INSTALLATION Installation Installing the groundwater station 3.2 Installing the brine circuit Note Read and observe chapter “Installing the heat source system” in the installation instructions for the brine/ water heat pump. f Install a safety assembly in the brine circuit. Note Some brine/water heat pumps are supplied with a safety assembly.
INSTALLATION Installation 3.2.2 Heat pump manager settings Appliance damage f First set parameter “SOURCE” to ETHYLENE GLY- COL and then set parameter “SOURCE MIN” to 2 °C on heat pump manager WPM II. If the heat pump has an integral heat pump manager, observe the following information.
INSTALLATION Commissioning Required water quality Common problems when using groundwater as a heat source include: - Erosion of heat exchanger and water supply lines. - Heat exchanger corrosion. - Sludge contamination or blockages in heat exchanger and supply lines. - Sedimentation (blocking) of the return well. To prevent such problems, the quality of the groundwater used as heat source must meet the following standards: - The water must not contain any matter which might...
INSTALLATION Appliance handover Examples: To open the heat exchanger, proceed as follows: 7 °C 4 °C Δϕ1 Δϕ2 2 °C 4 °C 10 °C 7 °C Δϕ1 Δϕ2 5 °C 7 °C Note The groundwater station should only be commis- sioned if there is a sufficient flow rate on the heat source side.
