General Information 1 General Information Carefully read these instructions before installation and commissioning. Save these instructions in the vicinity of the installation for future reference. 1.1 About these instructions These instructions describe the installation, commissioning, function and operation of the solar station SolarBloC®.
Only use PAW accessories with the solar station. Improper usage excludes any liability claims. *Controller optional Under the influence of solar radiation, the collectors will heat up considerably.
Safety instructions 2 Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist].

Safety instructions CAUTION Personal injury and material damage due to overpressure! Closing both ball valves in the primary circuit will separate the safety group from the heat exchanger. A rise in temperature in the storage tank may result in high pressures, which may lead to personal injury and material damage! Only close the ball valves for service and maintenance.
Mounting and installation [specialist] 3 Mounting and installation [specialist] NOTICE Material damage due to high temperatures! Since the solar fluid near the collector can be very hot, the group of fittings must be installed at a sufficient distance from the collector field. It may be necessary to install an intermediate tank in order to protect the expansion tank.
Page 9
Mounting and installation [specialist] 1. Remove the station from the packaging. 2. Remove the insulating front shell. 3. Only for version with Wilo Maxo pump / Grundfos Solar PML pump: Mount the enclosed safety group for completion and prior to commissioning.

Commissioning [specialist] 4 Commissioning [specialist] Please observe the following safety instructions regarding the commissioning of the station: WARNING Risk of burning and scalding! The valves and fittings may heat up to more than 100 °C. Therefore, do not clean or fill the system when the collectors are hot (intense sunshine).
Commissioning [specialist] 4.1 Flushing and filling the solar circuit The fill and drain valves necessary to flush and fill the installation are integrated in the solar station. Make sure not to wash dirt particles that may be present in the solar installation into the expansion tank.

Commissioning [specialist] Airstop The Airstop (vent valve with manual bleeder) is used to vent the solar system. To ensure a perfect venting of the solar circuit, the flow velocity must be at least 0.3 m/s in the flow line. Pipe diameter [mm] Flow rate at 0.3 m/s l/min ∅...
Commissioning [specialist] 4.2 Preparations before flushing The solar circuit is flushed in the direction of flow. 1. Disconnect the expansion tank from the solar system. Please observe the instructions of the manufacturer! 2. Turn the check valve in the flow ball valve [5.2] into operating position (0°, see chapter 4.1).
Page 17
Commissioning [specialist] 3. Slowly open the return ball valve [1.2] (0°, see chapter 4.1) to vent the pump section. 4. Close the drain valve [3.2] while the filling pump is running and increase the system pressure to maximum 5 bars. The system pressure is displayed on the pressure gauge.

Commissioning [specialist] WARNING Risk to life and limb due to electric shock! Check whether the sensors and pumps have been connected to the ► controller and the controller housing is closed. Only then, the mains plug of the controller can be plugged into a socket. 10.
Commissioning [specialist] 4.4 Setting the solar installation 1. Set the desired revolution speed of the solar pump depending on the required flow rate. If necessary, the flow rate can be reduced by the ball valve [3.1] (only necessary if the pump is not speed-controlled).

Commissioning [specialist] Source of image: Resol If another system is selected, it may be necessary to connect further sensors and switching elements. Please observe the separate instructions of the controller! The controller first runs through an initialisation phase, subsequently the commissioning starts in which the most important settings are made according to the following schema: Source of image: Resol For for further settings or modifications related to the system, the options or the functions, please...
Commissioning [specialist] 4.6 Heat quantity measurement The controller offers the possibility to carry out a heat quantity measurement in two different ways: with flow rate sensor or without flow rate sensor (fixed set value). The product has an analogue display element to measure the flow rate without an electrical connection to the controller.
Maintenance [specialist] 5 Maintenance [specialist] WARNING Risk of burning and scalding! The valves and fittings and the solar fluid can have temperatures of more than 100 °C. The solar fluid may escape as vapour and result in scalding. Perform maintenance work only when the collector temperatures are ►...
Maintenance [specialist] 5.2 Draining the solar system 1. Switch off the controller and secure it against being switched on again. 2. Open the check valves in the flow and return ball valve [5.2|1.2] by turning them into position 45°, see chapter 4.1.
Maintenance [specialist] 5.3 Deinstallation 1. Drain the solar installation as described in the previous chapter. 2. Disconnect the pipe connections to the solar installation. 3. To remove the solar station from the mounting plate, pull out the clip springs laterally with a screwdriver. 4.

Function of the check valves [Expert] 9 Function of the check valves [Expert] The check valves in this station prevent unwanted gravity circulation within their range of use. The functioning of the check valves depends: on the system height ● on the temperature difference between storage tank and collector ●...
Page 36
Function of the check valves [Expert] Do you need to know it exactly? The density of the solar fluid strongly decreases with increasing temperature. In systems of high system heights and with large temperature differences, the difference in density causes gravity circulation.
