A capillary tube ( 023		: Inner diameter 2mm, Length 1000mm) is brazed to a distributor assembly.
Cut and divide the tube to each length as shown below.

	Ref No.	No. of capillary tubes	Cutting

	023	4	200 mm : 2 pcs.
	023	4	400 mm : 2 pcs.
			400 mm : 2 pcs.

[Cutting]

Plane circumference of the capillary tube with triangle file, etc., and then break off it.

NOTE) Break off the capillary tube so that inner diameter is not deformed

2.Attachment of joint pipe

Insert the attached joint pipe into the end of the capillary tube up to 15mm, and braze it.

Form the capillary tube as same as that in the distributor assembly before replacement.

3.Brazing to indoor heat exchanger
