Frequently Asked Questions - ARC-12D Snö

How do I clean the air filter on my Snö ARC-12D?

Turn off the unit and unplug it. Remove the filter cover, take out the mesh filter, and wash it with lukewarm water. Let it dry completely before reinstalling. Clean every 2 weeks for optimal performance.

Can I use the air conditioner without the exhaust hose?

No, the exhaust hose is required to vent hot air outside. Using it without the hose will cause inefficient cooling and may damage the unit.

Why is my Snö ARC-12D not cooling properly?

Check if the filter is dirty, ensure the exhaust hose is not blocked or kinked, and verify that the window kit is properly sealed. Also, make sure the unit is in Cool Mode and the set temperature is lower than room temperature.

How do I set the timer on the ARC-12D?

Press the Timer button on the remote or control panel. Use the +/- buttons to set the desired hours (1-24). The unit will automatically turn on or off after the set time, depending on the mode selected.

What does the self-evaporative system mean?

The self-evaporative system reuses moisture collected from the air to cool the condenser coil, reducing the need to drain water. In high humidity, you may need to drain manually using the drain plug.

Can I use an extension cord with my Snö air conditioner?

It is not recommended. Use a dedicated outlet with the correct voltage (115V). If an extension cord is necessary, use a heavy-duty cord rated for at least 15 amps and keep it as short as possible.

How do I switch between cooling, fan, and dehumidify modes?

Press the Mode button repeatedly to cycle through Cool, Fan, Dehumidify, and Auto modes. The selected mode will be indicated on the display.

What is the recommended maintenance for the ARC-12D?

Clean the filter every 2 weeks, check the exhaust hose for blockages, and wipe the exterior with a damp cloth. At the end of the season, drain any remaining water and store the unit in a dry place.

Why does my air conditioner display 'Full' or 'E0' error?

The 'Full' indicator means the water tank is full. Drain the water via the drain plug. 'E0' may indicate a sensor error; try unplugging for 10 minutes and restarting. If persists, contact customer service.

Is the Snö ARC-12D suitable for large rooms?

With a cooling capacity of 12000 BTU/h, it is suitable for rooms up to 450-550 sq ft. For best results, keep doors and windows closed and ensure proper exhaust venting.

Operation

Setting The Fan Speed

Press the SPEED button to choose the fan speed you require, high or low. The indicator of high or low fan will light up at the same time.

If the unit is in AUTO mode, it will select the fan speed automatically according to the ambient temperature (the related indicators, cool, fan or heat will light up), at this time the fan speed switch is invalid.

Setting the Timer

Press the TIMER button to set the operating hours you desire (1 to 12 hours, the timer indicator will light up). When the set time has elapsed, the machine will turn off

automatically. The display window will show the hour(s) you set as you press the TIMER button. If the timer button is not pressed, the unit will work continuously.

By pressing the timer button but without turning on the unit, you can PRE-SET the time for the machine to work. For example, if you press the timer to '2', the unit will come on automatically after 2 hours.

All the above functions can also be performed with the supplied remote control. This remote control requires 2 AAA batteries to operate.

Regulating the airflow direction

Turn the roller on the air vent to control the airflow direction from the vertical louvres.

IMPORTANT!

• The compressor will start approximately 3 minutes after the unit is turned on (this will help prolong the life of the compressor). After switching the unit off, please wait at least 3 minutes before turning the unit back on.
• The cooling system will switch off if the room temperature is lower than set. The fan, however, keeps working at the set level. If the ambient temperature rises above the chosen temperature +5^ , the cooling will resume.
• In heating mode, the compressor will switch off if the room temperature is HIGHER than the one set (the fan keeps working at the set level). When the room temperature drops 5^ below the chosen temperature, heating will resume.
• This machine is equipped with an ANTI-FROST function. Sometimes, while using the heating function during low temperatures, the heating will stop for a while to melt the internal frost. When this occurs, wait for heating to resume.
• As you switch on the heating, the fan will stop for 15-20 seconds prior to the unit starting.

Setting Mode/Function

Press the MODE button to select the required working mode: Automatic, Cooling, Fan or Heating (Heating is only available for ARC-12H). The green indicator illustrating your selected mode lights up. It is recommended to select Cooling or Heating mode and set your desired temperature, as the Auto mode has a preset temperature (please see below) that cannot be changed.

The indicators of the functions in progress come on at the same time, e.g. Cool and Lo = Cooling mode with Low fan speed.

Auto Mode

When this mode is selected, the unit is preset to the following temperature settings and unit will only start to:

- Cool when room temperature is higher than 75°F - Heat when room temperature is lower than 68°F (ARC-12H only)

If room temperature is between 68°F and 75°F, unit will stay in Fan mode. Again, when in Auto Mode, the temperature settings cannot be changed.

Setting the Temperature in Cooling or Heating Mode

The display window's default is to display the ambient room temperature. The green indicator light under RT is on. (RT = Room Temperature)

To set your desired temperature, press the Temperature up or down buttons (ranging from 62°F to 90°F). Each press will increase or decrease your set temperature by 1°F. When pressing the temperature up or down buttons, the window will change to display your set temperature. At this time, the green indicator will light under ST (Set Temperature). Once the temperature up or down buttons is released, the window will return to displaying the ambient temperature after a second.
Note: When unit is in the following modes: Auto, Cool, or Heat - the compressor will cool/heat the room to reach the set temperature. Once the ambient temperature has reached the set temperature, the compressor will stop and unit will run in Fan mode. To conserve energy, the compressor will not start immediately after a couple degrees increase or decrease, but will wait for a 5°F allowance. For example:
In Cooling Mode with a set temperature of 70°F
When compressor first stops after reaching 70°F, unit will auto-switch to Fan.
Compressor will start cooling again when ambient temperature increases to 75°F or above.
In Hearing Mode with a set temperature of 72°F
When compressor first stops after reaching 72°F, unit will auto-switch to Fan.
Compressor will start heating again when ambient temperature drops to 67°F or below.
In Auto Mode (with preset temperature of 68^ F for heat and 75^ F for cool)
Compressor will start cooling again when ambient temperature reaches above 80^ F or will start heating when ambient temperature drops below 63^ F.

Drainage

During the process of cooling, some water will be extracted from the air into the unit. Most of this water is used to cool the unit and make it run more efficiently. This is a feature not found in most Portable Air Conditioners. If the unit is operated in VERY HUMID air, water will collect in the container inside the unit. If the water container is full, the compressor will stop, but the fan will continue to circulate the air. The POWER indicator will blink to inform you to empty the internal container. To make the cooling function work again, please empty the water by one of the following methods:

By the Draining into a Container

Use a Shallow Container or Dish

1. Turn off the unit
2. Position a flat container or dish under the drain hole. Do not allow the water to drip continuously into the container, as it might easily overflow.
3. Remove the drain knob & rubber plug from the drain hole. The condensed water will drain out automatically.
4. When the container is almost full, replace the rubber plug into the drain hole to stop the water. Empty the container.
5. Repeat steps 2, 3 & 4 until all the condensed water is emptied.
6. Once all the condensed water has been removed, replace the rubber plug into the drain hole firmly. The Full Water indicator should be off now.
7. Replace the drain knob.

By Water Tube (Continuous Drainage)

1. Remove the drain knob and rubber plug and keep them for future use.
2. Connect a suitable water tube (of 3/4" internal diameter - supplied) to the water hole. The condensed water will drain out automatically.
3. If you want to extend the water tube you can connect it with another tube (outside diameter 3/4").

Special Caution for Heating Function!

While using the heating function, please note:
1. Install the exhaust pipe securely in order to exhaust the cool air to the outside (please see page 6).
2. Use the continuous drainage option as described above.
3. The warmer the outside air the more heat will be pumped into the room. Working range for heat pump function is 41^ F to 81^ F. When used in room temperatures outside this range, the unit may not function properly.
4. While using the heating function during low temperatures, sometimes the heating will stop for a while in order to melt the internal frost. When this occurs, just wait for heating to resume. This is normal for compressor operated devices.
