UNITS INSTALLATION
10.2. FAN PERFORMANCE CURVE
RASC unit could be installed using ducts at inlet and outlet air.
Refer to fan performance curve, in order to ensure that the air volume is within working range.
It's assumed that unit will be installed using supply and return air ducts. Find below fan performance curve to decide which ducts are
suitable
RASC-3HVRNE
Air flow (m³/min)
"●" Nominal Point
NOTE:
When design a duct, check to ensure that the Air volume is within working range as indicate "Fan Performance Curve".
-
If the Air volume is set outside working range, water-carry-over (drop in the ceiling or into the room), noise increases, fan

motor damaged (high temperature), insufficient Cooling/Heating capacity, phenomena may occur.
Therefore design ducts and select the correct fan speed in order to keep the unit running in the accepted working range

selected.
10.3. DUCT CONNECTION
Install the duct with down slope to prevent entry of rain water. Also, provide insulation for duct and connection in order to prevent
dew formation.
