NOTE: After making the connection, switch

the XEV controller OFF and ON to make sure

that the valve is positioned properly.

NOTE: The electrical power absorption of the

valve can be unrelated to refrigeration power

that the valve has. Before using the actuator,

read the technical manual of the valve supplied

by the manufacturer and check the maximum current

used to drive the valve to verify that they are lower than

indicated below in Table 5-1.
