Cabinet Weatherproofing
This unit ships from the factory with fully gasketed access
doors and cabinet caulking to provide weatherproof opera-
tion. After the unit has been set in place, inspect all door gas-
kets for shipping damage and replace if necessary.
It is recommended the unit be protected from overhead water
run-off from overhangs or other structures. Re-caulk field
assembled options, such as external piping vestibules or split
units, per installation instructions provided with the option.
