• When installing, make sure there is no leakage. When recovering the refrigerant,ground the compressor first before removing the connection pipe.

If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high, It may cause explosion and injur y.

The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor either reduce cooling/heating capacity or lead to a malfuction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the right figure.

1. Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2. Referring to the illustration opposite, tighten the flare nut on section B first manually and then with a torque wrench, applying the following torque.

3. Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port as shown at the figure.

• Make the electrical connection and leave the system into “stand by mode”. Do not turn on the system.

This is necessary to speed up vacuum operation (full OPEN position of

Electronic Expansion Valve - EEV -).

4. Open the valve of the low pressure side of manifold gauge counterclockwise.

5. Purge the air from the system using vacuum pump for about 10 minutes.

 Close the valve of the low pressure side of manifold gauge clockwise.

 Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about 10 minutes. This procedure is very important to avoid a gas leak.

 Turn off the vacuum pump.

 Remove the hose of the low pressure side of manifold gauge.

6. Set valve cork of both liquid side and gas side of packed valve to the open position.

7. Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench.

8. Check for gas leakage.

At this time, especially check for gas leakage from the 3-way valve’s stem nuts(A port), and from the service port cap.

Performing leak tests

LEAK TEST WITH NITROGEN (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R410A, it’s responsable of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar (gauge).

LEAK TEST WITH R410A (after opening valves)

Before opening valves, discharge all the nitrogen into the system and create vacuum.

After opening valves check leaks using a leak detector for refrigerant R410A.

Once you have completed all the connections, check for possible leaks using leak detector specifically designed for HFC refrigerants.
