condensate prevention and heat insulation properly. 
  If it is forecast that high humidity and temperature environment (condensate temperature is over 
23°C) may exist in the ceiling, e.g., inside the ceiling with slab, (ceiling which is in the same 
environment  as  the  outdoor  air),  it  is  necessary  to  apply  10mm  or  thicker  adiabatic  wool 
(16~20kg/m
2
) to the refrigerant pipe and the drain pipe in addition to apply the general heat 
insulation materials. Enough heat insulation materials should also be applied to the refrigerant 
joint and the pipe joint. 
  The drain of water is natural. In the construction, the external pipe slants downward at a gradient 
of 1/50~1/100. 
  The number of bends and folds of the drain pipe should not exceed 2. Try to avoid bends in 
order to prevent trash accumulation. Furthermore, to reduce the depositing dust, avoid bending 
the pipe as possible. 
 
  Open the side panel of indoor unit to charge water into water collection tray, after the drain water 
pipe is installed, check whether the water can be drained smoothly and whether the joints are 
leakage. 
  After making sure that the water drains smoothly and no water is leaked, use a diabatic wool 
bushes to preserve heat of the drain pipe. Otherwise, condensate will occur.

  For ensure the proper installation, first select the enough solid and level site. 
  Ensure enough space required for installation and maintenance.
