10. Maintenance
We recommend to manually test CO
cause of false alarms. Therefore, clean the CO
accumulated dust along the sides of the CO
Clean the device with a soft, damp and lint-free cloth. Make sure that no moisture enters the housing. Do not use any
sprays, solvents, alcohol-based cleaning agents or abrasive cleaners, but only clean water to moisten the cloth.
11. Warnings
This manual contains important safety information about the CO
Read the manual carefully and keep it in a safe place for future reference.
Do not open the device in case it is damaged.
Do not remove any safety signs, stickers or labels from the device.
Keep all safety signs, stickers and labels legible condition.
This product cannot be used in factories, warehouses and other industrial environments that may be in high CO
concentration for a long time.
If the product is to be placed in a narrow space, the space should be well ventilated, especially the two diffusion
windows should be in a well-ventilated position.
The product should be away from heat source and avoid direct sunlight or other thermal radiation.
This product should not be used in the environment with high dust density for a long time.

much fresh air = energy wasted).
ASHRAE and OSHA recommended maximum level in a closed room.
Considered maximum comfort level in many countries.
Poor air quality - requires ventilation.
According to many studies this level of CO
headache lower levels of concentration and increased likelihood of spreading respiratory viruses
like colds, etc.
OSHA and NIOSH first threshold for safety. Maximum allowed concentration within an 8
