Additional charging of refrigerant

Over 30 m please, add refrigerant quantity according to following
tables. 

For future servicing, mark with a circle the selected amount on the
tables below

For pair system

Additional charging amount <unit: kg>

For twin/triple system

Please charge additionaly according to the following calculation.

1

Calculate the total length (L) of all liquid piping in the system.

Twin 

(See figure 3)

L=L1+L2+L3

Triple 

(See figure 4)

: L=L1+L2+L3+L4

In case L<30 meter: no additional charging is required

In case L>30 meter calculate:

1. Calculate G1:

Calculate total length of Ø9.5 

mm liquid piping (main

branch piping)

2. Calculate G2:

Calculate total length of Ø6.4 mm liquid piping (branch piping)

3. In case G1>30 meter, proceed to step 2

In case G1<30 meter, proceed to step 3

2

Calculate length G1 over 30 meter (G1–30 m)

Based on this length, decide R1 from the table below
Based on G2, decide R2 from the table below.
Proceed to step 4

3

Calculate total length over 30 meter (G1+G2–30 m)

Based on this length, decide R2 from the table below
R1=0 meter

Length <unit: m>, additional charge amount <unit: kg>

4

The total additional charge amount R=R1+R2 (kg)

Refrigerant charge amount=R=R1+R2=1.00+0.30=1.30 kg

Example 2

G1=L1=5 m

G2=L2+L3+L4=17+17+20=54

Refrigerant charge amount=R=R1+R2=0.0+0.9=0.9 kg

Total charging weight of the refrigerant (after a leak, 
etc.)

When the entire refrigerant pipe length is within 30 meters, charge
the refrigerant in accordance with the amount mentioned in the
nameplate, and when the pipe length exceeds 30 meters, the
charging amount mentioned in the nameplate and that required for
additional charging are to be totalled as the net charging amount.

NOTE

In case of complete recharge of the refrigerant, please first
execute vacuuming. Execute this vacuuming from the
service port. Do not use the port of the stop valve for
vacuuming. Vacuuming can not be executed completely
using such port.

Position of service port:

Heat pump: Heat pump units have 2 ports on the
piping. One between the liquid receiver and the
electronic expansion valve and another one between
the heat exchanger and the 4-way valve.
Cooling only: On the discharge pipe
