4 Provide an adequate drainage around the foundation. When
installing the unit on a roof or a veranda, drain water may
turn to ice in a cold morning. Therefore, avoid draining in an
area where people often use because it is slippery. In case of
installing such a place, provide the additional drainage around
the foundation.
