Safety Guidelines
Do no use if he elec ronics or provided ba ery are submerged
in wa er. Dry ou comple ely and es for func ionali y in a
con rolled environmen if any par of he Chilles ’s elec ronics or
ba ery are submerged in wa er.
Verify power source voltage and amperage before using. Change
battery protection level as needed depending on power source.
Do not place electronics in the Chillest when in operation.
Do not tilt past 45 degrees during transportation or 15 degrees
during operation. If the Chillest falls over or ips during
transportation or operation, turn off immediately and allow to
rest for at least 12hrs before turning back on. Liquid refrigerant
may have gotten to the compressor, and you must allow it to
evaporate before turning back on. The compressor is designed
for evaporated refrigerant only, liquid refrigerant can cause
immediate and permanent compressor damage.
Do not operate the Chillest next to a heat source (re, stove or
heater), avoid operating the Chillest in direct sunlight if possible.
The cooler areas of he Chilles can hold wa er. To drain any
wa er from he Chilles , use he drainage plug in he bo om of
he larger side of he uni . DO NOT POUR WATER OUT OF THE
CHILLEST FROM THE LID, his will po en ially allow liquid
refrigeran o reach he compressor and you will need o wai 12
hrs before using he chill again while you wai for he refrigeran
o fully evapora e. Use a cup or owel o remove buil up wa er
from he smaller cooler sec ion if needed.

We recommend you clean the Chillest’s interior before rst use.
Use a damp cloth with mild soapy water.
Never use harsh cleaners with the GoSun Chillest. Only use a
damp cloth with mild soapy water. Do not use a hose to clean
the outside of the Chillest as water may get into the compressor
and electronics section of the unit.
Clean and dry the inside of the Chillest after each use. If storing
for more than 24hrs, we recommend you partially open the lid
during storage.
The GoSun Chillest is not designed as a seat, do not stand or sit
on the Chillest.
Ensure the Chillest has proper ventilation to the compressor
chamber. Leave space to the front, back, and side of the Chillest
as shown in the diagram below ▪ Front: 4” (10cm) ▪ Back: 8”

3.4 Source Battery Protection Settings
By default the GoSun Chillest is set to protect the Included lithium
battery-based Power bank This setting will not protect a 12V lead
acid battery in your car Because of the differences in battery
voltages, the GoSun Chillest has three different battery protection
settings to help ensure that you can always protect your power
source from over-discharge To change this setting, when the
Chillest is powered on and running, hold the settings button until
you see the display ash (L, M, or H) Then press the setting
button again to change the setting for the battery being used
L: Protection for a standard 12V Lithium-ion battery.
Low voltage cutoff: 9.0V DC (12V) or 18V DC (24V 
R eco nn ect Voltage: 10.9V DC (12V) or 21.8V DC (24V)

M: Protection for a 2V lead acid battery when being used
solely for portable power. (Also a good setting for 12V
Lithium Iron Phosphate batteries)
Low voltage cutoff: 10.1V DC (12V) or 20.2V DC (24V)
Reconnect Voltage: 11.4V DC (12V) or 22.8V DC (24V)
H: Protection for a 2V car batter
Low voltage cutoff: 11.1V DC (12V) or 22.2V DC (24V)
Reconnect Voltage: 12.4V DC (12V) or 24.8V DC (24V)
3.5 Bungee Tie-Downs
There are four tie-down bars at the four corners of the chillest.
These are good locations to use with the provided bungee cords
to hold items on top of the Chillest
Troubleshooting
The Chillest is not cooling down
Check the power cord connection
Check that your power source is fully charged.
Make sure the power button was pressed and the indicator states
the Chillest is running.
Check the F use in the D C power cord ( if applicable).
Check the fuse inside the compressor / electronics section.
The compressor may be in delay start mode to protect the
compressor , allow 5 min before continuing to troubleshoot
F ood inside is fro z en

The Chillest makes a sound like water owing or bubbling.
This is normal it is the refrigerant circulating within the unit.
The Chillest makes a metallic sound when going over a
bump or transporting the unit
This is normal the compressor is suspended by springs within the
sealed chamber and larger bumps can allow the compressor to
touch the outer shell of the chamber.

Defrosting
After prolonged use, your GoSun Chillest may start to accumulate
frost on the inside. If the frost gets more than 1/4” (6mm) thick it is
recommended to defrost the Chillest to maximi e energy
efciency.
To change the GoSun Chillest’s Advanced Settings, hold the setting
button when the GoSun Chillest is powered off, but still connected to
power. E1 will ash on the screen, press the settings button to cycle
through from E1 through EE. To change a setting press the up or down
buttons.
