Maintaining Your GC
• If you are using a cooling tower, grasp the three rings and
unscrew. The spring and duckbill septum may pop out of
the inlet when you remove the cooling tower. Be careful
not to lose them. If they do not pop out, use a thin wire to
remove them from the inlet. Insert the replacement
duckbill septum into the spring and place in the inlet.
Reattach the cooling tower assembly, then finger-tighten.
