Air Conditioner & Heater Controls - Monaco 2002 Diplomat Service Manual

"MAC" valve, receives air pressure from the front air tank. The "MAC" valve
will direct the air pressure to either side of the dual action air cylinder, moving
the stepwell cover in or out. The stepwell cover will not operate without suffi-
cient air pressure (approx. 60 psi).
WARNING: Stepwell cover is under air pressure. When
operating the stepwell cover be sure there are no pets, shoes
or other obstructions in the stepwell area. Do not operate the
stepwell cover while standing in the stepwell area.
Dash AC and Heater Control: The system is designed to only provide
heating, cooling and defrost capabilities for the pilot/co-pilot area. The system
is not capable of heating or cooling the entire motorhome.
Blower Operation: The blower is selected automatically when the desired
feature is selected with the "select switch." The system is shut off by placing
the mode control switch in the "OFF" position.
A/C Operation: The A/C dash system will operate in all modes except
VENT, FLOOR and OFF. The A/C and MAX positions engage the A/C com-
pressor. When the switch is positioned in the A/C mode fresh air is drawn
through the front air intake of the unit through the A/C coil. In the MAX posi-
tion a damper door closes off the fresh air, while another door opens to permit
only air from inside the coach to be used. When maximum cold air is desired
this position should be selected. Also use this position when you do not wish
to introduce outside air into the coach.
Air Distribution Switch (Mode Control):Used to direct air where it is
needed to maximize the comfort of the motorhome.
MAX A/C - Recirculated air is drawn from the passenger
area and discharged through the dash louvers.
A/C - Fresh Air is drawn from outside into the system and
discharged through the dash louvers.
VENT - Fresh air is drawn in and discharged throughout the
dash and defrost louvers.
OFF - The blower motor does not operate. The fresh air inlet door will
close, minimizing outside air infiltration into the motorhome.
