4. Before use
4.1. Inspection before use
Each time before starting work check that :
�
all components are in good condition with no visible damage (like holes, tears etc.) Replace any
damaged or worn parts. Carefully examine the air hose, seals and the facepiece.
�
there is a good connection between the air hose and the headpiece as well as the blower unit
�
there is sufficient air flow. (see chapt. 4.2.)
�
the air is supplied through the whole respiratory system from the blower to the hood.
Charge the battery before the first use, see chapt. 6.2.
4.2. Air Flow Test
CA BASIC 2000 DUAL FLOW
1. Disconnect the air hose from the hood.
2. Insert the indicator (the light ball) into the air hose connector and keep the hose in vertical position at
about the eye level.
3.
Switch the power unit on. The airflow is sufficient if at least half of the indicator can be seen. If the
indicator sinks deeper into the hose connector, the airflow is less then 120 l/min. In that case it is
necessary to charge the battery or change the filter. If the problem still persists, see chapter 7 for
additional suggestions.
CA BASIC 2000 FLOW CONTROL
1. Disconnect the air hose from the hood.
2. Cover the disconnected end of the air hose with your hand. The blower starts to run faster after about 20
seconds, the audible alarm activates and the LED diodes on the control panel start blinking.
3. Release the hand . The blower speed should decrease.
If the blower speed does not change, it is necessary to check the unit as described in chapter 7.
5. Maintanence / Cleaning
It is recommended to clean the respiratory system after each use. Also inspect all parts and replace any which
are damaged or worn.
•
Always clean the respiratory unit in a ventilated room or outside. Be aware of harmful dust settled on
any parts of the unit.
•
Never use flammable cleaning liquids or abrasive cleaners !
•
The outer surface of the blower unit can be cleaned with a soft cloth wet slightly in a mild solution of
clean water and mild detergent. Dry it properly afterwards.
•
Ensure that no water or detergents enter into the blower unit !
•
The air hose itself, detached from the blower unit and the headpiece, can be rinsed in clean water.
6. Spare parts / Replacing spare parts
6.1. Filter
CA BASIC 2000
The respiratory power unit is equipped with a high efficiency particle filter of class PSL.
The filter must be regularly checked (see Air Flow Test - chapter 4.2.) and replaced.
Make sure that the new filter is within its expiry date, unused and not evidently damaged.
From the hygienic point of view the maximum working time of a filter is 180 hours and should not be exceeded.
It is prohibited to clean the filter by any procedure!
The particle filter can be used with a Pre-filter or with an Odour filter which removes the unwanted smell of
harmless gases.
CHANGING THE FILTER OF CA BASIC 2000
…................... see picture supplement no.1
pict. 1A : Removing the filter cover: Face the silver filter cover towards you. Put your index fingers and middle
fingers into the gaps between the body of the unit and the filter cover on both sides.
pict. 1B : Rest your thumbs on the top of the silver filter cover. Then pull your fingers placed in the gaps
outwards lifting the filter cover off the unit. ATTENTION! It is strictly forbidden to use any tools to
uncover the filter.
pict. 1C : To remove the filter, take it out while rotating it. Clean the unit from dust.
pict. 1D : Inserting a new filter: If you are using a prefilter or an odourfilter, fix it around the new filter as tight as
possible and stick the ends together using the sticky tape which is prepared on the prefilter/odourfilter.
Put the filter back into position using the same rotating motion and gently push until it fits well on the
body of the unit . Cover the filter with the silver filter cover. Pay special attention to snap the cover
properly (on both sides).
