NOTE
For your safety, and for extended product life, use
y
only authorized components. The manufacturer
is not responsible for product malfunction
or accidents caused by the use of separately
purchased unauthorized parts.
Use new hoses when you install the washing
y
machine. Do not reuse old hoses. Use only the
inlet hoses provided with the washer. LG does not
recommend the use of aftermarket hoses.
Periodically check the hoses for cracks, leaks and
y
wear, and replace the hoses every 5 years.
Do not stretch the water hoses intentionally, and
y
make sure that they are not crushed by other
objects.
Water supply pressure must be between 14.5 PSI
y
and 142 PSI (100 – 980 kpa). If the water supply
pressure is more than 142 PSI, a pressure reducing
valve must be installed.
To provide optimum washing performance the hot
y
water temperature should be set at 120-135°F (48-
57°C) and the cold at 60°F (15°C).
