General Safety Precautions
Product Selection, Installation, and Use
Improper selection, installation, or use can cause personal injury or property damage.
It is solely the responsibility of users, through their own analysis and testing, to select
products suitable for their specic application requirements, ensure they are properly
maintained, and limit their use to their intended purpose.
Follow proper local, state, and federal regulations for proper installation and operational
requirements.
Always use caution and common sense when working with any chemical. Read
the product label and Material Safety Data Sheets (MSDS) carefully and follow the
instructions exactly.
Potential Equipment Hazards
Hot surfaces! This equipment may have very hot surfaces. If an operator contacts a hot
surface, injury may occur. Use protective clothing to prevent injury. If other equipment
comes in contact with a hot surface, damage to the equipment may occur. Ensure the
area around this equipment is kept clear to prevent this damage from occurring.
High pressures! This equipment may contain uids at very high pressures. Prior to
installing, removing, or maintaining this equipment, ensure that the equipment is
isolated from all connecting piping, the equipment is depressurized, the contents have
been drained, and the equipment is cool.

8. Turn the actuator wheel clockwise to raise the rod out of the process stream
and lock the 5/8" collet bolt.
9. Close the process isolation valve.
10. Open the bleeder valve on the holder body to relieve the internal pressure.
11. Remove the Saf-T-Vise STV-HP2 coupon holder from the process isolation
valve; remove the dummy coupon and replace it with new coupon.
12. Follow steps 3-5 to reattach the coupon holder to the process line. Turn the
actuator wheel counter clockwise and lower the rod until the travel check bolt
is level with the mark on the aluminum body.
13. With a rm grip still on the hand crank, tighten the 5/8" locking collet bolt.
14. THIS STEP APPLIES ONLY FOR HOLDERS WITH A GRAFOIL PACKING. ALL
OTHERS PROCEED TO STEP 15: Loosen the ¼" packing gland bolt and turn
the packing gland assembly clockwise until no leak is present. Tighten the ¼"
packing gland bolt.
15. Recheck to ensure 5/8" locking collet bolt is tight against rod/shaft.
16. (OPTIONAL) Remove the actuator wheel to prevent unauthorized use or
tampering.
Retraction Procedure
Tools required
12" adjustable wrench
1. Ensure 5/8" locking collet bolt is tight before proceeding.
2. If necessary, place actuator wheel onto top of Saf-T-Vise STV-HP2 tool and
tighten set screw.
3. With a rm grip on the actuator wheel loosen the 5/8" locking collet bolt and
spin the actuator wheel clockwise to retract the rod/shaft from the line.
4. Once the rod is fully retracted tighten the 5/8" locking collet bolt.
5. Close the process isolation valve.
6. Open the bleeder valve on the holder body to relieve internal pressure.
7. Remove the Saf-T-Vise STV-HP2 Holder from the isolation valve.

Insertion/Retraction Instructions
Tools required
permanent marker
tape measure
12" adjustable wrench
ÂNOTE
35 ft-lb of torque will hold a 3/8" diameter rod in place against up to 5000 psi
of process pressure.
1. Determine the insertion length by measuring from the top of the process
isolation valve to the desired zone within the pipeline and record the length.
(Coupons generally are ¼" from the bottom of the line, atomizers are usually
located in the top 1/3 of the line, and injection quills should be placed in the
middle of the process line with the longer point facing upstream).
2. Loosen the 5/8" locking collet bolt on the holder and extend the rod/shaft by
spinning the actuator wheel counterclockwise.
Failure to loosen the collet bolt may result in damage to the unit.
Stop spinning when the extended rod length is equal to the insertion length.
Make a mark on the aluminum body of the tool with a permanent marker
level with the uid inlet assembly (for atomizers) or the travel check bolt (for
coupon holders).
3. Retract the rod back inside the holder and tighten the 5/8" locking collet bolt
to secure the rod inside the holder.
4. Connect the holder to the CLOSED process isolation valve and securely tighten
the holder to the valve.
ÂNOTE
Use anti-seize on threaded connection points to eliminate any galling or
future seizing.
5. Recheck the locking collet to ensure 5/8" locking collet bolt is tight against
rod/shaft.
6. Slowly open process isolation valve.
ÂNOTE
Some leaks may be present around Grafoil packing (if applicable).
7. With a rm grip on the actuator wheel, loosen the 5/8" locking collet bolt and
turn the hand crank counter clockwise to insert the rod/shaft to the desired
depth. Use the permanent mark made in step 2 to properly achieve the correct
insertion depth.
8. With a rm grip still on the actuator wheel, tighten the 5/8" locking collet bolt.
9. THIS STEP APPLIES ONLY FOR HOLDERS WITH A GRAFOIL PACKING. ALL
OTHERS PROCEED TO STEP 10: Loosen the ¼" packing gland bolt and turn
the packing gland assembly clockwise until no leak is present. Tighten the ¼"
packing gland bolt.
10. Recheck to ensure 5/8" locking collet bolt is tight against rod/shaft.
11. (OPTIONAL) Remove the actuator wheel to prevent unauthorized use or
tampering.
Short Cut Method for Coupon Holders Only
1. Place an old corrosion coupon (dummy coupon) into the coupon chuck at the
bottom of the Saf-T-Vise STV-HP2 coupon holder.
2. Retract the rod back inside the holder and tighten the 5/8" locking collet bolt
to secure the rod inside the holder.
3. Connect the holder to the CLOSED process isolation valve and securely tighten
the holder to the valve.
ÂNOTE
It is advised to use anti-seize on threaded connection points to eliminate any
galling or future seizing.
4. Recheck to ensure 5/8" locking collet bolt is tight against rod/shaft.
5. Slowly open process isolation valve.
ÂNOTE
Some leaks may initially be present around Grafoil packing (if applicable).
6. With a rm grip on the actuator wheel, loosen the 5/8" locking collet bolt and
turn the hand crank counterclockwise to insert the rod until the coupon gently
touches the bottom of the pipe.
7. Turn actuator wheel one turn clockwise to move coupon up ¼", and make a
mark with a permanent marker on the aluminum body at the travel check bolt.
This will give you an accurate insertion depth for all coupons of the same size.
