2.8 Drainage
Drainage ditch should be provided to allow drainage of condensate that may form on the air side heat exchanger when
the unit is running in heating mode or domestic hot water mode. The drainage should ensure that condensate is directed
away from roadways and footpaths, especially in locations where the climate is such that condensate may freeze.

2.9 Spacing
Outdoor units must be spaced such that sufficient air may flow through each unit. Sufficient airflow across heat
exchangers is essential for outdoor units to function properly. For more details please refer to the figures below.
