[_eck Valve I Steel Drive Pipe Drive coupling Well point Liven poi!It For a pump at sea level mounted directly over the well, be sure the total lift from the pumping water level to the pump does not exceed 20 feet. This will be less ff the pump is off set from the well. The maximum lift of any pump decreases at the rate of about 1" less lift for every 1,000 feet of elevation above sea level. For example, at Denver, Colorado (Elev. 5,000') the pump loses five feet of lift. The maximum depth from which it would pump water would therefore be 15 feet. Well Seal Plastic Pilse Pipe " and Strainer 5111293 Dug or Cased Well Figure 2B PUMP/TANK INSTALLATION Pump NOTICE: Use Teflon tape supplied with the pump or Plasto- Joint Stik' for making all pipe-thread connections to the pump itself. To avoid stress-cracking, do not use pipe joint compot_nds on the pump. 1. Wrap male pipe threads being attached to pump with one or two layers of Teflon tape. Cover entire threaded portion of pipe. 2. Do not overtighten threaded fittings in the plastic pump. Be sure you do not try to tighten joint past thread stop in pump port! 3. If leaks occur, remove fittings, clean offold tape, rewrap with two to three layers of tape and remake the connection. If joint still leaks, replace the fittings (fittings may be undersized). 4. Be sure to support all piping corlnected to.,,th.€ System. _Lake Chemical Co., Chicago, Illinois Horizontal Piping from Well to Pump When the pump is offset more than 25 feet from the well, horizontal suction pipe size should be increased to reduce friction losses. Never install a suction pipe that is smaller than the suction tapping of the pump. Figure 2A INSTALLATION 1-1/4" 1-1/2" 2" Up to 25 Ft. 25 to 50 Ft. 50 to 200 Ft. Discharge Pipe Sizes When the pump is some distance from the house or point of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction. 1" 1-114" 1-1/2" Up to 25 Ft. 25 to 100 Ft. 100 to 800 Ft. Tank Tanks are pre-charged with 40 PSI air pressure at the factory. Your tank requires an air ch.arge of 40 pounds per square inch (PSI) for proper operation; check tank pressure with tire gauge to determine flair charge needs adjustment. Tank pre-charge should be checked annually; see instructions at right. In areas where the temperature is high for long periods of time, the tank pre-charge pressure may increase. This may reduce the tank drawdown (amount of water available per cycle). If this occurs, reduce the pre-charge pressure to two PSI below the pump cut-in setting of the pressure switch (normally to 38 PSI). It is necessary to flush all air out of the piping system and water reservoir portion of the pre-charged tank. This is re quired on new installations, pumps requiring repriming and pumps that have been disassembled for service. Do this as fonows: 1. Open faucets furthest from tank and allow pump to operate. 2. Air in the system will cause a sputtering flow; allow faucets to run until you have a steady, air free stream. 3. Open and close faucets repeatedly until you are sure all air has been removed. 4. If stream does not become steady, air may be leaking into the system; check for leaks in the piping on the suction side of the pump. NOTICE: To prevent waterlogging, check tank air charge annually. To Check Tank Air Charge If drawdown (amount of water available per cycle), decreases significantly, check as follows: 1. To check air charge in tank, shut off electric power to pump, open faucet near tank, and drain completely. 2. At the air valve in top of tank, check air pressure with standard tire gauge. Air pressure should be the same as pump pressure switch cut-in setting (40 PSI). 3. If the air pressure is below 40 PSI, add air to the tank. Use an air compressor or a portable air storage tank. 4. Use soap or liquid detergent to check for air leaks around air valve. Continuous bubbling indicates a leak. If necessary, install new core in air valve. This is the same as those used for automobile tubeless tires. 12 34 5 1. Tank nearly empty -air expands filling area above cut off setting of pressure switch. vinyl separator. 4.
