Cleaning and user maintenance shall not be made by children without supervision. Children should be supervised to ensure that they do not play with the appliance.
1.3 Electrical connection ⚠⚠ The electrical installation must only be carried out by an authorized electrician (and must follow applicable local and national regulations). The electrical installation must be carried out using permanently routed cables. It must be possible to isolate the power supply using an all-pole circuit breaker for the intended current. For information regarding maximum load for externally connected devices, see electrical installation instructions.

See the figure below for an example on how the pipes can be routed.
3 Drilling holes for brine pipes 4 • Make holes in the walls for the entry pipes (1) for the coolant pipes. Follow the dimensions and connection diagrams on pages 7-8. • The output and input coolant pipes must have wall lead-ins. • If there is a risk of infiltration by ground water, special lead-ins must be used. • Install the entry pipes (1) so that they incline slightly downwards. The incline should be at least 1 cm per 30 cm.
5 Piping installation 5.2 ⚠⚠ To prevent leaks ensure that there are no stresses in the connecting pipes! • Ensure that the pipe installation is carried out in accordance with the dimensions and connection diagrams. • Pipe installation must be carried out by an authorized installer. ⚠⚠ NOTE! It is extremely important that the heating system is completely bled. ⚠⚠ NOTE! Bleed valves must be installed where necessary. 5.1 Heating system supply pipe and return pipe • Install a filter (max mesh size 0.
6 Electrical Installation 6.1 Electrical connection ⚠⚠ The electrical installation must only be carried out by an authorized electrician (and must follow applicable local and national regulations). The electrical installation must be carried out using permanently routed cables. It must be possible to isolate the power supply using an all-pole circuit breaker for the intended current. For information regarding maximum load for externally connected devices. see electrical installation instructions.
6.4 Connecting hot water sensor • Auxiliary modules ⚠⚠ The two separate 24 VAC circuits must never be connected to each other or to protective ground. Hot water sensor PT1000 Connect the hot water sensor to the designated terminal block. The sensor should be positioned a third way up from the bottom in the water heater which is supplied with incoming cold water. See separate manual for the control system. 6.5 6.
6.14 Locations of the switches 7 Brine installation 7.1 Brine pipes and expansion tank • Install a filter (max mesh size 0.7 mm) in the input coolant pipe to protect the unit against foreign particles. • Install the input coolant pipe with all the accompanying components. • Install the output coolant pipe with all the accompanying components. • Supply both the pipes with diffusion sealed condensation insulation.
13 Stop both the pumps and immediately close valve 1 and 2. 14 Open valve 3 and disconnect the filling hoses. 15 Open valve 6 and pressurise the system, and vent via valve 1. Pressurise to max 1.5 bar. 16 Close valve 6. 17 Set switch S1 and S2 to Auto (compressor and brine pump). 18 Clean the strainers after filling. 8 Start up ⚠⚠ The installation may only start operation if the heating system, any hot water tanks and the coolant circuit are filled. Otherwise the pumps can be damaged.
