Detail of work
“IN” and “OUT” are marked on the
inside of the flare insulation. Mount the
portion marked “IN” near the unit body
and the portion marked “OUT” on the
field piping side.
• Fasten the insulated pipe with the
insulation tape.
• Firmly secure the insulation with the
provided tie band (4) at the position
indicated on the drawing.
• Fasten the flare insulation with the
provided tape (3).
• Fasten with the provided tie band (4)
at the position indicated on the
drawing.
Item to be observed
• Using the flare insulation of a different type
may result in condensation forming. Check
the type name on the insulation and be sure
to use the correct one.
• To prevent a gap from forming near the
unit’s side plate, be sure that the flare
insulation firmly contacts the unit’s side
plate before mounting.
• Incorrectly mounting the “INNER” and
“OUTER” sides of the insulation may result
in condensation forming.
Seal the slit securely so that there are no
openings. Be sure to mount the insulation so
that the slit is on the top.
Seal the slit securely so that there are no
openings. Be sure to mount the insulation so
that the slit is on the top.
Notes:
*1
Insert the flare nut into the field refrigerant piping. Pull the insulation material back at the area where it will be flared, then return
it to its original position after performing the flare work.
Exposing copper piping may result in condensation forming. Be extremely careful when performing this operation.
*2
There must be no gap.
*3, *4 There must be no gap. Slit should be on the top.
Work procedures
