COOLING
A. Overhead Vent System.
When the optional air conditioning system is not installed cabin ventilation and cooling is provided by
fuselage and is ducted through overhead ducting to the cabin. Air flow is controlled by a flapper valve
positioned in the duct just forward of F.S. 220. A CABIN AIR control knob, located in the cockpit
overhead duct, positions the flapper valve to allow fresh air to enter the cabin or to stop the flow of air.
(1) Optional Overhead Vent Blower
An optional blower will force air through the overhead vent system whenever desired. It is
mounted aft of the close-out panel underneath the top of the fuselage and is connected to the
overhead vent system. The vent blower draws air in from the left rear side of the fuselage and
forces it through the ducting. A three position blower switch on the instrument panel controls the
two speed blower.
(2) Removal of Vent Blower Assembly.
(a) Remove the access door from the aft wall of the baggage area.
(b) With the master switch off, disconnect the plug assemblies at the blower assembly.
(c) Remove the inlet and outlet hoses from the blower assembly by removing the clamps.
(d) Remove the screws, washers and nuts that secure the blower assembly to the hanger braces.
(e) Remove the screws and washers which secure the blower assembly to the retainer and
hangers.
(f) Remove the blower assembly from the aircraft.
(3) Disassembly of Vent Blower
(a) Remove the hose duct from the forward edge of the blower assembly by removing the nuts,
washers and screws.
(b) Remove the cover from the blower assembly by removing the nuts, washers and screws.
(c) Remove the blower fan from the motor shaft by removing the set screw.
(d) For removal of the motor, proceed as follows:
1 Separate the plate from the motor cover by carefully drilling out the connecting rivets.
2 Cut the motor wires at the edge of the receptacle and plug and remove the wire ends
from the blocks.
3 Remove the motor from the mounting plate by removing the nuts, washers and bolts.
(4) Assembling Vent Blower
(a) Mount motor on plate and secure with bolts, washers, and nuts. Check that motor nuts are
snug and shaft spins freely.
(b) Position cover over motor plate with motor wires protruding through cover grommet.
(c) With holes in cover matching holes in motor plate, secure the two parts together with rivets.
(d) Fill any opening left where wires are pass through cover grommet with PRC-5000 sealant.
(e) Install wires in plug and receptacle.
(f) Position blower fan on motor shaft and secure with set screw.
(g) Position hose duct on blower assembly and secure with screws, washers, and nuts. Install
screws with heads
inside
duct.
(h) Clean old sealant from all surfaces where duct attaches to blower assembly.
(i) Seal all surfaces where duct attaches to blower assembly with PRC-5000 white rubber
caulking.
