209 Detailed technical drawings RZASG-MV1/MY1 To determine if adding additional refrigerant is necessary If Then (L1+L2+L3+L4+L5+L6+L7)≤ 30 m (chargeless length) You do not have to add additional refrigerant. (L1+L2+L3+L4+L5+L6+L7)> 30 m (chargeless length) You must add additional refrigerant. For future servicing, encircle the selected amount in the tables below. INFORMATION Piping length is the largest one way length of liquid piping. To determine the additional refrigerant amount (R in kg) (in case of pair) L1 (m) L1: 30~40 m 40~50 m R: 0.35 kg 0.7 kg To determine the additional refrigerant amount (R in kg) (in case of twin, triple and double twin) 1. Determine R1 and R2. If Then G1>30 m Use the table below to determine R1 G1≤30 m (and G1+G2>30 m) R1=0.0 kg. Use the table below to determine R2. Length (total length of liquid piping−30 m) 0~10 m 10~20 m 20~30 m 30~40 m 40~45 m R1: 0.35 kg 0.7 kg 1.05 kg(a) 1.4 kg(a) R2: 0.2 kg 0.4 kg 0.6 kg 0.8 kg(a) 1 kg(b) a) Only for RZASG100~140. b) Only for RZASG100+125. 2. Determine the additional refrigerant amount: R=R1+R2. Examples Layout Additional refrigerant amount (R) L2=7 m (Ø6.4 mm) L3=5 m (Ø6.4 mm) L1=35 m (Ø9.5 mm) RZASG100 Case: Twin, standard liquid pipe size 1. G1 Total Ø9.5 => G1=35 m G2 Total Ø6.4 => G2=7+5=12 m 2. Case: G1>30 m R1 Length=G1−30 m=5 m => R1=0.35 kg R2 Length=G2=12 m => R2=0.4 kg 3. R R=R1+R2=0.35+0.4=0.75 kg L2=15 m (Ø6.4 mm) L3=12 m (Ø6.4 mm) L4=17 m (Ø6.4 mm) L1=5 m (Ø9.5 mm) RZASG125 Case: Triple, standard liquid pipe size 1. G1 Total Ø9.5 => G1=5 m G2 Total Ø6.4 => G2=15+12+17=44 m 2. Case: G1≤30 m (and G1+G2>30 m) R1 R1=0.0 kg R2 Length=G1+G2−30 m = 5+44−30=19 m => R2=0.4 kg 3. R R=R1+R2=0.0+0.4=0.4 kg 4PEN485928-1D_2019_04 Click here to view all RZASG-MV1 technical drawings on my.daikin.eu Click here to view all RZASG-MY1 technical drawings on my.daikin.eu
