Functional Test Procedures1. Place transmission in park for automatics and in
neutral for manuals. Apply hand brake.
2. Turn blower switch to HI position,
3. Turn temperature switch to MAX position-.
4. Run engine at 2000 RPM for ten (10) minutes with
car doors and windows closed and the hood up. Place
a commercial high volumn fan in front of condenser
if head pressure should exceed 250 psig.A commercial high volumn fan should be placed in
front of the condenser at high ambients to bring the
pressures to within the limits specified in the Func-
tional Charts. When testing the Opel 1900 and
Man& a thermometer should be placed in a position
to read the temperature of the air discharging from
the right-hand A/C outlet. When testing the GT, a
thermometer should be placed in a position to read
the temperature of the air discharging, from the left-
rear
,A /c outlet.
