6. REFRIGERANT INSTALLATION

1. Precautions during refrigerant installation.
Use clean pipes with no dust inside.
The pipe may corrode with the presence of fl uorine dust which will adversely affect the refrigerant piping system due to
deterioration of the refrigerant oil, etc.
This unit is specifi cally for R410A. Ensure to adhere to the following
items and install accordingly:
• Use pipe cutters and fl aring tools which are specially designed for
use with R410A.
• When connecting with fl aring tools, coat the fl are section with ether-
based oil.
• Ensure to use fl are nuts supplied with the unit when connecting this
unit.
• Only for storing or for open pipes.
• Set the lower limit of the allowable pipe length to 5m.
If the pipe is shorter than 5m, the refrigerant may become overfi lled
and a problem such as abnormal high pressure could occur.
• Carefully handle the liquid refrigerant, as it may cause a frostbite.
• Do not release refrigerants during the piping works for installing,
re-installing and repairing refrigeration parts.
2. The local pipes can protrude from any four directions.
Make holes in the pipe panel for the pipes to penetrate it and lay the
pipes accordingly.
• It is recommended to apply additional substance to the cut area for
anti-rust protection.
Ensure to install pipe panels to prevent rain water from getting into
the unit.
Close the gap at the pipe connected area with putty or heat insulator
(locally supplied).
• If an insect or small animal enters the outdoor unit, there is the risk
of shorting in the product electronic casing.
