Frequently Asked Questions - AC-S7 AKIRA

How do I install the AC-S7 portable air conditioner?

Place the unit near a window and install the included window sealing plate. Connect the exhaust hose to the unit and the window kit. Ensure the hose is straight and not bent. Plug in the unit and select a mode.

Do I need to empty a water bucket?

No, the AC-S7 features auto evaporation technology that evaporates most of the condensation. In high humidity, the unit may need occasional draining via the drain plug.

How often should I clean the air filter?

Clean the washable filter every two weeks for optimal performance. Remove the filter, wash with mild soap and water, dry completely, and reinstall.

Can I use the AC-S7 in a room without a window?

The unit requires venting to the outside. It can be vented through a window, sliding door, or a wall hole using the included kit. Without external venting, it will not cool effectively.

What is the cooling coverage area?

The AC-S7 is suitable for rooms up to 150-200 sq ft (approximately 14-19 m²) depending on insulation and ceiling height.

Does the remote control require batteries?

Yes, the remote control uses two AAA batteries (not included). Point the remote at the unit and press the desired button.

Why is the unit not cooling as expected?

Check that the filter is clean, the exhaust hose is properly installed and not blocked, the window kit is sealed, and the room is not too large. Also ensure the unit is in Cool mode with a set temperature below room temperature.

How loud is the AC-S7 during operation?

The noise level is approximately 52 dB(A) on high speed, which is similar to a quiet conversation. Use Sleep mode for quieter operation at night.

Can I use an extension cord?

It is recommended to plug the unit directly into a grounded wall outlet. If an extension cord is necessary, use a heavy-duty cord rated for the unit's power (minimum 10 amps) and keep it as short as possible.

How do I change the mode or temperature?

Press the Mode button on the control panel or remote to cycle through Cool, Fan, Dehumidify, and Sleep. Use the + and - buttons to adjust the temperature (in Cool mode) or fan speed.

1. AIR PURGING (INSTALLATION)

• Required tools: hexagonal wrench, adjustable wrench, torque wrenches, wrench to hold the joints, and gas leak detector.
• The additional gas for air purging has been charged in the outdoor unit. However, if the flare connections have not been done correctly and gas leaks, a gas cylinder and the charge set will be needed.
• The air in the indoor unit and in the piping must be purged. If air remains in the refrigerant pipes, it will affect the compressor, reduce the cooling and heating capacity, and could lead to a malfunction.

    D --> E["Outdoor unit"]
    B --> F["3-way valve"]
    D --> G["Close"]

• Be sure to use a torque wrench to tighten the service port cap (after using the service port), so that it prevents the gas leakage from the refrigeration cycle.
  ● Caution: Do not leak the gas in the air during air purging.
  ● Air purging procedure

Recheck the piping connections.

Open the valve spindle of the 2-way valve counter-clockwise proximately 90°, wait 10 seconds, and then set it to closed position. Be sure to use a hexagonal wrench to operate the spindle.

Check the flare connections for refrigerant gas leakage.

Purge the air from the system. Set the 2-way valve to the open position and remove the cap from the 3-way valve's service port. Using the hexagonal wrench to press the valve core pin, discharge for three seconds and then wait for one minute. Repeat this three times.

Use torque wrench to tighten the service port cap to a torque of 1.8kg.cm.

Set the 3-way valve to the back seat.

Mount the valve caps to the 2-way and 3-way valves.

Check for gas leakage. At this time, especially check for gas leakage from the 2-way and 3-way valve's caps, and from the service port cap.

● Caution: If gas leakage is discovered, take the following measures.

If the gas leakage stops when the piping connections are tightened further, continue working.

If the gas leakage does not stop when the piping connections are tightened, repair the location of the leakage, discharge all of the gas through the service port, and then recharge with the specified amount of gas from a gas cylinder.

  Be sure to use a hexagonal wrench to operate the valve spindle.
• Operate the unit for 10\~15 minutes.
• Stop operation and wait for 3 minutes, then connect the charge set to the service port of the3-way valve.
  Connect the charge hose with the push pin to the service port.
  ● Air purging of the charge hose
  Open the low-pressure valve on the charge set slightly to purge air from the charge hose.
• Set the 2-way valve to the closed position.
• Operate the air conditioner at the cooling cycle and stop it when the gauge indicates 1kg/cm^2 .g.
• Immediately set the 3-way valve to the closed position.
  Do this quickly so that the gauge ends up indicating 3 to 5kg/cm^2 .g.
• Disconnect the charge set, and amount the 2-way and 3-way valve's caps and the service port cap.
  Use torque wrench to tighten the service port cap to a torque of 1.8 kg.m.
  Be sure to check for gas leakage.

3. RE-AIR PURGING FOR RE-INSTALLATION

• Confirm that both the 2-way valve and the 3-way valve are set to the closed position.
• Connect the charge set and a gas cylinder to the service port of the 3-way valve.
  Leave the valve on the gas cylinder closed.

Air purging

Open the valves on the gas cylinder and the charge set. Purge the air by loosening the flare nut on the 2-way valve approximately 45° for 3 seconds, then

closing it for 1 minute. Repeat 3 times.

After purging the air, use a torque wrench to tighten the flare nut on the 2-way valve.

• Open the valve (Low side) on the charge set and discharged the refrigerant until the gauge indicates 0kg/cm^2 .
  If there is no air in the refrigerant cycle (the pressure when the air conditioner is not running is higher than 1 kg/cm^2 · g ), discharge the refrigerant until the gauge indicates 0.5 to 1 kg/cm^2 · g . If this is the case, it will not be necessary to apply an evacuation.
  Discharge the refrigerant gradually. If it is discharged too suddenly, the refrigeration oil will also be discharged.

5. EVACUATION (ALL AMOUNT OF REFRIGERANT LEAKED)

• Connect the vacuum pump to the charge set's center hose.
  ● Evacuating for approximately one hour.
  Confirm that the gauge needle has moved toward -76cmHg (vacuum of 4 mmHg or less)

• Close the valve (Low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump).

• Disconnect the charge hose from the vacuum pump.
  If the vacuum pump oil becomes dirty or depleted, replenish as needed.

6. GAS CHARGING (AFTER EVACUATION)

• Connect the charge hose to the charging cylinder.
  Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder.
  If you are using a gas cylinder, also use a scale and level the cylinder so that the system can be charged with liquid.
  ● Purge the air from the charge hose.
  Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air.(Be careful of the liquid refrigerant).The procedure is the same if using a gas cylinder.
• Open the valve (Low side on the charge set) and charge the system with liquid

refrigerant.

If the system can not be charged with the specified amount of refrigerant, it can be charged with a little at a time (approximately 150g each time) while operating the air conditioner in the cooling cycle. However, one time is not sufficient, wait approximately 1 minute and then repeat the procedure (pumping down pin).
This is different from previous procedures. Because you are charging with liquid refrigerant from the gas side, absolutely do not attempt to charge with larger amounts of liquid refrigerant while operating the air conditioner.
- Immediately disconnect the charge hose from the 3-way valve's service port.
Stopping partway will allow the gas to be discharged.
If the system has been charged with liquid refrigerant while operating the air conditioner before disconnecting the hose.
● Mount the valve caps and service port cap.
Use torque wrench to tighten the service port cap to a torque of 1.8kg.m.
Be sure to check for gas leakage.

CHAPTER 9: TROUBLESHOOTING

• In order to diagnose malfunctions, make sure that there is no electrical problems before inspecting the refrigeration cycle. Such problems include insufficient thermal insulation, problem with the power supply, malfunction of a compressor and indoor or outdoor fan motor.
• The normal indoor outlet air temperature and pressure of the refrigeration cycle depends upon various conditions. The standard values for them are shown in the following table.

Normal Pressure and Outlet Air Temperature

Gas Pressure	MPa(kg/cm2.g)	Outlet Air Temperature
Cooling Mode	0.4~0.6(4~6)	12~16

*Condition: Indoor fan speed: High ; Outdoor DB temperature:35
