Hayward Pro-Series Model: S166T - Page 1

IS166TN2-00 Your Hayward S166T high-rate sand filter is a high performance, totally corrosion-proof filter that blends superior flow characteristics and features with ease of operation. It represents the very latest in high-rate sand filter technology. It is virtually foolproof in design and operation and when installed, operated and maintained according to instructions, your filter will produce clear, sparkling water with only the least attention and care. HOW IT WORKS Your filter uses special filter sand to remove dirt particles from pool water. The sand is loaded into the filter tank and functions as the permanent dirt removing media. The pool water, which contains suspended dirt particles, is pumped through your piping system and is automatically directed by the patented filter control valve to the top of the filter tank. As the pool water is pumped through the filter sand, dirt particles are trapped by the sand bed, and filtered out. The cleaned pool water is returned from the bottom of the filter tank, through the control valve and back to the pool through the piping system. This entire sequence is continuous and automatic and provides for total recirculation of pool water through your filter and piping system. After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This means it is time to clean (backwash) your filter. With the control valve in the backwash position, the water flow is automatically reversed through the filter so that it is directed to the bottom of the tank, up through the sand, flushing the previously trapped dirt and debris out the waste line. Once the filter is backwashed (cleaned) of dirt, the control valve is manually resequenced to Rinse, and then Filter, to resume normal filtering. INSTALLATION Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic adapters, are required to install and/or service filter. 1. The filter should be placed on a level concrete slab, very firm ground, or equivalent as recommended by your pool dealer. Position the filter so that the piping connections, control valve and winter drain are convenient and accessible for operation, servicing and winterizing. 2. Your filter is supplied complete with an optional pump mounting base which is pre-drilled for use with Hayward Power-Flo LX series pumps. The pump to filter connecting hoses supplied will accommodate Power-Flo LX pumps used with the mounting base, and Max-Flo or Super Pump installed at surface level. To connect pump to filter: a. Screw straight adapter, using Teflon pipe sealant tape or Permatex No. 2, securely into pump discharge. (Do not overtighten.) b. Screw elbow adapter, using Teflon pipe sealant tape or Permatex No. 2, securely into opening in control valve marked PUMP. (Do not overtighten.) Elbow should point just over RETURN opening. 33" (84 cm) PUMP MOUNTING BASE (S164C)
