2.  Cut out center section.  Install one cabinet retaining clip in 

each of the two top holes to assist holding cabinet while 
installing six cabinet screws.  Install drain pan, evaporator 
pad and distributor trough using thumb nuts provided.

water pipe.  A side or top mount is best to avoid clogging from

Copper tubing requires a brass compression nut and brass 
sleeve.  Plastic tubing requires a brass insert inside the tubing, 
a plastic sleeve on the outside with a brass compression nut.
