INSTALLATION AND OPERATING INSTRUCTIONS HAYWARD SKIM-MASTER SP1070-1071 SERIES AUTOMATIC SURFACE SKIMMER

Hayward Skim-Master Automatic Surface Skimmer for concrete pools

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, uni-body 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 main drain-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 can easily make the skimmer of your choice for commerical application. Refer to illustrations for details.

BASIC SKIMMER UNIT FLOW ADJUSTMENT BASIC SKIMMER UNIT FLOW ADJUSTMENT. For full flow, move FloControl 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. Auxiliary Port Feature. To remove "knock-out," drill a small pilot hole in the center of the knock out. Then, using a drill up to but not exceeding 3/4", remove the remaining material.

 

SKIMMER INSTALLED WITH MAIN DRAIN CONN. AND FLOAT VALVE/SAFETY BYPASS SKIMMER INSTALLED WITH MAIN DRAIN CONN. 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 main drain line. Flow is balanced by means of the FloControl Trimmer Plate under the float valve assembly. 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 main drain 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.

 

SKIMMER INSTALLED WITH EQUALIZER VALVE AND FLOAT VALVE KIT SKIMMER INSTALLED WITH EQUALIZER VALVE AND FLOAT VALVE KIT 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.


TO SWEEP/BRUSH: To divert all suction to the main drain, 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 back up. 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 main drain port for maximum efficiency.

TO VACUUM: Select one convenient skimmer and remove cover, basket and float valve assembly. Screw hose adapter into pump outlet. Fill vacuum hose with water and insert over hose adapter. Throttle down flow from other skimmer(s) until
desired suction is obtained through vacuum.

LOCATION OF SKIMMERS: To obtain the most effective skimming action over the entire pool surface, locate the skimmers relative to the prevailing wind and drift, shape of pool and water circulation pattern. The use of directional inlet fittings will ensure the proper circulation pattern,

PVC CONNECTIONS: The Hayward SP1070/1071 Series Skimmers are molded of ABS and .. require the appropriate glue for connecting with PVC.
