NOTES
(Locally procured)
1 Leave space for servicing the unit and include inspection hatch.
(Always open a hole on the side of the control box so that the air
filters, heat exchange elements, and fans can easily be inspected
Heat insulator
and serviced.)
(Locally procured)
2 Install the two outdoor ducts with down slope (slope of 1/30 or more)
to prevent entry of rain water, also, provide insulation for three ducts
(outdoor ducts and indoor supply air duct) to prevent dew
condensation) (material: glass wool of 25mm thick).
Air discharge grille
3 Do not turn the unit upside down.
(Locally procured)
4 Make sure install drain piping, and insulate drain piping to prevent
dew condensation.
5 Keep the drain pipe short and sloping downwards at a gradient of at
least 1/100 to prevent air from forming.
6 Do not use a bent cap or a round hood as the outdoor hood if they
might get rained on directly (we recommend using a deep hood)
(optional accessory).
7 In areas where freezing may occur, always take steps to prevent the
pipes from freezing.
8 Do not place something which shouldn't be get wet at the below of
this unit. The dew would fall at following case, where humidity is 80%
more, or the exit of drain socket is choked up, or the air filter is very
dirty.
