REFRIGERANT PIPING

INSTALLATION CLEARANCE

Maximum Pipe Length

When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system

piping resistance to the refrigerant Á ow increases, thus lowering the cooling capacity. As a result, compressor reliability will

be affected. Always choose the shortest path and follow the recommendation as tabulated below:

Remark : For FDM60JEVLK cooling unit, recommended to add 6 kg external accumulator

• Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air Á ow. Select

the coolest possible place where intake air should not be hotter than the outside temperature (refer to operating range).
