3 Connecting and Operating the Equipment
Before the BAS-3015 / BAS-3015M is installed, the piping should be purged with clean dry air to remove any loose debris and/or water from the
line. Downstream piping must be of a type approved and specified for breathing air applications.
The BAS-3015 / BAS-3015M must be operated in a vertical position and must not be situated where it is able to tilt or be dislodged from its
operating position.
The BAS-3015 / BAS-3015M must only be used in the direction of flow indicated on the cabinet. No attempt should be made to remove the
filters from the cabinet or loosen any of the retaining bolts which could cause malfunction of the purifier.
Ensure that all connections to the purifier are secure and that compressed air of the correct pressure and flow rate is available to the purifier.
Ensure that the BAS-3015 / BAS-3015M is securely sited and all air supply lines are safely positioned and not susceptible to damage or
constriction.
Air can be supplied from most suitably rated compressors, although care should be taken to ensure that the compressor is operating efficiently
and not overheating. Care should also be taken in the location of the compressor intake to ensure that no harmful contaminants are drawn in.
For heavily contaminated compressed air systems a water separator is recommended which will reduce liquid water and oil.
Under normal circumstances, it is not usual to encounter CO concentrations in excessive levels. If detected then the purifier must not be used.
Provision for air sampling should be made to prove the quality of delivered air using a certified testing agency.
3.1 Operating the Equipment
3.1.1 BAS3015
To adjust the line pressure locate the outlet pressure regulator behind the small BA access panel, lift the locking ring and open the regulator.
Turn clockwise to increase the secondary pressure or anti clockwise to decrease the pressure.
It is recommended that adjustments are made under flow conditions.
Note: There may be a slight increase in set pressure when flow demand stops until the desired conditions are achieved for the
operators breathing equipment.
Push down the locking ring to lock. Do not exceed the rated flow. Set the manifold pressure in accordance with manufacturers specifications for
the respirators.
When the operating condition has been achieved, the breathing air purifier will operate automatically without further adjustments providing that
the inlet supply remain stable within the specified limits.
Disconnect at the coupler when the air demand is no longer required.
Any disconnection of the purifier must only be made when the system pressure is fully relieved.
3.1.2 CO Analyser
Rechargeable Battery
The ‘Version 1’ Analyser incorporates a rechargeable Battery which can be used as power backup in the case of a mains power failure or as the
Analyser’s main operational power source, but which will require periodic re-charging by connection of the Analyser to the external power
source.
When the Version 1 Analyser is powered from the 9VDC external power source, the battery is continuously float-charged and monitored during
normal operation. In the event that the external power supply to the Analyser is interrupted during normal operation, the battery will continue to
provide power for the Analyser to maintain its operation for a period of time.
When the battery discharges to a certain level, a Low battery alarm will appear on the Analyser display to indicate approaching cessation of
Analyser operation and that recharging of the battery is needed.
The battery charge indication is applicable to both the ‘back-up’ and main operational mode of battery use.
The length of time for which the battery will support analyser operation is contingent on the operational condition of the Analyser. i.e. if the
Analyser enters into alarm mode frequently, activating the associated sounder and Relay, battery power used will increase and remaining
operational time reduced accordingly.
Battery charging is indicated by a bar graph image on the left hand side of the Analyser LCD display. Oscillating bar graph elements indicate
Only competent personnel trained, qualified, and approved by Parker domnick hunter should perform installation,
commissioning, service and repair procedures.
