D. FINAL ASSEMBLY AND CHECK. 1. Reinstall fresh air-intake hose, glove box and center dash panel. 2. Connect the batteries. 3. Evacuate the system, test for leaks and charge with R-12 refrigerant. (R-134a for R-2110-19) 4. Turn the ignition switch to the "on" position, place the fan speed switch on high. a. The clutch should click on and be engaged. If not, see step #8. b. The evaporator blower should be turning at high speed. 5. Turn the fan speed switch to medium and low positions and check that the evaporator blower slows down. 6. Turn the fan speed switch to the "off" position and check that the compressor clutch disengages. 7. Start engine and run at 1500-2000 RPM. Turn fan speed switch to high. Check sight glass on receiver drier for bubbles. Add 6 to 8 ounces more R-12 after the sight glass clears. Note: Be aware that the sight glass may appear "milky" when charging with R-134a. Be careful not to overcharge the system. 8. Make sure clutch cycles on and off as system is operating. Note: If clutch does not engage, the system may not have been charged to a high enough pressure to actuate the trinary switch. Place a jumper wire across the switch and run system until it is fully charged then remove jumper wire. 9. Fill out service label properly and adhere in prominent location. Red Dot Corporation P.O.
