Pipe Insulation

After finishing the leak test and vacuum drying, the piping must be insulated. Take into account the
following points:
Make sure to insulate the connection piping and refrigerant branch kits entirely.
Make sure to insulate the gas side connection piping and refrigerant branch kits entirely against heat,
and depending on operation conditions (e.g. when performing cooling operation with an outside air
temperature of ≤15°C), consider to also make a heat insulation of the liquid side connection piping and
refrigerant branch kits to prevent dewing.
Use heat resistant polyethylene foam which can withstand a temperature of 70°C for liquid side piping
and polyethylene foam which can withstand a temperature of 120°C for gas side piping.
Caution Be sure to insulate local pipes, as touching them can cause burns.
