Installation Of Outdoor Unit; Refrigerant Piping Work - Acson international B Serie Manual De Instalación

Air intake grille installation
• Before installing the air intake grille, be sure to fix the
ionizer filter to the air filter.
• Install the air intake grille together with the air filter to the
front panel.
• The grille can be fit in any direction, when selecting
direction, the ceiling design and grille operability should
be considered.
• If the unit comes with ionizer filter (optional item), make
sure to fix the ionizer filter to the air filter before installing
the air intake grille.
• Fix the ionizer filter to the air filter with the black side on
top and white side at bottom.
• Carefully clip on the ionizer filter frame.
Preliminary site survey
• A place protected from rain, direct sunlight and well-ventilated wherever practicable.
• A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
• A place where there are no obstruction of air flow into or out the unit.
• Do not put any object which may become obstacle for the air flow into or out the outdoor unit.
• The location must not be susceptible to high concentration dust, oil, salt or sulfide gas.
Outdoor unit installation
• Install the outdoor unit firmly and horizontally. Maintain a space clearance from the obstruction as shown in below for
servicing and air ventilation.
A B
Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized
by the perfect piping work.
Piping length and elevation
If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to
flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective.
Always choose the shortest path and follow the recommendation as tabulated below.
