2. PS310/360-series contactor replacement
Remove the two Phillips-head screws holding the
cover in place. Then, remove the cover.
Remove the six terminal lug screws. This proce-
dure must be followed when replacing the coil or
any one contact tube.
The coil and contact tubes will now pull straight
out from the base. The coil or any individual con-
tact tube can now be replaced.
NOTE: When replacing the mercury contactor into
the oven, the wider tube ends must be pointing UP.
The tubes must ALWAYS be mounted in a vertical
position.
Replace the cover and attach it with the two Phillips-
head screws. Note that the cover and base are
marked to show correct orientation.
