Reply to:Mark Lenckowski
General drawing notes:* Red tubing – discharge* Purple tube – suction and/or evaporator* Yellow tube – oil line to compressor* Orange tube – discharge (separator to heat exchanger)
* Hi temp stage – R134A (approx 10oz)* Low temp stage – R508 (approx 100-120PSIG)
* All access ports will have caps (not drawn)

Heat exchanger
Cold stagerefrigeration
Approx 32”
Warm stagerefrigeration
Warm stage circuit (front)
DISCHARGE: (red) ¼” tube X 52” long
Q3: is two loops sufficient for vibration control?
SUCTION: (purple) 3/8” tube X 92” long
Q1: is two loops OK for vibration control?Q2: is 5/16” tube an option?
Warm stage circuit (left)
Schrader access valveSAE ¼” flare (discharge side)
Q4: Is this style of valve OK on the discharge circuit?
Shut-off/access valve (packed) withSAE 3/8” flare port. Henry 7763-B valve or equivalent.
Q7: Is this an acceptable style of valve?Q8: Is this location acceptable?
.042” capillary tube90” long
This feature is copied from picturesof Scientemp equipment.
Q5: Is it an expansion chamber orFilter dryer?Q6: If a filter dryer, is 100 mesh sizeto be used?
Filter dryer to keep capillary tube clear (drawn as 1” X 6” size)
Q9: Is 100 mesh size good to use?Q10: Is the size (volume) acceptableQ11: does filter dryer need to be verticalor is about 30deg OK?
