- Page 5 „I“ - the water tank of the indoor unit is made of chromium-nickel alloy steel. “S” – the water heater has a heat exchanger The maximum allowable refrigerant system pressure in the heat pump water heaters is 2.7 MPa. They are tested and designed to operate at pressures lower than 2.7 MPa. For this purpose, a valve is installed in their construction to prevent pressure exceeding the maximum permissible Heat pump water heaters are designed to heat water, except through a heat pump system, also with a 2000 W electric heater.

- Page 8 Description Outer diameter [mm] Thickness [mm] 1/4“ 6,35 3/8“ 9,52 b) Remove the protection nuts of the refrigerant nipples on the indoor unit (make sure there are no dirt and moisture); c) Cut the pipes longitudinally with a suitable tool, avoiding the formation of a seam and damages. The cut must be perpendicular to the axis of the pipe (Fig.
- Page 9 h) Connect the pipes to the refrigerant nipples on the indoor unit by screwing the nuts with appropriate torque. When installing, make sure that the pipes are properly leveled to avoid damage. If the torque is insufficient, there will be a refrigerant leak. It is advisable to use a torque wrench, in this case, use the data in the table: 6,35 mm (1/4") Approximately 150-200 kgcm (15-20 Nm)
- Page 10 a) Remove the plugs of the two-way, three-way valve on the outdoor unit and the service valve. Check that both of the outdoor unit valves are closed; b) Connect a vacuum pump to the service valve. c) After opening the pump valve, turn it on and let it run. Create a vacuum for about 40-45 minutes. d) Check that the arrow on the pressure gauge shows pressure equal to 1 bar (or -76 cm Hg);...
- Page 11 than 0.5 MPa, the installation of a pressure reducing valve (reducing valve) is mandatory. In case local regulations require the use of additional devices that are not included in the kit and are not included in the package, they must be purchased and installed as prescribed. The indoor unit is complete with a combined non-return safety valve.
- Page 12 The safety valve, if necessary, also serves to drain water from the water tank. This is done as follows: The indoor unit is switched off from the electric grid by means of the auxiliary device and, for safety reasons, the electric fuse in the phase circuit to the water heater is switched off. Cold water supply to the appliance is stopped - close the crane (4 of Figure 12).
- Page 13 WARNING! It is obligatory to install such device in the power supply circuit of the appliance which, in the conditions of category III overvoltage, ensures complete disconnection of all poles. The conductors of the circuit between the device and the input electrical terminals of the appliance must not be interrupted by another breaker or fuse.

Even when the water heater is in the "Off" mode when there is heat in the solar collector, the circulation pump will be switched on to discharge the heat! To support the solar installation when there is insufficient heat, the water heater can use the heat pump and electric heater.
- Page 27 When selecting the item Turned off, the heat pump and the electric heater will not be switched on. The solar system continues to operate normally to prevent overheating of the solar collector. The normal functioning of the protection modes also continues: protection against freezing of the water tank and solar collector and overheating protection of the solar collector by automatic activation of the mode Vacation for discharge of accumulated energy.
- Page 28 When using the heat from the solar installation, the temperature threshold up to which the water heater will be heated is 85 ° C measured by sensor t2. After this threshold the circulation pump will be switched off in order not to transfer more heat to the water heater. When selecting the mode Vacation, only the solar installation and the protection modes will remain activated.
