| Appliance details System theory The refrigerant circuit is a closed system in which the refrigerant R134a circulates as a heat transfer medium. The evaporator transfers the heat from the air to the refrigerant circuit, and the refrigerant evaporates into a gas. The compressor compresses the refrigerant R134a, thus increasing its temperature. Then the heat is transferred via a heat exchanger, also referred to as a condenser, to the storage water tank. The refrigerant R134a condenses in the process.

Failing to do so will result in a dangerous situation (section 4.4.4).
Installation instructions | 15 energy-saving devices may shorten the life of the water heater and may endanger life and cause property damage. WARNING: This water heater SHOULD NOT be installed in an area with a corrosive atmosphere where chemicals or flammable liquids are stored or where aerosol propellants are released. When using outdoors, because of natural air movement in a room or other enclosed space, these corrosive/flammable vapours can be carried from where they are being used or stored.
| Installation instructions In New Zealand, the installation must comply with Clause G12 of the New Zealand Building Code. 4.4 Water piping WARNING: All plumbing work must be carried out by a qualified professional and in accordance with the Plumbing Standard AS/NZS 3500.4 and local authority requirements. All packaging materials must be removed from the water heater prior to its installation.
Installation instructions | 17 4.4.2 Dielectric joint (not supplied with the appliance) Different metals between plumbing and tank materials and additionally the effect of hot water can cause the corrosion of one of the metals (generally the one in the tank is the metal attacked). The Dielectric Joint will basically avoid any physical contact between the two metals, acting as an effective insulator and prevent this attack.
| Installation instructions WARNING: Never block or seal the outlet of the PTR valve or it's drain for any reason. The warranty will be void if the relief valve or other safety devices are tampered with or if the installation is not in accordance with this manual. Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact any electrical parts, persons or animals and to eliminate any other possible risks.
Installation instructions | 19 This water heater must be directly connected to a 230V-240V AC, 50Hz mains power supply. When connected off grid, please make sure a 230V-240V AC 50Hz true sine wave power supply is available. WARNING: Proper ground connection is essential. The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Non metallic piping, dielectric unions, flexible connectors, etc., can cause the water heater to be electrically isolated.
| Installation instructions ▶ Rotate circulation pump speed selector to position „III“. CAUTION: ▶ Choose the right path to move the unit. ▶ Only move the unit in its original packaging. ▶ If the unit is installed in a metal building, proper insulation and compliance with the relevant technical standards of electrical equipment is to be provided. 4.
Installation instructions | 21 ▶ Open the purge screw of the circulation pump and leave it opened until the water leaks uniformly without visible air bubbles. 6720801244-19.1V Fig. 14 Circulation pump purge screw ▶ Close the circulation pump purge screw. ▶ Wait for about 5 minutes until „Purg“ mode goes off. During the 5min the Purg function lasts, open the purge valve for a few seconds several times. This will release some air excess from the water loop.
| Installation instructions 3. Condensate lines are in place • Condensate drain pipe connected to drain connection, and directed into a floor drain or a condensate pump 4. Temperature and pressure-relief valve is working and drain line completed per local code. 5. Electrical connections • Electrical connections are properly isolated 6.

Installation instructions | 23 4.10 What to expect for “normal startup” After the unit has been installed, with all electrical and water connections secure and checked, the unit should be filled with water (vent tank by opening a hot water faucet somewhere in home to allow tank to fully fill with water). Once tank is full and power is energized, the user must press the POWER button on the user interface. Elapsed time HPWH actions Comments 0 to 5 minutes Unit is silent.
| Operation Instructions 5 5.1 Operation Instructions WARNING: If the hot water system is not used for two weeks or more, flammable hydrogen gas may accumulate in the water heater. To dissipate this gas safely, it is recommended that a non-electrically operated hot tap be fully opened for 2 minutes. During this procedure, smoking, open flames or operating electric appliances should be avoided. 1 2 menu - + ok 6720800765-03.1V Fig.
