4.0 INSTALLATION
1. Thoroughly clean the mounting area and
ensure that all connection pipes and hoses
are free of contaminants. Do not remove
coupler port covers until connections will
be made.
NOTE: Do not rotate the coupler quickly
when oil is not in the system. Oil film
bearings are necessary to ensure smooth
rotation. Couplers may be rotated slowly by
hand before connection.
CAUTION: Never rotate coupler
while dry when it is connected to the
rotary table.
2. Align the coupler in the centre of rotation of
the table and connect one end, using the
tapped female mounting screw holes.
Depending on the application, the coupler
can be mounted so that it is driven by either
the outer or the inner ring.
3. To connect the other side, pin the mounting
holes.
NOTE: The drive plate should have
clearance holes to allow a tolerance for
slight misalignment,
alignment is difficult to achieve.
CAUTION: The drive screw must
drive the coupler, not the connection
pipes or hoses, or damage to the
coupler and connections will occur.

5.0 ADAPTOR MANIFOLD PLATES
The adaptor manifold plates are used to
convert the CRV series 2 and 4 passage rotary
unions to allow for o-ring manifold mounting to
a fixture plate. The plates (AMP-2 and AMP-4)
bolt to the top of the rotary union using the
supplied bolts. The o-ring seals on the plates
match up to seal around the standard ports on
the rotary union. The bolts connecting this
plate to the rotary union should be tightened to
a torque of 150 in-lbs (16.96 Nm).
Once the plate is bolted to the rotary union, it
now must be bolted to the fixture surface. Use
bolts of quality Grade 8 (Din 12.9) thread size
/
5
- 18 (M8) and length a minimum of
16
1 /
1 in (38.1 mm). These bolts are not supplied
2
by Enerpac. The bolts should pass through the
bolt holes on the outside of the mounting
adaptor, and thread into the fixture plate. The
fixture plate surface should be smooth to a
surface finish of R a 63µ in (1.60µ m). Tighten
these bolts to a minimum torque of 150 in-lbs
(16.96 Nm).
