SELECTION OF PIPE HEAT INSULATING MATERIAL2-4.
Always insulate the refrigerant pipe to prevent condensation and water droplets by the refrigerant 
pipe.
Decide the thickness of the heat insulating material by referring to the recommended minimum 

When the outdoor unit is installed in a higher position than the indoor unit, fill the connecting part

gap with putty, etc. to prevent the dew condensation water of the valve of the outdoor unit from
flowing to the indoors from the gap between the pipe and the heat insulating material.
Liquid pipe and gas pipe should be completely insulated with same specification.

In case not to insulate and not to seal refrigerant pipe completely, it will become the cause of 
water leak.

When an ambient temperature and relative humidity exceed 32°C DB and 85% respectively,

please strengthen heat insulation of refrigerant pipe. If necessary put a heat insulation on indoor
unit casing. When not strengthening heat insulation of refrigerant pipe, the surface of the heat
insulation may be dewed.
Since gas pipe becomes high temperature at heating operation for heatpump type, please select

the heat insulating material which heat-resistant temperature is 120°C or more.

Make sure that pipe is covered completely by the heat insulation,not exposing to air. Inadequate 
heat insulation may cause condensation.
Do not cover heat insulation gas and liquid pipes together as above figure. It may cause 
condensation and capacity drop by heat loss.
