Specifications

The heating and defrosting controls shall be located on the front overhead climate control unit. There
shall be additional heating and air conditioning controls located on the engine tunnel mounted climate
control unit.
A/C CONDENSER LOCATION
A roof mounted A/C condenser shall be installed centered on the cab forward of the raised roof against
the slope rise.
A/C COMPRESSOR
The air-conditioning compressor shall be a belt driven, engine mounted, open type compressor that shall
be capable of producing a minimum of 32,000 BTU at 1500 engine RPMs. The compressor shall utilize
R-134A refrigerant and PAG oil.
UNDER CAB INSULATION
The underside of the cab tunnel surrounding the engine shall be lined with multi-layer insulation,
engineered for application inside diesel engine compartments.
The insulation shall act as a noise barrier, absorbing noise thus keeping the decibel level in the cab well
within NFPA recommendations. As an additional benefit, the insulation shall assist in sustaining the
desired temperature within the cab interior.
The engine tunnel insulation shall measure approximately 0.75 inch thick including a vertically lapped
polyester fiber layer, a 1.0 lb/ft² PVC barrier layer, an open cell foam layer, and a moisture and heat
reflective foil facing reinforced with a woven fiberglass layer. The foil surface acts as protection against
moisture and other contaminants. The insulation shall meet or exceed FMVSS 302 flammability test.
The insulation shall be cut precisely to fit each section and sealed for additional heat and sound
deflection. The insulation shall be held in place by 3 mils of acrylic pressure sensitive adhesive and
aluminum pins with hard hat, hold in place fastening heads.
INTERIOR TRIM FLOOR
The floor of the cab shall be covered with a multi-layer mat consisting of 0.25 inch thick sound
absorbing closed cell foam with a 0.06 inch thick non-slip vinyl surface with a pebble grain finish. The
covering shall be held in place by a pressure sensitive adhesive and aluminum trim molding. All
exposed seams shall be sealed with silicone caulk matching the color of the floor mat to reduce the
chance of moisture and debris retention.
