Before Use; Maintenance And Cleaning - Clean Air CA Pressure Serie Handbuch

• the user must make sure that a sufficient air flow to the hood is secured even at the maximum air consump-
tion by this accessory.
• If the unit is used in environments with high temperatures, the supply hose must be resistant to such effects.
• It is forbidden to use the unit in explosive environments.
• Before every use of the unit, check that the air flow is higher than the minimum value specified in the
technical parameters.
• If the unit stops supplying air for any reason, the user must leave the contaminated area immediately.
• When combined with a welding helmet, safety helmet or with a mask, the unit is not recommended for users
with a beard or long hair extending to the respiratory zone.
• Beware of a higher CO concentration in the air supply, which may occur if the compressor does not work
2
properly when the lubricating oil sometimes burns due to high temperatures.
• The supply air pressure must be in the range between 400 - 1000 kPa.
• The air source must be equipped with a safety valve to guarantee that the inlet pressure will be not exceeded.
• The supply pressure hoses may only be located in such areas of the workplace where they cannot be damaged.
• Pressure hoses for CA Pressure (Flow Master / For Mask) and CAP Conditioner, order No. 61 00 30 and 61 00
46, are not antistatic and the maximum temperature to which they are resistant without damage is 70 °C.
• The maximum length of the pressure hose from the compressed air distribution or CAP Conditioner to the
unit must not exceed 10 m; this only applies for combinations of products with level of protection 1A - 4A.
For combinations of products in the class 1B - 4B, the length of supply hose is unlimited.
• The recommended temperature range of use is 10 - 40 °C; at lower temperatures, use of the protective hood
or mask with air supply may be unpleasant.
• For the CA Pressure (Flow Master / For Mask) it is necessary to provide breathable air according to EN 12021.
• The CA Pressure (Flow master / For Mask) can be combined with the types of head parts shown in the picto-
rial annex on the cover of the manual. It also shows the classes for the respective combinations.
• Information on head parts is provided in the instructions on using the CA head parts.
• If using a CA Pressure For Mask, you must place a suitable two-thread filter 50 02 48 or 50 02 68 (depending
on surrounding contaminants) in between the unit and the mask. This concept will allow you to breathe safely
during possible evacuation when the pressure source stops working.
If any principle stated in this manual is not followed, the warranty becomes null and void!

3.2. Assembling the CAP Conditioner (61 00 50)
Screw the container (CAP Conditioner) down onto the stand; for the procedure see pictorial annex.
3.3. Assembly - CA Pressure (Flow Master / For Mask)
• Check that all components are in good condition, i.e. without apparent damage.
• Connect CAP Conditioner to the compressed air distribution system or straight to a compressor. If the CA
Pressure Conditioner is not used, the compressed air supply is connected straight to the CA Pressure
(Flow Master / For Mask).
• Attach the unit onto your belt and connect the pressure hose to it.
• Using the quick coupling, connect the pressure hose from the compressed air source to the CA Pressure unit.

4. Before Use

4.1. Check before use
Check before every use:
• that individual parts, particularly the air hose and sealing elements, are free from any apparent damage,
• that the hose is fitted correctly to the unit and to the head part connector,
• that the air pressure in the distribution system is in the range 400 to 1000 kPa for both the CA Pressure Flow
Master and For Mask, or in range of 300 to 1000 kPa in case of the CA Pressure unit,
• the air flow according to Chapter 4.2 - the lowest allowable flow rate is 170 lpm,
• that air is supplied from the head part.
4.2. Air flow test (CA Pressure / CA Pressure Flow Master / CA Pressure For Mask)
All the CA Pressure units are pre-adjusted to an airflow of 170 lpm. When measuring the airflow, follow the
instructions in the manual enclosed with the flow indicator. If the flow rate is different, proceed as follows:
1. Pull the control knob, you will hear a click (see. pictorial annex).
2. To set the optimal airflow, rotate the control knob counter-clockwise (see pictorial annex). To check the airflow
you can connect flow indicator.
3. Push the control knob, you will hear a click (see pictorial annex).
WARNING! The airflow should not drop below 160 lpm!

5. Maintenance and Cleaning

CA Pressure / CA Pressure Flow Master / CA Pressure For Mask
Every time you finish work, it is recommended to clean the CA Pressure unit, to check individual parts and to
replace any damaged ones.
• Cleaning must be carried out in a well ventilated room. Avoid inhaling the harmful dust settled on individual
parts of the unit and accessories!
• It is forbidden to use cleaning agents containing solvents or abrasives. Common detergents are recommended.
• The air hose can be rinsed with clean water.
• Use a damp cloth for cleaning. Each part must be wiped dry after cleaning.
CA Pressure Conditioner
• Once a week, drain the condensate from the container bottom using the drain valve located on the bottom.
side. Before this operation, it is recommended to disconnect the unit from the compressed air supply.
• Replace the filter at least once every three months. After this period, viruses and bacteria may proliferate in
the unit filter and if used regularly, the absorption capacity of the activated carbon eliminating smells may be
exhausted (if the air leaving the CA Pressure Conditioner smells in any way, replace the filter immediately).
• When replacing the filter, clean the inner part of the container with a dry cloth and common detergent.
Replacement of the CAP Conditioner filter (see pictorial annex)
• Unscrew the top part of the CAP Conditioner container (6 inbus screws).
• Remove the contaminated filter, wipe the inside of the container.
• Check the condition of the rubber seal in the top cover. If the seal is damaged, replace it.
• Install a new filter, put the container cover on and screw it back.
• Check the container for leakage. If the container is not absolutely tight, tighten all screws that fasten the top cover.
