4. USING POWER CAP
Unit
The Powercap meets the THIP requirements of EN12941:1998 this offers an assigned protection factor (AFP) of
10x Workplace exposure limit (WEL) for fine non-toxic, fibres, fumes and dusts.
Filters
The filters provided are high efficiency sub-micron particulate types supplied in pairs. They will filter most
particulate matter such as dust, spores, mist and fumes, but like all filters cannot filter out all particulate matter
present in the air. They will not filter gases, vapours or toxic substances.
The duration of filter life will depend mainly on the amount and size of the contamination in
the area where they are used, and the time used in that area. Inspect the filters regularly.
Ensure that they are located correctly and carefully remove any visible large surface
contamination to prolong their life. The filters must not be washed or allowed to get wet. A
low airflow reading (red section of indicator) usually indicates that new filters are required.
Fitting and replacing the filters:-
Only replace with a pair of genuine replacements supplied in pairs from JSP Ltd or it's distributors.
Push and twist the replacements firmly into place.
Recheck airflow when the new filters have been fitted before use.
If the filters are not fitted correctly, the filter efficiency may be severely reduced.
Battery and Airflow Check :-
PowerCap has a Minimum Design Flow rate of 140 l/min
To check battery charge and airflow the filters must be fitted and the visor removed.
Simply twist anticlockwise, with filter towards you, and lift
away from motor housing.
Replacement is the reverse procedure. Ensure that the filter
and motor housing mating faces are clean, do not allow any
dust or objects to fall into the motor housing.
a. Join the connector at the end of the Power Cap "flying lead" to
the mating connector at the end of the "flying lead" of the
battery compartment, ensuring that the "white marks" on each
connector are aligned. (Not Powercap Lite)
b. Switch unit on. Airflow will now commence within the visor. It is
now necessary to check that the airflow within the visor is sufficient,
and the following checks should be carried out on a regular basis
with the filters fitted and always before use of Power Cap :-
b.1. Invert (turn upside down) the Power Cap and fit the Airflow
Indicator supplied over the air outlet in the brim of the cap
ensuring a good seal. Avoid placing hands or other possible
obstructions over the two filter inlets.
