MOUNTING PROCEDURE
(Water-Cooled Casting)
These instructions apply to instruments with water
cooled castings. Instructions for mounting standard
castings are provided in Section 2.11.
The MODLINE 4 is ordinarily mounted by the front
circular flange or base mounting pad to fixed
brackets which have been previously installed to
provide the correct line of sight. Mounting dimen-
sions are given in Fig. 2.14.
The instrument may be mounted in any orientation
that will afford a clear, unobstructed line of sight
and a reliable support, and also allow access to
the water, air and cable fittings.
BASE MOUNTING
If you are mounting the MODLINE 4 with no acces-
sories, attach it to the fixture of your choice using
three 1/4–20 NC bolts. Observe grounding precau-
tions in Section 2.15.
For freedom of final adjustment in sighting, the
Swivel Mounting Base, Model SB-3, is recom-
mended as an optional accessory. See Section 5
for a description of this accessory.
FLANGE MOUNTING
The MODLINE 4 can be flange mounted to mount-
ing supports or accessories by means of three
5/16–18 NC bolts supplied. The flange cutouts and
special bolts provide a "quick disconnect' feature
that makes it easy to remove the MODLINE 4 for
lens cleaning and other service routines. The
mounting procedure is illustrated in Fig. 2.15.
Observe the grounding precautions in Section
2.15.
