Custom Fire Apparatus, Inc. <br />CAB TILT CONTROLLED AT PASSENGER (OFFICER) SIDE <br />The hydraulic powered cab tilt device is to be operated from the passenger (Officer) side of vehicle, so as <br />to allow full view of the chassis cab as it is being raised and lowered. <br />CHASSIS CAB PUSH-BUTTON TILT CONTROL CONSOLE AND CABLE <br />The push-button cab tilt control console with cable, as provided with the custom chassis, is to be <br />"shipped loose" with the completed vehicle. The quick -disconnect bulkhead style coupler plug-in is to be <br />accessible from the ground level, passenger side of the vehicle. <br />Retain Front Grille Supplied With Custom Chassis <br />COMPLIANT DPF/DEF EXHAUST SYSTEM <br />The original equipment chassis engine DPF/DEF (diesel particulate filter/diesel exhaust fluid) exhaust <br />system, upstream and downstream of the passenger side outlet, shall remain unaltered (not modified) to <br />remain in compliance with exhaust emission standards in effect at time of contract. The apparatus body <br />design and accessory installations may have to be compromised, in order to prevent interference with the <br />exhaust system components. Fabricated stainless steel heat deflector plates are to be provided, where <br />necessary, to protect body manufacturer installed components from excessive radiant heat. Exhaust outlet <br />shall terminate below body compartment floor immediately ahead of rear wheels on passenger side of <br />vehicle. <br />GATED COOLANT LINES: AUXILIARY HEATER(S) <br />Engine cooling system chassis cab heater return -to -engine line shall be separated and equipped with a <br />gate valve and .625" i.d. neoprene rubber heater hose extending to specified auxiliary heater(s). An <br />additional gate valve is to be furnished on the auxiliary heater(s)-to-engine return line. Gate valves shall <br />allow complete shut-off of the chassis cab and remote auxiliary heating system(s) that are downstream of <br />the chassis cab heater. Gate valves shall prevent hot water circulation during warm weather periods and <br />to allow shutdown should a hose or heater core leak develop. <br />COOLANT "BOOST" PUMP <br />The specified pump compartment heater core is to be piped to the engine coolant system, installation to <br />include: 12-volt in -line Groco "free -flow" centrifugal cast bronze bodied coolant "boost" pump, parallel <br />run of high grade coolant hoses with stainless steel screw type hose clamps. <br />Installation of coolant pump is to provide increased rate of coolant flow to assure maximum available <br />chassis cab and auxiliary heater core temperatures during extreme winter conditions. <br />07/26/22 <br />-70- <br />
