How to Install Sanitary Water Tank Kit or DHW Tank Kit

Fellow bellow procedures Spet 1 ~ Step 6 Step 1. Find magnetic switch and ELB(MCCB) in the kit. Fit them into the indoor unit control box with

enclosed a braket and screws.(symbol

Step 2. Contact ‘CN_B/HEAT(A)’(white connector)of the indoor unit PCB with magnetic switch

contact using encolsed cable(symbol port no. A1 and A2.

Step 3. Connect magnetic switch contactor port no.L1 and L3 with ELB(MCCB) port no. 2 and

Check Poarity

• Connect magnetic switch contact port no. L1 to ELB(MCCB) port no.2

• Connect magnetic switch contact port no. L3 to ELB(MCCB) port no.4

Step 4. Connect magnetic switch contactor port no. T1 and T3 with terminal block 1 port 6 and

Check Polarity

• Connect magnetic switch contact port no. T1 to terminal block 1 port 6

• Connect magnetic switch contact port no. T3 to terminal block 1 port 7

Step 5. Connect ELB(MCCB) to Terminal Block.
