After finishing the charging procedure, the piping must be insulated. Take into

account the following points:

▪ Be sure to insulate the liquid and gas piping (for all units).

▪ Use heat resistant polyethylene foam which can withstand a temperature of 70°C

for liquid piping and polyethylene foam which can withstand a temperature of

120°C for gas piping.

▪ Reinforce the insulation on the refrigerant piping according to the installation

environment.
