INSPECTION, CLEANING AND DISINFECTING
Before each use, the unit should be inspected for the following points. This helps to determine
that the unit is operating as it was designed and it is suitably protecting the operator:
1.
PX5
®
PAPR SYSTEM: Make a visual inspection of the entire unit, which includes the motor
housing, filter door and door cover, filter and pre-filters, battery, belt and breathing tube. Also
inspect that an approved hood is attached.
2.
BATTERY PACK: Check that the battery has full charge to confirm that there is sufficient
charge for the work period that you need to accomplish. Make sure that the battery door
seal is in good condition and the door is securely closed.
3.
BREATHING TUBE: Inspect the breathing tube completely, looking for splits and cracks
in the tube, the fittings are held securely in the tube and that the seal is in place on the
bayonet fitting that inserts into the PX5
®
. Make sure that the breathing tube fits firmly into
the PX5
®
and seals without any leaks around the connection. See Fig 5.3 and 5.4
4.
HE FILTER: Inspect the filter casing for cracks and distortions that will affect the seal to the
PX5
®
unit. Inspect the filter paper and the seal carefully for any of the following defects; dirt,
cuts and tears, distortions or indentations. The seal can be wiped clean with a damp cloth
to remove dirt particles. Do not use solvents or detergents. The HE filter paper must not be
cleaned or submersed in water at any time. Damage to the HE filter paper will affect its
ability to filter the air and could expose users to harmful environments. All damaged filters,
pre-filters and spark arresters must be replaced before using the PX5
®
.
5.
AIRFLOW METER: Check the ball in the 03-819 airflow meter is moving freely and that the
tube is free of debris.
6. ALARM SIMULATION: Check the operation of the airflow alarm is functioning correctly.
Power on the PX5
®
and wait for 5-10 seconds for it to reach nominal flow. Then place the
palm of your hand over the outlet on the PX5
®
. Continuing to hold your hand tightly over
the outlet, with the airflow restricted until the alarm sounds, (audible alarm, vibration, and
red LED indicator on the User Interface) after 5-10 seconds, indicating that the airflow is
below the minimum airflow. Remove your hand and the alarm and LED should return to
normal operation once the airflow is back to safe levels.
7.
CLEANING: The PX5
®
unit can be cleaned with a damp cloth and diluted mild, pH neutral
detergent or diluted isopropyl alcohol (70% IPA or lower) on the external surfaces and
the face of the fan motor housing for dirt and contamination. Do not use organic solvents,
abrasive cleaners or high percentage ethanol. If you are unsure about the use of cleaning
chemicals on the PX5
®
unit please contact RPB
®
. The PX5
®
should not be submersed in
water, cleaning solution or placed in a respirator washer. A cleaning kit that allows the PX5
®
to be submersed will be released at a later date.
8.
BELT SUPPORT BRACKET OR BACKPACK: Check the Belt Support and belt for cracks, rips,
or tears. If cracks or excessive wear is present, they should be replaced. Follow the belt
replacement instructions.
