3.4.2 Insulating the ducts
CAUTION
To prevent dew condensation, insulate the ducts and pipe
guide. (glass wool 25 mm or equivalent)
Make sure to insulate up to the base of pipe guide.
When the Lossnay is anticipated to be stopped for a long
time, insulate the RA (Return Air) side ducts also. (i.e. not
operated for 24 hours).
Indoor humidity can cause condensation because exposed
parts can become cold in winter.
