Fitting the Gateway™ ATR Flow Through Top Plate
The Gateway™ ATR Flow Through Top Plate fits onto the top of the
Gateway optical unit via alignment of the round hole (
1
) and slot hole
(
2
) on the underside of the Top Plate over the two fixing location pins
(
3
) on the optical unit. (See
Fig 2
and
Fig 3
.)
Fig 2. Round and Slot Location Holes on Underside of
Gateway™ ATR Flow Through Top Plate
The Gateway™ ATR Flow Through Top Plate is fitted and positioned
the correct way around on the optical unit when the round hole (
1
) is
placed over the
right side
location pin (
3R
) and the slot hole (
2
) is
placed over the
left side
location pin (
3L
) as viewed from the front of
the optical unit. The main body plate (
4
) of the Top Plate should be
sitting flush and even all the way around its edge onto the top surface
of the optical unit when properly located.
Note:
To maintain a correct optical alignment for consistency of optical
throughput energy of the Gateway™ ATR Flow Through Top
Plate, it should always be placed onto the optical unit the same
way around after removal for cleaning or crystal replacement
etc, with the round (1) and slot (2) holes fitting over their correct
and respective fixing location pins (3R) and (3L).
