INSTRUCTIONS
IMPORTANT:
When
soldering to the ceramic strips, use the
silver-bearing
solder supplied with this kit.
(
)
1.
Remove the air
filter from the rear of the instrument.
( )
2. Remove the six screws which hold the fan ring to the rear panel and move the fan
assembly
to one side. Do not unsolder the
two fan motor leads.
(
)
3.
Unsolder all the wires from the selenium rectifier stacks, SR241 and SR620, located
behind
the fan motor.
(
)
Unsolder the
two
wires from the thermal
cutout, mounted on the selenium rectifier
bracket.
(
)
4.
Remove the selenium rectifiers and brackets from the instrument.
NOTE:
One
of the nuts holding
a
bracket to the
chassis is under the
high voltage
shield
and can be removed with the use
of
a
needle-nose
pliers.
( )
5.
Remove
the thermal cutout
from
the selenium rectifier bracket and install it on the
silicon rectifier bracket (from kit),
using the 4-40 x 1/4 thread-forming screws
from the kit.
NOTE:
Mount the solder lug between the screw head and the
thermal
cutout (see
Fig 1,
step
5).
(
)
6. Mount the silicon rectifier
assembly (from kit), as shown in Fig 1. Use the
6-32 x 5/16 PHS screws
and #6 flat washers (from kit), placing
a
flat washer under
each screw
head. (Insert screws from bottom
of chassis.)
