9. Clockwise phase sequence in the case of multiphase units must be observed Damage to the compressor may be incurred if it is operated in the wrong sense of rotation Do not use any cleaning agents containing sand soda acid or chloride as these may damage the surface To prevent consequential damage it is imperative that the water circuits be neutralized after cleaning using appropriate agents The unit is not suitable for operation with a frequency converter Work on the refrigeration circuit may be performed by qualified persons only 1 2 Legal Provisions and Guidelines This heat pump was designed and built in compliance with all relevant EU directives DIN and VDE regulations see CE Declaration of Conformity The electrical connection of the heat pump must be performed according to and conforming with all re levant VDE EN and IEC standards Beyond that all technical connection requirements of the local electrical utility company have to be adhered to On connecting the heating system all relevant regulations have to be heeded 1 3 Energy Efficient Use of the Heat Pump By purchasing this heat pump you contribute to the protection of the environment A prerequisite for energy efficient operation is the proper design of the heat source system and the heat utilization system One of the most important factors of heat pump efficiency is keeping the temperature difference between the heating water and the heat sou
10. The heating water minimum flow rate through the heat pump must be assured in all operating states of the heating system This can be accomplished for example by installing a differential pressure free manifold or an overflow valve The procedure for setting an overflow valve is described in the Chapter Commissioning Frost Protection On heat pumps installed in a location prone to frost a manual drain valve see Hydraulic Block Diagrams in the Appendix should be provided Properly installed appliances feature an internal frost protection feature If the heat pump is taken out of service or in the event of a power failure the system must be drained In heat pump installations where a power failure cannot be readily detected e g holiday houses the heating circuit must contain a suitable antifreeze product 6 3 Electrical Connection The power connection of the heat pump is effected via a standard 3 core for 1 phase units or a 5 core for 3 phase units cable In the case of the 1 phase units an additional 3 core cable must be installed for the electric back up heater The cable s has have to be supplied by the client the cross sectional area is to be selected in accordance with the power consumption of the heat pump see Equipment Data in the appendix as well as all relevant VDE EN and VNB regulations The power supply of the heat pump must be equipped with an all pole disconnecting device with a contact gap of at l
11. When using 3 4 carrying pipes be sure to secure them against shifting so as to avoid injuries to your hands during transport When slipping the carrying pipes through the frame care must be taken that no components in particular the plastic condensate pan or the drain pipe socket are damaged 5 1 General The unit should always be installed on a permanently level smooth and horizontal floor The base frame with its contact surfaces should make close contact with the floor in order to prevent any structure borne noise from being transmitted If this is not possible additional sound absorbing measures might become necessary It must be possible to carry out servicing activities without any problems This is assured if a clearance of 1 2m is maintained all around the unit 1 2m 12m The air intake and discharge openings must not be restricted nor obstructed 5 2 Condensate Line The condensation water that may collect during operation must be drained in a place protected from frost The heat pump must be positioned horizontally so that proper discharge can be ensured The condensation water pipe must have a minimum diameter of 50 mm and should be discharged to the sewer drain in a frost proof location The condensate pipe has to be placed centered unterneath the drain pipe fitting of the condensate pan see also dimensioned drawing in the Appendix Al ternative condensate discharge options have t
