4.4.1 To check for leaks

NOTICE

Do NOT exceed the unit's maximum working pressure (see "PS High" on the unit name plate).

NOTICE

Make sure to use a recommended bubble test solution from your wholesaler. Do not use soap water, which may cause cracking of flare nuts (soap water may contain salt, which absorbs moisture that will freeze when the piping gets cold), and/or lead to corrosion of flared joints (soap water may contain ammonia which causes a corrosive effect between the brass flare nut and the copper flare).

1 Charge the system with nitrogen gas up to a gauge pressure of at least 200 kPa (2 bar). It is recommended to pressurize to 3000 kPa (30 bar) in order to detect small leaks.
2 Check for leaks by applying the bubble test solution to all connections.
3 Discharge all nitrogen gas.

4.4.2 To perform vacuum drying

1 Vacuum the system until the pressure on the manifold indicates -0.1 MPa (-1 bar).
2 Leave as is for 4-5 minutes and check the pressure:

If the pressure... Then..
Does not change There is no mo	moisture in the system. This procedure is finished.
Increases There is moisture in the system. Go to the next step.

3 Vacuum the system for at least 2 hours to a manifold pressure of -0.1 MPa (-1 bar).
4 After turning the pump OFF, check the pressure for at least 1 hour.
5 If you do NOT reach the target vacuum or CANNOT maintain the vacuum for 1 hour, do the following:

• Check for leaks again.
• Perform vacuum drying again.

NOTICE

Make sure to open the stop valves after installing the refrigerant piping and performing vacuum drying. Running the system with the stop valves closed may break the compressor.

1 In cooling mode, select the lowest programmable temperature. In heating mode, select the highest programmable temperature. Test run can be disabled if necessary.

2 When the test run is finished, set the temperature to a normal level. In cooling mode: 26\~28°C, in heating mode: 20\~24°C.

3 The system stops operating 3 minutes after the unit is turned OFF.

INFORMATION

- Even if the unit is turned OFF, it consumes electricity.

- When the power turns back on after a power break, the previously selected mode will be resumed.

5.4 Starting up the outdoor unit

See the indoor unit installation manual for configuration and commissioning of the system.

6 Disposal

NOTICE

Do NOT try to dismantle the system yourself: dismantling of the system, treatment of the refrigerant, oil and other parts MUST comply with applicable legislation. Units MUST be treated at a specialised treatment facility for reuse, recycling and recovery.

6.1 Overview: Disposal

Typical workflow

Disposing of the system typically consists of the following stages:

1 Pumping down the system.

2 Bringing the system to a specialized treatment facility.

INFORMATION

For more details, see the service manual.

6.2 To pump down

DANGER: RISK OF EXPLOSION

Pump down – Refrigerant leakage. If you want to pump down the system, and there is a leak in the refrigerant circuit:

- Do NOT use the unit's automatic pump down function, with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the operating compressor.

- Use a separate recovery system so that the unit's compressor does NOT have to operate.

NOTICE

During pump down operation, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump down, air will be sucked into the system. Compressor breakdown or damage to the system can result due to abnormal pressure in the refrigerant cycle.

Pump down operation will extract all refrigerant from the system into the outdoor unit.

1 Remove the valve cap from the liquid stop valve and the gas stop valve.
2 Carry out forced cooling. See "6.3 To start and stop forced cooling" on page 11.
3 After 5 to 10 minutes (after only 1 or 2 minutes in case of very low ambient temperatures ( <-10^ )), close the liquid stop valve with a hexagonal wrench.
4 Check on the manifold if the vacuum is reached.
5 After 2-3 minutes, close the gas stop valve and stop forced cooling.

6.3 To start and stop forced cooling

There are 2 methods to perform forced cooling.

• Method 1. Using the indoor unit ON/OFF switch (if present on the indoor unit).
• Method 2. Using the indoor unit user interface.

6.3.1 To start/stop forced cooling using the indoor unit ON/OFF switch

1 Press the ON/OFF switch for at least 5 seconds.

Result: Operation will start.

INFORMATION

Forced cooling stops automatically after 15 minutes.

2 To stop operation sooner, press the ON/OFF switch.

6.3.2 To start/stop forced cooling using the indoor unit user interface

1 Set the operation mode to cooling.

For the procedure, refer to "To perform a test run" in the installation manual of the indoor unit.
