9-7. Thermal insulation for pipes
Insulate pipes to prevent condensation.
-Condensation may collect and drip from the unit onto the ceiling or floor.
Insulate the liquid and gas pipes separately with polyethylene foam insulation materials. Inadequate insulation may
cause condensation to drip. Pipes in the ceiling are especially vulnerable to condensation and require adequate
insulation.
9-7-1. Insulation material
・
Check that the insulation materials meet the standards in the table below.
Pipe size [mm (in)]
ø6.35 (ø1/4)–ø25.4 (ø1)
ø28.58 (ø1-1/8)–ø41.28 (ø1–5/8)
Thickness [mm (in)]
Min. 10 (7/16)
Min. 15 (5/8)
Heat resistance
Min. 120°C (248°F)
* The insulation thickness may need to be increased in high-temperature/humidity conditions.
* Even when specifications are defined by your client, the standards in the table should be met.
