install in a location where at least two sides are unob- structed, so that the flow of air at the intake port or exhaust port is not blocked, and so that sufficient space is ensured for maintenance to be carried out without trouble. In general the top also must be unob- structed. (Fig. 5b)

provide a solid base (level concrete pad, concrete block, 6"  1'4" (15  40 cm) beams or equal), a minimum of 6" (15 cm) above ground level to reduce humidity and protect the unit against possible water damage and decreased service life. (Figs. 5c and 5d)

It is recommended to use baffle plates.

When the outdoor unit is installed in a position exposed to strong wind (such as seasonal winds with low air tempera- ture in winter), baffle plates must be installed on the outdoor unit. (Fig. 5f)

This unit is designed so that the fan of the outdoor unit runs at low speed when the air conditioner is operated at low outdoor air temperatures. When the outdoor unit is exposed to strong wind, the system pressure drops because of the freeze protector.

Install a pair of windbaffle plates at the front and back of the outdoor unit if it will be subject to strong wind during the winter. (Figs. 5f, 5g, 5h, 5i, and 5j)
