This chapter provides instructions on how to use the TargetCool™ system, including instructions on
how to install the TargetCool™ consumables onto the TargetCool™ device, instructions on how to
operate TargetCool™, and instructions on how to remove consumables from the TargetCool™
device.
IMPORTANT
Before following any of the instructions in this chapter, it is strongly recommended that you familiarize
yourself with the entire User Manual, in particular Chapter 1 (Introduction), Chapter 2 (TargetCool™
Consumables), and Chapter 4 (More About the TargetCool™ device).
5.1 Instructions on How to Install the Consumables onto the
TargetCool™ Device
To install the TargetCool™ consumables onto the TargetCool™ device, you will need; (1) the
TargetCool™ device with the nozzle attached and fully fastened; and (2) a guard, an unused cartridge
filter (with two white O-rings attached), and an unused cartridge from the TargetCool™
Consumables Kit (sold separately).
NOTE
Before beginning these steps, ensure that the nozzle is fully fastened to the device. The nozzle is
fully fastened when the black O-ring between it and the device is no longer visible.
STEP 1: Select Nozzle and fully fasten it to
the TargetCool™
"Based on the mode (Cooling, Freezing, or
Boosting) you intend to use, select the
corresponding nozzle and attach it to the
TargetCool™ device."
- Cooling nozzle
- Boosting nozzle
- Freezing nozzle
STEP 2-1: (Only for Cooling nozzle) Attach
the guard onto the Guard Dock
Find the guard and the three magnets on the back
of the guard. The magnets are configured to attach
to the guard dock.
Position the guard and its magnets onto the guard
dock of the TargetCool™ device. Ensure when
handling the guard to avoid contacting the front
portion of the guard, which is configured to contact
the target area.
STEP 2-2: (Only for Boosting nozzle) Attach
the Boosting container to the Boosting
guard
After fastening the Boosting nozzle to the device
and attaching the Boosting guard to the guard
dock, insert the Boosting container into the
Boosting nozzle.

12
STEP 2-3: (Only for Freezing nozzle) Inspect
the Guard Dock
No guard is used in Freezing mode. So, inspect the
Guard Dock once again to make sure nothing is
attached.
STEP 3: Inspect the Cartridge Cavity
Find the cartridge cavity of the TargetCool™
device. Inspect the cartridge cavity and its
grooves and ensure that the area is clear of
any blockage (e.g., remnants of previously
used cartridge filters).
STEP 4: Insert the Cartridge Filter into the
Cartridge Cavity
Find the cartridge filter and the cartridge cavity. Pick
up the cartridge filter by its wings. Insert the
cartridge filter by its base first inside the cartridge
cavity.
NOTE
Make sure that both white plastic O-rings are
attached to the center of the filter. Hold the filter
by its wings and insert it fully into the cartridge
cavity. It is not uncommon for the smaller O-ring
to have become detached from the filter during
shipping or storage. If it is not present on the
filter, make sure to reattach it.
Position the cartridge filter so that the wings line up
and rest inside the corresponding two grooves on
the edge of the cartridge cavity. Push the cartridge
filter by the wings so that the base of the cartridge
filter rests firmly inside the cartridge cavity. Ensure
that the circular base of the cartridge filter is fully
inserted into the cartridge cavity.
STEP 5: Fasten a Cartridge into the
Cartridge Cavity
Find the cartridge and the cartridge cavity, which
should already have the cartridge filter fully inserted
per Step 5. Hold the TargetCool™ and position the
cartridge so that it is being inserted vertically from
below into the cartridge cavity. Insert the narrow,
threaded portion of the cartridge into the cartridge
cavity.
IMPORTANT
Throughout the cartridge fastening process,
ensure that the cartridge filter remains flush
inside the cartridge cavity. This may be difficult
to do when the device is pointing up. This can be
addressed by positioning a thumb under one of
the wings of the filter to maintain the cartridge
filter in the flush position while the device is
pointing upwards.
Begin fastening the cartridge into the cartridge cavity
by rotating the cartridge right and continuing to
rotate it until the cartridge is fully fastened. The
cartridge is fully fastened when you are no longer
able to comfortably rotate the cartridge.
IMPORTANT
As you fasten the cartridge into the cartridge
cavity, you may hear some gas noise coming from
the cartridge. Continue fastening the cartridge
and turning it to the right into the cartridge cavity
and the gas noise should stop. If you hear gas

5.2 Instructions on How to
Operate the TargetCool™
Device (Cooling Mode)
IMPORTANT
Before proceeding with this section:
• Ensure that the TargetCool™ device is
unplugged.
• Ensure that you have properly completed all
the steps in sections 5.1 and 5.2.
• Ensure that your environment conditions are
within a temperature range of 15°C to 30°C
(59°F to 86°F).
• Ensure that you are in a well-ventilated space.
STEP 1: Turn On the TargetCool™ Device
Find the power switch near the bottom of the
TargetCool™ device and toggle it to turn it ON. The
Status Light will show a flashing or “breathing” green
color.
IMPORTANT
If the TargetCool™ device does not turn on, it
may be that there is not enough charge in the
TargetCool™ device. Please turn off the device,
connect the USB-C charger to the charge port
and charge the device for at least half an hour
before attempting to turn the device on again. If
the device continues to not function, please
toggle the power switch OFF and contact
CoolHealth.
STEP 2: Inspect the LCD Display
Find the LCD Display and confirm it is showing the
screen in the above image. This is the SET UP
SCREEN and the Status Light will show a solid green
color.
NOTE
OPTIONAL: By default, the LCD Display is
configured to show the temperature in Celsius
(°C). However, the operator has the option to
choose between the LCD Display showing either
Celsius (°C) or Fahrenheit (°F). If the operator
wishes to toggle between Celsius (°C) or
Fahrenheit (°F), the operator can press and hold
the knob button for several seconds during this
screen until the device gives a single beep
(signaling the successful toggle). Make sure that
the displayed temperature notation is correct (°C
or °F).
STEP 3: Aim the TargetCool™ Device at a
Fixed Surface
Hold and aim the TargetCool™ device so that the
distal portion of the guard is towards a fixed
surface. The fixed surface should be flat, non-
metallic, and have a fixed temperature.
STEP 4: Press and Hold the Trigger Until You
Hear Two Beeps
Find the trigger. While aiming the TargetCool™
device to the appropriate surface, press and hold the
trigger. After several seconds of holding the trigger,
the device should beep twice, which signals that the
IR temperature sensors are properly functioning.
