determines the integrity and safety of the unit.
Please check the equipment model number to ensure the unit is appropriately
sized for the condensing unit.

supplier. The manufacturer assumes no responsibility for the installation of incorrectly

When installing the air handler, take consideration to minimize the length of
refrigerant tubing as much as possible. Do not install the air handler in a location either

elevate the unit with a sturdy, non-porous material. In installations that may lead to
physical damage (i.e. a garage) it is advised to install a protective barrier to prevent
such damage.
