LEFT SIDE DOWN
Horizontal installations with the left side panel down will require drain hoses to be connected to the left side front cover drain port and the side drain port on the rubber elbow.
1.Remove the rubber plug from the front cover left (down) side drain port.
2.Relocate the front cover pressure switch hose connection from the right side (as shipped) pressure tap to the left (down) side tap. The pressure switch hose must be connected to the down side to guard against blocked drain conditions. Cut hose to appropriate length to minimize sagging. Plug right (unused) pressure tap with plug removed from left side.
3.Secure Hose A to front cover drain port with a red hose clamp. Route hose to rear left (down) side panel grommet holes. NOTE: For left side drainage, grommets must be relocated to left side panel.
4.Remove the rubber cap from the side drain port on the rubber elbow.
5.Secure the short end of Hose B to rubber elbow side drain port using a green hose clamp. NOTE: For left side drainage, route hose to far left (down) side panel grommet holes. NOTE: Horizontal left side connections (when using new side port drain elbow) does not require connecting a hose to the induced draft blower housing.
6.Cut 5 1/2 inches straight length from the long end of each Tube 2 and discard radius ends.
7.Insert approximately one inch of each Tube 2 through left side panel grommet hole. Secure tubes to Hose A and Hose B with a green hose clamps. NOTE: Tube must reach bottom of trap. Ensure hoses and tubes maintain a downward slope for proper drainage and that they are not kinked or binding.
For details concerning mounting of the drain trap, refer to Conden- sate Drain Lines and Drain Trap - Horizontal Drain Trap Mounting.

2.Secure drain trap to side panel at the dimples or crosshairs located on either side of the grommet drain holes.
3.Confirm that tubes reach bottom of drain trap and that all hoses maintain a downward slope and are not kinked or binding.
4.Attach PVC drain line to drain trap outlet with either a 90° elbow or coupling.
