The refrigerator must be located where a water supply can be connected for the automatic icemaker.
The water pressure must be 20 - 120 psi or 138 - 827 kPa or 1.4 - 8.4 kgf/cm2. If the refrigerator is installed in an area with low water pressure (below 20 psi or 138 kPa or 1.4 kgf/cm2), you can install a booster pump to compensate for the low pressure.
