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.
