Frequently Asked Questions - SPTNH12A3 Infiniton
How do I install the exhaust hose?
Install the exhaust hose by connecting it to the back of the unit and extending it to an open window or vent. The hose should be kept as short and straight as possible to ensure efficient cooling. Use the provided window sealing plate to secure the gap.
How often should I clean the air filter?
Clean the air filter every two weeks to maintain optimal airflow and cooling performance. Remove the filter, wash it with warm water and mild detergent, let it dry completely, and then reinstall it. A dirty filter reduces efficiency and can cause frost buildup.
What should I do if water accumulates in the unit?
The SPTNH12A3 can produce condensation. If the internal water tank fills up, the unit may stop and display an error code. You can drain the water manually by removing the drain plug or attach a continuous drain hose to a floor drain. In dehumidifying mode, condensation is more frequent.
Does the SPTNH12A3 have a heating function?
No, the SPTNH12A3 is a cooling-only air conditioner. It provides cooling, dehumidifying, and fan modes, but does not have a heat pump or electric heater. However, it can be used as a fan for air circulation in the winter.
How do I use the timer function?
Press the Timer button on the remote or control panel. Use the +/- buttons to set the desired time (1-24 hours). You can set the unit to turn on or off automatically. The timer indicator will show the selected time, and the unit will operate accordingly.
What is the recommended room size for this air conditioner?
With a cooling capacity of 12000 BTU/h, the SPTNH12A3 is suitable for rooms up to 25-30 m² (270-320 sq ft), depending on insulation and sunlight exposure. For best results, close doors and windows to prevent cool air from escaping.
How can I reduce the noise level?
Place the unit on a flat, stable surface and ensure there is no vibration. Keep the exhaust hose properly connected to prevent rattling. You can use the fan-only mode at night for quieter operation, or activate the sleep mode if available.
What type of refrigerant does it use, and is it environmentally friendly?
The unit uses R290 (propane), a natural refrigerant with zero ozone depletion potential and a very low global warming potential. It is eco-friendly but highly flammable, so maintenance and repairs must be carried out by certified technicians.
Can I control the unit without the remote?
Yes, the unit has a touch control panel on the front display. You can manage power, mode, temperature, fan speed, and timer directly on the unit. The remote is more convenient but not mandatory.
What maintenance is required before seasonal storage?
Before storing, drain all condensation from the tank and hoses. Clean the air filter thoroughly and dry it. If possible, run the unit in fan mode for a few hours to dry the internal components. Clean the exterior and store the unit in a dry, dust-free place with the power cord secured.
