Tap water booster pump When installing the booster pump, be sure to install it horizontally or vertically as shown in the "Installation Method". The direction of the water flow should be consistent with the direction of the arrow on the pump body, and should be installed at the lowest position from the water level. For ease of use and service, a valve should be installed on the pump inlet line. When the suction level is lower than the pump impeller or the pump shaft around the pump when the check valve should be installed, the outlet connected to a tee for water diversion, in the first use should be filled with water pump and Tighten the plug. Pipe connections should be tight, especially the inlet pipe can not leak otherwise it will reduce the pump lift or pumping on the water. Pump cavity is not water, do not even a long time even turn, so as not to damage the seal. The motor coil is equipped with a safety protector. When the pump fails or does not pump water, the motor can automatically open when the temperature rises more than the specified value. After the motor temperature rises, the motor can resume operation automatically. The booster pump motor is a capacitor-operated motor. When the pump is shipped, the direction of rotation has been adjusted. If it is necessary to replace the capacitor or re-connect the motor, please press the arrow mark on the pump body. To ensure safe operation, you must use a three-pin safety socket with a grounding wire. Pump leakage found immediately shut down to prevent internal leakage, if the connection with the motor leakage should be replaced mechanical seal. Check if the power is on. Use the power supply voltage is consistent with the working voltage of the pump. As above a, b normal; please remove the pump, open the pump cover, remove the foreign body in the pump, and then install the pump cover, tighten up to normal. When the pump can not pump water, the pump is installed on the water pipe. If the water level is below the plane (horizontal installation) or the center line (vertical installation) of the pump impeller, the power should be turned off at this time. When the water level of the water tank rises more than Impeller plane or centerline, then turn on the power, so as not to damage the mechanical parts (automatic type without electricity). When the pump is used to pump well water, please check if the water inlet pipe leaks; if there is not enough water in the pump chamber, it should be filled with water; if the suction stroke is too high, adjust it properly. Check the import and export pipe diameter is too small or blocked. Automatic use of a period of time, may appear automatic failure phenomenon, mainly in the water pipe rust and other metal products from long-term precipitation, turn off the power after removing the switch, unscrew the screw above, remove the plastic sheet to be cleaned, and then , According to the original reset, debugging normal, you can re-use.
