TOSOT Portable Air Conditioner User Manual

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

1. 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.
2. 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.
3. Some parts with sharp edges may cause injury, so gloves are highly recommended for unpacking and installing.
4. 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.
5. For a quick start video guide of installation, please contact Customer Support.
6. 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.

Installing Your AC

Here are the detailed instructions for installing the window panel into sliding sash or hung windows. For certain windows, such as a casement window, you will need to improvise several steps of the installation as each specific window will be different.

1. Cut the Foam seal B (adhesive type) to the proper length and attach it to your horizontal (or vertical) sliding window.
2. Attach the insect guard to the back side of the window panel. Push in to ensure that it fits securely. If you do not want to install the rain guard, skip to Step 4 below.
3. Optional: Install the rain guard over the insect guard to prevent rainwater from leaking into the exhaust hose. Insert the three projections on each rain guard into the holes in the insect guard. Side "A" should be at the top, as indicated in the diagram below.
4. Insert the insect guard firmly to ensure that the four projections fit into the holes of the window panel. Make sure that Side A is on the top.
5. Slide the Exhaust Cover into the grooves of the Window Panel.
6. 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.
   Window panel (cut if necessary): 28.3inch Adjustment panel: 18.3inch Extension panel: 18.3inch Exhaust cover: 4.8inch, 10inch

   You can slide the exhaust cover to cover the hole of the window panel when the exhaust hose is removed.

   Hung Window: Window width Max 62inch / Min 9.1inch Sliding Slash Window: Window width Max 62inch / Min 9.1inch
7. Find the adjustment panel (with two grooves on each end), and a Fixed Clip and Mounting Plate.
8. Insert the fixed clip into the groove of the adjustment panel.
9. 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.
10. Screw the mounting plate into the fixed clip to secure the panels together once it is at the length of your window.
11. 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.
12. Insert the window panel into the window sill and close the window securely against the Window panel.
13. Stuff Foam Seal A (non adhesive) between the glass and the window to prevent air and insects from getting into the room.
14. Optional: Attach a bracket to the window frame with a screw to prevent any gaps from opening up.

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 onto the exhaust hose.
2. Insert the Joint into the groove on the back of the unit and extend the exhaust hose. The side with "TOP" is upwards.
3. Attach the Rear clip to the window panel.

Tips: 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.

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

The internal pan can hold about 0.5L of water. 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.
3. Plug back the rubber plug to the port. The unit will resume operation in 3 minutes.

Note: You can also insert a drain hose (included) to the port to aid drainage. Here, you will need to insert the hose to the port first before operation and secure it with a pipe clip. Then, attach it to the drainage pipe clip at the back of the machine. When draining, remove the hose from the clip and water will flow from the pipe.

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.
2. Screw the drain hose adapter into the spout by twisting clockwise and attach the drain hose to the drain adapter.

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.

Direction of wire hook is downward

Cleaning and Maintenance

To avoid electric shock, turn off the air conditioner and disconnect from power before cleaning. Do not wash or douse the air conditioner with water. Never use abrasive or flammable solvents to clean the air conditioner.

Cleaning the outer case

Wipe with a soft cloth soaked in warm water and a mild detergent, if needed.

Cleaning the exhaust hose

Remove the exhaust hose from the air conditioner and clean with a soft cloth soaked in warm water. Let dry completely before reinstalling.

Cleaning the filter

1. Remove the filter: Locate the filter and remove it from the air conditioner. You may need to move the filter around to loosen.
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 of the 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.
