Custom Fire Apparatus, Inc. <br />must be tilted to access the shut-off valves. Any component which needs to be accessed to perform <br />system troubleshooting shall be accessible by one person using basic hand tools. Regularly serviced <br />items shall be replaceable by one person using basic hand tools. <br />"The chassis manufacturer recommends that the overall climate system performance be based off <br />third party testing in accordance with the Society of Automotive Engineering standards as a complete <br />system. <br />Individual component level BTU ratings is not an accurate indicator of the performance capability of <br />the completed system. System individual component BTU ratings: <br />• Air conditioning evaporator total BTU/HR: 82,000 <br />• Air conditioning condenser total BTU/HR: 59,000 <br />• Heater coil total BTU/HR: 98,000 <br />Performance data specified is based on testing performed by an independent third party test facility <br />using a medium four -door 10" raised roof cab equipped with an ISL engine. <br />CLIMATE CONTROL DRAIN <br />The climate control system shall include a gravity drain for water management. The gravity drain shall <br />remove condensation from the air conditioning system without additional mechanical assistance. <br />CLIMATE CONTROL ACTIVATION <br />The heating, defrosting and air conditioning controls shall be in the center dash center switch panel, in a <br />position which is easily accessible to the driver. The climate control shall be activated by a rotary <br />switch. <br />HVAC OVERHEAD COVER PAINT <br />The overhead HVAC cover shall be painted with the same color paint as the primary exterior cab color or <br />the lower exterior color of the cab if a two-tone. <br />AUXILIARY CLIMATE CONTROL FRONT UNDERSEAT <br />Two (2) 13,500 BTU heaters shall be provided and installed in the face of the seat riser storage area for <br />the left and right front seats, one (1) each side. The heater fan controls shall be individual switches <br />located in the rocker switch area of the dash. <br />The auxiliary heater system hoses shall be silicone with stainless steel constant torque clamps approved <br />for use with silicone hose. All defrost/heating systems shall be plumbed with one (1) seasonal shut-off <br />valve at the front corner on the right side of the cab. The cab must be tilted to access the shut-off valve. <br />HEATER HOSE INSULATION <br />The heater hoses leading from the engine to the cab shall include a foam insulation wrap which runs the <br />length of the hose improving heating in extreme cold climates. The heater hoses which shall be routed <br />inside the cab shall not be insulated. <br />A/C CONDENSER LOCATION <br />07/26/22 <br />-39- <br />
