Page 3: General Information
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®... -
Page 4: Designated Use
Only use PAW accessories with the solar station. Improper usage excludes any liability claims. Under the influence of solar radiation, the collectors will heat up considerably. -
Page 5: Safety Instructions
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]. - Page 6 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.

Page 7: Mounting And Installation [Specialist]
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 8 Mounting and installation [specialist] Accessories: compression fitting 1. Push the union nut ② and the cutting ring ③ onto the copper pipe ①. The pipe must protrude at least 3 mm from the cutting ring in order to ensure the force transmission and the sealing.
- Page 9 Mounting and installation [specialist] 1. Remove the station from the packaging. 2. Take off the thermometer handles and remove the insulating front shell. 3. Copy the mounting holes of the wall bracket to the mounting surface. 4. Drill the holes. 5.

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). -
Page 11: Flushing And Filling The Solar Circuit
Commissioning [specialist] 4.1 Flushing and filling the solar circuit Make sure not to wash dirt particles that may be present in the solar installation into the expansion tank. To do so, it may be necessary to disconnect the expansion tank during flushing and filling and to use only flushing and filling stations that are equipped with suitable microfilters. - Page 12 Commissioning [specialist] Functions of the fill and drain valve within the safety group Position Function Position "closed" (station in operation): Fill and flush circuit is closed. Pressure gauge indicates system pressure. Position "open" (fill and flush processes): Fill and flush circuit is open. Pressure gauge indicates pressure. Position "maintenance"...

Page 13: Preparations Before Flushing
Commissioning [specialist] 4.2 Preparations before flushing 1. Turn both check valves to the operating position "Z" and open the ball valves in the flow and return [1.2|5.2]. 2. Close the shut-off valve [3.1]. This guarantees that the dirt particles that may be still present will be washed out of the system and will not access the circuit again. -
Page 14: Flushing And Filling
Commissioning [specialist] 4.3 Flushing and filling 1. Put the flush and fill station into operation. 2. Flush the collector system for at least 15 minutes. 3. In order to eliminate the air from the storage tank, open the shut-off valve [3.1] and close the ball valve in the flow [5.2]. -
Page 15: Adjustment Of The Solar Installation
Commissioning [specialist] WARNING Risk to life and limb due to electric shock! Prior to commencing electrical work on the controller, pull the mains plug! ► Only after completing all work, plug the mains plug into a socket. This avoids ► an unintentional start of the motors. -
Page 16: Maintenance [Specialist]
Maintenance [specialist] 5 Maintenance [specialist] 5.1 Replacement / adjustment of the pressure gauge 1. Switch off the controller and secure it against being switched on again. 2. Make sure that the valve [1.4] is closed with cap. 3. Turn the valve [1.4.] in position "maintenance" by removing the stop screw, see chapter 4.1. -
Page 17: Draining The Solar System
Maintenance [specialist] 5.2 Draining the solar system 1. Switch off the controller and secure it against being switched on again. 2. Turn the check valves to position "A" and open the ball valves in the flow and return. Check valve is operating, flow only in flow 3. -
Page 18: Deinstallation
Maintenance [specialist] 5.3 Deinstallation 1. Drain the solar installation as described above. 2. Disconnect the pipe connections to the solar installation. 3. Loosen the screws of from the mounting plate in order to remove the solar station from the wall bracket. -

Page 23: Function Of The Check Valves [Expert]
Function of the check valves [Expert] 8 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 24 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.
