WARNING

indicates a hazard which, if not avoided, could result in death or serious injury.

CAUTION

indicates a hazard which, if not avoided, could result in minor or moderate injury.

NOTICE addresses practices not related to personal injury. The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and the tags and decals affixed to the unit are, therefore, not all-inclusive. If you use a procedure or operating technique that the manufacturer does not specifically recommend, you must satisfy yourself that it is safe for you and others. You must also make sure that the procedure or operating technique that you choose does not render the system unsafe. Electrically powered sewage pumps normally give many years of trouble-free service when correctly installed, maintained, and used. However, unusual circumstances (interruption of power to the pump, large solids 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 damage, consult your dealer about installing a secondary sewage pump or a high water alarm. See Troubleshooting in this manual for information about common sewage pump problems and remedies. For more information, see your retailer, call Hydromatic® customer service at 1-888-957-8677 or visit our web site at hydromatic.com.

Installation

Thank you for purchasing this HYDROMATIC® pump. To help ensure years of trouble-free operation, please read the manual carefully. Before installation, check your local electrical and plumbing codes. A typical sewage pump installation is shown below.

Cord Lift Warning

WARNING

Risk of electrical shock. Can burn or kill. Do not lift pump by power cord.

Risk of electrical shock and fire.

A ttempting to lift or support the pump by the power cord can damage cord and cord connections, expose bare wires, and cause a fire or electrical shock.
Use handle on top of pump for all lifting or lowering of pump. Disconnect the power to the pump before doing any work on it or attempting to remove it from the pit.
Lifting or supporting the pump by the power cord will void the warranty.

Follow these guidelines for installation

Provide properly sized sump (see Specifications).
D o not set pump directly on the bottom of sump pit if it is not solid. Raise the pump by using bricks or concrete blocks underneath it.
M ake sure sump is free of string, cloth, nails, gravel, etc. before installing pump.
D o not remove ground pin from electrical plug.
D o not use an extension cord to operate this pump.
For proper automatic operation, make sure the pump power cord is plugged into the piggyback receptacle on the switch cord. Three phase models must be properly connected to a suitable control panel. D o not cut, crimp, or bend single phase switch power cord (15). The vent tube needs to “breathe” for proper operation of switch. This may cause pump failure and void warranty.
Use steel or plastic pipe for all connecting lines between pump and sewer outlet.
NOTICE: Some city regulations do not allow installing a pump with plastic pipe. Check local regulations.
Use PTFE pipe thread sealant tape on pipe connections. Do not use ordinary pipe joint compound on plastic pipe or pump. Pipe joint compound can attack plastics and damage pump.
In applications where the pump may sit idle for months at a time, it is recommended that the pump(s) be cycled every month to ensure the pumping system is working properly when needed.
A check valve should be installed horizontally in discharge pipe.
The optional Hydromatic Q Alert is an audible alarm system for high water conditions. It should be installed in every sump for greater protection.
NOTICE: Q Alert is for indoor use only. Other Q Alarm and control panels are available for outdoor use. Contact your Hydromatic distributor for applications.
Use pump partially or completely submerged for pumping waterlike liquids. The pump will pump solid materials up to 2” (spherical) in diameter. Risk of fire. Do not pump flammable liquids. Strong chemicals or salt water should not be pumped without consulting your Hydromatic distributor for proper seals and coatings

Operation

NOTICE: Do not allow pump to run in a dry sump. Doing so will void the warranty and may damage the pump.
An automatic overload protector in the motor will protect the motor from burning out due to overheating/ overloading. When the motor cools down, the overload protector will automatically reset.
If overload trips frequently, check for the cause. It could be a stuck impeller, wrong/low voltage, or electrical failure in motor. If an electrical failure in the motor is suspected, have it serviced by a competent repairman.

Maintenance

Read the following instructions carefully before replacing any parts. Reasonable care and safe methods should be practiced. Check local codes and requirements before installation. Only a competent plumber/electrician should make the installations. Submerge pump in a disinfectant solution (dilute chlorine bleach) for at least one hour before disassembling pump. Check for an obstruction in the impeller by looking through the suction hole of the pump. The shaft should turn freely if unobstructed. Keep fingers, clothing or any material from suction inlet. The steps described in this section should be performed only by an authorized service center.
NOTICE: Read all directions before replacing any parts. Remove pump and switch from power source before servicing.
The numbers in parentheses, such as “(3)” or “(16)”, refer to item numbers used on the Repair Parts diagram.

Replacing diaphragm switch

From switch housing (15) remove screw (14) from housing. Replace with new switch. Insert screw (14) into housing (15) and tighten. Plug pump power cord into the piggyback receptacle on the switch cord, and then switch plug into correct power source.

Checking motor operation

Plug power cord directly in power source to check motor operation. Motor should start and run smoothly. If motor does not start, pump must be dismantled and motor checked. Be certain to unplug cord before disconnecting any wires.

Checking motor stator

Remove plug (21) from top of housing (19) and pour oil into a clean glass container. There are approximately two quarts of oil in the motor housing. If oil is clear, it will indicate motor is not burned and there has been no water leak into the motor. If oil is black, it will indicate a burned stator. If oil is cloudy, it will indicate water in motor oil, so all seals should be replaced. Remove bolts (17) to separate volute case (12) from motor housing. Remove O-ring (18) and seal plate (11) from motor housing. Remove bolts to separate motorstator from rotor. If stator is visibly burned, it must be replaced. If stator is not burned but the oil shows signs of water, stator can be checked with the ohmmeter to see if it can be used.

Ground check

Set ohmmeter scale to R X 1 scale and check meter by putting both meter leads together and adjusting the needle knob until meter reads zero. If meter cannot be adjusted to zero, the batteries in meter must be replaced.

NOTICE: Always reset meter to zero [0] when going to a new scale before making any measurements.
If wire is OK, meter needle will go to near zero and stay there. If meter needle does not move, the wire has an open and the wire must be repaired or replaced. Connect one meter lead to one blade terminal of stator and touch other meter lead to motor stator housing (4). If the resistance to the ground is less than 500,000 ohms, stator must be dried out before retesting. To dry out, place pump in 220 degree oven for four hours. Recheck after motor cools. If motor is thoroughly dry, needle of ohmmeter will not move on the ground check. This indicates a reading of 50 megohms or higher. When making the ground check, if the needle goes to zero, the motor has a wire touching the stator shell at some place and the stator will have to be replaced.
NOTICE: If motor shows a satisfactory ground check then the winding resistance must be checked.

Winding resistance test

Use ohmmeter with scale set to R X 1 scale. On this scale, meter reads directly in ohms. Recheck to zero [0] before making a reading on the winding.

NOTICE: If water is found in motor, seal should be replaced.

Replacing seal

Hold rotor. On 3 phase motors only, remove the impeller screw and impeller washer. Unscrew impeller (13). Tap on end of shaft with plastic or rubber hammer. This will push the rotating seal (10) from shaft and also push lower bearing from seal plate. Clean seal plate (11) and motor housing (19) thoroughly. All sand and dirt must be removed. Remove stationary ceramic seat of seal (10) from seal plate. Push new ceramic seat into seal plate. Use O-ring Lube on rubber ring. Replace rotor in seal plate (11). Use care in putting shaft through ceramic seat to be sure it is not chipped. Inspect seal after shaft is in place. If seal has been chipped it must be replaced. Do not replace rotating part of seal until the balance of the pump is assembled.

Bearings

When the pump rotor has been removed, check bearings before replacing. If bearings are rusted or rough when turned, they should be replaced. When installing a replacement bearing, press only on the inner face. If a press is not available, bearings can be tapped on, using a sleeve that bears only on the inner face.
NOTICE: Never pound on the outer face of the bearing as this will cause bearing damage.

Reassembly

Push the new rotor shaft and ball bearing assembly into the seal plate. (Note that the replacement rotor must be of the same manufacture as the existing stator, or vice versa.) Reassemble the motor (4) to the seal plate (11) with the four long cap screws. Be sure to tighten down the bolts evenly and firmly to prevent cocking of the stator. An uneven assembly can cause the rotor to rub the motor causing the motor to short.
Press the new ceramic seal (10) in place with the rubber ring facing the impeller. This should have a thin oil (dielectric, same as in motor housing) coating.
NOTICE: Ceramic must be kept clean. Any dirt will cause seal failure.
Start the impeller (13) on the shaft one to two turns; then, add a drop of 2Loctite® #243 to the impeller threads and screw the impeller hand tight. The impeller will force the ceramic seal into position. The shaft should be free of dirt, grease, etc., or the Loctite® will not hold as designed. Replace impeller washer and impeller screw to the shaft on three phase models. 2 Henkel Corporation, Germany
NOTICE: Loctite® overrun onto the seal or bearing will result in shaft seizure.
R emove the old seal ring (18) and stretch on new ring with O-ring lube. D o not roll the ring onto seal plate or water leakage into the motor housing will result.
Fasten the ground wire inside the motor housing and tuck wires up into the housing to prevent rubbing on the rotor; then assemble housing (19) to volute (12) with bolts (17).
Before filling the motor housing with oil, a seal leak test should be performed. Apply 7 to 8 pounds of air pressure in the 1/4″ NPT tap (21) on the top of the motor cover and seal chamber.
NOTICE Too much pressure will damage the seal. Seal would have to be replaced. Then submerge the pump in water and check for leaks. If a leak occurs, isolate where it is coming from and correct the problem by replacing the failed part. Hydromatic pumps have a small air vent hole in the impeller cavity to let out trapped air. If this hole becomes plugged, pump may air lock. To break the air lock, use a small screwdriver to clear hole in the impeller cavity.

As a secondary precaution in installations of this type, an 1⁄8” hole should be drilled in the discharge pipe just above the volute. The check valve should be at least 12 inches above pump discharge and mounted horizontally. Do not put check valve directly into pump discharge opening.
NOTICE: In sumps where the pump is operating daily, air locking rarely occurs.

Oil fill

A fter seal leak test is satisfactory, remove unit from water and wipe or blow off any excess water.
D o not put oil in motor with any water present in motor cavity.
Use refined paraffinic transformer oil, 3Shellflex™ 2210 or equivalent.
Shell Oil Company, Texas
Slowly fill oil to 1/8″ over windings in motor housing through opening (21). Use an oil fill tube that will go into holes so that air can escape. Replace plug (21).
NOTICE Do not fill the motor housing completely – allow air space for expansion.
C onnect power cord wires to terminals in panel, or connect power source, and check pump running. Motor should run smoothly and be free of vibration. Pump is ready for operation.
