Refrigerant Pipe Work - Samsung AC Series Installation Manual

Refrigerant pipe work

Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
1. To avoid condensation problems, place an insulator around each refrigerant
pipe.
• When insulate the pipe, be sure to overlap the insulation.
• The insulation has to be produced in full compliance of European regulation reg.
NOTE
EEC / EU 2037/ 2000 that requires the use of sheaths insulation form without using
CFC and HCFC gases for health and the environment.
• When insulating the pipe, use non-slit insulator.
CAUTION
2. Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness according
to the pipe size.
Less than Indoor temperature of 30°C and humidity of 85% is the standard
condition. If installing in a high humidity condition, use one grade thicker
insulator by referring to the table below. If installing in an unfavorable
conditions, use thicker one.
Insulator's heat-resistance temperature should be more than 120°C.

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.
