* Direction of the drained water

Mechanical diagram showing a gear and linkage mechanism (no text or labels)

- Make sure the indoor unit is in upright position when you pour water to check for leakage. Make sure that the water does not overflow onto the electrical part.

Purging the connected pipes

The outdoor unit is loaded with sufficient R22 refrigerant. Do not vent R22 into atmosphere: it is a fluorinated greenhouse gas. You should purge the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as seen in the picture.

- 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 injury.

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

2. Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque:

• Excessive torque can be cause of gas leakage.

- Make the electrical connection and leave the system into "stand by mode". Do not turn on the system!

2. Open the valve of the low pressure side of manifold gauge counterclockwise.
3. Purge the air in the connected pipes using the vacuum pump for about 15 minutes.

▶ Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about 10 minutes.

This procedure is very important to avoid a gas leak.

▶ Close the valve of the low pressure side of manifold gauge clockwise.
▶ Turn off the vacuum pump.
▶ Check for 2 minutes if there is any pressure change.
▶ Remove the hose of the low pressure side of manifold gauge.

1. Set a valve cork of liquid and gas service port to the open position.
2. 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.
3. Check for a gas leak paying particular attention to the 3-way valve's stem nuts and to the service port cap.

Technical diagram of two mechanical fasteners labeled C and D, showing bolted joint configurations (no text or symbols beyond labels)

Leak test with nitrogen (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R22, it's responsible of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar (gauge).

Leak test (after opening valves)

Before opening valves, discharge all the nitrogen from the system and create vacuum according to page 39.

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

Pump down (before disconnecting the refrigerant connections for unit repair, removal or disposal)

Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit.

This operation must be carried out before disconnecting the refrigerant tubing in order to avoid refrigerant loss to the atmosphere.

▶ Shut off the liquid valve with the Allen wrench.
▶ Turn the system on in cooling with fan operating at high velocity.
(Compressor will immediately start, provided 3 minutes have elapsed since the last stop).
▶ After 2 minutes of operation, shut the suction valve with the same wrench.
▶ Turn the system off and switch mains supply off.
▶ Disconnect tubing. After disconnection, protect valves and tubing ends from dust.
▶ Compressor damage may occur if run at a negative suction pressure.
