6. Secure remaining end of Hose B to exposed end of Tube 1
with a green hose clamp. Route hose to front right down
side panel grommet holes.
7. Cut 5 1/2 inches straight length from the long end (end with
taper) of each Tube 2. Save the 5 1/2” long pieces and
discard the pieces with the bends.
8. Insert approximately one inch of each Tube 2 through the
right down side panel grommet holes. Secure tubes to
Hose A and Hose B using green hose clamps. Ensure
hoses and tubes maintain a downward slope for proper
drainage and are not kinked or bound.
9. A “Blocked Drain Kit” MUST be installed for right side down
installations. The kit includes a front cover pressure switch
that must be used to protect against a blocked drain
condition. Install the front cover pressure switch per the
instructions included with the “Blocked Drain Kit”. Failure to
install the “Blocked Drain Kit” will void the warranty and could
lead to bodily injury or death.
For details concerning mounting of the drain trap, refer to Section
