10.3.3. Storing and managing Piping Materials1. Types of piping and their storage

The following is a general classification of the refrigerant pipe materials used for ACs.

Because the gas pressure of R410A is approximately 1.6 times as high as that of R22, copper pipes with the thickness shownin Table 10, and with minimal impurities must be used. Care must also be taken during storage to ensure that pipes are notcrushed, deformed, or scratched, and that no dust, moisture or other substance enters the pipe interior. When storing sheathedcopper pipes or plain copper pipes, seal the openings by pinching or taping them securely.

2. Makings and managementa. Sheathed copper pipes and copper-element pipes

When using these pipes, check to make sure that they are the stipulated thickness. For flare nuts, be sure to used the samenut that is used on the AC unit.

PrecautionsBe sure to read the instructions for the vacuum pump,vacuum pump adaptor and manifold gauge prior to use,and follow the instructions carefully.Make sure that the vacuum pump is filled with oil up tothe designated line on the oil gauge.The gas pressure back flow prevention valve on thecharging hose is generally open during use. When youare removing the charging hose from the service port, itwill come off more easily if you close this valve.

Fig. 12 Vacuum pump air purging configuration

b. Copper pipesUse only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe isexposed, you should take special care, and also take measures such as marking the pipes to make sure they are easilydistinguished from other piping materials, to prevent mistaken use.

3. Precautions during refrigerant piping workTake the following precautions on-site when connecting pipes. (Keep in mind that the need to control the entry of moisture anddust is even more important that in conventional piping).

a. Keep the open ends of all pipes sealed until connection with AC equipment is complete.b. Take special care when doing piping work on rainy days. The entering of moisture will degrade the refrigerating machine oil,

and lead to malfunctions in the equipment.c. Complete all pipe connections in as short a time as possible. If the pipe must be left standing for a long time after removing

the seal, it must be thoroughly purged with nitrogen, or dried with a vacuum pump.

10.4. INSTALLATION, TRANSFERRING, SERVICING10.4.1. Inspecting Gas Leaks with a Vacuum Pump for New Installations (Using New

Refrigerant Piping)1. From the viewpoint of protecting the global environment, please do not release refrigerant into the atmosphere.

a. Connect the projecting side (pin-pushing side) of the charging hose for the manifold gauge to the service port of the 3-wayvalve. (1)

b. Fully open the handle Lo of the manifold gauge and run the vacuum pump. (2) (If the needle of the low-pressure gaugeinstantly reaches vacuum, re-check step a).)

c. Continue the vacuum process for at least 15 minutes, then check to make sure the low-pressure gauge has reached -0.1MPa (-76 cmHg). Once the vacuum process has finished, fully close the handle Lo of the manifold gauge and stop thevacuum pump operation, then remove the charging hose that is connected to the vacuum pump adaptor. (Leave the unit inthat condition for 1-2 minutes, and make sure that the needle of the manifold gauge does not return.) (2) and (3)

d. Turn the valve stem of the 2-way valve 90 counter-clockwise to open it, then, after 10 seconds, close it and inspect for a gasleak (4)

e. Remove the charging hose from the 3-way valve service port, then open both the 2-way valve and 3-way valve. (1) (4) (Turnthe valve stem in the counter-clockwise direction until it gently makes contact. Do not turn it forcefully).

f. Tighten the service port cap with a torque wrench (18 N.m (1.8 kgf.m)). (5) Then tighten the 2-way valve and 3-way valvecaps with a torque wrench (42 N.m (4.2 kgf.m)) or (55 N.m (5.5 kgf.m)).

g. After attaching each of the caps, inspect for a gas leak around the cap area. (5) (6)

10.4.2. Transferring (Using New Refrigerant Piping)1. Removing the unit

a. Collecting the refrigerant into the outdoor unit by pumping downThe refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when thetemperature of the room is low.

Check to make sure that the valve stems of the 2-way valve and 3-way valve have been opened by turning them counter-clockwise. (Remove the valve stem caps and check to see that the valve stems are fully opened position. Always usea hex wrench (with 4-mm opposing sides) to operate the valve stems.)Press the TEST RUN button on the indoor unit, and allow preliminary for 5-6 minutes. (TEST RUN mode)After stopping the operation, let the unit sit for about 3 minutes, then close the 2-way valve by turning the valve stem inthe clockwise direction.Press the TEST RUN button on the indoor unit again, and after 2-3 minutes of operation, turn the valve stem of the 3-way valve quickly in the clockwise direction to close it, then stop the operation.Tighten the caps of the 2-way valve and 3-way valve to the stipulated torque.Remove the connection pipes (liquid side and gas side).

2. Installing the unitInstall the unit using new refrigerant piping. Follow the instructions in section 4.1 to evacuate the pipes connecting the indoorand outdoor units, and the pipes of the indoor unit, and check for gas leaks.

10.4.3. AC Units Replacement (Using Existing Refrigerant Piping)When replacing and R410A AC unit with another R410A AC unit, you should re-flare the refrigerant piping. Even though thereplacement AC unit uses the R410A, problems occur when, for example, either the AC unit maker or the refrigerating machine oilis different.When replacing an R22 AC unit with an R410A AC unit, the following checks and cleaning procedures are necessary but aredifficult to do because of the chemical characteristics of the refrigerating machine oil (as described in items c) and d) of section10.1.1.(2)). In this case, you should use new refrigerant piping rather than the existing piping.

1. Piping checkBecause of the different pressure characteristics of R22 and R410A, the design pressure for the equipment is 1.6 timesdifferent. the wall thickness of the piping must comply with that shown in Table 10, but this is not easy to check. Also, even ifthe thickness is correct, there may be flattened or bent portions midway through the piping due to sharp curves. Buried sectionsof the piping also cannot be checked.

2. Pipe cleaningA large quantity of refrigerating machine oil (mineral oil) adheres to existing pipes due to the refrigeration cycle circulation. If thepipes are used just as they are for the R410A cycle, the capacity will be lowered due to the incompatibility of this oil with theR410A, or irregularities may occur in the refrigeration cycle. For this reason, the piping must be thoroughly cleaned, but this isdifficult with the present technology.

10.4.4. Refrigerant Compatibility (Using R410A Refrigerant in R22 ACs and Vice Versa)Do not operate an existing R22 AC with the new R410A refrigerant. Doing so would result in improper functioning of the equipmentor malfunction, and might lead to a major accident such as an explosion in the refrigeration cycle. Similarly, do not operate anR410A AC with R22 refrigerant. The chemical reaction between the refrigerating machine oil used in R410A ACs and the chlorinethat is contained in R22 would cause the refrigerating machine oil to degrade and lead to malfunction.

10.4.5. Recharging Refrigerant During ServicingWhen recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure.

1. Connect the charging hose to the service port of the outdoor unit.2. Connect the charging hose to the vacuum pump adaptor. At this time, fully open the 2-way valve and 3-way valve.3. Fully open the handle Lo of the manifold gauge, turn on the power of the vacuum pump and continue the vacuum process for

at least one hour.4. Confirm that the low pressure gauge shows a reading of -0.1 Mpa (-76 cmHg), then fully close the handle Lo, and turn off the

vacuum pump. Wait for 1-2 minutes, then check to make sure that the needle of the Low pressure gauge has not returned. SeeFig. 13 for the remaining steps of this procedure.

5. Set the refrigerant cylinder onto the electronic scale, then correct the hose the cylinder and to the connection port for theelectronic scale. (1)(2)Precaution:

Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquidwithout having to turn the cylinder around

6. Remove the charging hose of the manifold gauge from the vacuum pump adaptor, and connect it to the connection port of theelectronic scale. (2)(3)

7. Open the valve of the refrigerant cylinder, then open the charging valve slightly and close it. Next, press the check valve of themanifold gauge and purge the air. (2)(4) (Watch the liquid refrigerant closely at this point.)

8. After adjusting the electronic scale to zero, open the charging valve, then open the valve Lo of the manifold gauge and chargewith the liquid refrigerant. (2)(5) (Be sure to read the operating instructions for the electronic scale.)

9. If you cannot charge the stipulated amount, operate the unit in the cooling mode while charging a little of the liquid at a time(about 150 g/time as a guideline). If the charging amount is insufficient from one operation, wait about one minute, then use thesame procedure to do the liquid charging again.Precaution:

Never use the gas side to allow a larger amount of liquid refrigerant to be charged while operating the unit.10. Close the charging valve, and after charging the liquid refrigerant inside the charging hose, fully close the valve Lo of the

manifold gauge, and stop the operation of the unit. (2)(5)11. Quickly remove the charging hose from the service port. (6) If you stop midway through, the refrigerant that is in the cycle will

be discharged.12. After putting on the caps for the service port and operating valve, inspect around the caps for a gas leak. (6)(7)

10.4.6. BrazingAs brazing requires sophisticated techniques and experiences, it must be performed by a qualified person.In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while lettingdry nitrogen gas (N2) flow.

- 48 -

U U U U

<Brazi ng Method for Preven ting Oxidat ion>1. Attach a reducing valve to the nitrogen gas cylinder.2. Attach a reducing valve to the nitrogen gas cylinder.3. Apply a seal onto the clearance between the piping and inserted pipe for the nitrogen gas in order to prevent the nitrogen gas

from flowing backward.4. When the nitrogen gas is flowing, be sure to keep the piping end open.5. Adjust the flow rate of nitrogen gas so that it is lower than 0.05 m3/h, or 0.02 MPa (0.2 kgf/cm2) by means of the reducing valve.6. After taking the steps above, keep the nitrogen gas flowing until the piping cools down to a certain extent (i.e. temperature at

which pipes are touchable with finger).7. Completely remove the flux after brazing.

Cautions during brazing1. General Cautions

a. The brazing strength should be high as required.b. After operation, airtightness should be kept under pressurized condition.c. During brazing do not allow component materials to become damaged due to overheating.d. The refrigerant pipe work should not become blocked with scale or flux.e. The brazed part should not restrict the flow in the refrigerant circuit.f. No corrosion should occur from the brazed part.

2. Preventing of OverheatingDue to heating, the interior and exterior surfaces of treated metal may oxidize. Especially, when the interior of the refrigerantcircuit oxidizes due to overheating, scale occurs and stays in the circuit as dust, thus exerting a fatally adverse effect. So,make brazing at adequate brazing temperature and with minimum of heating area.

3. Overheating ProtectionIn order to prevent components near the brazed part from overheating damaged or quality deterioration due to flame or heat,take adequate steps for protection such as (1) by shielding with a metal plate, (2) by using a wet cloth, and (3) by meansof heat absorbent.

4. Movement during BrazingEliminate all vibration during brazing to protect brazed joints from cracking and breakage.

5. Oxidation PreventativeIn order to improve the brazing efficiency, various types of antioxidant are available on the market. However, theconstituents of these are widely varied, and some are anticipated to corrode the piping materials, or adversely affect HFCrefrigerant, lubricating oil, etc. Exercise care when using an oxidation preventive.

10.4.7. Servicing TipsThe drier must also be replaced whenever replacing the refrigerant cycle parts. Replacing the refrigerant cycle parts firstbefore replacing the drier. The drier is supplied in a vacuum pack. Perform brazing immediately after opening the vacuumpack, and then start the vacuum within two hours. In addition, the drier also needs to be replaced when the refrigerant hasleaked completely.
