Procedure and Tools for Refrigerant Piping Work
Piping work for R-407C model partially differs from R-22 model in items and procedures of piping work and refrigerant charging due to
different component and higher pressure for R-407C. The below chart shows general work procedure for R-407C model.
Procedure
Prior to work
Work
Determination of work item
Check the refrigerant to be used
Preparing of working drawing
Mounting sleeves and inserts
Installing indoor unit
Refrigerant piping work
Drain piping work
Duct work
Insulation work
Electric work (Connection wiring / Power supply)
Setting various items
Foundation work for outdoor unit
Installation of outdoor unit
Air tight test
Vacuum drying
Refrigerant additional charging
Test run / Adjustment
Preparing documents required before delivery
Delivery / Operation instruction
Confirm the refrigerant is R-407C or R-22
(1) Check wall thickness of copper tube (Refer to the table "Wall
thickness of refrigerant pipe")
(2) Maintain cleanliness inside of pipe.
(3) Make sure to conduct N
2
blowing when brazing is required.
(4) Pay attention on pipe flaring and oil to be coated on flared section.
(5) Be sure to use torque wrench.
(1) Make sure to conduct air tight test.
(2) Confirm the pressure of 3.2 MPa does not decrease for 24 hours.
(In case the design pressure of 3.2 MPa)
(1) Vacuum grade is -755 mmHg or lower
(2) Use dedicated vacuum pump
Preparation of documents and drawings in accordance with local
codes and standard.
(1) Confirm the correct amount of refrigerant.
(2) Be sure to charge refrigerant in liquid phase.
(3) Use the dedicated gauge manifold and charging hose.
(4) The refrigerant amount to be charged is shown in the installation manual.
(5) Record the added refrigerant amount to the record sheet.
