symbol on your pump or in this manual, look for one of the following signal words and be alert to the potential for personal injury!

warns about hazards that will cause serious

personal injury, death or major property damage if ignored.

warns about hazards that can cause serious

personal injury, death or major property damage if ignored.

warns about hazards that will or can cause

minor personal injury or property damage if ignored. The word NOTICE indicates special instructions which are

important but not related to hazards. Electrically powered sump pumps normally give many years

of trouble-free service when correctly installed, maintained, and used. However, unusual circumstances (interruption of power to the pump, dirt/debris in the sump, flooding that exceeds the pump’s capacity, electrical or mechanical failure in the pump, etc.) may prevent your pump from functioning normally. To prevent possible water damage due to flooding, consult your dealer about installing a secondary sump pump, a DC backup sump pump, and/or a high water alarm. See the “Troubleshooting Chart” in this manual for information about common sump pump problems and remedies. For more information, see your dealer or call customer service at 1-888-782-7483.

1. Know the pump application, limitations, and potential hazards.

2. Disconnect power before servicing.

3. Release all pressure within system before servicing any component.

4. Drain all water from system before servicing.

5. Secure discharge line before starting pump. An unsecured discharge line will whip, possibly causing personal injury and/or property damage.

6. Check hoses for weak or worn condition before each use, making certain that all connections are secure.

7. Periodically inspect sump, pump and system components. Keep free of debris and foreign objects. Perform routine maintenance as required.

8. Provide means of pressure relief for pumps whose discharge line can be shut-off or obstructed.

9. Personal Safety: a. Wear safety glasses at all times when working with

pumps.

b. Keep work area clean, uncluttered and properly light-

ed – replace all unused tools and equipment. c. Keep visitors at a safe distance from work area. d. Make workshop child-proof – with padlocks, master

switches, and by removing starter keys.

PERFORMANCE

INSTALLATION

1. Install pump in sump pit with minimum diameter of 10" (254mm) for models equipped with vertical switches and 14" (356mm) for float switch models. Sump depth should be 14" (356mm). Construct sump pit of tile, concrete, steel or plastic. Check local codes for approved materials.

2. Install pump in pit so that switch operating mechanism has maximum possible clearance.

3. Pump should not be installed on clay, earth or sand surfaces. Clean sump pit of small stones and gravel which could clog pump. Keep pump inlet screen clear.

NOTICE: Do not use ordinary pipe joint compound on plastic pipe. Pipe joint compound can attack plastics.

4. Install discharge plumbing. When using rigid pipe, use plastic pipe.

A. For D125, D133, and D150 Series: Wrap thread

with Teflon tape

. Screw pipe into pump hand tight +1 – 1-1/2 turns. Thread outlet pipe into pump body carefully to avoid stripping or crossing threads.

B. D175 Series: Slip connector hose over pump dis-

charge. Install and tighten first clamp. Place second clamp loosely over connector hose. Slip connector hose over discharge pipe. Clamp hose tightly with second clamp.

NOTICE: Discharge piping should be as short as possible to reduce pipe friction losses. Discharge pipe diameter should be equal to or larger than discharge size of pump. Smaller pipe diameters will restrict capacity of pump and reduce performance. Do no use flexible discharge pipe in any permanent installation.

Risk of flooding. Failure to secure pump may allow pump movement, switch interference and prevent pump from starting or stopping.

If a flexible discharge hose is used, make sure pump is secured in sump to prevent movement.

5. To reduce motor noise and vibrations, a short length of rubber hose (e.g. radiator hose) can be connected into discharge line near pump using suitable clamps.

6. For D125, D133, and D150 Series ONLY: Install an inline check valve to prevent flow backwards through pump when pump shuts off.

NOTICE: Drill 1/8" (3.2 mm) hole in discharge pipe just above pump body but below check valve to prevent air locks. D175 Series pumps have an internal check valve and don’t require drilling.

7. Power Supply: Pump is designed for 115 V., 60 Hz., operation and requires a minimum 15 amp individual branch circuit. Both pump and switch are supplied with 3-wire cord sets with grounding-type plugs. Switch plug is inserted directly into outlet and pump plug inserts into opposite end of switch plug.

Hazardous voltage. Pump should always be electrically grounded to a suitable electrical ground such as a grounded water pipe or a properly grounded metallic raceway or ground wire system. Do not modify cord or plug or cut off round ground pin.

8. Secure discharge line before starting pump.

9. If pump discharge line is exposed to outside sub-freezing atmosphere, portion of line exposed must be installed so any water remaining in pipe will drain to the outfall by gravity. Failure to do this can cause water trapped in discharge to freeze which could result in damage to pump.

10. After piping and check valve (if needed) have been installed, unit is ready for operation.

11. Check operation by filling sump with water and observing pump operation through one complete cycle.

Failure to make this operational check

may lead to flooding and premature failure.

NOTICE: This unit is not designed for applications involving salt

water or brine! Use with salt water or brine will void warranty.

ELECTRICAL

Hazardous Voltage. Can cause severe or

fatal electric shock. Pump is supplied with a grounding con-

ductor and ground ding-type attachment plug. To reduce risk of electric shock, be certain that it is connected only to a properly grounded, grounding type receptacle. Ground terminal on pump cord plug is provided for your protection. DO NOT REMOVE!

OPERATION / MAINTENANCE

Risk of electric shock. Before attempting to check why unit has stopped operating, disconnect power from unit. Do not handle pump with wet hands or when standing on wet or damp surfaces, or in water.

Risk of flooding. If a flexible discharge hose

is used, pump may move when motor starts. If the switch hits the side of the sump, the switch may stick and prevent the pump from starting. Make sure the pump is secured so it cannot move around in sump.

Risk of sudden starts. The pump motor is equipped with automatic resetting thermal protector and may restart unexpectedly.

1. If protector trips, motor may be overloading. Check for

the following problems: A. Not enough back pressure in discharge pipe. B. Voltage too high or too low. C. Wires to motor too small. D. Motor incorrectly connected to power supply wires. E. Defective motor.

2. Shaft seal depends on water for lubrication and cooling.

Do not operate pump unless it is submerged in water as seal may be damaged if allowed to run dry.

3. Motor is equipped with automatic reset thermal protector.

If temperature in motor should rise unduly, switch will cut off all power before damage can be done to motor. When motor has cooled sufficiently, switch will reset automatically and restart motor. If protector trips repeatedly, unplug the pump and remove it; check for cause of difficulty. Low voltage, long extension cords, clogged impeller, very low head or lift, etc., could cause cycling.

4. Pump will not remove all water. If manually operated

pump is operating and suddenly no water comes out discharge hose, shut off unit immediately. Water level is probably very low and unit has broken prime.

NOTICE: For continuous operation, water depth must be at least 5" (127mm) to prevent motor overheating.

AUTOMATIC FLOAT SWITCH INSTALLATION

1. Install pump following installation and operating instructions.

2. Automatic float switch is sealed and factory adjusted for

most home sumps. See Page 1 for switch settings.

3. Be sure that horizontal float switch clearance is 8”. For

best performance of pumps with tethered switches, sump

diameter and sump depth should be at least 14”. For best performance of pumps with vertical switches, sump diameter must be at least 10”.

4. Plug piggyback switch cord into 115V AC outlet. Then, plug pump into piggyback switch cord. NOTICE: Call Customer Service for minimum recommended turn-off level above pump base. Do not allow cord to interfere with float control motion or to drape over pump motor. With electrician's tape or cable ties secure cord to discharge pipe for cord protection.

FLOAT SWITCH OPERATIONAL CHECK

1. Fill the sump with correct amount of water to check operation an tightness of connections. During the first automatic cycle, it may take 30 seconds or more before pump is primed and pumping. Pump will start as indicated in the “Motor, Switch and Cord” Specifications Table, Page

2. Check turn-off position. Pump will stop approximately as indicated in the “Motor, Switch and Cord” Specifications Table, Page 1.

3. If pump does not operate check electrical service. NOTICE: Float switch tether length is set at factory. It is 3-1/2” (89mm) for D125, D133, and D150 Series and 3” (76mm) for D175 Series pumps. Do not change tether length of float switch. Float must swing through its complete arc without interference.
