NOTE:
Relocation of the front cover pressure switch hose
is required 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. The hose must be cut to appropriate length to
minimize sagging.
