Tubing Connections For Flowrator Model; Tubing Connections For Txv Models; Condensate Drain Lines - Goodman RS6200006 Installation And Operationg Instructions

NOTE: The use of a heat shield is strongly recom-
mended when brazing to avoid burning the serial plate
or the finish of the unit. Heat trap or wet rags must be
used to protect heat sensitive components such as ser-
vice valves and TXV valves sensing bulb.

7.4 Tubing Connections for Flowrator Model

1. Loosen the 13/16 nut 1 TURN ONLY to allow high pres-
sure tracer gas to escape. No gas indicates a possible
leak.
2. After the gas has been expelled, remove the nut and
discard the black or brass cap plastic seal.
3. Remove the flowrator piston to verify it is the correct
size for the outdoor unit being installed and then replace
the piston (changing size, if needed). See piston kit chart
in the literature kit for appropriate piston size.
4. Remove the spin closure on the suction line using a
tube cutter and deburr the tube.
5. Insert the suction line into the connection, slide the in-
sulation and the rubber grommet at least 18" away from
the braze joint.

6. Remove the tailpiece clamped to the exterior of the cabi-
net or in the literature kit packet and slide the 13/16 nut
into place.

7. Braze tailpiece to the line set liquid tube and braze suc-
tion line connection. Quench all brazed joints with a
damp rag upon completion of brazing. Do not allow water
to enter the inside of the tubing.
8. AFTER THE TAILPIECE HAS COOLED, confirm posi-
tion of the white Teflon
nut.
9. Torque the 13/16 nut to 7-25 ft-lbs. or tighten 1/6 turn.
Excessive torque can cause orifices to stick. Use the
proper torque settings when tightening orifices.

7.5 Tubing Connections for TXV Models

TXV models come with factory installed TXV with the
bulb pre-installed on the vapor tube.
1. Remove refrigerant tubing panel or coil (lower) access
panel.
2. Remove access valve fitting cap and depress the valve
stem in access fitting to release pressure. No pressure
indicates possible leak.
3. Replace the refrigerant tubing panel.
4. Remove the spin closure on both the liquid and suction
tubes using a tubing cutter.
5. Insert liquid line set into liquid tube expansion and slide
grommet about 18" away from braze joint.
6. Insert suction line set into suction tube expansion and
slide insulation and grommet about 18" away from braze
joint.
7. Braze joints. Quench all brazed joints with water or a
wet rag upon completion of brazing.

8 Condensate Drain Lines

The coil drain pan has a primary and a secondary drain with
3/4" NPT female connections. The connectors required are
3/4" NPT male, either PVC or metal pipe, and should be hand
tightened to a torque of no more than 37 in-lbs. to prevent
damage to the drain pan connection. An insertion depth of
approximately 3/8" to 1/2" (3-5 turns) should be expected at
this torque.
1. Ensure drain pan hole is not obstructed.
2. To prevent potential sweating and dripping on to finished
space, it may be necessary to insulate the condensate
drain line located inside the building. Use Armaflex
similar material.
