SUCTION AND DISCHARGE TUBE
BRAZING
Compliant Scroll compressors have copper plated steel
suction and discharge tubes. These tubes are far more
rugged and less prone to leaks than copper tubes used on
other compressors. Due to different thermal properties of
steel and copper, brazing procedures may have to be
changed from those commonly used.
•
To disconnect: heat joint Areas 2 and 3 slowly and
uniformly until braze material softens and the tube can
be pulled out of suction fitting. (See Figure 11.)
•
To connect:
–
Recommended brazing materials: silfos with
minimum 5% silver or silver braze material with
flux.
–
Reinsert tube into fitting.
–
Heat tube uniformly in Area 1 moving slowly to
Area 2. When joint reaches brazing temperature,
apply brazing material. (See Figure 11.)
–
Heat joint uniformly around the circumference to
flow braze material completely around the joint.
–
Slowly move torch into Area 3 to draw braze
material into joint. (See Figure 11.)
–
Do not
overheat joint.

1
Motor will deliver consistent CFM through voltage supply range with no deterioration
(197-253V for all 230/208V models).
2
Continuous CFM is the total air being circulated during continuous (manual fan) mode.
3
Will occur automatically with a call for "Y" for cooling mode operation.
4
Will occur automatically with a call for "W1" for heating mode operation.
