Installation for the first time 4. Installation for the first time Air and moisture in the refrigerant system have undesirable effects as below: ● Pressure in the system rises. ● Operating current rises. ● Cooling or heating efficiency drops. ● Moisture in the refrigerant circuit may freeze and block capillary tubing. ● Water may lead to corrosion of parts in the refrigerant system.
Installation for the first time 7) Turn the flare nut of the 3-way valves about 45°counterclockwise for 6 or 7seconds after the gas coming out, then tighten the flare nut again. Make sure the pressure display in the pressure indicator is a little higher than the atmosphere pressure. Then remove the charge hose from the 3 way valve. 8) Fully open the 2 way valve and 3 way valve and securely tighten the cap of the 3 way valve. 4.2. Air purging by refrigerant Procedure: 1).
Installation for the first time 7). Mount the valve stems nuts and the service port cap. Be sure to use a torque wrench to tighten the service port cap to a torque 18N·m. Be sure to check the gas leakage. 4.3. Adding the refrigerant if the pipe length >5m Electronic scale Procedure: 1). Connect the charge hose to the charging cylinder, open the 2-way valve and the 3-way valve. Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder.
Adding the refrigerant after running the system for many years 5. Adding the refrigerant after running the system for many years Electronic scale Procedure: 1). Connect the charge hose to the 3-way service port, open the 2-way valve and the 3-way valve. Connect the charge hose to the valve at the bottom of the cylinder. If the refrigerant is R410A, make the cylinder bottom up to ensure liquid charge. 2). Purge the air from the charge hose.
Re-installation while the indoor unit need to be repaired 6. Re-installation while the indoor unit need to be repaired 6.1. Collecting the refrigerant into the outdoor unit Procedure 1). Confirm that both the 2-way and 3-way valves are set to the opened position Remove the valve stem caps and confirm that the valve stems are in the opened position. Be sure to use a hexagonal wrench to operate the valve stems. 2). Connect the charge hose with the push pin of handle lo to the 3-way valves gas service port.
Re-installation while the indoor unit need to be repaired 6.2. Air purging by the refrigerant Procedure: 1). Confirm that both the 2-way and 3-way valves are set to the closed position. 2). Connect the charge set and a charging cylinder to the service port of the 3-way valve Leave the valve on the charging cylinder closed. 3). Air purging. Open the valves on the charging cylinder and the charge set.
Re-installation while the outdoor unit need to be repaired Be sure to check the gas leakage. 7. Re-installation while the outdoor unit need to be repaired 7.1. Evacuation for the whole system Procedure: 1). Confirm that both the 2-way and 3-way valves are set to the opened position. 2). Connect the vacuum pump to 3-way valve’s service port. 3). Evacuation for approximately one hour. Confirm that the compound meter indicates -0.1Mpa. 4).
Re-installation while the outdoor unit need to be repaired 7.2. Refrigerant charging Procedure: 1). Connect the charge hose to the charging cylinder, open the 2-way valve and the 3-way valve Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder. If the refrigerant is R410A, make the cylinder bottom up to ensure liquid charge. 2).
