5. AFTER INSTALLATION IS COMPLETED
Record the actual length of refrigerant tubing and the amount of refrigerant charge.
With the outdoor unit, the “label for showing the actual length of refrigerant tubing and the amount of
refrigerant charged” is provided. Enter the details in the designated spaces, and apply the label to the
inside of the electrical box panel, at the top.
This will be needed for subsequent maintenance.
Be sure to enter this information and apply the label.
6. ENGINE REPLACEMENT PATHWAY
During installation, consider the engine external dimensions listed at right and ensure that there is a
suf
fi
cient pathway for moving the engine.
This pathway will be required should the engine need to be replaced.

7. 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. 21-1).
When installing a ball valve, be sure to install them within area B. (Installation in area A is prohibited.)
