INTRODUCTION
The monitor is designed to be wall-mounted or ceiling
mounted indoors. Mount in a clean, dry location away
from windows, air ducts, and other places where
environmental factors may affect readings. If you mount
the unit on the interior of an outside wall, thoroughly
insulate so outside air behind the sensor does not affect
the sensor reading.
When installing this product
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and
marked on the product to make sure the product is
suitable for your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check the product
operation.
5. Be sure wiring complies with all applicable codes,
ordinances and regulations.
WARNING
Electrical Shock Hazard
Can cause severe injury or death.
Disconnect the power supply before beginning
installation to prevent electrical shock and
equipment damage. More than one power supply
may have to be disconnected.
Location
Do not install the unit where it can be affected by:
• drafts or dead spots behind doors and in corners.
• hot or cold air from ducts.
• radiant heat from sun or appliances.
• concealed pipes and chimneys.
• unheated (uncooled) areas such as an outside wall
behind the unit.
IMPORTANT
To avoid electrical interference, which can cause
erratic performances, keep wiring runs as short as
possible and do not run unit wires adjacent to the
line voltage electrical distribution systems. Use
shielded cable. The cable shield must be grounded
only at the controlled equipment case.
WALL MOUNTING LOCATION
Install the Monitor about 1.5m-1.8m above the floor in an
area with good air circulation at average temperature. (See
below Fig).
Fig. 1. Selecting sensor location
CEILING MOUNTING LOCATION
Install the Monitor on the ceiling, about 2.5m-3m above
the floor in an area with good air circulation at average
temperature.
WEEE (Waste of Electrical and
Electronic Equipment)
• At the end of the product life, dispose of the
packaging and product in an appropriate
recycling center.
• Do not dispose of the device with the usual
domestic refuse.
• Do not burn the device.
This symbol on our product shows a crossed-out
“wheeliebin” as required by law regarding the Waste of
Electrical and Electronic Equipment (WEEE) disposal.
This indicates your responsibility to contribute in saving
the environment by proper disposal of this Waste i.e. Do
not dispose of this product with your other wastes. To
know the right disposal mechanism please check the
applicable law.
Precautions
1. The monitor is used for indoor air quality monitoring
and is suitable for ceiling installation and wall instal-
lation. This product should not be used outdoors.
2. The installation location should avoid kitchens,
heating, air conditioning indoor units, direct sun-
light, etc., which are affected by heat sources and
other polluting gases. Keep away from high power or
electrostatic precipitator equipment to avoid affect-
ing product accuracy. The installation location
should be convenient for regular maintenance.
3. This series of products is precision measuring
equipment, and the measurement parameters
include micro-particles and total volatile gases, and
it should be ensured that there is no construction or
decoration in the environment. When used in new
construction, it should be installed after the renova-
tion project is completed and cleaned.
4. If the room where the monitor has been installed
needs to be renovated, the monitor should be
removed before the conditions permit, and then
installed after the renovation is completed. For situ-

C7355A ROOM IAQ MONITOR
331-00436—01
ations where disassembly is difficult, be sure to com-
pletely wrap the monitor to prevent paint and dust
from entering the monitor.
5. This product should avoid being dropped or hit,
which may cause the light beam deviation in the
sensor chamber, resulting in deviation of CO2 mea-
surement; it should avoid the long-term exposure of
the product to the high concentration of total
organic volatile gas, which may cause the sensor
poisoning to be unrecoverable. For example, the
concentration is greater than several times the
TVOC range in the monitor.
6. When the temperature of the monitor environment
changes greatly, for example, if the product has just
been received during the cold weather, it should be
placed indoors for 8 hours before being powered on.
Or move from the air conditioned room to the non-
air-conditioned area, etc., and also need to be placed
for at least 2 hours before powering up. Avoid exces-
sive temperature difference and cause condensation
or equipment damage.
7. DO NOT PAINT monitor or expose to heavy dirt or
dust.
8. Do not use cigarettes to test PM2.5 measurements.
The particles of cigarettes are mostly between 0.1
and 0.3 microns, and the concentration cannot be
controlled. As a result, the PM2.5 measurement
deviation is too large.
9. When multiple monitors use RS-485 wired network-
ing, when sharing a power supply, make sure that
the power supply wiring uses the same name of the
power polarity, and the wrong connection may cause
damage to the equipment.
10. Re-use after first use orextended time, it should be
continuously energized for more than 48 hours to
ensure stable output of all measured values.
11. The built-in CO2 sensor of this monitor has a self-
calibration function. The readings may show devia-
tions after power on or after a period of power off.The
readings will return to normal after 2-7 days of con-
tinuous power. The sensor will automatically re-cali-
brate during long term use.
12. Please note that the automatic detection time of the
device firmware is one minute after the monitor is
powered on. At this time, the indicator of the monitor
does not light, and the communication fails to con-
nect. Please be patient and wait for the automatic
detection of the monitor to complete. When the indi-
cator light turns on, it can be used normally!
