Symbols in the operating instructions ƽ Danger Immediate danger that can cause severe injury or even death. Warning Possible hazardous situation that could lead to severe injury or even death. Caution Possible hazardous situation that could lead to mild injury to persons or damage to property. [. . . ] ρ The appliance may be used by children over the age of eight and individuals with limited physical, sensory or cognitive abilities or lack of experience and knowledge if they are under supervision or were instructed regarding the safe use of the appliance and understand the resulting risks. ρ Supervise children to prevent them from playing with the appliance. Prerequisites for the appliance's stability Caution Create stability for the appliance prior to all work on or with the appliance to prevent accidents or damage. € The stability of the appliance is warranted when it is placed onto an even surface. 14 EN – 2 Operation Please follow the safety instructions before start-up!Wait till the pump sucks in and pumps uniformly, then shut the gate valve in the pressure pipe. The pressure switch deactivates the motor when the shut-off pressure is reached. The storage boiler is now full; the domestic water supply system is ready for operation. If there is a lack of supplied water, the switch-off pressure is not reached; the pressure switch cannot shut off the appliance, the water in the pump head will then heat up enough to damage the appliance. In models BPP 4000/48 and BPP 4500/50, the supplied power is interrupted by a thermal switch if there is an overheated condition. The supplied power is switched back on after the appliance has cooled off. We recommend installing a dry run protection unit to regulate the lack of water situation.

Illustration  Secure device against slipping off (fix it with screws, if needed). σ Connect the vacuum-proof suction hose with integrated backflow stop on the suction side. (available as optional accessory)  Connect the pressure side for noise reduction to the pressure pipe via flexible hose. Illustration  To simplify the subsequent discharge and pressure release of the system, we recommend that a release cock be installed between pump and suction hose / non-return valve. (not included in delivery) Illustration  Unscrew the lid of the filling nozzle and fill in water till it overflows. EN – 3 15 Maintenance and Care ƽ Danger Pull out the mains plug before doing any maintenance or cleaning jobs. After opening the filling or drain lid or before separating the pipes, open the locking valve on the pressure side and empty the system via the drain tap (available in plumbing stores). Transport Caution In order to prevent accidents or injuries, keep in mind the weight of the appliance during transport (see Specifications). [. . . ] 0 Pressure compensating hose 3/4“ (19mm), 1m Troubleshooting ƽ Danger To avoid risks, all repairs and replacement of spare parts may only be carried out by authorized customer service personnel. First pull out the plug from the mains before carrying out any tasks on the machine. Fault Pump runs but does not transport Cause Air in the pump Air does not come out on the pressure side Power supply interrupted Thermal protection switch in the motor has switched off the pump as it was overheated. Remedy Refer to Chapter "Preparation" Figure E Open tap on pressure side Check fuses and electrical connections Pull out the mains plug, let the pump cool down, clean the suction area, prevent dry running Pump does not run or suddenly comes to a standstill during operations 18 EN – 6 Fault Pump switches itself off and back on (BPP 4000/48 and BPP 4500/50) Motor starts up immediately after switch off Cause Thermal protection fuse has switched the pump off to protect from overheating or turned it back on after it has cooled off.
