Antifreeze Solution and Rust Prevention
• Failure to use antifreeze solution can cause damage to the surrounding devices and pipes due to freezing
and rust.
• Antifreeze solution is injected to preventing freezing of the circulating water of this system. Be sure to inject
pure antifreeze solution for preventing rust and freezing.
• Set this antifreeze solution to a concentration of 35% to 55% for fully realizing the solution's freezing
prevention and rust prevention effects. Dilute using tap water (treated water) that meets the water quality
standards.
• Use a concentration for the antifreeze solution that is 10°C lower than the annual minimum outdoor
temperature.

6. 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.

7. ENGINE REPLACEMENT PATHWAY

 During installation, consider the engine external dimensions listed at right and ensure that there is a
sufficient pathway for moving the engine.
This pathway will be required should the engine need to be replaced.

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