Heater Air Conditioning, Ventilation - Endeavor 
GENERAL DESCRIPTION The heater and cooling units are combined in a single unit, which, with the mode 
film damper and flow rate control valve in the heater unit, reduces ventilation 
resistance, increases fan power, and decreases noise. 
GENERAL SPECIFICATION SAFETY PRECAUTIONS Because R-134a refrigerant is a hydro fluorocarbon (HFC) which contains 
hydrogen atoms in place of chlorine atoms, it will not cause damage to the ozone 
layer. 
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone 
layer, Mitsubishi Motors Corporation recommends an R-134a refrigerant recycling 
device. 
Refrigerant R-134a is transparent and colorless in both the liquid and vapor state. 
Since it has a boiling point of -29.8°C (-21.64°F) at atmospheric pressure, it will be 
a vapor at all normal temperatures and pressures. The vapor is heavier than air, non-
flammable, and non-explosive. The following precautions must be observed when 
handlin
