Pipe Insulation - Samsung AM MXVAFC Series Installation Manual

Pipe insulation

Insulating the refrigerant pipes and branch joints
f Check for gas leakage before completing (the hose and pipe insulation) and if there is no sign of leakage, make sure to f
insulate the pipes and hoses .
f Use EPDM material insulator that meets the following conditions . f

Selecting the refrigerant pipe insulator
f Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size . f
f The standard condition is; temperature at 30°C, humidity less than 85% . If case if the humidity is higher, you must f
increase the size by one grade as stated in below table .

❋ ❋ When installing insulation in places and conditions below, use the same insulation that is used for high humidity
conditions .
<Geological condition>
- High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is
covered by earth and sand . )
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc .
<Building construction condition>
- The ceiling frequently exposed to moisture and cooling is not covered . (e . g . The pipe installed at a corridor of a
dormitory and studio or near an exit that opens and closes frequently . " )
- The place where the pipe is installed is highly humid due to the lack of ventilation system .
