2.1 Installations in High Humidity Environments
When the unit is installed in a hot and humid place, if the humidity inside the
installation space exceeds 86℉ and RH 80%, it is recommended to insulate the
cabinet exterior. Use glass wool or polyethylene foam as insulation; the thickness
should be more than 2 in. and it must fi t inside the installation space opening.
Condensation may come from the surface of the insulation. Be sure to use
insulation that is designed for use with HVAC Systems. Condensation may be
produced on surface during cooling operation. It is also recommended to use
