User manual KARCHER BPP 4500 50

[. . . ] The manufacturer is not responsible for any damages that may occur on account of improper use or wrong operations. The device is meant for use as house water tank. While using the pump for pressure build-up, the maximum supply pressure of 1. 0 bar (pump entry) should not be exceeded. [. . . ] ṇ Caution Pump starts running immediately. 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). illustration  Install the non-return valve. 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. σ Screw on the lid on the filling nozzle. Finish operation  Disconnect the main plug from the socket. 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). When transporting by hand  Lift appliance by the carrying handle and carry it. [. . . ] Pressure is not retained in the system Remedy In order to prevent a repetition, the system should be checked for leaks and sealed. check connections including sealings and control the water outlet. The smallest of leakages can affect the operation adversely. Remove the pre-filter and clean it under flowing water. [. . . ]
