• To minimize vibration, do not install the outdoor unit directly on the ground.
Instead, install it on top of a fi rm platform (such as concrete block). (Fig. B)
• The foundation base should be able to support the product and the foot width of
the product should be more than 46.5mm.
• Depending on the installation condition, vibration during the operation of the unit
may cause noise and vibration.
Install vibration-proofi ng materials (such as rubber pads).
• Consider the removal space of the connection piping when installing the founda-
tion.
• Secure the equipment fi rmly with anchor bolts, washers, and nuts.

4. 1. System confi guration
CAUTION
• When connecting multiple outdoor units, set the nearest outdoor unit to the indoor
unit on the refrigerant pipe as the master unit.
• When connecting multiple outdoor units, install the outdoor unit with the largest
nominal system capacity nearest to the indoor unit on the refrigerant pipe, fol-
lowed by those with less nominal system capacities.
[Capacity: Master ≥ Slave]
• Always keep to the limit on the total amount of refrigerant. Exceeding the limit
on the total amount of refrigerant when charging will lead to malfunction.
