COUPLINGS to eliminate the possibility of
intermixing the circuits when the intercon-
necting tubing is installed. The suction and
discharge lines in the evaporator section will
now be dangling, so be careful you don’t dam-
age the tubing connections. Do not discon-
nect the male half of the self-sealing couplings
(Item , Figure 12), which are still attached
to the bulkhead of the condensing section.
3. Remove the unit top tie piece* (Item , Figures
5, 6 & 7, pages 6 & 7), removing only those
screws which attach the top piece to the two top
panels. (*If unit is already shipped split, these are
not included.)
4. Remove control box access panels from the
evaporator section (Item , Figure 5), and the
condensing section (Item , Figure 5), by remov-
ing the screws at the top and bottom of each ac-
cess panel.
5. Disconnect and discard the wires which run be-
tween the two internal control boxes (Item ,
Figure 7). Single circuit units will have two low

For single circuit, use one kit; for dual circuits, use two kits; for triple circuits, use 3 kits.
2 Interconnect kits for 1 and 1-1/2 Ton units are the same as kits for other tonnage except for the self-sealing couplings on the suction line,
which are part number 6CA1005 for the female half, and 6CA1006 for the male half.
