TOSOT Portable Air Conditioner

Welcome to the TOSOT Direct Family!

We're extremely happy to welcome you as a new member of our family! Please read the tips below before using your product for the first time.

Tips for First-Time Use

• The portable air conditioner is a heavy object, which needs two or more people to lift and install. Failure to do so could result in injury or other accidents.
• Allow the unit to sit upright for at least 3-4 hours before powering on. Shipping carriers may set the unit on its side, which causes the refrigerant to pool in certain areas. Standing the unit upright for 3-4 hours allows the refrigerant to move freely within the coils.
• Some parts with sharp edges may cause injury, so gloves are highly recommended for unpacking and installing.
• Run the unit continuously for 24 hours after letting the unit stand upright for 3-4 hours. This allows the unit to work out any "kinks" that may have resulted during shipping from our factory to your doorstep.
• For a quick start video guide of installation, please contact Customer Support.
• If you have any problems with your product, please send us an email before submitting a return request, as there might be a simple solution for your issue.

Diagram Description: Shows the exhaust cover sliding into the grooves of the window panel.

5. Installing the Window Panel(s)

This window installation kit comes with 3 panels to adjust to your exact window size. You may not need to use all three panels. To begin, please refer to the guide below:

• If your window is less than 28 inches long, you only need the window panel. You may need to saw off part of the window panel if your window is smaller than the window panel length.
• If your window is 28 to 46 inches long, you will need the window and adjustment panel. You will not need the extension panel.
• If your window is 46 to 62 inches long, you will need all three panels.
• Last, if your window is longer than 62 inches, you will need all three panels and then need to improvise to fill the remaining gap.

Diagram Description (Panels): Shows dimensions for:

1. Window panel (cut if necessary): 28.3 inches long, 5 inches high.
2. Adjustment panel: 18.3 inches long, 4.8 inches high.
3. Extension panel: 18.3 inches long, 5 inches high.
4. Exhaust cover: 10 inches long, 4.8 inches high. (Note: You can slide the exhaust cover to cover the hole of the window panel when the exhaust hose is removed.)

Diagram Description (Window Configurations):

• Hung Window: Shows panels 1, 2, 3 arranged, with window width measurements (Max 62 inches / Min 9.1 inches).
• Sliding Sash Window: Shows panels 1, 2, 3 arranged, with window width measurements (Max 62 inches / Min 9.1 inches).

Panel Assembly Steps:

a. Find the adjustment panel (with two grooves on each end), and a Fixed Clip and Mounting Plate.

b. Insert the fixed clip into the groove of the adjustment panel.

c. Slide the fixed clip into the groove of the window panel and slide the fixed clip until there is no gap between the two panels.

d. Screw the mounting plate into the fixed clip to secure the panels together once it is at the length of your window.

Diagram Description: Shows close-ups of the fixed clip and mounting plate securing the panels.

e. If needed, follow the above steps to connect the other side of the adjustment panel to the extension panel. The total length of the panels will reach 62 inches. If your window is longer than 62 inches, you will need to improvise to fill in the gap.

6. Insert the window panel into the window sill and close the window securely against the Window panel.

Diagram Description: Shows the window panel fitted into the window sill, and the window closed against it.

7. Stuff Foam Seal A (non adhesive) between the glass and the window to prevent air and insects from getting into the room.

8. Optional: Attach a bracket to the window frame with a screw to prevent any gaps from opening up.

Diagram Description: Shows a bracket being attached to the window frame.

Installing the Exhaust Hose

Please note that the exhaust hose is REQUIRED to use for this portable air conditioner. This TOSOT portable air conditioner (like all air conditioners) must produce heat as a byproduct of producing cool air. If you don't connect the exhaust hose, your unit will exhaust this hot air into the room you are trying to cool. That won't work very well.

1. Twist the Joint and Rear Clip clockwise [clockwise-arrow] onto the exhaust hose.

Diagram Description: Shows the Joint and Rear Clip being twisted onto the ends of the exhaust hose.

2. Insert the Joint into the groove on the back of the unit and extend the exhaust hose.

Diagram Description: Shows a close-up of the "clasp" and "groove" for inserting the Joint into the unit, and the exhaust hose extending.

3. Attach the Rear clip to the window panel.

Diagram Description: Shows the Rear Clip secured to the window panel.

Tips for Exhaust Hose Configuration

In order to improve the cooling efficiency of your air conditioner, the exhaust hose should be as short and direct as possible. Our suggested configuration is shown below.

Diagram Description: Shows two configurations:

• Correct: A short, direct exhaust hose setup, with text "about 24 inches".
• Wrong: A long, convoluted exhaust hose setup, with text "under 51 inches" (implying it should be longer than this, or that this is a bad length). The implication is that shorter and more direct is better.

Removing Collected Water

TOSOT portable air conditioner comes with an auto-evaporation system. The unit automatically evaporates the condensation. There is no need to empty the water except in humid conditions.

Manual Drainage

When it is filled with water, an alarm will beep 8 times and the display panel will show an H8 malfunction code to remind you to drain the water. For manual drainage, you will need to:

1. Move the unit to a suitable place for discharging water. Please keep the unit horizontal so water does not spill.
2. Remove the rubber plug from the drainage port and the collected water will drain.

Diagram Description: Shows the drainage port on the unit.

Continuous Drainage

Water can be drained into a floor drain by attaching a drain hose (included) to the continuous drain port.

1. Remove the continuous drain cap by turning it counter clockwise [counter-clockwise-arrow], then remove the rubber plug from the spout.

Diagram Description: Shows the continuous drain cap being removed and the rubber plug being taken out.

2. Insert the drainage hose into the drain connector.

Note: When using the continuous drainage option, make sure that the air conditioner is located on a flat, level surface and that the drain hose is directed downwards and clear of any obstructions. Placing the air conditioner on an uneven surface may result in the chassis filling with water until the H8 malfunction code is displayed. If this occurs, manually empty the water in the chassis then recheck the air conditioner location and hose connection.

Installing the Power Cord Hooks

Attach the two power cord hooks on the back of the unit using the included screws and wrap the power cord around the power cord hooks when not in use.

Diagram Description: Shows power cord hooks being attached to the back of the unit with screws, and the power cord being wrapped around them.

Cleaning and Maintenance

Precautions

• Before cleaning the air conditioner, please turn off the unit and disconnect power. Otherwise, it may cause electric shock.
• Do not wash the air conditioner with water. Otherwise, it may cause electric shock.
• Do not use volatile liquid (such as thinner or gas) to clean the air conditioner. Otherwise, it may damage the appearance of the air conditioner.
• Do not use liquid or corrosive detergent, clean the appliance and do not splash water or other liquid onto it, otherwise, it may damage the plastic components, even causing electric shock.

Cleaning outer case

If there's dust on the surface of the outer case, please use a soft cloth to wipe it. You might need to use mild detergent to do the cleaning.

Cleaning the filter

1. Remove the filter

Press the clasp at the back of the unit and then remove the filter. You may need to move the filter around to loosen.

Diagram Description: Shows how to release the clasp and remove the filter from the unit.

2. Clean the filter

After removing, use the dust attachment of your vacuum to suck up any dirt or warm water mixed with a mild detergent. A soft bristle brush may help remove some dirt if needed.

3. Reinstall the filter

After the filter has dried completely, reinstall back into the air conditioner.

Notes:

• Clean the filter at least every three months.
• Do not touch the metal fins in the air conditioner after removing the filter as they may cause personal injury.
• Do not attempt to dry the filter with a hairdryer or other heating elements as this may deform or ignite the filter.
• Do not operate the air conditioner if the air filter is missing.
