3.6 KR2 & KR3
The Carrier Transport
condensers are designed to be installed on the roof of
the bus.
To install the KR2/3 rooftop condensers utilize the
following installation procedures:
a. Select a location on the bus roof where the condens-
er mounting channels will span at least two roof
bows.
The ideal location will be close to the evaporator
inside the bus as well as spanning two roof
bows.
b. Remove the rooftop condenser from the shipping
box.
There are various styles of KR2/3 condenser
mounting brackets that are available to fit the
different contours of a bus roofs. There are also
different style feed-thru plates available de-
pending upon if you are installing side mounted
or rear mounted evaporators. Make sure you
have the correct mounting brackets and/or
feed-thru plates befor proceeding with the
installation. Refer to T--299PL Service Parts
Manual for available plate configurations.

c. Remove rooftop cover from unit and place condens-
er on the center (side to side) of the bus roof at the
predetermined location.
d. Install the KR2/3 Rooftop Condenser assembly fol-
lowing steps h. or i. in Section 3.5. Some applications
will allow the use of bolts through the bus roof and
ceiling.
e. Mark where the feed-thru plate will be located and
cut-out so the feed-thru plate fittings will drop
through the opening.
If connecting to a rear mounted evaporator, in
most cases the cut out will be through both the
bus roof and ceiling. If side mounted evapora-
tors, the cut out will only be through the bus
roof.
f. Connect the condenser liquid and suction line as-
semblies to the feed-thru plate.
g. Push the condenser electrical harness through the
feed-thru plate tube. Seal around the opening.
h. After connecting refrigerant lines and condenser har-
ness(s) install the condenser cover with hardware
provided.
i. Clean condenser cover with a mild cleaning solution
and clear all debris from the roof of the bus.
