Installing DIN Connector Assembly
9. REASSEMBLY OF YOKE CONNECTOR
A. Lay a new disc filter(31) inside the yoke clamp connector(30),
and press it firmly into place with the use of a wooden or plastic
dowel, so that it is seated evenly on all sides.
B. Install the O-ring(29) into the bottom of the yoke connector.
C. Insert the yoke connector through the bottom of the yoke
clamp(24). While holding the yoke clamp and connector together,
mate the connector into the valve body and turn it clockwise by
hand until snug (see Fig. 9).
D. Install a new spare O-ring(26) onto the protective cap(25), and fit
the loop end onto the groove at the top of the yoke clamp. Install
the yoke clamp screw(27) into the yoke clamp, but do not seal the
protective cap at this time.
10. RESASSEMBLY OF DIN CONNECTOR
A. Install both O-rings(37&33) onto the handwheel connector(34).
B. Insert the small end of the conical filter(36) through the small O-
ring and into the threaded end of the handwheel connector, being
careful to avoid pressing the filter too far past the O-ring, which
will cause it to become unseated.
C. Mate the handwheel connector through the threaded end of the
handwheel(35). While holding the handwheel and connector to-
gether, mate the connector into the valve body and turn it clock-
wise by hand until snug (see Fig. 10).
11. Install a vise mounting tool (P/N 1003-95) or a discharged C0
2
car-
tridge (P/N 7039-09) with a HP port adapter (P/N 1020-85) into the
HP port of the valve body(7) which is located near the serial number.
DO NOT use a C0
2
cartridge that has not been discharged. Doing so
may cause the cartridge to rupture, possibly resulting in serious injury.
12. Secure the vise mounting tool inside a bench vise so that the first
stage is positioned standing vertical outside the vice with the dia-
phragm clamp facing up.
13. Mate the pin of the spanner tool into the bore hole of the diaphragm
clamp. While holding the spanner tool securely engaged to prevent it
from slipping, turn the diaphragm clamp clockwise to tighten until it
is flush (metal against metal) with the valve body (see Fig. 11).
Do not install the hydrostatic transmitter, diaphragm, or envi-
ronmental end cap until the final adjustment and testing proce-
dures have been completed.
14. Loosen the vise to turn the first stage over, and re-secure it so that the
flat end (top) faces straight up. Apply a torque wrench with 6mm hex
key socket to tighten the HP balance plug to 12 (±2) foot-lbs.
15. Reposition the first stage inside the vice and secure it with the con-
nector (Yoke or DIN) facing straight up. Apply a torque wrench with
a w" box wrench torque adapter (Yoke) or 6mm hex key socket (DIN).
(See Fig. 12.) Tighten the connector to 12 (±2) foot-lbs.
