Only operate the heat pump when allpoints have been satisfied in essence.Heating circuit checklistDuring planning, was consideration given to parts of the buildingthat are to be heated at a later time?Was the power for the domestic hot water supply considered?Were the heating circuits in the system hydraulically balanced?Were leakage pressures determined by pipe network calculations?If planning calculations showed that pressure losses were to be ex-pected: Was a second pump incorporated to overcome the pres-sure losses?Was the minimum mass flow of the heat pump considered?Was a dirt filter incorporated in the return?Was the system provided with all the safety devices described inthis manual?Were an overflow funnel and blow-out line incorporated?Have the pipes and flexible connecting hoses been insulated withthermal insulation?Was the heating circuit flushed, filled and bled?Was the heating circuit checked for leaks?Were the pipes thermally insulated against vapour diffusion?Brine circuit checklist (VWS only)Was the brine circuit pressure tested with water and checked forleaks?Were the water/antifreeze mixing proportions(e.g. 2:1) observed?Was the frost protection (-15 °C) tested with a frost protectiontester?Was a pressure switch incorporated in the brine circuit?Was the pressure switch connected to the heat pump?Was a dirt filter fitted at the brine side input to the heat pump?Were stop valves incorporated into the brine circuit?Were pressure regulating valves incorporated into the brine cir-cuit?Were the brine circuits hydraulically balanced?Was the brine expansion tank fitted?Was the brine source circuit filled to a pressure of 1.5 bar?Was the brine expansion tank filled to 2/3 full?Were isolating devices fitted ahead of the heat pump?Have the pipes and flexible connecting hoses been made diffusion-tight using thermal insulation?Table 14.1 Start-up checklistStart-up checklist 14
