's on/off switch.

Q:Do I need to recharge the refrigerant?

No, units are pre-charged with oil and refrigerant. A dedicated valve is available for future maintenance if a refill is necessary.

Q:Is a controller device included?

The unit does not include an On & Off switch. You must wire a personalized switch, but the drive board is included for integration.

Q:How should condensate water be managed?

Use the strategically positioned drain to collect condensed water via a tube into a consolidated collection tank for disposal or reuse.
