Hayward SP1070 Automatic Surface Skimmer Models: SP1070-SP1071 - Page 4

INSTALLATION INSTRUCTIONS: The SP1070/1071 Series Skim-Master is a rugged and versatile automatic surface skimmer molded of non-corrosive ABS for residential or commercial installations. The SP1070/1071 is the basic skimmer unit, featuring totally corrosion-proof, unibody construction, adjustable deck collar and round access cover, self-adjusting weir, large debris basket, auxiliary port (SP1071 only), and multiple plumbing connections for easier installation. The optional SP1070FV Float Valve/By-Pass Assembly installs easily in the SP1070 / 1071 basic skimmer to provide a suction outlet thru-skimmer system and an auto safety by-pass for low water conditions. Where required for commercial installations, the SP1070FVEKIT Float Valve and Equalizer Check Valve Kit and cover WG1070C can easily make the skimmer of your choice for commercial application. Refer to illustrations for details. BASIC SKIMMER UNIT FLOW ADJUSTMENT For full flow, move Flo-Control Slide Plate to full open. To adjust flow, move Slide Plate to desired position over pump outlet. TO VACUUM Remove cover and basket. Screw hose adapter into pump outlet. Fill vacuum hose with water and insert over hose adapter. Or use optional SP11063 Skim-Vac over basket vacuum plate. SKIMMER INSTALLED WITH SUCTION OUTLET CONNECTION AND FLOAT VALVE / SAFETY BYPASS When used with the SP1070FV Float Valve, water is drawn by pump suction from the surface of the pool and from the suction outlet line. Flow is balanced by means of the Flo- Control Trimmer Plate under the float valve a sse m b l y . If obstruction to flow or evaporation occurs, causing a significant reduction of flow over the weir, the float will automatically snap shut. This diverts all flow to the pump from the suction outlet line and prevents possible air lock. When the pump is shut off, the float will rise back to the top of the float valve assembly, allowing for normal operation if the flow or water level condition has been remedied. TO SWEEP / BRUSH To divert all suction to the suction outlet, simply hold the weir up above normal operating level and allow the float to "snap" shut. Or, lift out float valve assembly, close flo-control plate and replace. To reset float after sweeping, turn off pump for 10-15 seconds and allow float to rise. WARNING: To prevent hair or body entrapment, a suction outlet fitting conforming to ANSI/ASME A112.19.8 must be installed. TO VACUUM Remove cover, basket and float valve assembly. Screw hose adapter into pump outlet. Fill vacuum hose with water and insert over hose adapter. Or use optional SP11063 Skim-Vac. If Skim-Vac is used, block off suction outlet port for maximum efficiency. SKIMMER INSTALLED WITH EQUALIZER VALVE AND FLOAT VALVE When using SP1070FVEKIT for commercial application, the Equalizer Check Valve installs over front port, and is used in conjunction with the Float Valve. If water level drops below skimmer opening, or if skimmer flow is obstructed, the float will automatically snap shut and the equalizer valve will open. This diverts all flow to the pump from the equalizer line and prevents airlock in the pump. When the pump is shut off, and the water level condition is corrected, the float will rise and the equalizer valve will close, allowing normal skimming operation when the pump is restarted. WARNING: To prevent hair or body entrapment at the skimmer equalizer, a equalizer wall or a suction outlet fitting conforming to ANSI/ASME A112.19.8 must be installed.
