1. GENERAL INFORMATION
Thank you for purchasing CO2Refrigerant Leak
Detector. Read through the instruction manual before
operation for correct and safe usage. Please store
and retain this instruction manual for future reference.
2. FEATURES
CO2Refrigerant Leakage Detector uses a newly
developed optical gas sensor which is extremely
sensitive to a variety of R744 refrigerant. It provides
features of fast-response, high-reliability, and
long-durability. It is an ideal tool for maintaining
industrial heat extraction, heat pump water heaters,
chilled warehousing, supermarkets, shopping vessels,
commercial refrigeration and automotive air
conditioning.
Microprocessor Control with advanced digital
signal processing.
Multi-color visual display.
Mute function to turn off audible alarm.
High-Medium-Low leak sensitivity selector.
Low battery indication.
Optical gas sensor.
Detection gas: R744 (CO2).
Carrying case included.
15.5” (40 CM) flexible stainless probe.
Ambient concentration reset.
Peak function – find leaks in noisy environments.

4. OPERATION GUIDE
(1) The (CO2) Leak Detector unit is not equipped with
anti-explosive designs and measures. Do not use
this unit in the environment with the burnable
gases.
(2) There are some environmental conditions that
might cause error reading:
Pollutant places.
Large temperature variation.
Places with high wind velocity.
Organic solvent, adhesive vapor, fuel gas and
vesicant will cause abnormal response from the
sensor. Try to avoid the environment involved
with this substance.
Places fill with high concentration of R744 gas.

6. GETTING STARTED
6-1 Installing Batteries
Loose the screw and remove the battery
compartment door located on the bottom of the
instrument as show below (Fig.1).
Install Lithium-ion battery pack.
Reinstall the battery cover by aligning it with the
handle.
When the battery power is low, the red LED low battery
indicator illuminates. The battery should be recharged
as quickly as possible.
6-2 Charging
When the battery is being charged, the power
indicating LED will be on. It will be off after charging is
completed.
During the charging period, if the power indicating LED
blinks, it may be caused by the following reasons.
(1) Charging period is too long and the detector is
sending the warning signal. Please disconnect the
power and try again later. If the situation remains,
the battery might need to be replaced.
(2) The temperature of the battery is too high for
charging operation. Disconnect the power and wait
until it cools down then try it again.
(3) This detector is using Lithium-ion rechargeable
battery and there will not be any charging memory

effect. Frequently charging routine after use is
recommended to avoid over discharging which
could damage the battery.
6-3 Lithium Battery Care
The Refrigerant Leak Detector contains a very
powerful Lithium-ion battery. For a long battery life and
safe operation, you must observe the following:
CAUTION!
(1) Do not short-circuit battery.
(2) Do not reverse connect.
(3) Do not dissemble or reconstruct battery.
(4) Do not expose the battery to temperatures higher
than 140°F (60°C).
(5) Do not charge the battery in or nearby heated
places, such as fire, hot vehicles, or direct sunlight.
(6) Do not expose the battery to direct impact or throw
it.
(7) Do not get the battery wet.
(8) Do not deform or pierce the battery in any way.
(9) If there is any battery leakage, do not touch the
battery. In the case that electrolyte gets into the
eyes, flush with fresh water, do not rub, and see a
physician immediately.
(10) Replace immediately if there is any deformity, bad
smell, color change, or other abnormality.

6-4 Automatic Ambient Reset Feature
This Refrigerant Leak Detector features an Automatic
Ambient Reset function that sets the unit to ignore
ambient concentrations of refrigerant.
Automatic Ambient Setup - Upon initial power on,
the unit automatically sets itself to ignore the level
of refrigerant present at the tip. Only a level, or
concentration, greater than this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to
ignore any refrigerant present at turn on. In other
words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be
indicated!
