8. USING A VIBRATION-RESISTANT FRAME

 A vibration-reduction frame must be used if the unit is installed in locations where noise and vibration can
be a problem, such as on rooftops above living spaces or conference rooms. If a vibration-resistant frame
is used, be sure to install steady braces or other support, and take measures to prevent applying excessive
force to the refrigerant tubing.
 Refer to the instruction manual supplied with the vibration-resistant frame when installing the frame.
(1) When Using Singular Frames
 When anchoring the refrigerant tubing, be sure to set the tubing anchor for each outdoor unit at least 1.5 m
away from the respective unit (as shown in Fig. 24-1).
 When installing a ball valve, be sure to install them within area B. (Installation in area A is prohibited.)

CAUTION
When using single-type vibration-
resistant frames, never install tubing in
the manner shown at the right. Doing so
puts excessive weight on the entire tubing
installation and may result tube damage.
