appropriate intervals throughout this manual. Warnings are provided to alert installing contractors
to potential hazards that could result in personal injury or death. Cautions are designed to alert
personnel to hazardous situations that could result in personal injury, while notices indicate a
situation that could result in equipment or property-damage-only accidents.
Your personal safety and the proper operation of this machine depend upon the strict observance
of these precautions.
NOTICE
Check the label on the kit to make sure it corresponds to the unit model number. Never install
this kit on units not listed on the kit label.
NOTICE
Improper installation or miss-applying this kit can result in an ineffective fix and cause early
discharge line failure.
NOTICE
All brackets and weights in this kit must be installed.
ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout
this literature. Read these carefully.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, could
result in minor or moderate injury. It could also be used to alert against unsafe practices.

WARNING
Hazardous Voltage W/ Capacitors!
Disconnect all electric power, including remote disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power can not
be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have
discharged. Failure to disconnect power and discharge capacitors before servicing could result in
death or serious injury.
1. Remove old "handcuff clamps" if installed. (See Figure 1.)
2. Install tube to tube bracket finger tight using the tube clamps provided. The tube to tube bracket
should be as low on the two circuits as possible and before the radius on circuit #1 or circuit
#2 (whichever is closer). See Figure 2.
Note: It may be necessary to gently bring together or spread apart circuit #1 and circuit #2.
3. Tighten all 1/4" flange nuts to 90 in. lbs. to prevent any movement between the discharge lines,
brackets and clamps.
4. Install base bracket by installing the tube clamp on circuit #1 discharge header tube. Align the
base bracket to the tube clamp and install the 1/4” flange nuts finger tight on circuit #1. See
Figure 2.
Note: It’s best to install the tube clamps finger tight until the base bracket is secured using the #10
sheet metal screws and then go back and tighten the 1/4" flange nuts.
Allow the base bracket to align itself with the #1 circuit discharge tube. The base bracket and
circuit #1 discharge header should run parallel to each other once installed. See Figure 2.

5. Drive 2 #10 sheet metal screws to attach the base bracket to the compressor mounting panel.
See Figure 3 for screw locations.
Note: The base bracket must be installed on the compressor mounting base or leaks will occur.
Never penetrate the base pan of the unit or the water tight integrity of the unit will be
compromised.
6. Tighten the two 1/4" flange nuts to fully seat tube clamp to the bracket plus 1/4 turn (90 inch
pounds).
Note: Clamp nuts and base screws must be properly tightened to insure they do not come loose
in running. If a screw strips, add an additional screw.

b. Base bracket parallel to #1 cicuit.
c. Install 1/4" flange nuts finger tight
until base bracket bottom is secured
with #10 sheet metal screws. After
base bracket is installed, fully tighten
the 1/4" flange nuts on clamp (after
clamp is seated against the bracket
continue to tighten ¼ turn).
d. Attach base bracket to compressor
mounting base with 2 #10 sheet
metal screws.
e. Base bracket must be installed on
the compressor mounting base or
leaks will occur.

mounting base.

7. Install two weights on the discharge lines in the locations shown in Figure 5 and Figure 6,
depending on the unit model.
NOTICE
Improper location or attachment of the weights will lead to running vibration failures.
The weights must be at the correct section of the tube. The edge of the weight is placed close
to the bend radius. Use one tube clamp to attach each weight (as shown in Figure 4). Make sure
that the weight is clear of the compressor.
Note: All weights are installed with the edge close to the bend radius (within one inch Figure 4).
Tighten the flange nuts to 90 inch pounds to assure that the clamp and weight will not become
loose.
