Note: Upon reassembly, the references made on
Figures 11 and 12 shall be used for proper
reassembly. The assemblies shall be
secured with wire ties in order to prevent

pan (notched end), a silicone or perma-gum
sealant is adequate. Do not use solvent
base sealers that would harm the ABS
plastic drain pan.
