LoBoy 1, 2, 3 & 4 LoBoya > - NOTICE: VENT HOLE FOR CHECK VALVE - PAGE 2 •Effluent systems should specify that pumps shoulcThot handle solids exceeding five flTghts Inch (%") in order to prevent large solids from entering leeching fields, mound systems and etc. Where codes permit, sewage pumps can be used for effluent systems. ^ PREINSTALLATION CHECKLIST — ALL U$^ALLATiONS 1. Inspect your pump. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using. ' 2. Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference. 3. Make sure there Is a property Installed ground fault Inter rupter available. All pumps are furnished with provisions for prcper grounding to help protect you against the possibility of electrical shock. (SEE WARNING BELOW) 4. Make certain thrc the ground fault interrupter receptacia is within reach of the pump's power supply cord. DO NOT USE .*.N EXTENSION CORD. Extension cords that are too long or too tight do not deliver sufficient voltage to the purr.p motor. But, more Important, they could present a safety hazard if the insulation were to become damaged or the connection ends were to fall into the sump. 5. Check to be sure your power source is capable of handling the voltage requirements of the motor, as indicated on the pump name plate. 6. Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers of proper capacity. A separate branch circuit is recommended, sized according to th National Elec trical Code for the current shown on the pump name plate. 7. Testing for Ground. As a safety measure, each electrical outlet should be checked for ground using an Underwriters Laboratory Listed circuit analyzer which will indicate if the power, neutral and ground wires are correctly connected to your outlet. If they are not. call a qualified licensed electrician. 8. WARNING: The installation of automatic pumps with mercury float switches or non-automatic pumps using auxiliary mercury float switches is the responsibility of the installing party and care should be taken that the tethered float switch will not hang up on the pumping apparatus or pit peculiarities and is secured so that the pump will shut off. It is recommended to use rigid piping and fittings andlhe pit be 18" or larger is diameter. 4.1 9. Information - hole purpoM. It is necessary that all submersible sur^^-i -*117 and sewage pumps capable of handling various sues of solid waste be of the bottom intake design to reduce clogging and seal failures. If a check valve is incorporated in the installation, a vent hole (approx. 3/16") must be drilled ir. the discharge pipe below the check valve and pit cover to purge ine unit of trapped air. Trapped air is caused by agitation and/or a <y basin. This vent hole should be checked periodically for clogging. The LoBoy 1. 2. 4 & 20 pumps have a built-in vent CAUTIONS A WARNINGS CAUTION: Installation and checking of electrical circuits and hardware ohould only be performed by a qualified licensed electrician. CAUTION: Repair and service should be performed by HI-LO Industries Authorized Service Station only. CAUTION: Effluent pumps are not designed or intended for use to handle sewage. CAUTION: Maximum continuous operating temperature for standard model pumps must not exceed 130“F. (54* C.) WARNING: FOR YOUR PROTECTION ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock. DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE GROUND PIN. The 3-prong plug mutt be inserted into a mating 3-prong ground fault interrupter receptacle. If the installation does not have such a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable local codas and ordinances.

Surve> ..rs 8^ Landscape Architects September 22, 1987 Mr. James Brownlee 250 Cygnet Place Long Lake, MN 55356 Dear Mr. Brownlee; At your request, a site evaluation to determine soil suitability for a replacement on-site sewage treatment system was performed at Lot 9, Block 3, Swan Lake Addition in the City of Orono, Minnesota. Standard methods of percolation testing were employed. Elevations are relative to an assumed elevation of 100.0 feet based at the top of the 12” concrete foundation blocks at the northeast corner of the house (see enclosed sketch). This report includes; 1. 2. 3. 4. 5. Soil boring logs Percolation test results Testhole location and septic system configuration sketch Septic system design specifications Discussion and recommendations. The soil boring logs show that sandy loam surface soils overlie sandy clay loam to sandy clay subsurface soil horizons. Soil mottling begins at 2.0 to 3.0 feet depth at the boreholes. Soil mottles (spots of contrasting color) are accepted indicators of periodic saturation in soils. Ground water was encountered at Borehole #4 at six feet depth on September 22, 1987. Hole Elevation Depth (inches) Soil Texture at Bottom of Hole Percolation Rate (min/in)_ _ _ P-1 P-2 96.2 96.0 12 24 Sandy loam Sandy clay loam 9 22 The measured percolation rates are consistent with the texture of the soil materails in which the percolation tests were run. 222 Mor.i Stf; Anoka.

PL Mr. James Brownlee September 23, 1987 Page Two The City of Orono requires at least three feet elevation difference between to bottom of the filter rock of a septic system and ground water or indication of periodic soil saturation such as soil mottling. In order to maintain the required separation, a mound system is the recommended replacement septic system for this site. The mound is designed to serve a four bedroom house. Design sewage flow is 600 gallons per day. With a design infiltration rate of 1.2 gallons effluent per square foot per day for the medium sand fill material of the mound, the required rock bed area of the mound is 500 square feet. 600 gal/day t 1.2 gal/ft^/day = 500 ft' A rock bed 10.0 feet wide by 50.0 feet long provides the needed area. A minimum of one foot (1.0*) of medium sand should be con structed below the rock bed. The pressure distribution system of the mound consists of Schedule 40 PVC plastic pipe. The supply pipe should slope back towards the pumping chamber so that it drains after the mound is dosed. The laterals are 1.5 inch inside diameter pipes. The laterals should have 1/4 inch diameter holes drilled at a spacing of 3.0 feet. The laterals should be assembled to the manifold so that the holes point downwards into the rock bed. The distal ends of the laterals should be drilled horizontally in the end cap near the crown of the pipe to facilitate air venting. A submersible effluent pump capable of delivering at least 37.5 gallons per minute against a total dynamic head of at least 13.6 feet should be selected. Headlosses are calculated as follows: 1. Vertical headless of 7.7 feet between pump discharge (approx, elev. 90.0) and manifold (approx, elev. 97.7) 2. Friction loss of 0.7 feet in 30 feet of supply pipe (2.3 feet per 100 feet 2.0 inch inch I.D. plastic pipe at 37.5 gpro flow). 3. Friction loss of 0.2 feet in pipe fittings equal to 25 percent of friction loss in supply pipe. 4. Five feet (5.0*) to account for losses in distribution network. If as-built elevations are differnet from those above, headless should be recalculated to ensure proper pump selection. Mr. James Browniee September 23, 1987 Page Three The pump should be rigged with mercury float switches to dose about 150 gallons of effluent to the mound. An additional mercury float switch should be installed on a separate circuit to an alarm device to warn of pump failure. The mercury switches should be rigged to allow 600 gallons reserve capacity in the pumping chamber. All electrical connections should be watertight. The existing septic tank(s) should be checked for soundness (intact baffles; watertight) and capacity (1000 gallons each). If necessary the tank(s) should be repaired or replaced. The City of Orono re<iuir<:« two septic tanks hooked in series. The pumping chamber sh i ' have at least 1250 gallons capacity. It is recommended that a water meter be installed to monitor water use. The meter should be hooked to the water system such that exterior sillcocks are excluded. The water meter should be read periodically to ensure that the design capacity of the septic system is not exceeded. It is highly recommended that the installer of this septic system holds an Individual Sewage Treatment Systems Certificate for installation issued by the Minnesota Pollution Control Agency. The sole purpose of soils data contained herein is evaluation of soil suitability for on-site absorption of septic tank effluent at the test site.
