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. (For pressure details see chapter on technical specifications)

Preparing the Appliance
Illustration Before start-up, check the pressure of the air filling in the storage boiler. 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

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

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. [. . . ]
