They include a description of the start-up procedure that should be carried out by a competent expert authorised by the manufacturer. Use the following Contents to find the relevant Chapters for the correct mounting and installation of the pump.
Page 4: Safety Warnings
In order to prevent oxidation in the central heating system and heat pump condenser, add an anti-corrosive agent to the water. Any repairs and adjustments to the pump must be made by a Gorenje authorised servicing technician only. Before any repair, disconnect the pump from the power supply source.
Page 5: Statutory Requirements
Water-to-water Heat Pump Statutory Requirements This heat pump was made in compliance with the applicable standards and complies with the related requirements. The heat pump may be connected to a heat source, heating system or electric power supply, in compliance with applicable regulations. Electric connection must be fixed, via a circuit breaker switch that cuts off supply to all conductors.
Page 6: Purpose Of Use
Water-to-water Heat Pump 3. Use Purpose of Use The water-to-water heat pump is designed for installation in residential buildings (e.g., when renovating the boiler room or as a heating source in newly constructed buildings). Underground water of adequate quality and temperature is used as a heat source. Operating Principles Underground water of adequate quality and temperature (17 to 13°C) is claimed by means of immersion pump from a well, at adequate depth.
Page 7 Water-to-water Heat Pump 4. Tehnical caracteristic The construction of the heat pump unit allows installation indoors; the unit housing is made of sheet metal, incorporating an operating panel used for adjustment of the required parameters by the user. The control unit, located under the upper part of the unit, is used for connection to the electricity supply and for connection of the circulating pump, temperature probes and mixing valves.

The increased volume will be absorbed by the expansion vessel, whose dimensions must correlate with the capacity of the heating system (not all heating circuits have a related expansion vessel). The safety valve should be triggered when the pressure reaches 3 bar.
Page 17 Water-to-water Heat Pump Borehole fo Pumping the Water (Well) Water from the underground that is needed for the operation of the water-to-water heat pump is pumped from the well (borehole) The quantity of the groundwater must correspond to the heat pump flow rate.
Page 18 Water-to-water Heat Pump Borehole for Returning the Water (secondary borehole) Water that is sligthly cooled (2 to 3 C) is dishcarged from the water pump and returned to the underground water source. The borehole shall be made on a distance 10 – 15 m along the water flow direction in order to avoid mixing the warm source (inlet water) and the cold source (outlet water).
