to scratch either part. Carefully remove the restrictor
orifi ce from the distributor body. See Figure 3.
3. Check the actual size of the new orifi ce. The size is
stamped on its side. Do not use pin gauges to measure
the orifi ce diameter.
4. Insert the new orifi ce into the distributor body, rounded
end down. See Figure 4.
CAUTION:
To prevent damage to the unit or internal
components, it is recommended that two
wrenches be used when loosening or tightening
nuts. Do not over tighten!
5. Realign the assembly nut on the distributor body and
hand tighten both components. Mark a line on both
bodies and then tighten an additional 1/4 turn using two
wrenches. The movement of the two lines will show how
much the nut is tightened. If a torque wrench is used,
tighten to 10-12 ft. lbs. or 14-16 Nm.
6. Proceed to the appropriate lineset connection section.
See pages 4 - 5.

Installing a TXV Kit
A separate TXV kit and C5 replacement tube kit are
required. See Tables 5 - 7 (pages 6 - 8).
CAUTION:
To prevent damage to the unit or internal
components, it is recommended that two
wrenches be used when loosening or tightening
nuts. Do not over tighten!
1. Using two wrenches, loosen the distributor and liquid line
body halves. Turn the assembly nut counter-clockwise.
2. Discard the removed liquid line.
3. Insert a light-gauge wire hook between the distributor
body and the restrictor orifi ce while being careful not
to scratch either part. Carefully remove the restrictor
orifi ce from the distributor body. See Figure 3.
4. Connect the distributor to the outlet side of the valve.
5. Braze the new liquid line from the C5 replacement
tube kit and liquid line stub & screen (included
in TXV kit) with dry nitrogen fl owing through the
joints. IMPORTANT: Brazing operation should be
performed before connecting assembly to the TXV.
This protects the TXV from heat. Liquid nitrogen
prevents internal oxidation and scaling from occurring.
NOTE: The liquid line is sold separately, see Table 5
(page 6) for appropriate part number.
6. Connect the liquid line to the inlet side of the valve.
7. Realign the assembly nut on the distributor body and
hand tighten both components. Mark a line on both
bodies and then tighten an additional 1/4 turn using two
wrenches. The movement of the two lines will show how
much the nut is tightened. If a torque wrench is used,
tighten to 10-12 ft. lbs. or 14-16 Nm.
8. Using two wrenches, tighten both ends of the valve.
9. Secure the sensing bulb to the suction line using the
clamp supplied with the kit.
