For detailed instructions concerning the connection and functioning of the heat pump controller refer to the operating manual supplied with the controller. MOUNTING CAUTION! correct). 7 An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company disable contactor or power contactor) as well as a 3-pole circuit breaker with simultaneous tripping of all external conductors must be provided . The required cross- sectional area of the conductor is to be selected according to the power consumption of the heat pump, the technical connection requirements of the relevant utility company and all applicable regulations. Power consumption data of the heat pump is provided in the product literature and on the nameplate. The terminals are designed for a max. conductor cross-section of 10 mm.. The clockwise phase sequence must be observed when connecting the load line (the heat pump will deliver no output and will be very noisy when the phase sequence is in COMMISSIONING COMMISSIONING 8.1 General Information To ensure proper commissioning it should be carried out by an after-sales service authorized by the manufacturer. Only then can an extended warranty period of 3 years in total be granted (cf. Warranty service). 8.2 Preparation Prior to commissioning, the following items need to be checked: -All connections of the heat pump must have been made as described in Chapter 7. -The heat source system and the heating circuit must have been filled and checked. -The strainer must have been fitted in the sole inlet of the heat pump. -In the brine and heating circuits all valves that could impair the proper heating water flow must be open. -The settings of the heat pump controller must be adapted to the heating installation in accordance with the instructions contained in the controller's operating manual. CAUTION! Commissioning of the heat pump must be performed in accordance with the mounting and operating manual of the heat pump controller. 8.3 Commissioning Procedure The start-up of the heat pump is effected via the heat pump controller. Where an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the requirements of the heating installation. An incorrect setting may result in various error symptoms and an increased electric power consumption. To correctly set the overflow valve, the following procedure is recommended: a) Open all heating circuits and close the overflow valve. Determine the resulting temperature difference between supply and return flow. b) Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump usage) so that the most unfavourable operating state - with respect to the water flow rate - is achieved. c) In this operating state open the overflow valve until approximately the same temperature difference exists that was measured under a) when the overflow valve was closed and the heating circuits open. Any malfunctions occurring during operation are displayed on the heat pump controller and can be corrected as described in the operating manual of the heat pump controller. 8 CARE/CLEANING CARE/CLEANING 9.1 Care The heat pump is maintenance-free. To prevent malfunctions due to sediments in the heat exchangers, care must be taken that no impurities can enter the heat source system and heating installation. In the event that operating malfunctions due to contamination occur nevertheless, the system should be cleaned as described below. 9.2 Cleaning of Heating Side The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust). It is therefore important - in particular with respect to the piping of underfloor heating systems - that the installation is executed in a diffusion-proof manner. Also residues of lubricating and sealing agents may contaminate the heating water. In the case of severe contaminations leading to a reduction of the performance of the condenser in the heat pump, the system must be cleaned by a heating technician. According to current knowledge, we recommend cleaning with a 5% phosphoric acid solution or, in the case that cleaning needs to be performed more frequently, with a 5% formic acid solution. In either case, the cleaning fluid should be at room temperature. It is recommended that the heat exchanger be cleaned in the direction opposite to the normal flow direction. To prevent acidic cleaning agents from entering the circuit of the heating installation we recommend that the flushing device be fitted directly to the supply and return lines of the condenser. To prevent any damage caused by cleaning agent residues that may be present in the system it is important that the system be thoroughly flushed using appropriate neutralising agents. The acids must be used with great care, all relevant regulations of the employers' liability insurance associations must be adhered to. If in doubt, contact the manufactu...
