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.
