Cautions on pipe handling
• Protect the open end of the pipe from dust and moisture.
• All pipe bends should be as gentle as possible. Use a pipe bender for bending.
Selection of copper and heat insulation materials
When using commercial copper pipes and fittings, observe the following:
• Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.024 to 0.030Btu/fth°F (0.035 to
0.045kcal/mh°C))
Be sure to use insulation that is designed for use with HVAC Systems.
•
ACR Copper only.
• Be sure to insulate both the gas and liquid piping and observe the insulation
dimensions as below.
Be sure to
place a cap.
Wall
Rain
If no flare cap
is available,
cover the flare
mouth with tape
to keep dirt and
water out.

• Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
•
Using finishing tape, bundle and wrap the indoor unit piping and drain hose
together so that the drain hose is below the other piping.

WARNING
•
Make sure that air or any matter other than refrigerant (R32) does not get into the refrigeration cycle.
• If refrigerant gas leaks should occur, ventilate the room as soon and as much as possible.
• R32, as well as other refrigerants, should always be recovered and never be released directly into the environment.
•
Use tools for R32 or R410A (such as the gauge manifold, charging hose, or vacuum pump adapter).
CAUTION
•
It is highly recommended that you do not open/close the stop valves when the outdoor temperature is below −5°F (−21°C)
as this may result in refrigerant leakage.
