(13)   Flex   Hose   and   Filler   Valve   Adaptor   (Air) (15, Figure 4-1) The hose assembly used to attach to scuba bottles for charging purposes b. Type  II  (Air/Oxygen)  Servicing  Unit  (See  Figure 4-2). (1) Air half of control panel (a) Air    Cylinder    Pressure        Gauge    (1, Figure  4-2).    These  gauges  are  used to show the psig of the air cylinders. (b) Cam    Lever    Valve    (2,    Figure    4-2). Primary   on-off   panel   mounted   valve controlling  the  pressure  flow  from  the air cylinders to the supply manifold. (c)   Re-charge   Connector   (3,   Figure   4-2). Servicing unit (panel mounted) connection for the breathable air servicing hose (d) Re-charge   Valve   (4,   Figure   4-2)   Air system control valve for recharging air cylinders. (e)    Supply    Manifold    Shut-Off    Valve    (5, Figure 4-2).  The supply manifold shut- off  valve  is  used  to  Isolate  the  supply manifold  from  the  purifier  and  scuba manifold. (f) Bleed    Valve    (6,    Figure    4-2).        The bleed     valve     is     used     when It is necessary to bleed off Sections of the air supply system or the total system. (g) Charge Valve, Scuba (7, 12, Figure 4- 2).  Open/closed  control  valve  that  Is used    only    when    the    breathable    air scuba tanks are being charged. (h) Air Pressure Regulator (8, Figure 4-2) The  air  pressure  regulator  is  used  to control  the  psig  of  breathable  air  that enters   the   scuba   tanks   through   the scuba manifold (i) Service  Pressure    Gauge    (9,  Figure 42). Gauge that Indicates psig available   for   use   In   charging   scuba tanks (j) Shut-off   Valve   to   Scuba   Manif   (10, Figure  4-2)  This  valve  is  used  to  shut off the flow of air to the scuba manifold from the air cylinders (k) Scuba  Manifold  Pressure  Gauge  (I  1, Figure 4-2) The gauge indicates pressure  build-up  in  the  scuba  tanks as they are being charged (2) Oxygen half of control panel. (a) Oxygen Cylinder Pressure Gauge (13, Figure  4-2).    These  gauges  are  used to    show    the    psig    of     the     oxygen cylinders (b) Cam-Lever    Valve    (14,    Figure    4-2). Primary panel mounted ON-OFF valve controlling  the  pressure  flow  from  the oxygen cylinders to the supply manifold. (c) Re-charge  Connector  (15,  Figure  4-2) Servicing unit (panel mounted) connection    for    the    oxygen    service hose (d) Re-Charge    Valve    (16,    Figure    4-2) Oxygen system control valve for recharging oxygen cylinders (e) Supply   Manifold   Shut-off   Valve   (17, Figure  4-2)  The  supply  manifold  shut- off  valve  Is  used  to  isolate  the  supply manifold  from  the  purifier  and  scuba manifold (f) Bleed    Valve    (18,    Figure    4-2)    The bleed valve is used when it is necessary  to  bleed  off  sections  of  the oxygen system, or the total system (g) Charge  Valve,  Scuba  (19,  24,  Figure 4-2)  Open/closed  control  valve  that  is used   only   when   the    oxygen    scuba tanks are being charged. (h) Oxygen Pressure Regulator (20, Figure     4-2)     The     oxygen     pressure regulator  is  used  to  control  the  psi  of oxygen   that   enters   the   scuba   tanks through the scuba manifold (i) Service Pressure Gauge (21, Figure 4- 2)  Gauge  that  indicates  psig  available for use In charging scuba tanks. (j) Shut-off Valve for Scuba Manifold (22, Figure 4-2).  This valve Is used to shut off   the   flow   of   oxygen   to   the   scuba manifold from the oxygen cylinders (k) Scuba Manifold Pressure (Gauge (23, Figure    4-2).        This    gauge    indicates pressure build-up 4-3
