2. INSTALLATION

To establish sanitary water circuit, 3way control valve and sanitary water tank kit is required. If solar thermal system is pre-installed at theinstallation field, solar thermal kit is required to interface solar thermal system – to – sanitary water tank – to –

General Informationsupports following 3way valve.

(1) : SPDT = Single Pole Double Throw. Three wires consist of Live1 (for selecting Flow A), Live 2 (for selecting Flow B), and Neutral (for common).

(2) : “Flow A” means ‘water flow from the indoor unit to under floor water circuit.’

(3) : “Flow B” means ‘water flow from the indoor unit to sanitary water tank.’

Specific conditions are required for installation place such as service space, water pipe length and height, total volume of water and waterquality.

General Considerations• The installation location is frost-free.

• Make sure to make the piping in size 1" or more (and reduce to 3/4" at the inlet of the tank) as to have sufficient water volume in the pipingbetween indoor unit and sanitary water tank.

• Locate the sanitary water tank in a suitable position to facilitate ease of maintenance, remember access is required to the electrical box.

• Provide a connection for the relief valve blow-off and drain.

• To avoid back siphonage it is advised to install a non-return valve on the water inlet of the sanitary water tank in accordance with local andnational regulations.

• Take care that in the event of a leak, water can not cause any damage to the installation space and surroundings.

Installing Sanitary Water Tank1. Check if all sanitary water tank accessories are enclosed.

2. When floor mounting, place the sanitary water tank on a level surface.And make sure the sanitary water tank is mounted level.

3. Apply thermal paste to the thermistor and insert the thermistor as deep as possible in the thermistor socket. Fix using the nut provided.

How to Install Sanitary Water Tank KitFollow below procedures Step 1a ~ Step 6.

Step 1. Find a relay contactor and ELB in the kit. Bolt them into control box.(symbol at picture)

Step 2. Connect ‘CN_B/HEAT(A)’ (White Connector) of the indoor unit PCBwith relay contact using included cable (symbol at the picture).Connect relay contactor port no. 0 and 1.

Step 3. Connect relay contactor port no. 2 and 4 with ELB port no. 2 and 4.(symbol at the picture).

Check Polarity• Connect relay contact port no. 2 to ELB port no. 2• Connect relay contact port no. 4 to ELB port no. 4

Step 4. Connect relay contactor port no. 3 and 5 with terminal block 1 port 6and 7. (symbol at the picture).

Check Polarity• Connect relay contact port no. 3 to terminal block 1 port 6• Connect relay contact port no. 5 to terminal block 1 port 7

Step 5. Connect ELB port no. 1 and 3 with terminal block 3 port 3 and 4.(symbol at the picture).

Check Polarity• Connect ELB port no. 1 to terminal block 3 port 3• Connect ELB port no. 3 to terminal block 3 port 4


Step 6. Find sanitary water tank sensor. Connect it to ‘CN_TH4’ (Red Connector) of the indoor unit PCB (symbol at the picture). Thesensor wire should be passed through holes for sensor (symbol and at the picture). The sensor should be mounted correctlyto the sensor hole of sanitary water tank.

Sensor mountingInsert sensor into sensor socket and bolt it tightly.

How to Wire Sanitary Water Tank HeaterStep 1. Uncover heater cover of the sanitary water tank. It is located side of the tank.

Step 2. Find terminal block and connect wires as below. Wires are field-supplied item.

(L) : Live signal from PCB to Heater

(N) : Neutral signal from PCB to Heater

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

IMPORTANT: Make sure that the element enters the thread ring freely and tighten.

CAUTION: After adjustments are completed, ensure the lid to the electrical box is replaced correctly and the retaining screw isfitted.

CAUTION: If electric element (5) or thermostat (4) is defective, contact authorized electrician.

3.Replacement

WARNINGIncorrect handling of safety valves, thermostat and other valves may lead to tank rupture. Follow instructions carefully:

Replacement of the heating element

CAUTION: Remember before resetting the safety cut-off or altering the thermostat setting, isolate electrical supply to the unitprior to removal of the electrical box lid.

1. Always turn off main power (8) when water supply is shut off.2. Test free operation of safety valves regularly by opening valves and ensuring that water runs out.3. Electrical connection and repair operations should only be carried out by an authorized electrician.4. Fitting and repair of plumbing fixtures should only be carried out by an authorized plumber.5. When replacing thermostats, safety valves and other valves supplied with this unit, use only approved parts of same specification.

1. Disconnect the power cable (8).2. Remove the electric lid (3) in front of the electric box.3. Shut valve (1) fully towards – clockwise until the valve is completely closed.4. Open safety relief valve (10) . (Close the valve by turning counter clockwise until it clicks.)5. Loosen screw X and disable the wires.6. Remove the heating element (5) with the element socket tool Y. A certain amount of water will now come out of the element hole.7. Quickly rinse the O-ring slot and get ready to install the new heating element (5).8. Enter the new heating element with a new O-ring seal.

9. Open valve (1) and check that the heating element is not leaking.10. Mount the wires X and Y and tighten properly.11. Reconnect the power cable (8). Adjust the mixing valve (see "Installation and directions for use").



Replacement of the thermostat

1. Remove the electric lid (3) in front of the electric box.2. Loosen the 4 screws X and Y and disable the wires X and Y.3. Remove the thermostat (4) and replace this with a new one.4. Mount the wires X and Y properly.
