Please follow this procedure if it is necessary to adust the expansion valve.
First remove the drain box to access the expansion valve. The expansion valve
protrudes through the sheet metal, has the shape of a cylinder, is brass in color
and approximately 25mm in diameter. The valve will be hot, so, using adequate
protection, in order to adjust the expansion valve rotate the valve clockwise
to raise the pressure and counter clockwise to reduce the pressure. It may be
necessary to use a tool such as a pair of pliers to rotate the expansion valve in
1/4 turn or less increments until the desired pressure is achieved. Replace the
drain box after each adjustment to ensure the machine is operating correctly.
