2 . SELECTING INSTALLATION SITE
Consider the following requirements when choosing the installation location and obtain the cus-
tomer's consent:
• The location must be able to withstand the weight of the Branch Selector unit.
• The location must allow inspection holes to be installed on the control box side. (A separate opening is
necessary when lowering the product.)
• There must be adequate space in which to perform installation and service work. (Refer to Fig . 2 .)
• The length of pipe to the indoor unit and outdoor unit must be less than or equal to the permissible
pipe length (as listed in the installation manual included with the outdoor unit).
• Refrigerant circulated through the pipes can generate sound. Ensure that the installation takes neces-
sary precautions when installing in a sound sensitive applications.
