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.

Installation

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.

Installation

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.

Figure 2. Base bracket installation

a. Bottom of tube to tube clamp close

to highest tube radius.

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.

Figure 3. Screw locations

a. Vertical plate must be flat against and parallel to header

tube.

b. Horizontal plate must be flat against the compressor

mounting base.

c. Two #10 sheet metal screws must be screwed into

compressor mounting or leaks will occur.

Installation

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.

a. Position weights just before the

fourth bend after the

compressor, within one inch of

the bend radius, and clear of

compressor.
