SIGNAL WORD Description of the hazard Consequence of ignoring the warning • Action to avoid the hazard. 4. Installing the product English (US) The hazard statements are structured in the following way: 4.1 Location The product can be installed both indoors and outdoors. Use a suitable cover to protect the product from direct sunlight, rain or snow. Please observe the following: 2.
4.2.2 Connecting the pipe system WARNING Install the product so that it is not stressed by the pipe system. Electric shock Death or serious personal injury ‐ Switch off the power supply before you start any work on the product.Make sure that the power supply cannot be switched on accidentally. Pipe dimensions: • The diameter of the inlet pipe must be larger than 1 inch, if the inlet pipe is longer than 32.8 ft (10 m), or if the suction lift exceeds 13.1 ft (4 m).
English (US) 4.2.2.1 Maximum system pressure Make sure that the system in which the pump is installed is designed for the maximum pump pressure. TM058227 The maximum inlet pressure depends on the feet of head at the actual duty point. The sum of the inlet pressure and the feet of head must not exceed the maximum system pressure. We recommend installing a pressure-relief valve to protect the pump so that the outlet pressure does not exceed the maximum system pressure. Related information 10.
We recommend that you follow the installation examples. Valves are not supplied with the pump. 4.2.3.1 Suction from a tank 7 4 3 4 1 1 2 5 3 2 3 7 5 6 Pos. Description 6 Pos.

4.3.2 Connecting to the power supply WARNING WARNING Electric shock Death or serious personal injury ‐ Switch off the power supply before you start any work on the product. Make sure that the power supply cannot be switched on accidentally. Electric shock Death or serious personal injury ‐ Disconnect the main switch prior to electrical work. ‐ Assume all wires are live. Use an electrical tester to confirm the power is off at each wire.
Follow these steps to connect a power cable to the product: 1. Loosen the nut on the top cover of the pressure switch. 2. Lift up the pressure switch cover and set it aside. 3. Inside the pressure switch, gently push aside the factory wires. Do not disconnect them. 4. Locate the open knockout in the metal plate inside the pressure switch. 5. In the knockout, install a clamp-type fitting designed for connecting a power cable. 6. Loosen the screws on the clamp. 7.

English (US) 4.3.3 Setting the voltage converter WARNING Electric shock Death or serious personal injury ‐ Do not pull the voltage switching plug by the wires. To avoid damage, only use a firm hand grip around the voltage switching plug. 1. Check the voltage indicated on the side of the voltage converter. 2. Turn the indicator so that the desired voltage (115 V or 230 V) points towards the side with the "M" lock catch. 3.
5.1 Priming the product English (US) 5. Startup of the product WARNING Electric shock Death or serious personal injury ‐ Do not use the product for cleaning and other maintenance of swimming pools or similar places if there are people in the water. CAUTION Always tighten the priming plug by hand. 1. Unscrew the priming plug. 2. Fill the pump with water. 3. Refit the priming plug and tighten by hand.
Pos. Description After installing the product, do the following: 5 Base plate 1. Open all isolating valves. Make sure that the water supply is sufficient on the inlet side of the pump. 6 Drain plug 2. Turn on the power supply to the pump, and the pump will start. If there is a suction lift, it can take up to five minutes before the pump delivers water. This period depends on the length and diameter of the inlet pipe. 7 Inlet connection, 1" NPT 3.

WARNING Electric shock Death or serious personal injury ‐ Switch off the power supply before you start any work on the product. Make sure that the power supply cannot be switched on accidentally. 8.1 Draining the pump To drain the JP PS pump: 1. Unscrew the drain plug using a screwdriver. 2. Let the water flow out of the pump. 3. When the pump is empty, refit the plug by hand. 1 WARNING Chemical hazard Death or serious personal injury ‐ Make sure that the product has only been used for water.
9.3 The motor turns with difficulty 9.1 The motor does not start and makes no noise Cause Insufficient voltage or blockage Cause Power supply failure Remedy • Check the voltage which may be insufficient. Correct any errors. Remedy • Check the electrical connections. If the fault is repeated immediately, this means the motor is short circuiting. • Check whether any moving parts are scraping against fixed parts. Eliminate the cause of the scraping. • Check that the motor is live.
English (US) 9.7 The pump supplies insufficient flow Cause Insufficient intake due to blockage or worn parts Remedy • Blocked foot valve. Clean the foot valve. • The impeller is blocked or worn. Remove the blockage or replace the worn parts. • The diameter of the intake pipe is insufficient. Replace it with a larger diameter pipe. 9.
