To avoid burns, allow it to cool for 30 minutes after shutdown before handling it. m Submersible sump pumps are not approved for use in swimming pools, recreational water installations, decorative fountains or any installation where human contact with the pumped fluid is common. Pump designed to be installed in a sump or wet location where drainage collects. m DANGER: Risk of Electrical Shock or Electrocution. May result in serious injury or death or fire hazard. Installer must disconnect all electrical sources prior to installation, handling or servicing. Only qualified personnel may install this system. NFPA 70/National Electric Code (NEC) or local codes must be followed. System must be properly grounded according to NEC. Do not lift pump by power cord. DO NOT THROW AWAY OR LOSE THIS MANUAL. Keep it in a safe place so that you may refer to it often for the continued safe operation of the product. PUMP MODELS: These instructions cover the installation and service of the 3WHV/V3WHV/3WHR and 4WHV/V4WHV/4WHR series of solids handling pumps and guide rail systems for the horizontal discharge models only. These models are designed for handling raw sewage and wastewater. Do not use for acid wastewater. The pumps have vortex, solids handling impellers. These pumps will pass 3" dia. solids and has a 3" or 4" std. flange discharge. m DANGER: Biohazard Risk. Once wastewater source has been connected to system, Biohazard Risk exists. Installer(s) and/or service personnel must use proper Personal Protective Equipment and follow handling procedures per OSHA 29 CFR 1910.1030 when handling equipment after wastewater source has been connected to system. m DANGER: Risk of Asphyxiation. Installer(s) and/or service personnel must use proper Personal Protective Equipment and follow OSHA 29 CFR 1910.146 or OSHA 29 CFR 1926. Pump may be installed in a location classified by as a confined space. SEAL FAILURE (4WHV/ V4WHV/ 4WHR ONLY): These pumps have a probe installed in the seal chamber, so that any leakage past the lower seal is detected. A red warning light at the control panel comes on if water enters the seal chamber. This is an indicator only and does not stop the motor. It warns that the seal should be replaced immediately. LONGER RUNNING WITHOUT SEAL REPLACEMENT COULD DAMAGE MOTOR. MOTOR MUST GO TO AUTHORIZED SERVICE STATION FOR SEAL REPLACEMENT. m DANGER: Risk of Fire or Explosion. Do not smoke or use open flames in or around this system. This system is intended for use in hazardous locations per NFPA 70 National Electric Code. Do not pump flammable liquids. m DANGER: Cutting Risk. Risk of serious cutting or amputation exists. Disconnect all power sources prior to servicing pump. Pump may start without warning. HEAT SENSOR (4WHV/ V4WHV/ 4WHR ONLY): All single and three phase pumps have motor heat sensors that are externally wired to the control panel. Any motor temperature above the sensor rating will open the heat sensor and stop the motor. The sensor will automatically close upon cooling. It is important that the heat sensor wires and seal failure wires are connected at the panel terminal block. Warranty is void if wires are not connected or are jumped. m DO NOT modify the cord and plug. When using the cord and plug, plug into a grounded outlet only. When wiring to a system control, connect the pump ground lead to the system ground. CAUTION: The single phase pumps with automatic heat sensor reset will restart without warning as the motor cools. Therefore, never do service work on the pump unless power supply is disconnected. 23833A661 11/21/13 2 ELECTRICAL CONTROLS (All Models) WARNING: On three phase pumps only qualified persons shall conduct services and installation of this pump. The pump must be wired by a qualified electrician, using an approved starter box and switching device. FLOAT SWITCH INSTALLATION 1. Level Controls are held by support bracket and cords are adjusted for proper depth. a. Lower Turn-Off Control should be set so that pump stops when water level is about at the top of the volute. b. First Turn-On Control is set to start pump when level is at height specified above pump. c. Second Turn-On Control of a duplex pump system is set at height specified above first turnon control. d. Alarm Control is set about 6" to 12" above the highest Turn-On Control. e. No control should be set above basin inlet invert. CAUTION: Never pull pump or work on control box until incoming power is disconnected. Never run motor until green ground conductor is connected to a good outside ground. Never pull electrical cable to lift pump. If the control panel is not located near the pump, consult wire gauge table for permissible wire gauge to run between the control panel and the junction box at the wet well. CALIFORNIA PROPOSITION 65 WARNING: This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. MAKING ELECTRICAL CONNECTIONS 1. If control panel is mounted directly on basin top, the power and control wires are taken directly to control box and are sealed in the cord pallet with cord grip connectors. 2. If panel is installed remote from basin, the cords can be taken through a conduit to control panel, or junction box can be used in the basin to make connections. The Myers junction box has a built-in sealing connector to seal the outgoing wires. If other than Myers junction box is used, a separate sealing connector must be used where wires leave the basin. OIL FILLED MOTOR: The motor chamber and seal chamber are dielectric oil-filled for good heat transfer and lubrication of bearings and seals. The motor requires no other lubrication. Oil level in the motor housing should be to the bottom of the oil fill plug with the pump in a vertical position. Do not overfill the motor housing since some space is required for oil expansion. Oil level in the seal chamber should be checked with the pump lying horizontally with the fill plug at the top. The oil level should be approximately 3/4" from the outside surface of the housing. Transformer oil should be used and may be purchased from your Myers® dealer. CAUTION: If cords are taken directly through a conduit to control box, a seal fitting must be used at inlet of conduit to prevent gas vapors from getting to control box. This type of installation is generally not recommended because the sealing cement must be broken to remove a cord. AIR VENTING: Upon initial filling of the wet well with the water, air may be trapped in the pump volute. To vent off this air, a 5/32" diameter hole is located in the volute. BE SURE THIS VENT HOLE IS CLEAN AFTER ANY SERVICE WORK ON PUMP. MOTOR ELECTRICAL CONNECTIONS Single phase motors are for 230 volts only. A special control panel with start and run capacitors and start relay are required for these pumps. These control panels must be obtained from Myers (or must be approved by Myers) or warranty on motor is void. Also, warranty is void if the heat sensor and seal fixture wires are not connected properly to control box terminal strip. CAUTION: Pump motor is not to be taken apart in the field. Motors under warranty must be serviced by Myers authorized repair station or be sent to factory. 3 23833A661 11/21/13 3WHV / V3WHV / 3WHR IMPELLER AND VOLUTE PART NUMBERS Pump 3WHV/V3WHV10M4-21 3WHV/V3WHV10M4-03 3WHV/V3WHV10M4-23 3WHV/V3WHV10M4-43 3WHV/V3WHV10M4-53 3WHV/V3WHV15M4-21 3WHV/V3WHV15M4-03 3WHV/V3WHV15M4-23 3WHV/V3WHV15M4-43 3WHV/V3WHV15M4-53 3WHV/V3WHV20M4-21 3WHV/V3WHV20M4-03 3WHV/V3WHV20M4-23 3WHV/V3WHV20M4-43 3WHV/V3WHV20M4-53 3WHV/V3WHV20M4-43 3WHV/V3WHV30M4-21 3WHV/V3WHV30M4-03 3WHV/V3WHV30M4-23 3WHV/V3WHV30M4-43 3WHV/V3WHV30M4-53 3WHV/V3WHV50M4-21 3WHV/V3WHV50M4-03 3WHV/V3WHV50M4-23 3WHV/V3WHV50M4-43 3WHV/V3WHV50M4-53 3WHR15M4-01 3WHR15M4-21 3WHR15M4-03 3WHR15M4-23 3WHR15M4-43 3WHR15M4-53 3WHR20M4-01 3WHR20M4-21 3WHR20M4-03 3WHR20M4-23 3WHR20M4-43 3WHR20M4-53 3WHR30M4-21 3WHR30M4-03 3WHR30M4-23 3WHR30M4-43 3WHR30M4-53 3WHR50M4-21 3WHR50M4-03 3WHR50M4-23 3WHR50M4-43 3WHR50M4-53 RPM 1750 1750 1750 1750 1750 1750 1750 hp 1 1.5 2 3 5 1.5 2 Trim Impeller 5 Pump Catalog No. 3WHV10M4-21 V3WHV10M4-21 3WHV10M4-03 V3WHV10M4-03 3WHV10M4-23 V3WHV10M4-23 3WHV10M4-43 V3WHV10M4-43 3WHV10M4-53 V3WHV10M4-53 3WHV15M4-21 V3WHV15M4-21 3WHV15M4-03 V3WHV15M4-03 3WHV15M4-23 V3WHV15M4-23 3WHV15M4-43 V3WHV15M4-43 3WHV15M4-53 V3WHV15M4-53 3WHV20M4-21 V3WHV20M4-21 3WHV20M4-01 V3WHV20M4-01 3WHV20M4-03 V3WHV20M4-03 3WHV20M4-23 V3WHV20M4-23 3WHV20M4-43 V3WHV20M4-43 3WHV20M4-53 V3WHV20M4-53 3WHV30M4-21 V3WHV30M4-21 3WHV30M4-03 V3WHV30M4-03 3WHV30M4-23 V3WHV30M4-23 3WHV30M4-43 V3WHV30M4-43 3WHV30M4-53 V3WHV30M4-53 3WHV50M4-21 V3WHV50M4-21 3WHV50M4-03 V3WHV50M4-03 3WHV50M4-23 V3WHV50M4-23 3WHV50M4-43 V3WHV50M4-43 3WHV50M4-53 V3WHV50M4-53 24415E030 5.5 22946C511 6 22946C507 6.5 3WHV – 22945D000 V3WHV – 22945E100 22946C503 6.75 5 Volute 22946C501 0708120002 5.25 070812022 27706D000 1750 1750 3 5 6 6.75 070812012 070812032 Shaft w/Rotor Stator Only Housing w/Stator 24416C000 24407C211 24406D120K 24416C001 24407C212 24406D125K 24416C001 24407C213 24406D130K 24416C001 24407C213 24406D135K 24416C001 24407C214 24406D140K 24416C000 24407C211 24406D120K 24416C001 24407C212 24406D125K 24416C001 24407C213 24406D130K 24416C001 24407C213 24406D135K 24416C001 24407C214 24406D140K 24416C002 24407C215 24406D145K 24416C002 24407C239 24406D195K 24416C003 24407C216 24406D150K 24416C003 24407C217 24406D155K 24416C003 24407C217 24406D160K 24416C003 24407C218 24406D165K 24416C004 24407C219 24406D170K 24416C004 24407C220 24406D175K 24416C004 24407C221 24406D180K 24416C004 24407C221 24406D185K 24416C004 24407C222 24406D190K 24416C004 24407C204 24406D170K 24416C004 24407C220 24406D175K 24416C004 24407C221 24406D180K 24416C004 24407C221 24406D185K 24416C004 24407C222 24406D190K REGAL MOTOR END PARTS LIST Ref. 1 2 3 4 5 6 7 8 9 10 11 Description 35' CORD ASSEMBLY 14-4 35' CORD ASSEMBLY 10-4 35' CORD ASSEMBLY 8-4 SOOW 35' CORD ASSEMBLY 8-4 W SCREW; MACH ST 10-24UNC x 3/8 LG WASHER; LOCK SHKPRF INTERNAL ST NO 10 PLATE; SEALING, UPPER WGL SERIES SCREW; CAP HEX ST SPEC #10-24UNC x 7/8 LG GROMMET; SEALING POWER WHV SERIES PLATE; SEALING LOWER WGL SERIES ST WIRE; ELECT 10 GA 1 STR RED 12 LG WIRE; ELECT 10 GA 1 STR WHITE 12 LG WIRE; ELECT 10 GA 1 STR BLACK 12 LG WASHER; SPRING FINGER 1.189 ID x 1.830 OD 23833A661 11/21/13 Qty.

Remove bolts between seal housing flange and volute case. The motor and impeller can now be lifted off as a unit. 2. If necessary to remove impeller, lay pump on its side. With a screwdriver bend the tabs of the lockwasher away from the hex head bolt. 3. Loosen and remove the bolt by turning counterclockwise. Since Loctite® is used to secure the bolt and is applied to the shaft/impeller interface, heating of the shaft end to 450º F will usually be required. 4. Impeller is mounted by a straight fit with driving key. Pry evenly on opposite impeller sides with two large screwdrivers or small bars behind the impeller. 5. Set motor on end with shaft up after removing impeller so that oil will not drain past the seal. REPLACING IMPELLER AND PUMP CASE 1. Apply Loctite #680; before assembly, in keyway, in the impeller bore (lower shaft O.D.), and on the threads of the hex head cap screw. 2. Before placing the impeller on the shaft, be sure the mechanical seal and its spring are in place. 3. Position retaining washer with long pin extension in keyway. 4. Assemble hex head cap screw and tighten securely. CAP SCREW TORQUE VALUE 3/8-16 1/2-13 5/8-11 20 ft.-lbs. 43 ft.-lbs. 93 ft-lbs. 3/4-10 128 ft.-lbs. TROUBLE CHECK LIST Troubles listed generally pertain to the pump and auxiliary components. Other trouble can occur from a faulty control box. These will be listed with the control box instructions. CONDITION PROBABLE CAUSE Pump runs but does not pump liquid from basin. 1. 2. 3. 4. 5. 6. 7. 8. Pump impeller may be air locked; this occasionally occurs on a new installation. Start and stop pump several times to purge air. Be sure air vent hold in volute case is clean. Run additional water into basin so that pump will be submerged deeper to clear air. If pump is three phase, rotation may be wrong. See instructions for checking proper rotation. If pump has been installed for some time and does not pump, it may be clogged at inlet. Discharge gate valve may be closed. Discharge check valve may be clogged or have a broken clapper or spring. Discharge head may be too high. Check elevation. If above checks do not locate trouble, motor rotor may be loose on shaft which allows motor to run but will not turn impeller or only at low RPM. Red light comes on at control box. 1. This indicates some water has leaked past the lower seal and has entered the seal chamber and made contact with the electrode probe. Pump must be removed immediately from basin for replacement of lower seal. This preventive repair will save an expensive motor. 23833A661 11/21/13 10 TROUBLE CHECK LIST (Cont’d) CONDITION PROBABLE CAUSE 1. Overload trips at control box and alarm buzzer or flashing red light comes on due to high water level in basin. 2. 3. Push red reset button to reset overload. If overload trips again after short run, pump has some damage and must be removed from basin for checking. Trouble may be from clogged impeller causing motor to overload or could be from failed motor. Trouble may be from faulty component in control box. Always check control box before removing pump. Yellow run light stays on continuously. 1. 2. 3. 4. 5. Indicates H-O-A switch may be in the Hand position. Level control switch may have failed causing pump to continue to operate when water is below lower control. Impeller may be partially clogged causing pump to operate at much reduced capacity. Gate valve or check valve may be clogged causing low pump flow. Pump may be air logged. Lift arm on check valve to vent off air. Also, check that the 5/32" vent hole in volute is open. Circuit breaker trips. 1. 2. 3. Reset breaker by pushing clear down on handle then back to On position. If breaker trips again in few seconds, it indicates excessive load probably caused by a short in the motor or control box. Check out instructions given with control box before pulling pump. If this condition happens after an electrical storm, motor or control box may be damaged by lightning. Resistance reading of the motor with lead wires disconnected from the control box can determine if trouble is in motor or control box. Pump is noisy and pump rate is low. 1. 2. 3. Impeller may be partially clogged with some foreign objects causing noise and overload on the motor. Impeller may be rubbing on wear ring due to bent shaft or misalignment. Pump may be operating too close to shut-off. Check head. Grease and solids have accumulated around pump and will not pump out of basin. 1. 2. 3. Lower control which may be set too high. Run pump on manual operation for several minutes with small amount of water running into basin to clean out solids and grease. This allows pump to break suction and surge, breaking up the solids. If level switch is set properly, this condition generally will not occur. Trash and grease may have accumulated around floats causing pump to operate erratically. 11 23833A661 11/21/13 STANDARD LIMITED WARRANTY Myers® warrants its products against defects in material and workmanship for a period of 12 months from the date of shipment from Myers or 18 months from the manufacturing date, whichever occurs first - provided that such products are used in compliance with the requirements of the Myers catalog and technical manuals for use in pumping raw sewage, municipal wastewater or similar, abrasive free non-corrosive liquids.
