2.4.3.6 Water Detection Sensors
The water detection sensor detects the presence or absence of water.
Do NOT attempt to R&R the sensor before seeing paragraph 4.7.6 (page 84) to prevent sensor
damage and for other sensor information.
See paragraph 4.15.2 (page 145) to check/test the sensor.
2.4.3.6.1
Autolube Water Detection Sensor Protection Solenoid
The water detection sensor protection solenoid installs in a special tap in the autolube assembly
providing protection for the water detection (water in oil) sensor and an Autolube oil drain.
Do NOT attempt to R&R the solenoid before seeing paragraph 4.7.6.1 (page 86) to prevent sole-
noid damage and for other solenoid information.
2.4.4
Pump Priming And Air Bleed
SAM utilizes the components described below to evacuate air from the pump, MIVs, and LDH wa-
ter sources. Locate and connect these components to facilitate drainage and route the associ-
ated tubing to facilitate detection of water at the primer.
DO NOT RUN THE PRIMER FOR MORE THAN 45 SECONDS. IF PRIME IS NOT ACHIEVED
IN 30 - 45 SECONDS, STOP AND LOOK FOR AIR LEAKS OR BLOCKED SUCTION HOSE.
2.4.4.1 Pump Primer (ESP)
The Hale ESP primer operates from a separate 12 VDC (do NOT connect the ESP to the same
wire as the rest of the SAM system). Hale recommends the use of a separate power switch, cir-
cuit protection/isolation, and cabling (minimum 1 AWG fine stranded coper wire – not to exceed
7.5 ft total length [pos & neg run]) capable of 300 Amps. Reference Hale 029-0810-01-0, ESP
Primer System Installation, Operation and Service Maintenance Manual for primer information.
Do NOT connect the ESP to a load shedding circuit.
2.4.4.2
Priming Feature Valve Assembly
The PF valve assembly is comprised of multiple components: PF air cylinders, SAM PF valves,
and air lines and fittings. The pump body PF valve and SAM drain valve are always present on
every SAM system. One [1] PF valve is added to the assembly for each Hale master intake valve.
Each rectangular brass valve block is closed/opened by a PF air cylinder. Each air cylinder is con-
trolled by a 4-way air valve all of which are controlled by the MIV modules to connect the system
primer (the ESP) to individual components as directed by SAM automation.
Do NOT attempt to R&R any assembly before seeing paragraph 4.9.2 (page 103) to prevent as-
sembly damage and for other assembly information.
See section 4.15 (page 145) to check/test the assembly.
2.4.4.3
Air Bleed And Check Valves
SAM automated air bleed is comprised of multiple components: SAM air bleed solenoids, check
valves, and air lines and fittings. One [1] air bleed solenoid and check valve assembly is provided
for each Hale master intake valve. Each solenoid is controlled by the MIV modules to connect the
supply side (LDH) of the MIV to the prime detection components as directed by SAM automation.
Do NOT attempt to R&R any assembly before seeing paragraph 4.9.4 (page 106) to prevent as-
sembly damage and for other assembly information.
See section 4.15 (page 145) to check/test the assembly.
