obtain information from loeal Carrier distributor.
If 1-1/8in. tubing is used (38QB042,048,060),
braze it to the accessory 1-1/8 x 3/4-in. suction
connection adapter (Carrier Part No. 28AU900061)
or to a correctly sized field-supplied adapter, then
make Compatible Fitting connections. Isolate inter­
connecting tubing from framing and ductwork or
where tubing runs thru stud spaces, enelosed ceilings
or pipe chases. Use isolation type hangers. Fig. 3,
since rigid fastening transmits pulsations to struc­
ture creating objectionable sound.
