CAUTION
Never route refrigerant hose, electrical
cable or drain lines in any location where
driver's visibality would be impaired.
r Follow steps a through c above. The additional 2
inches of cut-out may not be required if there is access
from another source (See Figure 2-50 & Figure 2-52).
In the example shown, the indicator light assembly was
removed which allowed access between the interior and
exterior walls.
CAUTION
When marking the cut-out for a front
mounted In-Wall be very careful not to cut
too much off the top radii.
NOTE
The front metal cover leaves little room for er-
ror. If a cutting error does occur, a metal piece
painted to match the color of the bus interior
must be fabricated and installed to hide the cut-
ting error (See Figure 2-51 and Figure 2-55).
s In this application a hole was cut through the bus
structure rail. This allowed for connection of the
hose/fittings to the block valve (See Figure 2-51).
CAUTION
When removing any electrical item involv-
ing multiple plugs/sockets it is recom-
mended that you mark both sides of the
plug/socket arrangement. This way you will
not have to guess what goes where when
re-connecting.
t In this example the hose was routed from the
passenger side, over the top of the entrance door, over
the top of the IW evaporator and connected to the block
valve. Removal of the indicator light assembly allowed
access for fitting/hose assembly and connection.
NOTE
Refrigerant hose, electrical cable and any bus
wiring must be securely clamped above the IW
evaporator assembly before attempting to
install the In-Wall.
CAUTION
Because of the limited access to the block
valve, start the fittings by hand (finger tight-
ening) making sure that there is no cross-
threading before tightening. When tighten-
T--311
ing the fittings, make sure that the Block
Valve does not move.

Never tie-wrap or secure in any way, refrig-
erant hose or electrical cable to any part
that may move during the normal operation
of the vehicle. Always use insulated clamps
to secure to the bus wall. (See Figure 2-53 &
Figure 2-54)
