1. Precautions during refrigerant installation.
•
Use clean pipes with no dust inside.
The pipe may corrode with the presence of fluorine dust which will adversely affect the refrigerant piping
system due to deterioration of the refrigerant oil, etc.
•
This unit is specifically for R410A. Ensure to adhere to the following items and install accordingly:
•
Use pipe cutters and flaring tools which are specially designed for use with R410A.
•
When connecting with flaring tools, coat the flare section with ether-based oil.
•
Ensure to use the flare nuts supplied with the unit when connecting this unit.
•
Only for storing or for open pipes.
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.
[Remove the front panel]
(1) Remove the 2 mounting screws.
(2) Slide the front panel using your hands
downwards to release the pawls.
Then remove by pulling the panel
towards you.
Precautions when operating the 3-way valve for piping installation
•
Do not open the 3-way valve until all air flow parts are completed.
•
It is closed during shipment.
•
During installation the side panel may warp if only the flare nut is loosened and tightened with a torque
wrench. As a result, always be sure to secure to the hexagonal part of the 3-way valve with a spanner, or
other tool.
•
Refer to the following table for the tightening torque of the 3-way valve flare nuts.
•
If the nuts are over tightened, they may cause the flares to break or leak.
•
Do not add additional force to the valve’s cover.
•
Using spanners on the cover or valve itself (other than the hexagonal parts) may cause gas leakage.
Avoid using spanners on the cover or parts other than the hexagonal part of the valve.
