CONNECTING REFRIGERANT PIPING LINES - System Model 53KDHT42N-518T
USE OF REFRIGERANT PIPING LINES
The following data refers to the use of refrigerant piping lines of diameters equivalent to that use in
units where : L = Maximum length of refrigerant piping lines between outdoor and indoor units.
H = Maximum vertical distance between outdoor and indoor units.
(A) OUTDOOR UNIT BELOW INDOOR UNIT :
Slop tubing towards the outdoor unit with a fall of at least (6mm) to (305mm).
(B) OUTDOOR UNIT ABOVE INDOOR UNIT :
x
If height is less than or equal 4 meters, one oil trap must be at the suction line at the base of
suction riser near the Indoor unit to facilitate oil return to the compressor to ensure efficiency
of compressor mechanical parts.
x
If height is more than 4 meters, more than one oil trap must exist at the suction line, the first
one will be at the suction line near to the indoor unit and the following one will be 4 meters
from the first one and so on.
(C) OUTDOOR UNIT ON THE SAME LEVEL AS INDOOR UNIT:
An oil trap is preferred to be at the suction line at the base of suction riser near the Indoor unit
to facilitate oil return to the compressor to ensure efficiency of compressor mechanical parts.
