2.1.4 Base structures
Outdoor unit base structure design should take account of the following considerations:
 A solid base prevents excess vibration and noise. Outdoor unit bases should be constructed on solid ground or on
structures of sufficient strength to support the units' weight.
 Bases should be at least 200mm high to provide sufficient access for installation of piping.
 Either steel or concrete bases may be suitable.
 A typical concrete base design is shown in Figure 3-2.6. A typical concrete specification is 1 part cement, 2 parts sand
and 4 parts crushed stone with Φ10mm steel reinforcing bar. The edges of the base should be chamfered.
 To ensure that all contact points are equally secure, bases should be completely level. Base design should ensure that
the points on the units' bases designed for weight-bearing support are fully supported. Bolt spacings should be as per
Figure 3-2.7 and Table 3-2.2.
 A drainage ditch should be provided to allow drainage of condensate that may form on the heat exchangers when the
units are running in heating 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.
