Mechanical Installation
• Removing limiting piece of the electrical control box
The electrical control box may move during transportation. To prevent this abrupt movement, a limiting piece of
the electrical control box is installed before delivery. The limiting piece has to be removed before operating the
unit so that the maintenance personnel can slide out the electrical control box during maintenance.
• Adjusting the supply air bale
Adjust the installation direction of the supply air bale to lead wind to the left or right depending on the
installation location of the Liebert® CRV4 series air conditioners. The supply air bale is composed of several
pieces. Remove the screws on both sides of the single piece of the supply air bale, rotate it by 180°, then Install
it back to change the wind direction. Figure 3-23 shows the location of the mounting screws of a single piece of
the supply air bale.
