Refrigerant Piping
• Piping kit used for the conventional refrigerant cannot be used.
• Use copper pipe with 0.8 mm or more thickness for Ø 6.4, Ø 9.52,
Ø 12.7.
Outdoor unit Protective bush
Installation manual x 1 (For SM800AT only)
Drain nipple Guard material for passage
Waterproof rubber cap part (For SM800AT only)
NOTES: Caution at addition of refrigerant
(1)
When the total length of refrigerant pipe exceeds 20m, add 20g/m. The pipe total maximum length is 30 m. (Max. amount of additional refrigerant is 200g.).
Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor.
(2)
When the total length of refrigerant pipe exceeds 20m, add 40g/m. The pipe total maximum length is 50 m. (Max. amount of additional refrigerant is
1200g.). Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor.

Refrigerant addition
.
20 m o shorter: for all units Do not add refrigerant at installation site
(1)
from 20 m to 30 m (38VYX 050) Add 20 g of refrigerant for every meter of pipe beyond 20 m
(2)
from 20 m to 50 m (38VYX 080) Add 40 g of refrigerant for every meter of pipe beyond 20 m
Use copper pipe with 1.0 mm or more thickness for Ø 15.87.
• Flare nut and flare works are also different from those of the
conventional refrigerant.
Take out the flare nut attached to the main unit of the air
conditioner, and use it.

eliminate ice that might possibly collect on the outdoor unit in very low
ambient temperatures.
In these cycles, fan speed will automatically reduce and cannot be
varied until defrost cycle is completed.
