Operating principle of heat pumps Heat pumps operate on the principle of a refrigerator: the same technology, only with the opposite effect. The refrigerator extracts heat from foods, which is released into the room through fins on the back. The heat pump extracts heat from our environment: air, earth or ground water. The extracted heat is conditioned in the unit and supplied to the heating water. Even when it is extremely cold outside, the heat pump draws enough heat to heat a house.
The cooling function is based on the principle of passive cooling. An existing low temperature level is mixed to a temperature above the dew point and transferred to the heating medium by means of a heat exchanger. The heat pump remains switched off during cooling; only the circulating pumps for the heating circuit and the heat source are in operation. The cooling power depends on the heat source temperature, which varies seasonally.
Care of the unit The outer surfaces of the unit can be cleaned with a damp cloth and household cleaning products. Do not use cleaning or care products that contain abrasives, acids and/or chlorine. Such products would destroy the surfaces and could also damage the technical components of the unit. Maintenance of the unit The cooling circuit of the heat pump requires no regular maintenance.

Do not tilt the module box more than a maximum of 45° (in any direction). If it is not possible to transport the unit to the final installation location using a lifting truck, you can also transport the unit using a hand truck. Caution. Danger! Several people are required to transport the unit.
Proceed as follows to mount the feet on the unit: • Tip the unit slowly and carefully to one side. Secure unit in raised position so that it cannot accidentally tip back into the original position. Caution! 1 Recessed grips 2 Carrying strap Caution. Never use components and hydraulic connections on the unit for purposes of transport. Hands and fingers could be crushed during the following tasks! • Mount one foot each on the front and back of the unit.
Installation of the module box The entire cooling circuit of the heat station is contained in the module box. Caution. Do not tilt the module box more than a maximum of 45° (in any direction). Place module box in front of the unit. 1 Unit 2 Plug for electrical connection 3 Front edge of bottom of unit 4 Module box Raise module box, push it further into the unit and lower the box as soon as the rubber feet contact the corresponding stops of the centering plate.
Caution. Once the module box has been placed in the unit, it can no longer be transported. Installation of the hydraulic connections Caution. The heat source system must be designed according to the specifications of the heat pump guide. Heat pump guide and “Hydraulic connection” instructions. Notice. Check to make sure that the diameters and lengths of the pipes for the heating circuit and the heat source are sufficiently dimensioned.
Place a bleeder at the highest point of the heat source in the heat source outflow. Screw angle ball valves of the vibration decouplers to the heating circuit connections. If necessary, place a bleeder at the highest point of the heat source in the heat source inflow. Place a bleeder at the highest point of the heating circuit in the heating circuit outflow (forward flow). If necessary, place a bleeder at the highest point of the heating circuit in the heating circuit inflow (return flow).
Connecting the module box to the heat source Insert included plastic rosettes in the holes. Vibration decouplers are included for the connection to the pipes of the heat source. They must be installed in order to prevent damage from vibrations to the pipes. The pipes of the heat source can be connected either on the right or left side of the unit. Insert vibration decouplers in unit from outside and guide them inside the unit to the connections on the module box.
Connection of the vibration decouplers on a unit without cooling function Connection of the vibration decouplers on a unit with cooling function Arrange vibration decouplers in a quarter circle in the unit to the connections on the module box. Arrange vibration decouplers in a quarter circle in the unit.
Screw vibration decoupler (with elbow) of heat source inflow to provided connecting pipe. Use seals from the extra box. Connecting the compact unit to the heating circuit The connections for the pipes of the heating circuit and the hot water supply are located on the top of the unit. 1 Vibration decoupler without elbow 2 Vibration decoupler with elbow Screw included angle ball valve to vibration decoupler (without elbow) of heat source outflow. Use seals from the extra box.
Opening the angle ball valves on the module box Open all angle ball valves on the module box by turning them 90° counter-clockwise. Safety component The safety component for the heating circuit is in the extra box. Mount the safety component on the connection provided on the top of the unit. Expansion vessels The expansion vessel of the heat source is included in delivery and must be installed with the connection assembly.
Electrical connections Watch out for retaining nose. Plugs must be mounted for easy movement. Observe the following when performing all work: Danger! Danger of fatal injury due to electric current! Electrical connections may be installed only by qualified electricians. Danger! Observe the relevant EN, VDE and/or applicable local safety regulations during the installation and during all electrical work.
For further information, see the adhesive label on the electric heating element. 1 Adhesive label on electric heating element After completion of all electrical installation work, close the switch cabinet inside the unit.
Rinsing and filling the unit Danger! Danger of fatal injury due to electric current! Disconnect unit from power supply. 6 Overflow valve 7 Electric heating element 8 Rinsing ball valve 9 Electrical switch cabinet 10 Sensor for hot water tank 11 Hot water tank service hole (under Styrofoam cover) 12 Hot water tank emptying valve Proceed as follows: Open unit if this has not already been done. Transport to installation location, Cleaning and rinsing of unit components .
Rinsing and filling the hot water and heating water circuits Use the rinsing ball valves for rinsing and filling. Caution. Do not exceed a pressure of 2.5 bar. Move lever on 3-way switching valve for the heating circuit/hot water to the right (= normal position). Picture shows operating condition at time of delivery. Contamination and deposits in the heating circuit can cause malfunctions. Caution.
Bleeding The unit is bled automatically when the bleeder (black cap) of the safety component of the heating circuit is open. If the heating circuit is filled or emptied, the bleeding valve of the safety component opens. Bleeding the circulating pump of the heat source Unscrew front panel of module box. Loosen the screw-on cap in the middle of the circulating pump for the heat source.
• With the circulating pump running, turn wrench counter-clockwise until the regulator of the servomotor is at 50%. Turning the regulator to 50% means an even mixture in the 3-way mixing valve from A and B to AB. Adjust mixing valve. Use the wrench included in the scope of delivery. Alternatively: Use a size 6 Allen wrench. • Insert wrench in the servo-motor. Reset servo-motor of the mixing valve to automatic as soon as bleeding is completed. Notice. Push switch on the bottom of the servomotor forward.
Overflow valve Set the overflow valve so that the spread between the forward and return flow is ≤ 10K (set at the factory to 200 mbar and sealed by paint). Insulating the hydraulic connections Notice. Insulate the heating circuit and the heat source according to local applicable standards and directives. The angle ball valves of the connections on the module box must be opened. Check seals of all hydraulic connections. Conduct pressure test.
Installation of the control element Suspend the control element in the two square recesses in the front panel. Lay the control cable for the regulator from the inside of the unit through the sleeve in the front panel to the outside. Mounting and removal of the screen First, insert the screen at the bottom in the slot provided on the front panel of the heat station. First, insert snap-in lugs on one side of the screen from bottom to top in the slots provided on the front panel of the unit.
Notice. To remove the screen, release the snapin lugs in the reverse order, i.e. from top to bottom, without the use of tools. Caution. The snap-in lugs have a tight fit. Press firmly from the side against the screen toward the middle, so that the snap-in lugs do not break off.
