please read this user manual in its entirety.
MO DEL NUMBER
GPC08ASB-A6NNA1A
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.
Keep the original packaging material including packing foam, carton and
printed material until you decide to keep the unit. If you need to return the
unit, having all of the original packaging material will make it much easier.
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. Run the unit continuously for 24 hours after letting the unit stand upright for
3-4 hours. During this period, please pay more attention to any defective problem
of unit. To avoid any loss to your house, please make sure your unit has no any
defective problem caused by shipping damage such as leakage before using it
on the rugs or carpeting.
4. Some parts with sharp edges may cause injury, so gloves are highly recommended
for unpacking and installing.
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.

To reduce the risk of fire, electric shock, injury, or death to persons using or near
this appliance, please follow some basic safety precautions. These precautions
include, but are not limited to, the following:
● This appliance is not intended for use by any persons (including children) with
reduced or restricted physical, mental, or sensory capabilities, or lack of
experience and knowledge, unless under the direct supervision of a person
responsible for their safety.
● Please keep plastic bags and sheets out of the reach of children as they might
be mistakenly used for play. Packaging materials can become airtight chambers
and may pose a risk of suffocation if not disposed of properly.
● When installing or moving the appliance, be careful not to pinch, crush, or
damage the power cord.
● Never attempt to operate this appliance if it visibly damaged, malfunctioning,
disassembled or has missing or broken parts. This includes exposed wiring on
a damaged cord or electrical plugin. All repairs and servicing must be performed
by qualified service personnel. Use only authorized TOSOT factory OEM parts.
● Keep the product away from fire. Do not store or use flammable gases or
materials near the appliance.
● Do not use heating equipment near the appliance.
● In the event of a gas leak (propane gas, LP gas, etc.) do not operate this or any
other appliance. Open a window or door to ventilate the area immediately.
● Only use the appliance in an upright position. Make sure the angle of inclination
<10°. Always place the appliance on a stable, flat, level surface to prevent the
air conditioner from overturning.
02

authorized technical service center in order to avoid all risk.
● Do not damage, alter, excessively bend, twist, pull or heat the power cord.
● Do not cover the power cord with a rug or carpeting.
● Do not rest hot or heavy objects on the appliance and power cord.
● Always plug into a fixed 115V AC ground outlet.
● Specification of fuse on the main board: T3.15AH 250V; the maximum current
passing through the fuse can't be more than 3.15A.
● Never plug or unplug the appliance with wet hands.
● Push the power plug all the way into the wall outlet so that it will not loosen.
● Always grip the plug firmly and pull straight out from the outlet when taking it out.
● Never unplug the appliance by pulling on the power cord.
● Never use the appliance if the outlet is damaged or loose.

● Your air conditioner must be used in a properly grounded wall receptacle. If the
wall receptacle you intend to use is not adequately grounded or not protected by
a time-delay fuse or circuit breaker, have a qualified electrician install the proper
wall power receptacle before using this appliance.
● Be sure that the air conditioner is properly grounded. To minimize shock and fire
hazards, proper grounding is important. The power cord is equipped with a three-
prong grounding plug for protection against shock hazards.
● Do not run the air conditioner without the plastic shell in place. This could result
in mechanical damage within the air conditioner.

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.

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.
33
6. Insert the window panel into the window sill and close the window securely
against the Window panel.
7. Stuff Foam Seal A (non adhesive) between the glass and the window to prevent
air and insects from getting into the room.

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.
3) Attach the Rear clip to the window panel.

Removing Collected Water
TOSOT portable air conditioner comes with an auto-evaporation system. The unit
automatically evaporates condensation. There is no need to empty the water except
in humid conditions. It is recommended to use the bottom drainage port to drain
water during Cool mode.
When it is filled with water, 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.
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.

What is 3-Minute Compressor Protection?
All TOSOT Air Conditioners have a 3-Minute Compressor Protection feature to help
extend the lifespan of your unit. You may notice this happening when the unit is not
blowing cold air or you can’t hear the sound of the compressor. Below are some
situations where the 3-Minute Protection Mode will be activated:
A. Your unit just experienced a power outage. The compressor will restart again
after 3 minutes.
B. After you switch from the fan or dry mode to the cooling mode, there is a
3-minute delay before the compressor starts up.
C. If the unit is powered on, then powered off, then powered on again within a
3-minute period, there will be a 3-minute delay before the compressor starts
again.
D. If the ambient room temperature is lower than the set temperature on your
control panel, the compressor will power off for 3 minutes and restart once the
ambient room temperature rises above the set temperature again.
