AirPrimeOverview
Trident has several AirPrime models to meet your specic operational requirements.
Base Models: All models available in 2 or 3 barrel design
(depending on your water pump capacity and chassis air compressor size CFM).
Direct Mount: Models bolt directly to a Hale Q Model midship
pump’s priming port with two bolts. The Hale pump model name must begin with a Q. e.g. Qmax.
Remote Mount: This type can be used with any pump, have a
3
4" female NPT connection and require a simple bracket to hold the
unit to the frame.
Multi-Location: Priming from multiple locations.
Variations and Options:
1. The AirPrime is available in either manual and automatic single location models.
1. Multi-Location AirPrime is available in manual or automatic models.
2. Automatic versions are available in 12 and 24 Volt models.
3. Lift Gauge which indicates how much vacuum (in feet-of­water) the primer is creating to prime the pump.
4. Conversion Kits for Manual to Automatic and for adding more locations are available. Refer to Page 16.
5. AirPrime is also available for small trucks without air brakes. See Page 5 for additional information.

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 engaged�

AirPrime Primers can be used for both New and Retro-Fit installations. In Retro-Fit scenarios, AirPrime may be used to augment the
existing primer or as a complete replacement. Automatic AirPrime models provide instant re-priming of the pump when required.
An existing rotary vane primer can be upgraded to an Automatic Primer by adding a single location Auto AirPrime.

Installer Responsibilities
Air Compressor Size
1. The 2-barrel AirPrime must be used only on re pumps rated 1000 GPM [3800LPM] and less. The chassis shall be equipped with a minimum of 13.2 CFM [0. 3 74 Cubic Meters per Minute] air compressor.
2. The 3-barrel AirPrime must be used only on re pumps rated 1250 GPM [4700LPM] and more. The chassis shall be equipped with a minimum of 15.6 CFM [0.442 Cubic Meters per Minute] air compressor.
3. For Industrial Pumpers The Dual Unit requires an air compressor with greater than 20 CFM [6.09 Cubic Meters per Minute] capacity. The Triple Unit requires an air compressor with greater than 30 CFM [ 9.14 Cubic Meters per Minute] capacity.
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 midship re pump. Use the black plastic strainer provided with the re pump from Hale.
Figure #2 shows the dimensions for the tapped holes in the primer body.

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.
