How Does It Work?

AirPrime utilizes air supplied from the chassis air brake
compressor to operate the re pump primer� This is
proven to be far more efcient and reliable than electric
motor driven rotary vane primers�

AirPrime virtually eliminates the impact load on the
electrical system improving vehicle reliability�

AirPrime also improves performance in the elapsed time
for establishing water supply resulting in improved re
ground operations and safety�

Auto Prime Move Switch to the upper position� The
Green LED light will illuminate� The primer will activate
when the OK TO PUMP light is ON and the Pump
Pressure is below 20 PSIG�
The Auto Mode only operates when the re pump is

NOTE: For operations above 4000 feet [1219 meters] of elevation and lifts greater than 15 feet [4.5 meters], a minimum air compressor size
of 18 CFM [0.510 Cubic Meters per Minute] or larger is required.

Basic Materials Supplied by Installer

1. A 3/8"OD (.251 ID) air hose from the air tank (primary or auxiliary tank) with 1/4" NPT connections (length determined by installer).

2. Primer mounting bracket. (Only required for remote mount.) See Figure #2.

3. Non-collapsible 3/4" minimum inside diameter (ID) air hose from primer to re pump with 3/4" NPT connections.

4. A Pressure Protection Valve (PPV) (Optionally available from Trident, Part # 30.053.0).

5. A 1-1/4" [32 mm] inside diameter hose may be connected to the primer outlet using a hose clamp to secure it in place. NOTE: Loosely
tighten this hose clamp to avoid damage to the primer discharge ports. This hose can direct the water that is discharged from the
primer to any convenient location under the vehicle. Be sure this hose is properly secured, kept as short as possible, free of any kinks,
sharp bends and pitched to allow drainage.

6. Liquid thread sealant or Teon tape is required for all threaded pneumatic ttings.
NOTE: Use sparingly while applying sealant to avoid blockage of the internal mesh air lter. See Page 5, Figure #5.

™

Remote Primer Mounting

1. An installer supplied primer bracket shall be installed to secure the primer within the pump enclosure. The mounting height for all
priming components must be ABOVE the highest priming point on suction side of re pump (or above the highest remote priming valve
for multiple location systems) to permit air removal and allow for complete drainage. See Figure #2 for mounting bolt hole template.
NOTE: Primer MUST be mounted VERTICALLY with the Primer Outlet discharge (round) ports facing downward as shown in Figure #1.

2. Hose from the 3/4" NPT cleanable wye strainer on the primer inlet to the 3/4" NPT re pump priming port shall be non-collapsible 3/4"
minimum inside diameter.

3. The AirPrime and attached wye strainer shall be installed in an accessible location for serviceability per Figure #3 on Page 5. The
installer may choose from one of the options below as a method of draining the strainer:

a) Remove threaded plug on wye strainer for draining during annual pump service. Refer to Page 13 for Troubleshooting Guide.
b) For draining purposes, the strainer may be piped to the Master Drain of the re pump system by the installer, especially helpful in

climates with freezing conditions.

c) Alternatively a separate drain with valve and label may be piped to the bottom of the pump enclosure by the installer.

NOTE: If a front suction inlet is provided, a REMOTE PRIMER mounting is required. Refer to drawings of front suction plumbing on Pages 11
and 12.

Primer Mounting

Figure #1 illustrates the proper mounting
of the primer to a Hale Q Series cross-frame

Air Supply, Hose and Connections

The air source used to supply the AirPrime shall be from the primary air reservoir  in Figure #4 or a secondary air reservoir (normally
used for air horns, air accessories or re pump shifting system).

The supply line from the Pressure Protection Valve (PPV)  in Figure #4 to the primer control should be a minimum size of 3/8" OD air
brake tubing and connected at both ends with 1/4" NPT ttings (connections and tubing must be rated for air brake service). The tubing
should be kept as short as possible, secured at regular intervals, free of any kinks or bends and must not be run near exhaust pipes
(Stay 6" [150 mm] away from any exhaust or hot components), mufer, or rotating shafts. Use grommets to protect the tubing lines from
contacting sharp edges at hole locations.

When the length of tubing required exceeds 20 feet [ 6.1 m] , a minimum size of 1/2” OD air brake tubing should be used.

Pressure Protection Valve (PPV)

The Pressure Protection Valve (4) is not supplied with the basic primer kit. A Trident PPV, Part #30.053.0
may be purchased separately, a Bendix PPV, Style PR-4, Part #288323 or its equivalent may be used.

The PPV valve must be installed per Figure #4 between the primary air supply reservoir  and the
AirPrime primer air inlet. The valve protects the air brake system from any leaks that may occur in the
primer control or the line from the PPV to the primer control. The pressure setting for the PPV is 80 PSIG
maximum.

Air Filter Port

This cleanable porous lter is located inside the top of the primer body, below the threaded area on the
air supply connection or solenoid connection. See Figure #5.
A replacement lter is available as Part #21.002.0. When replacing, the domed side faces up.

b) The priming valve is “stuck”, check for damaged O-Ring or check to see

that the piston is still fully threaded on the valve stem.

Remove any obstructions or debris from hose strainer, do not allow suction
hose or strainer to rest on the bottom of water supply.

Clean and tighten all suction hose connections, check hose washers and
replace as necessary.

Suction hose should be positioned with a constant decline to the water supply.
If a trap is unavoidable, repeated priming may be required to eliminate air

AirPrime™ Fire Pump Priming System

Annual Primer Testing

The AirPrime™ primer is designed to meet the NFPA requirements of: Dry Vacuum (TEST #1) and Priming Time (TEST #2). These tests
should be performed on an annual basis, or whenever major repairs or modications have been made to the re pump, plumbing or primer.

TEST #1 Dry Vacuum Test: Checks the primer’s ability to produce 22 inches (Hg) [.74 5 B a r] of vacuum, and the pump and plumbing’s

ability to hold that vacuum. The test may be run with the pump in gear or not engaged. Never run a dry pump at engine speeds above
1200 RPM. There is no time requirement for the vacuum to reach 22 inches. If the compressor has a capacity of 13.2 CFM [374 cu. cm.
displacement], it can take several minutes to reach 22 inches [.75 Bar]. This time can be shortened by not engaging the pump and increasing
the engine speed to 1200 RPM. The test process is as follows:

1. Drain all water from pump and plumbing.

2. Close all valves and drains. Cap all suction openings and the outlet off of the suction side relief valve (if so equipped).

3. Connect a test vacuum gauge to the intake test gauge connection on the pump panel.

4. Operate the AirPrime with the air system at over 100 PSIG [ 7. 0 B ar ] pressure, air tanks lled to capacity, and at 1000 RPM engine
speed; until the vacuum gauge indicates 22 inches (Hg) [.75 Bar] or more of vacuum. (If the primer is an Automatic AirPrime, use the
PRIME mode switch position to engage the primer).

5. Watch the gauge, if the vacuum falls more than 10 inches in 5 minutes the test has failed and is a certain indication of an air leak(s).
Vacuum leaks may be detected by ear, with the engine turned off. Correct leaks immediately and test the priming system again.

™

TEST #2 Priming Time Test: This test is to prove that the re pump and primer has the capability of attain a prime and creating

discharge water pressure in a set period of time. This test is also conducted by the apparatus builder prior to delivery. The re pump shall
be engaged and primer actuated. The test is part of an annual pump performance test and is performed as follows:

1. Set up the apparatus in accordance with the pumping test outlined in the NFPA standards.

2. Engage the pump, and increase the throttle to a maximum engine speed of 1000 RPM.

3. Operate the AirPrime with the air system at over 100 PSIG [ 7. 0 B ar ] pressure, air tanks lled to capacity, and at 1000 RPM engine
speed.

• For the Manual controlled primer, release the push button when a discharge pressure over 20 PSIG [1.4 Bar] is obtained.

• For the Automatic AirPrime, place the switch in the AUTO position, it will turn the primer off automatically when priming is attained.

4. The time to prime should not exceed 30 seconds for 1250 GPM [4700 LPM] and smaller pumps. The time to prime should not exceed
45 seconds for 1500 GPM [5600 LPM] and larger pumps. An additional 15 seconds is allowed for pumps with auxiliary suctions using
4" or larger piping.

Higher lifts and operating at higher elevations will slow down time to prime. The air compressor rating should be a minimum of 18 CFM
[410 cu. cm. displacement] for elevations over 4000 feet [1200 m] and lifts in excess of 15 feet [4.5 m]. Operation at these extremes may
require the primer to be operated at engine speeds in excess of 1000 RPM without engaging the pump, until water reaches the impeller.
Never run a dry pump at engine speeds above 1200 RPM.

IN-SERVICE OPERATIONAL TEST (Ramp Test)

The integrity and operation can be quickly checked (on a daily or weekly basis) as outlined below, without re pump engagement:

1. Drain all water from pump and plumbing.

2. Close all valves and drains. Cap all suction openings.

• Operate the AirPrime with the air system at over 100 PSIG [7.0 Bar] pressure, air tanks lled to capacity, and the engine running at

1000 RPM (with an Automatic AirPrime electrically controlled model, use the PRIME mode switch position).

3. Stop running the primer.

Time to reach 15 inches HG [.50 Bar] or 17 feet [5.0 m] on lift gauge should be within the time allowed in list below for the pump tested.

Small Body Pump (Up To 1250 GPM): Vacuum Time

10 inches HG [.33 Bar] (11 feet) 6 Seconds
15 inches HG [.50 Bar] (17 feet) 15 Seconds

Large Body Pump (Over 1250 GPM): Vacuum Time

10 inches HG [.33 Bar] (11 feet) 8 Seconds
15 inches HG [.50 Bar] (17 feet) 20 Seconds

Note: Vacuum Time listed in the table at left are for operations up

to 2000 feet [609 m] of elevation. When running this In-Service
Operational Ramp Test at higher elevations, the vacuum should be
reduced by 1 inch (1.13 feet) for each 1000 feet [304 m] of elevation
over 2000 feet [609 m].
