(8) Remove the terminal block cover and disconnect the wires (two for the heater and four for
the temperature sensor) connected to the component from the terminal block.
(9) Remove the fi ttings and nuts from IN and OUT pipes for carrier gas in the isothermal oven.
(10) Remove the cover or insulator attached to LSV, if any.
(11) Remove the six couplings connected to the LSV. When removing the couplings, label them
for ease of identifying the connections later.
(12) Remove the four screws which fi x the LSV to the outside of the isothermal oven.
(13) Install a new LSV.
(14) Reconnect the pipes in the reverse order of step (7) and (12). Confi rm the wiring and
perform a leak test on the piping.
