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 to

install high in the pump enclosure

. (Only required for remote mount.)

See

Figure #2

3. Non-collapsible 3/4" inside diameter (ID) air hose from primer to fire pump with 3/4" NPT fittings.
4. A Pressure Protection Valve (PPV) (Optionally available from Trident,

Part # 30.053.0

5. A 1-1/4"

[32 mm]

ID drain hose may be connected to the primer outlet using a hose clamp to secure

it in place.

NOTE:

Loosely tighten the hose clamp to avoid damage to the discharge ports. This

hose directs water from the primer to any location under the vehicle. Be sure this hose is properly
secured, short as possible and away from any moving components, free of any sharp bends and
pitched to allow drainage.

6. Liquid thread sealant or Teflon tape is required for all threaded pneumatic fittings.

NOTE:

Use sparingly while applying sealant to avoid blockage of the internal mesh filter. See

Page 5

Figure #5.

Remote Primer Mounting

1. A fabricated primer bracket to secure the primer within the pump enclosure. The mounting height for all priming components must be

ABOVE

the highest priming point on the pump suction side (or above the highest remote priming valve for multiple location systems) to

permit air removal and allow for complete drainage. See

Figure #2

for the bolt hole mounting template. An actual size bolt hole template

is provided in the primer shipping carton for your convenience.

NOTE:

Primer

MUST

be mounted

VERTICALLY

with the primer outlet discharge (round) ports facing downward as shown in

Figure #1

2. A non-collapsible hose from the 3/4" NPT cleanable wye strainer on the primer inlet to the 3/4" NPT fire pump priming port.

A 3/4" minimum inside diameter hose must be used.

3. The AirPrime and attached wye strainer must be installed in a location for ease of maintenance per

Figure #3

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, the strainer may be piped to the pump master drain by the installer. This helps in climates prone to 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 the vehicle includes a front suction inlet, adding a

Primer Front Intake

control is required. Refer to drawings of front suction

plumbing on
