How to Install Sanitary Water Tank Kit

Follow below procedures Step 1 ~ Step 5.

To establish sanitary water circuit, 3way valve and sanitary water tank kit is required.

Step 1. Uncover the water tank kit and locate it on the wall.

Step 2. Connect the water tank kit to the main power like the below figure 2.

Step 3. Connect the water tank kit to the Main PCB Assembly1 like the below figure 2.

Step 4.

Connect power cord of sanitary tank heater. It is located inside of the tank. Refer to the next

page for more information.

Step 5.

Find sanitary water tank sensor

Step 6.

Connect the Main PCB to terminal block with wire(Part 4) like figure 3.

※ This wire is only for AHBWXXXA0 model.

. Plug it to 'CN_TH4' (Red Connector) of the main PCB

assembly 1.

Like below figure. 1

The sensor should be mounted correctly to the sensor hole of sanitary water tank.

Installing recirculation pump

When is used with sanitary water tank, it is STRONGLY recommended to install recirculation

pump to prevent flooding out cold water at the end of hot water supply and to stabilize the water temperature

inside the sanitary water tank.

- The recirculation pump should be operated when sanitary water demand is not required. Therefore, external

time scheduler to determine when the recirculation pump should turn on and turn off is required.

- The operating duration time of the recirculation pump is calculated as follow :

Duration time [minute] = (k*V)/R

k : 1.2 ~ 1.5 is recommended. (If distance between pump and tank is far, then choose high number.)

V : Volume of sanitary water tank [liter]

R : Water flow rate of pump [liter per minute], which is determined by pump performance curve.

- The pump operating start time should be prior to the sanitary water demand.

Wire specification

• Cross-sectional area of the wire should be over 5mm2.

• You should use the shield wire for the signal wire in terminal block 5,6 not

to make the electric noise.

Adjusting thermostat temperature

• To guarantee proper operation, it is recommended to set temperature of

thermostat to maximum temperature (symbol

at the figure 3).
