8. INSTALLATION INSTRUCTIONS

Wind Shield for "CL" Model

IMPORTANT

It is recommended to use wind shields for "CL" model (Fig. 5b). "CL" model is designed to use in low outdoor temperature conditions.

General

When the outdoor unit is installed in a position exposed to strong wind (like seasonal winds with low air tempera- ture in winter), a suitable wind shield must be installed on the outdoor unit.

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.

For outer dimensions of the wind shield, see Fig. 5c.
