This warranty gives you specific legal rights and you may also have other rights which vary from state to state. PREINSTALLATION INFORMATION 1. Inspect your pump. Occasionally, products are damaged during shipment. If the unit is damaged, contact your distributor before using. DO NOT remove the test plugs in the cover nor the motor housing. 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. National Electrical Code (NEC) articles 500 through 503 explain in detail the requirements for the installation and wiring of electrical equipment in hazardous locations. SEE BELOW FOR LIST OF WARNINGS 1. Not for use in acidic, methanol or ethyl acetate atmospheres. 2. Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical cables can cause shock, burns or death. 3. Make sure there is a properly grounded connection available. All pumps are furnished with provisions for proper grounding to help protect you against the possibility of electrical shock. 4. Make certain that the control box is within the reach of the pump’s power supply cord. DO NOT USE AN EXTENSION CORD. Extension cords that are too long or too light do not deliver sufficient voltage to the pump motor. But, more important, they could present a safety hazard if the insulation were to become damaged or the connection end were to fall into the sump. 5. Make sure the pump electrical supply circuit is equipped with fuses and disconnect or circuit breakers of proper capacity. A separate branch circuit is recommended, sized according to the “National Electrical Code” for the current shown on the pump nameplate. 6. Risk of electric shock - These pumps have not been investigated for use in swimming pool areas. 7. According to the state of California (Prop 65), this product contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. 8. Electrical wiring and protection must be in accordance with the National Electrical Code per NEC articles 500 through 503 for installation in Class I, Division 1, Group C & D environments, and any other applicable state and local electrical requirements. 9. Use pressure-rated pipe and fittings when connecting to the disharge of the pump. CAUTION SEE BELOW FOR LIST OF CAUTIONS 1. Check to be sure your power source is capable of handling the voltage requirements of the motor, as indicated on the pump nameplate. 2. The float switches must be connected to an intrinsically safe circuit in the control panel. The installation of 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 pump apparatus or pit peculiarities and is secured so that the pump will shut off. It is recommended that rigid piping and fittings be used and the pit be 36" or larger in diameter. 3. INFORMATION - VENT HOLE PURPOSE. It is necessary that all submersible pumps capable of handling various sizes 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 in the discharge pipe below the check valve and pit cover to purge the unit of trapped air. Water stream will be visible from this hole during pump run periods. This vent hole should be checked periodically for clogging and cleaned as necessary. Trapped air is caused by agitation and/or a dry basin. 4. Water hammer creates momentary high pressure surges. These surges can cause severe damage to check valves and the piping system. Consideration for water hammer must be included in the piping system design. Reference ASPE Data Book, Chapter 2.33. Some systems may require external spring or lever weighted check valves or other engineered solutions. 5. Three phase pumps must be connected for proper rotation, which is counterclockwise looking into impeller inlet. 6. Care should be taken during the initial installation to be sure that adequate air supply is available whenever any person is in the basin. Always follow OSHA guidelines on confined space requirements. © Copyright 2014 Zoeller® Co.

Moisture sensor indicator panel, 10-1031, is recommended but not required for automatic pump models. 4. Three phase pumps require overload protection in the control panel. 5. These pumps are to be repaired by firms approved by Zoeller Company and in accordance to Policy # FM0212-3d. Otherwise, they are to be returned to the factory for repair. FIELD ASSEMBLED INSTALLATION 1. Contractor shall furnish all labor, material, equipment and incidentals required for installation of hazardous environmental pump. 2. Installation and piping instructions are included with the rail system and basin instructions. If pump is being retrofitted to an existing rail system, accessory parts may be required. Consult the factory and advise make and model of rail system being used. 3. All electrical connections including pump to control box and power supply to control panels must comply with the “National Electrical Code” and applicable local codes. Installation of electrical panels and connections should be made by a qualified licensed electrician. 4. When installing a pump with a check valve, or a rail system with a check valve, you must give the pump case time to fill to help prevent air lock when lowering the unit into the liquid. The 6404/6405 pump case has an air vent located behind the discharge. This air vent is across the pump housing mounting surface and must be cleaned before each reinstall. An air vent hole (3/16") must be drilled in discharge pipe below the check valve to help prevent air lock. This drilled hole must be cleaned before each reinstall. After the pump is installed, run the unit submerged to assure the pump case is filled (Water should come out of 3/16" diameter hole). 010740 © Copyright 2014 Zoeller® Co.

All rights reserved. 9 INSTRUCTIONS FOR CHECKING ROTATION OF THREE PHASE UNITS It is very important that these units be connected for proper rotation. Since no rotating parts are visible without removing the pump from the pit, the rotation on 3 phase units should be checked before installation into the pit as follows: After the proper electrical connections are made, momentarily energize the pump observing the direction of kick back due to starting torque. The rotation is correct if the kick back is in the opposite direction of the rotation arrow. If the rotation is not correct, disconnect power and switch any two power leads. Turn power back on and retest for proper rotation. SENSOR WIRES (See pages 8 and 9) The power and sensor wires are contained in the same cord. The green wire is a ground connection. All wires must terminate in the control panel. The following should be noted: (1) The thermal sensors are normally closed and mounted adjacent to the motor windings. If internal temperatures exceed a maximum limit, the pump will deactivate. On 3 phase models connect the white and red wires with the black tracer to the control panel's thermal cut-out terminals. The pump is able to restart once the motor cools down. Continued deactivation of this circuit requires the attention from maintenance personnel. (2) The seal failure wires are connected to a 330K ohm moisture detection circuit. An indicator light will activate whenever water is present in the shaft seal cavity or cord cap assembly. Whenever the seal leak light is activated, indicating the entry of moisture into the pump, it should be removed and serviced in order to avoid damage to the motor. Moisture sensor circuit can be checked for continuity (complete circuit) with a (Volt-OHM-Meter). Set the VOM to read resistance and connect the VOM leads to the moisture sensor wires. The VOM should read approximately 330k Ohms. Resistance readings significantly lower indicates an entry of moisture into the pump. If VOM reading is open then a problem exists with moisture detection circuit. (3) The green wire shall be connected to a ground lug in the panel. Check resistance between the green ground conductor and all other wires. This resistance reading should indicate an open circuit. If VOM reading returns a reading other than open, then a problem exists with the sensor circuit wiring or cordage and the pump should be taken to an approved repair station. CONTROL PANELS These pumps are nonautomatic and they require a control panel with intrinsically safe float and moisture sensor circuits. A motor starter circuit, control circuit, and high-water alarm circuit within the panel are standard features. Enclosures rated for outdoor use and alternating relays are often required. The following should be noted. (1) The seal failure sensor and thermal sensor (3 phase only) protection require that interfacing terminals and functions be incorporated into the panel. (2) All 3 phase pumps require overload protection in panel. Use with approved motor control that matches motor input in full load amperes with overload element(s) selected or adjusted in accordance with control instructions. (3) Lightning arrestors, condensation heaters and elapsed-time meters are optional features that provide added protection. GENERAL MAINTENANCE Repair and service must be performed by a firm approved by Zoeller Company to repair a pump with an explosion-proof motor in accordance to the guidelines listed in Policy # FM0212-3d. Contact the Zoeller Product Support Department for additional information. If the motor housing or cord cap is disassembled or repaired by a firm NOT approved to work on explosion-proof motors, the explosion proof rating is void, and the FM and CSA tags MUST BE REMOVED FROM THE PUMP. SAFETY PROCEDURES For your protection, always disconnect pump and panel from its power source before handling. Never enter the basin until it has been properly vented and tested. Any person entering a basin should be wearing a harness with safety rope extending to the surface so that they can be pulled out in case of asphyxiation. Sewage water gives off methane and hydrogen sulfide gases, both of which can be highly poisonous. Installation and checking of electrical circuits and hardware should be performed by a qualified electrician. Pump is never to be lifted by power cord. Unit must be cleaned and disinfected, inside the pumping chamber and all exterior surfaces, prior to servicing. GENERAL SYSTEM INSPECTION Before the system is placed into operation, it should be inspected by a qualified technician. Wiring and grounding must be in accordance with the National Electrical Code and all applicable local codes and ordinances. LUBRICATION PROCEDURES No lubrication is required. If pumps are to be stored for more than six months, refer to short term storage procedure in the Operation section. PREVENTIVE MAINTENANCE Preventive maintenance is recommended to ensure a long service life from the product. Provided is a suggested maintenance schedule. Every six months: • Inspect and test system for proper operation. • Check for proper and unobstructed float operation. • Listen for proper check valve operation. Every 5 years or 10,000 hours of operation: • Remove pump, inspect and service using a Zoeller rebuild kit. • Flush and clean basin. © Copyright 2014 Zoeller® Co. All rights reserved. 10 OPERATION GENERAL Zoeller pumps are lubricated and tested at the factory prior to shipment and require minimum pre-start-up maintenance. Maximum operating temperature of pump liquid must not exceed 104°F (40°C). These units are not designed to handle liquids other than effluent: 160 and 180 or sanitary sewage: 280, 290 and 400. If pump is used to dewater areas with contaminated liquids with heavy or abrasive materials, the warranty will be voided. NAMEPLATE DATA The nameplate, located on the side of the pump, indicates specific information about the construction of the pump. The model number and date code information should be recorded on the front page in the “Owner’s Information” section of this manual. SHORT TERM STORAGE When not in use, the pump should be stored and the following is advised: • • • • Store pump inside whenever possible or cover with some type of protective covering. Tape or seal in plastic bag the terminal ends of wire leads. Spray coat unpainted surfaces with rust inhibiting oil. The impeller should be rotated every six months in order to keep the seals lubricated and not develop a permanent set. If panel is to be stored, the following is advised: • • • • Store the panel inside whenever possible and leave in the shipping box. All openings shall be sealed. Store in an upright position. Do not stack anything on top of panel. START-UP PROCEDURE ADJUSTMENT PROCEDURE Pumps: No adjustments are required. Floats: Nonautomatic - Refer to the system drawing or to the panel wiring schematic for the desired location of each float switch setting. Automatic - Float is factory set to provide approximate on/off levels as follows: SERIES X160/X190 X280 X290 OFF 9-3/4" 10" 9-3/4" A tighter pumping range can be set by moving the float stop closer to the float thereby lowering the "on" point. Valves: Discharge valves should be placed in the fully open position. Systems should not be operated for extended periods of time with the discharge valves partially closed due to damaging the valve. SHUTDOWN PROCEDURES If a system is shutdown for more than six months, the following is recommended: Pumps: If pit is to remain dry, then the pump can remain in the pit. With the pump in the pit, it should be operated for five minutes once every three months. If the pit is to remain wet, the pump should be removed and stored as noted above. Panels: The panel should have all openings sealed to prevent moisture and dust from entering the enclosure. Prior to restarting system, the panel should be inspected for presence of moisture and any loose connections. Valves: Consult the valve/actuator supplier for information concerning these systems components. Before placing the equipment into operation the following should be checked: • • • • • ON 19-1/2" 19-3/4" 19-1/2" Clean pit. Electrical boxes dry and securely installed. Floats positioned properly. Discharge valves open. 3/16” vent hole drilled in pipe between check valve and pump. Once the above has been verified proceed with the following checks: • Pump power cables and control floats properly installed and voltage verified. • Conduit connections to panel are properly sealed. • After installing the pump into the containment area, with adequate submergence, open the discharge valve fully. Start the unit using manual controls. If flow is appreciably less than rated performance, pump may be air locked. To expel trapped air, jog the unit several times, using the manual controls. • Have a qualified electrician take voltage and current measurements with the pump running. Record these readings in the space provided in the “Owner’s Information” section on page 1 of this manual for future reference. © Copyright 2014 Zoeller® Co.

Make sure you are wearing insulated protective sole shoes and not standing in water. Under flooded conditions, contact your local electric company or a qualified licensed electrician for disconnecting electrical service to the pump prior to removal. Pumps contain oil which becomes pressurized and hot under operating conditions. Allow 2-1/2 hours after shut down before servicing pump. Condition Common Causes A. Pump will not start or run. Blown panel or circuit breaker fuse, low voltage, thermal overload open, impeller clogged, float switch held down or defective, incorrect wiring in control panel, water in cap assembly. B. Motor overheats and trips on overload. Incorrect voltage, impeller blocked, negative head (discharge lower than intake of pump). Pump runs continuously at low water level. Low oil level in motor shell. C. Pump will not shut off. Air lock, debris under float assembly, incoming sewage exceeds capacity of pump. D. Pump operates but delivers little or no water. Intake clogged with grease or sludge, pump air locked (clear vent hole), low or incorrect voltage, clogged discharge line, operating near shut-off head. E. Pump starts and stops too often. Check valve stuck open. Sump pit too small to handle incoming sewage. Level control out of adjustment. Thermal overload tripping. F. Large red flashing light comes on at control box. High water in pit. Check pump for clogging, or overload trip. See “A” and “D” above. G. Grease and solids accumulate in pit around pump. Break up solids and run pump with water running into the pit. Allow level to lower to the pump intake. Continue until solids are cleared from the pit. Do not drain kitchen grease down the sink. ® MAIL TO: P.O.
