exchanger to assist in engine cooling during pumping operations. The heat exchanger line shall be

controlled at the pump operator's panel with a Class 1 valve.

WATER TANK CONSTRUCTION

The tank shall have a rated capacity in U.S. gallons, complete with lifetime warranty. The tank

manufacturer shall mark the tank and furnish notice that indicates proof of warranty.

The tank shall be constructed of 1/2” thick Polyprene & Mac226 sheet stock. This material shall be

non-corrosive stress relieved thermoplastic, white in color and UV stabilized for maximum protection.

The tank shall be of a special configuration and is so designed to be completely independent of the

body and compartments. All exterior tank joints and seems shall be extrusion welded and/or contain

the Bent Edge™ and tested for maximum strength and integrity. The top of the tank is fitted with

removable lifting eyes designed with a 3-to-1 safety factor to facilitate easy removal.

The tank shall be capable of withstanding sustained fill rates of up to 1,000 GPM. All auxiliary outlets

and inlets must meet N.F.P.A. 1900 guidelines in effect at the time of manufacture.

TANK MOUNTING

A tank mounting cradle shall be supplied. The tank shall rest on the tank mounting sub-frame, and

shall be insulated from the sub-frame with a 2-1/2" wide rubber insulator. The tank shall sit cradle-

mounted using four (4) corner angles welded directly to the tank sub-frame. The angles shall keep the

tank from shifting left to right or front to rear. The tank is to be designed on the free-floating

suspension principal and shall not require the use of hold downs. The tank shall be completely

removable without disturbing or dismantling the apparatus body structure. The hosebed cross-braces

shall act as water tank retainers. The water tank cradle shall be designed to be completely

independent of the apparatus body to eliminate torsional stress loading in the body. No exception will

be permitted to the tank mounting requirements.

SECOND TANK TO PUMP

A second tank to pump piping system shall be located to the rear of the tank to allow full

evacuation/operation with the vehicle on an uphill attitude.

The 3" valve shall be an air operated valve with control switch located on pump operator's panel. A

built-in check valve shall be provided in the tank to pump supply line to prevent the unintentional back

filling of the water tank through the line.

APPARATUS BODY DESIGN AND CONSTRUCTION

The apparatus body shall be built of stainless steel and shall be designed for Fire Service use only.

The body design shall be fully tested with proven engineering and test techniques such as finite

element analysis, stress coating, and strain gauging shall have been performed with special attention

given to fatigue life and structural integrity of compartments and body support system. All welding of

body support system shall be accomplished by welders certified to the standards of the American

Welding Society for the metals being used. The body shall be constructed in accordance with current

NFPA requirements.

All metal work shall be free of sharp edges, objects or corners. Body width shall be a maximum of
