2. INSTALLATION Conditions where Sanitary Water Tank is Installed Specific conditions are required for installation place such as service space, water pipe length and height, total volume of water and water quality. 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 piping between 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 and national 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 Tank 1. 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. Sanitary Water Tank and Sanitary Water Tank Kit/Solar Thermal Kit To establish sanitary water circuit, 3way control valve and sanitary water tank kit is required. If solar thermal system is pre-installed at the installation field, solar thermal kit is required to interface solar thermal system to sanitary water tank to General Information supports following 3way valve. Type Power Operating Mode Supported SPDT 3-wire (1) 230V AC Selecting Flow A between Flow A and Flow B (2) Selecting Flow B between Flow A and Flow B (3) Yes Yes (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. - 13 -

3.Replacement WARNING Incorrect handling of safety valves, thermostat and other valves may lead to tank rupture. Follow instructions carefully: 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. CAUTION: Remember before resetting the safety cut-off or altering the thermostat setting, isolate electrical supply to the unit prior to removal of the electrical box lid. CAUTION: If electric element (5) or thermostat (4) is defective, contact authorized electrician. CAUTION: After adjustments are completed, ensure the lid to the electrical box is replaced correctly and the retaining screw is fitted. Replacement of the heating element 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. IMPORTANT: Make sure that the element enters the thread ring freely and tighten. 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"). - 18 -
