2.4.4.4 Manual Prime/Air Bleed
In the event that SAM automated priming is inoperative, SAM provides a traditional PRIME button
(wired direct to primer). To provide traditional air bleed for the Hale MIV 2.0s, each SAM MIV
override panel houses a mechanical air bleed valve (Blue handle).
2.4.4.4.1
Manual Pump Priming
SAMs traditional PRIME button wiring differs slightly from typical wiring, in that blocking diodes
are required. See paragraph 4.9.1 (page 102).
2.4.4.4.2
Manual Air Bleed
SAM provides an MIV override panel for each Hale MIV 2.0. The associated panel houses a me-
chanical air bleed valve which has a Blue handle. To prevent the valve from interfering with auto-
mated priming, a check valve is attached to each air bleed valve. Do NOT attempt to R&R any
MIV override pane before seeing paragraph 4.4.7 (page 62) to prevent assembly damage and for
other panel information.
2.4.5
Water Supply Management
Most Hale MIV 2.0 and auxiliary (pony) intakes are installed and all are intakes are tested at
Hale. All pony intakes utilize an Akron Brass motorized Swing-Out™ valve which are also config-
ured at Hale. Some intakes are shipped loose (NOT installed at Hale).
SAM can operate up to five (5) master intake valve intakes and up to four [4] pony intakes, how-
ever, SAM can ONLY provide automated control for a maximum of four intakes at one time. SAM
allows those four valves to be any mix of master intake valve and pony intakes.
The pony intakes are optional for a SAM system and typically provide a 2.5-inch intake. (For a
complete Akron Brass valve listing available for pony intakes, reference the SAM Parts Manual,
FSG-MNL-00212.) SAM supports up to four [4] pony intakes, to do this each intake is controlled
via a separate Akron Brass motorized Swing-Out™ valve. All the Akron Brass auxiliary intake
valves utilize a unique address (static verses the default dynamic); therefore, off-the-self Akron
Brass valves can NOT be used to replace these valves. See Table 1 for addressing required for
Akron Brass valves utilized as a SAM pony intake.
Pony intakes do NOT utilize air bleed, automated primer suction, or pressure sensor ports. It is
important to note that SAM does NOT provide automated air bleed or pre prime for pony intakes.
Additionally, SAM does NOT support drafting from a pony intake in Auto Mode.
Table 1 lists the Akron Brass motorized Swing-Out™ valves available in the SAM system for water
supply management (intake) purposes. The firmware in these valves is unique to each valve, do
NOT utilize a valve previously programed as a discharge valve to replace a special purpose valve
or interchange special purpose valve positions. The following sub paragraphs provide removal
and installation and SAM configuration instructions.
