Base construction and installation of the outdoor unit
Examples of draining work
Construct the drainage ditch with reinforced concretes and make sure that water-proofing work is done.
For smooth draining of defrost water, make sure to apply 1/50 slope.
Construct a drainage around the outdoor unit to prevent the defrost water (from the outdoor unit) from stagnating,
overflowing or freezing near the installation space.
When the outdoor unit is installed on the roof, check the strength and waterproof status of the roof.
