Thepre-pressure shoulddecrease by 0.1 bar foreach metre below 7 m.▪ Check if the watervolume does NOTexceed the maximumallowed water volume.>7 m Do the following:▪ Increase the pre-pressure according tothe requiredinstallation heightdifference. The pre-pressure shouldincrease by 0.1 bar foreach metre above 7 m.▪ Check if the watervolume does NOTexceed the maximumallowed water volume.The expansion vessel ofthe outdoor unit is toosmall for the installation.In this case, it isrecommended to installan extra vessel outsidethe unit.(a) This is the height difference (m) between the highest pointof the water circuit and the outdoor unit. If the outdoor unitis at the highest point of the installation, the installationheight is 0 m.(b) The maximum water volume is 185 l in case the circuit isonly filled with water, and 105 l in case the circuit is filledwith water and glycol.Minimum flow rateCheck that the minimum flow rate (required during defrost/backupheater operation) in the installation is guaranteed in all conditions.NOTICEIf glycol was added to the water circuit, and thetemperature of the water circuit is low, the flow rate willNOT be displayed on the user interface. In this case, theminimum flow rate can be checked by way of the pumptest (check that the user interface does NOT display error7H).NOTICEWhen circulation in each or certain space heating loops iscontrolled by remotely controlled valves, it is important thatthe minimum flow rate is guaranteed, even if all valves areclosed. In case the minimum flow rate cannot be reached,a flow error 7H will be generated (no heating or operation).See the installer reference guide for more information.Minimum required flow rateThe system contains a backup heater / DHW tankwith recirculation pump / glycol15 l/minThe system does NOT contain a backup heater /DHW tank with recirculation pump(a) / glycol20 l/min(a) If an EKHWP tank is installed, no recirculation pump isrequired.See the recommended procedure as described in "6.2 Checklistduring commissioning" on page 21.3.3 Preparing electrical wiring3.3.1 Overview of electrical connections forexternal and internal actuatorsItem Description Wires MaximumrunningcurrentOutdoor unit power supply1 Power supply foroutdoor unit2+GND (a)2 Normal kWh rate powersupply2 6.3 AUser interface3 User interface 2 (b)Optional equipment4 Remote outdoor sensor 2 (c)Field-supplied components5 Domestic hot waterpump2 (c)6 Space heating/coolingoperation control (orshut‑off valve)2 (e)Interconnection cable7 Interconnection cablebetween outdoor unitand control box2 (d)(a) Refer to name plate on outdoor unit.(b) Cable section 0.75 mm² till 1.25 mm²; maximum length:500 m.
