WARNING
Oxygen deficient atmospheres.
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
headtop, outside-air comes into the headtop)
In the power-off state little or no respiratory protection is to be expected, and that this
is considered to be an abnormal situation.
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.
Please EXIT that contaminated place in any cases below:
IF some problem is shown in any part of the product, for example, the air supply is
stopped or its amount is decreased.
IF it gets hard to breathe, feeling dizzy or headache, feeling the smell or taste of the
contaminants and its stimulus occurred.
Never use in place with too high level of contamination.
Make sure the connecting hosepipe smooth and is not entangled or is in the way of
other items in the area.
Don’t remove the respirator until you are in a safe area.
Operating temperature range between -20°C and +60°C.
The TECMEN PAPR system is not intrinsically safe. Keep away from flammable, or
explosive atmosphere.
At very high work rates the pressure in the device may become negative at peak
inhalation flow.
Do not confuse the European standard EN12941 with other standards.

DO NOT USE FOR

A complete Tecmen PAPR includes a blower, filtration unit, breathing tube assembly,
battery, shoulder strap and belt.
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 fast-charging standard battery and fast-charging extended battery.
When these two 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.

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.

Make sure tube is not damaged and connected locked to the blower unit and headtop.
Battery
Check connection to blower unit is secure and battery is fully charged.
Airflow rate test / Alarm sound check
It’s necessary to do both airflow rate test and alarm sound check before use. Testing
method refers to page 9.
ENTER AND EXIT CONTAMINATED AREA
Before using respirator - Check the following items.

After turning on the product, check the alarm sound warning function by blocking the air
outlet as fig.10 shown in the picture above. The warning signal on the panel should flash
with a sound and blower vibrate (approximately 15 to 30 seconds after the outlet is
blocked). The product is working correctly if the warning functions follow the process
above.
(Please make sure the filter is equipped and the battery is fully charged before doing this
test.)
SELF CHECK BEFORE EACH TIME USE
ALL THE TESTS MUST ALWAYS BE DONE IN A SAFE ENVIRONMENT.
Alarm sound check

BLOCK AIR FLOW
WITH HAND
Take off headtop and disconnect tube from headtop.
Turn off the blower by long press button.
Release belt. Remove straps from shoulders and remove blower off of your lower back.
IF some problem is shown in any part of the product, for example, the air supply is
stopped or its amount is decreased;
IF it gets hard to breathe, feeling dizzy or headache, feeling the smell or taste of the
contaminants and its stimulus occurred;
NEVER use in place with too high level of contamination. If you suspect the levels reach
a level which this respirator may no longer provide enough protection.
WARNING
Never remove the respirator in areas where the air is contaminated.
Always take off the PAPR after you step out of the workplace.
Respirator removal
Always exit the contaminated area immediately if any of the following
conditions occur:

Steps

Airflow rate test
Take airflow test always before using this product.
Make sure all the components are fully assembled before testing.
Connect the end of hose to the bottom of airflow indicator and then start the Button. Keep
the Flow Indicator vertical (See fig.11).
If the ball inside the pipe floating above the limited line in low speed mode, it proves
normal function.
If the ball cannot float up to limited line, please refer to Trouble-shooting Guide on
page11.
MAINTENANCE
The respirator components must be cleaned, inspected and prepared for next use after
each use. Use soft cloth dipped in mild soap water for wiping. Be careful for the water NOT
to get inside the body.
CLEANING
Blower unit and battery pack: Clean the outer surfaces of the PAPR and battery pack
with a soft cloth dampened in a solution of water and mild, pH neutral detergent. Be
careful for the water NOT to get inside the body. Do not use solvents or abrasive
cleaners. Ensure the electrical contacts of the motor/blower and battery pack are dry
before assembling well.
Breathing tube: Wiping the exterior is insufficient. Clean the outer hose and connection
on the breathing tube with the soft cloth dipped in water and detergent solution.
Optional breathing tube covers can also be used to facilitate cleaning. Ensure the
breathing tube is completely dry before using or storing. They cannot be immersed in
liquids for cleaning and must be replaced if wet.
Filter: Open the filter cover and inspect all the filters and spark screens. The Particle, gas
and pre-filters cannot be cleaned. The spark screen can be cleaned using a clean, soft
cloth dipped in a solution of water and a mild pH neutral detergent. Completely dry the
spark screen with a clean cloth. Replace the pre-filter and Particle filter if excessively
dirty, wet or damaged. Do not attempt to remove contamination using a compressed air
line as this will automatically invalidate the warranty. If the spark screen cannot be
cleaned or is damaged, replace with a new spark screen.
