• Contaminant generated in workplace and concentrations that are unknown or immediately

dangerous to life or health (IDLH).

• Oxygen concentration of the air in workplace is 19.5% or lower.

• Without complete assembling of the whole product, never use, which may cause danger for

human life.

• Do not use in sealed place, in place with danger as fire, explosion.

• Do not use the product with its power turned off since carbon dioxide concentration may

increase and oxygen level inside the face guard may decrease.

• Do not use if the product does not supply enough air.(MIN - 165 lpm)

• Do not use at workplace with strong wind. (as negative pressure generated inside the hood,

outside-air comes into the hood)

NOTICE

If bleeping alarmed, immediately get away from the contaminated area and check the
device. The hose may get blocked; Battery low power; Filter is dirty and need get changed
with new one.

A complete Tecmen PAPR System includes a blower, filtration unit, breathing tube assembly,
battery, and a welding helmet with auto darkening filter.
The blower assembly draws surrounding air through its filter and supplies purified air to the
facial via a breathing tube. There are two levels airflow rate choice: Low speed—170+lpm;
High speed—210+lpm. Switch the airflow by short press Button. Warning lights allow you to
check the filter status. More warning lights turn on, more dirty it means. When warning lights
flash, please replace the filter.

BATTERY

WARNING

The battery should be charged in a place that is electrically safe.
The charging time of different types of battery is different. Actual charging time depends on the remaining
battery capacity.
Please check out the voltage of the charger (AC 110V~220V).
Please separate the battery from the body before charging.
Upon using-condition, the battery’s life may be slightly different.

Battery is divided into standard battery, fast-charging standard battery and fast-charging
extended battery. When these three types of battery are used with different filter
components, the battery duration is different. Please choose the appropriate battery
according to actual situation.
It is recommended to choose fast-charging extended battery to match the gas filter.

Battery-charging

This indicator show the battery capacity.
When four sections show up, the battery is fully charged.
When just one section left (See fig.5a), bleeping sounds on, accompanied by vibration to
remind users to stop work and get battery charged. The frequency is bleeping sounds occur
every 30 seconds and vibration occurs every 2 minutes. After the warnings occur around 15
minutes, the battery indicator gets flashing, which shows there should be at most 15 minutes
left before the blower off (Airflow low speed 170+lpm).
Remove battery pack from blower assembly. Connect charger cord to battery terminal (See
fig.5b).
When the indicator light on charger turns from red to green (See fig.5c) , never stop it
immediately and please keep charging for another 0.5h.
