6.7.4 To charge refrigerant: Flow chart

For more information, see "6.7.5To charge refrigerant"on page27.

Pre-charging refrigerant

Step 1

Calculate additional refrigerant charge amount: R (kg)

Refrigerant overcharge happened, recover

refrigerant to reach R=Q

Step 2

• Open valves C and B to the liquid line

• Execute pre-charging amount: Q (kg)

Step 3a

• Close valves C and B

• Charging is finished

• Fill in the amount on the additional

refrigerant charge label

• Go to test run

Step 3b

Close valves C and B

R=Q R>QR<Q

About the electrical wiring 30
After knocking out the holes we recommend removing any burrs 30
And paint the edges and areas around the holes using repair paint to prevent rusting 30
Apart from each other transmission wiring and power supply wiring may cross but may not run parallel 30
As to prevent the lid or other parts from coming loose 30
B g g h h 30
Be sure to follow the limits below if the unit to unit cables are 30
Be sure to keep the power line and transmission line 30
Beyond these limits it may result in malfunction of transmission 30
Branching is allowed after branching see figure below 30
F f f h 30
Field piping can be routed from front or bottom of the unit going left or right refer to 6 to route the refrigerant piping on page 19 30
Firmly close the lid and arrange the electrical wires so 30
For the above wiring always use vinyl cords with 0 5 to 1 5 m 30
Guidelines when knocking out knockout holes 30
Hp 10 16 hp 30
Installation 30
It is important to keep the power supply and the transmission wiring separated from each other in order to avoid any electrical interference the distance between both wiring should always be at least 25 mm 30
Maximum inter unit wiring length between outdoor units 30 m 30
Maximum number of branches 16 30
Maximum number of independent interconnectable systems 10 30
Maximum wiring length 1000 m 30
Notice 30
Prevent damage to the wires by wrapping the wiring with protective tape putting the wires through field supplied protective wire conduits at that location or install suitable field supplied wire nipples or rubber bushings into the knockout holes 30
Sheath or cables 2 core wires 3 core wire cables are allowable for the cooler heater changeover user interface only 30
The transmission wiring outside the unit should be wrapped and routed together with the field piping 30
To punch a knockout hole hit on it with a hammer 30
To route and fix the transmission wiring 30
Total wiring length 2000 m 30
Touch internal piping except the inverter pcb cooling pipe in order to avoid wire damage due to high temperature piping 30
Transmission wiring and power supply wiring may not 30
Transmission wiring can be routed through the front side only fix it to the upper mounting hole 30
Transmission wiring to cool heat selector 500 m 30
Up to 16 branches are possible for unit to unit cabling no 30
