Horizontal - Carrier 59SP5A Installation, Start-Up, Operating And Service And Maintenance Instructions

NOTE: The condensate trap extends below the side of the casing
in the horizontal position. A minimum of 2 in. (51 mm) of
clearance is required between the casing side and the furnace
platform for the trap to extend out of the casing in the horizontal
position.
To Relocate the Condensate Trap:
S Remove the knockout in the casing for the Casing Grommet.
S Install the grommet in the casing.
S Orient the furnace in the desired position.
S Allow for 2 in. (51 mm) of clearance underneath the furnace for
the condensate trap and drain line.
S Fig. 10 shows the condensate trap and tubing before and after
relocation in the horizontal right position.
S Fig. 11 shows the condensate trap and tubing before and after
relocation in the horizontal left position.
S Refer to the appropriate figure to begin the trap conversion.
S Remove the relief tube from the condensate trap.
S Remove the screw that secures the condensate trap to the
collector box.
S Remove the trap.
S Remove the relief tube from the port on the collector box. It is
not necessary to remove the tube from the inducer assembly.
For Horizontal Left only:
S Remove the pressure switch tube from the front pressure switch
and discard the tube. A new pressure switch tube is shipped in
the loose parts bag.

For Horizontal Right only:
S The pressure switch tube location is not modified.
S Loosen the clamp around the inlet of the vent elbow on the
inducer.
S Remove the plugs from the collector box and set aside. Do Not
Discard Plugs.
For Horizontal Left only:
S Remove the middle and right plug from the ports at the bottom
of the collector box.
For Horizontal Right only:
S Remove the plug to the right of the condensate trap.
S Refer to the appropriate figure to begin the trap conversion.
S Install the plugs previously removed from the collector box in
the ports where the condensate trap was removed.
S Install the trap over the ports on the lower side of the collector
box.
S Secure the trap to the collector box with the screw.
S Connect the relief tube to the condensate trap to the relief port of
the condensate trap.
S If necessary, slide the relief tube in the inducer stand-offs to
adjust the position of the tube.
S Connect the relief tube to the relief port of the condensate trap.
For Horizontal Left only:
S Connect the new pressure switch tube to the port on the front
pressure switch. Route the tube through the stand-offs on the
inducer assembly and connect to the port on the collector box.
Trim off any excess tube to avoid sags or kinks in the tube.
S Rotate the vent elbow to the desired position and tighten the
clamp 15 in.-lbs.
S Refer to Condensate Drain section for information how to install
the condensate drain.
