Prohibited patterns: change to pattern 1 or 2.

To avoid the risk of oil retention to the outmost outdoor unit,always connect the stop valve and the piping betweenoutdoor units as shown in the 4 correct possibilities of thefigure below.

Prohibited patterns: change to pattern 1 or 2.

Change to configuration as in figures below

Correct configuration

If the piping length between the outdoor units exceeds 2 m,create a rise of 200 mm or more in the gas line within alength of 2 m from the kit.

3. LEAK TEST AND VACUUM DRYING

Refer to chapter "7.Leak test and vacuum drying" of the installationmanual.

After connecting the field piping, perform the following inspections.

1 Preparations

Connect a nitrogen tank, a cooling tank, and a vacuum pump tothe outdoor unit and perform the airtightness test and thevacuum drying. The stop valve and valves A and B should beopen and closed as shown in the table below when performingthe airtightness test and vacuum drying.

2 Airtightness test and vacuum drying

4.3. Field line connection: transmission wiring and cool/heat selection

Refer to chapter "8.7.Field line connection: transmission wiring andcool/heat selection" of the installation manual.

In case of RXYCQ24~40

The interconnecting wiring between the outdoor units in thesame piping system must be connected to the Q1/Q2 (Out Multi)terminals. Connecting the wires to the F1/F2 (Out-Out) terminalsresults in system malfunction.

The base unit is the outdoor unit to which the interconnectingwiring for the indoor units is connected.

Fixing transmission wiring

5. ADDITIONAL REFRIGERANT CHARGE

Refer to chapter "11.5.Additional refrigerant charge" of theinstallation manual.

Charging method

As explained during vacuum drying method, once vacuum drying isfinished, additional refrigerant charging can start.

Follow the steps as described below.

1 Calculate the amount of refrigerant to be added using theformula mentioned in "How to calculate the additional refrigerantto be charged".

The first 10 kg of refrigerant can be charged without outdoor unitoperation. If the additional refrigerant amount is smaller than10 kg, perform the precharging procedure as explained in step 2below. If the additional refrigerant charge is larger than 10 kg,perform step 2 and perform step 3 till the end of the procedure.

2 Precharging can be done without compressor running byconnecting the refrigerant bottle only to the liquid stop valve.

Make sure that the stop valves are closed:

3 If the total amount of refrigerant could not be charged byprecharging, then connect the refrigerant bottle to the refrigerantcharging port as described in the figure above.

4 Make sure to open all 3 stop valves of the outdoor unit (see"11.3.Stop valve operation procedure" in the installationmanual).

5 Turn on the power of the indoor units and outdoor unit.

To be able to do this operation, the outdoor unit should be set inmode 2.

6 Push the BS1 MODE button for 5 sec, the H1P LED is on w.

NOTE RXYCQ8 can not install the multi unit transmissionwiring. Run will not be successful if the wiring isconnected to Q1-Q2 (TO MULTI UNIT) terminal.

1 Heating/cooling switching remote control cord (when a heating/cooling switch remote control (optional) is connected) (ABC).

2 Fix to the indicated plastic brackets using field supplied clamping material.

7 Push the BS2 SET button 20 times until following LEDcombination is reached:

8 Push the BS3 RETURN button to confirm setting 2-20 above.

9 Push the BS2 SET button to change the charge mode from OFF(OFF) to ON (ON). LED indication should change as follows

10 Push the BS3 RETURN button and the setting is defined.

11 Push the BS3 RETURN button again, and the refrigerantcharging operation will start.

12 After charging the specified quantity of refrigerant, press theBS3 RETURN button to stop the operation.

Checks after adding refrigerant

Are the stop valves for liquid and gas open?

Is the amount of refrigerant, that has been added, recorded onthe refrigerant charge label?

6. BEFORE OPERATION

Refer to chapter "12.Before operation" of the installation manual.

6.1. Field setting

Refer to chapter "12.3.Field setting" of the installation manual.
