Notice HAYWARD Tristar

« ound it to provide for natural ventilation. The pumps must be installed in a fixed station. The acoustic level of the Hayward pumps is lower than 70 dB (A). Warning: This appliance is not intended for use by persons (including children) with reduced physical, sensory or men- tal capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Necessary arrangements : • Connect the pump to ground • Connect the pump with a H07RN-F cable. • Fit a 30 mA differential protection device to protect people from electric shock caused by a possible break in the electrical insulation. • Provide protection against short-circuiting (the definition of the rating will depend on the value indicated on the motor name plate). • Provide a circuit separation device with a 3 mm opening on all the poles. Single phase electric motor: The single phase motors fitted to our pumps are provided with thermal protec- tion. This protection operates on an overload or in the event of abnormal heating of the motor coil and is reset automatically when the winding temperature drops. Three phase electric motor: Check the running direction of the pump motor (a label is provided on the motor housing to indicate the motor running direction). If so required by regulations and whatever the motor type, in addition to the devices mentioned above, it is also necessary to install a thereto-magnetic protective device calibrated in accordance with the indications on the motor name-plate. The table on page 23 indicates the various characteristics of the motors fitted to our pumps. Electrical connection: Make sure that the power supply voltage required by the motor corresponds to that of the distribution network and that the power supply cables matches the power and current of the pump. All the electric connections of the pump and the possible change of power supply cable must be hand-led by a qualified professional so as to avoid all possible danger. When making these electrical connections, refer to the diagram given under the lid of the motor terminal box. Be sure to check the electric connections are tight and sealed before powering up. The pre-wiring that might be included on some of the pumps must be removed for final connection of the pump to the electric power supply. This pre-equipment is only used for works testing during the manufacturing phases. GB3 STARTING AND PRIMING INSTRUCTIONS Fill strainer housing with water to suction pipe level. Never operate the pump without water. Water acts as a coolant and lubricant for the mechanical shaft seal. Open all suction and discharge valves, as well as air bleed (if available) on filter. (The air that is to be displaced from the suction line must have someplace to go). Turn on power and allow a reasonable time for priming. Five minutes is not unreasonable. (Priming time depends on suction lift and horizontal length of suction piping). If pump will not start, or will not prime, see TROUBLE SHOOTING GUIDE. MAINTENANCE 1. Clean strainer basket regularly. Do not strike basket to clean. Inspect strainer cover gasket regularly and replace as necessary. 2. Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary 3. Keep motor clean. Insure air vents are free from obstruction. 4. Occasionally, shaft seals become damaged or... »
