Never install the pump in a trench, ditch, or hole with a dirt bottom; the legs will sink into the dirt and the suction will become plugged. SECTION B: GENERAL INFORMATION B-1) To The Purchaser: Congratulations! You are the owner of one of the finest pumps on the market today. Barnes® Pumps are products engineered and manufactured of high quality components. Over one hundred years of pump building experience along with a continuing quality assurance program combine to produce a pump which will stand up to the toughest applications. C-1.1) Submergence: The pump should always be operated in the submerged condition. The minimum sump liquid level should never be less than A Dimension, A = 6.50 inches on SEV Series and A=4.50 inches on EHV Series above the pump bottom. The recommended level should not drop below the top of the motor housing (see Fig. 1). Check local codes and requirements before installation. Servicing should be performed by knowledgeable pump service contractors or authorized service stations. The pump is packaged ready for installation and no connections or adjustments are necessary except for attaching discharge piping and plugging in service cord. B-2) Receiving: Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file a claim immediately with the company that delivered the pump. If the manual is removed from the crating, do not lose or misplace. B-3) Storage: Short Term- Barnes Pumps are manufactured for efficient performance following long inoperative periods in storage. For best results, pumps can be retained in storage, as factory assembled, in a dry atmosphere with constant temperatures for up to six (6) months. Long Term- Any length of time exceeding six (6) months, but not more than twenty four (24) months. The units should be stored in a temperature controlled area, a roofed over walled enclosure that provides protection from the elements (rain, snow, wind blown dust, etc..), and whose temperature can be maintained between +40 deg. F and +120 deg. F. Pump should be stored in its original shipping container and before initial start up, rotate impeller by hand to assure seal and impeller rotate freely. FIGURE 1 C-2) Discharge: Discharge piping should be as short as possible. Both a check valve and a shut-off valve are recommended for each pump being used. The check valve is used to prevent backflow into the sump. Excessive backflow can cause flooding and/or damage to the pump. The shut-off valve is used to stop system flow during pump or check valve servicing. B-4) Service Centers: For the location of the nearest Barnes Service Center, check your Barnes representative or Crane Pumps & Systems, Inc., Service Department in Piqua, Ohio, telephone (937) 778-8947 or Crane Pumps & Systems Canada, Inc., Bramton, Ontario, (905) 457-6223. C-3) Liquid Level Controls Figure 2 shows a typical installation for any submersible pump using a level control mounted to the discharge piping with a piggy-back plug. SECTION C: INSTALLATION General Comments: 1) Never work in the sump with the power on. C-1) Location: These pumping units are self-contained and are recommended for use in a sump or basin. The sump or basin shall be vented in accordance with local plumbing codes. This pump is designed to pump effluent or wastewater, nonexplosive and noncorrosive liquids and shall NOT be installed in locations classified as hazardous in accordance with the National Electrical Code (NEC), 2) Level controls are factory set for a pumping differential of 9 inches. If that is the cycle desired, simply circle the discharge pipe with the pipe mounting strap, feed the end through the worm drive, and tighten with a screwdriver. Be certain that the level control cannot hang up or foul in its swing. Also, make certain the pump impeller is still submerged when the level control is in the “OFF” mode. 5 6.) Figure 3 shows a typical connection for pumps with the wide angle float and piggy-back plug, for manual and automatic operations. Automatic Manual FIGURE 3 Automatic - Plug float cord into GFI outlet, then plug pump cord into float cord. Manual - Plug pump cord directly into GFI outlet. FIGURE 2 3) 4) 5) If a higher pump differential is needed, grip the cord near the neck of the float, then using the other hand, exert a steady force on the lower edge of the cable clamp. The cable clamp should slide up to the new pivot point. Attach the level control to the discharge hose in the manner described above. C-4) Electrical Connections: C-4.1) Power Cable: The cord assembly mounted to the pump must not be modified in any way except for shortening to a specific application. Any splice between the pump and the control panel must be made in accordance with local electric codes. It is recommended that a junction box, if used, be mounted outside the sump or be of at least NEMA 4 (EEMAC-4) construction if located within the wet well. Do not use the power cable to lift pump. Plug the level control plug into the GFI receptacle, then plug the pump into the piggyback plug. One cycle of operation should be observed , so that any potential problems can be corrected. It is recommended that the float should be set to insure that the sump well liquid level never drops below the top of the motor housing or a minimum level of 4.50 inches on EHV Series and 6.50 inches on SEV Series above the pump bottom.

Pump rated for operation at ± 10% voltage at motor. 6 C-4.2) Overload Protection: Single Phase - The type of in-winding overload protector used is referred to as an inherent overheating protector and operates on the combined effect of temperature and current. This means that the overload protector will trip out and shut the pump off if the windings become too hot, or the load current passing through them becomes too high. It will then automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload, the source of this condition should be determined and rectified immediately. DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS ! D-1.1) Checking Oil: To check oil, set unit upright. Remove pipe plug. With a flashlight, visually inspect the oil in the motor housing to make sure it is clean, clear and that the oil level is above all internal componentry. If oil appears satisfactory, replace pipe plug. If oil is low or appears contaminated, test oil as per section D-1.2 D-1.2) Testing Oil: 1. Place pump on its side, remove pipe plug and drain oil into clean, dry container. 2. Check oil for contamination using an oil tester with a range to 30 kilovolts breakdown. If current through the temperature sensor exceeds the values listed, an intermediate control circuit relay must be used to reduce the current or the sensor will not work properly. 3. If oil is found to be clean and uncontaminated (measures above 15 kilovolts breakdown), refill the motor housing with oil. 4. If oil is found to be dirty or contaminated (measures below 15 kilovolts breakdown), then the pump must be carefully inspected for leaks at the shaft seal (1), cord inlet (2) , square ring and pipe plug before refilling with oil. TEMPERATURE SENSOR ELECTRICAL RATINGS Volts Continuous Amperes Inrush Amperes 110-120 3.00 30.0 D-1.3 Replacing Oil in Motor Housing: Drain all oil from motor housing and dispose of properly. Refill with 32 ounces of new cooling oil as per Table 1. An air space must remain in the top of the motor housing to compensate for air expansion. Set unit upright and fill only until oil level from top of pipe plug boss is 3” ± 1/4”. C-4.3) Wire Size: Consult a qualified electrician for proper wire size. See table for electrical information. SECTION D: SERVICE AND REPAIR NOTE: All item numbers ( ) refer to Figure 8. WARNING ! - DO NOT overfill oil. Overfilling of motor housing with oil can create excessive and dangerous hydraulic pressure which can destroy the pump and create a hazard. Overfilling oil voids warranty. D-1) Lubrication: Anytime the pump is removed from operation and at least every twelve (12) months, the cooling oil in the motor housing must be checked visually for oil level and contamination.

E-1 SHAFT SEAL SERVICE: Disconnect power, remove screws and lockwashers, and vertically lift motor assembly from body. Clean out body if necessary. Clean and examine impeller for pitting or wear. The impeller is threaded onto the shaft and to remove, unscrew impeller, holding shaft with a large screwdriver. CAUTION: - Handle seal parts with extreme care. DO NOT scratch or mar lapped surfaces. It is extremely important to keep seal faces clean during assembly. Dirt particles lodged between these faces will cause the seal to leak. Place spring (1b) over shaft and in place on rotating member (1c), making sure it is seated. Slide retaining ring (1a) over shaft and let rest on spring (1b). To expose shaft seal (1) disassemble volute and impeller as outlined in above paragraph. Remove rotating member (1b) from shaft (See Fig. 4). Examine all seal parts and especially contact faces. Inspect seal for signs of wear such as uneven wear pattern on stationary members, chips and scratches on either seal face. DO NOT interchange seal components, replace the entire shaft seal (1). If replacing seal, remove stationary (1a) by prying out with flat screw driver. Before installing impeller, inspect threads on shaft and impeller to assure that they are clean. Apply a threadlocking compound to shaft threads and screw impeller onto shaft and tighten. Rotate impeller to check for binding. Install motor housing assembly on pump body. Apply thread locking compound to each cap screw, thread into body with lockwashers, and torque to 11 ft. lbs. Check for free rotation of impeller.
