6.2.5 Cleaning of pump
For the pump case / disassembled nozzles and gaskets, clean them with alcohol.
(1) Wear clean nylon gloves to avoid touching by bare hands.
(2) Be sure to be in a well-ventilated place when cleaning the nozzle.
(3) If the vacuum piping with the pump removed is dirty, clean it too.
6.2.6 Assembling of nozzle
Assemble the nozzles in reference to Figs. 10 to 13 in the reverse order of disassembling of the
nozzles. However, pay attention to the following:
For ULK-04A,ULK-06A
When inserting the nozzles into the pump case,
set them so that the four set screws on the fixing ring are inserted into the outermost notches on
the nozzles.
At this point, set them so that the ejector nozzle is positioned on the air outlet side.
For ULK-10A,ULK-14A
(1) Set the notches at the lower part of the 5th steam cylinder
(25)
, 4th steam cylinder
㉒
, and
3rd steam cylinder
㉑
to be perpendicular to the air outlet port of the pump case
⑧
.
(2) Do not excessively tighten the hexagon nut
(23)
.
If it is excessively tightened, the 5th steam cylinder may deform.
(3) When screwing the 1st steam cylinder
⑭
into the long bolt
(26)
, hold the lower part of the 1st
steam cylinder
⑭
and slightly turn it clockwise.
Also for the same reason above, do not excessively tighten this. If it is excessively tightened,
the 2nd steam cylinder
⑯
may deform.
(4) Tighten the hexagon socket head bolt
⑨
just slightly by hand.
Be sure to wear clean nylon gloves before assembling the nozzles.
