General safety
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 retailer about a secondary AC 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 retailer or call Hydromantic customer service at 1-888-957-8677.

  1. Know the pump application, limitations, and potential hazards.
    Do not use in explosive atmospheres. Pump water only with this pump. failure to follow this warning can result in personal injury and/or property damage.

  2. Disconnect power before servicing.

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

  4. Drain all water from system before servicing.
    risk of flooding. if a flexible discharge hose is used, pump may move when motor starts. If it moves far enough so that switch hits side of sump, switch may stick and prevent pump from starting.Make sure pump is secured so it cannot move around in sump.

  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 all connections are secure.

  7. Inspect sump, pump and system components monthly. Keep free of debris and foreign objects. Perform routine maintenance as required. fire Hazard
    – Do not store or rest objects on or near motor or switch linkage. Keep all flammable objects or liquids away from motor.

  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 lighted 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.

  10. When wiring an electrically driven pump, follow all electrical and safety codes, as well as most recent National Electrical Code (NEC) and Occupational Safety and Health Act (OSHA).

  11. This equipment is only for use on 115 volt (single phase) and is equipped with an approved 3-conductor cord and 3-prong, grounding-type plug.
    To reduce risk of electric shock, be certain that it is connected to properly grounded, grounding-type receptacle.
    never connect green (or green and yellow) wire in cord to a live terminal! Where a 2-prong wall receptacle is encountered, it must be replaced with properly grounded 3-prong receptacle installed in accordance with the National Electrical Code and local codes and ordinances.

  12. All wiring should be performed by a qualified electrician.

  13. Make certain that power source conforms to requirements of your equipment.

  14. Protect electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking cord. Replace or repair damaged or worn cords immediately.

  15. Do not touch an operating motor. Modern motors can operate at high temperatures.

  16. Do not handle pump or pump motor with wet hands or when standing on wet or damp surface, or in water.

if your basement has water or moisture on floor, do not walk on wet area until all power has been turned off. if shutoff box is in basement, call electric company to shutoff service to house, or call local fire department for instructions. remove pump and repair or replace. failure to follow this warning can result in fatal electrical shock.
Do not use in hazardous or explosive locations. California Proposition 65 Warning

Installation

PENTAIR P33A1 Hydromatic Pedestal Sump Pump - Fig 1

Installation

  1.  This unit can be installed in sump pit with minimum diameter of 12″ (30cm) and depth of 12″ (30cm). Sump pit may be constructed of tile, concrete, steel or plastic. Check local codes for approved materials.

  2. Install pump on solid, level foundation, as near as possible to center of sump pit. Do not hang pump from discharge pipe or power cord.
    Pump must be level (column must be vertical) when operating. If motor is tilted, internal start/run switch may overheat and damage motor.

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

  4. Thread discharge pipe into pump body carefully to avoid stripping or crossing threads. notice: Do not use ordinary pipe joint compound on plastic pipe or pump. Pipe joint compound can attack plastics and damage pump.

  5. To reduce motor noise and vibrations, a short length of rubber hose (1-5/8″ (41mm) I.D., e.g. radiator hose) can be connected into discharge line near pump using suitable clamps.
    risk of electric shock. Pump is designed for 115V., 60 HZ operation and requires an individual branch circuit of 15 amperes capacity. it is supplied with a 3-wire cord set with grounding-type plug for use in a 3-wire, grounded outlet. Do not cut off the round grounding prong. for safety, outlet must 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.

  6. Locate Float Rod Guide (Key No. 6) about 6″ (16cm) below motor. Clamp guide to column with screw provided. risk of flooding. Be sure that guide is securely clamped so that float rod is vertical and can move up and down freely. If float is angled or binds, pump may not start, allowing flooding to occur.

  7. Screw float onto threaded end of rod. Threads on rod will cut threads into corrosion resistant float.

  8. Insert plain end of float rod up through eye of rod guide.

  9. Slide one rod stop on float rod before passing rod through eye of pump switch. Slide 2nd rod stop on rod after passing through eye of switch. Position 2nd rod stop flush with top of rod.

  10. Position lower rod stop to within 8″(20cm) of switch lever arm. With lower rod stop in this position, pump will automatically cycle at approximately 2-1/2″ (6cm) off and 10-12″ (25-30cm) on. For faster cycling, move lower rod stop closer to switch lever arm.

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

  12. Install an in-line check valve (Hydromatic No. 124410001) to prevent flow backwards through pump after pump shuts off. notice: The check valve should be equipped with an air bleed hole to prevent airlocking the pump. If using a check valve without an air bleed hole, drill a 1/8″ (3.2mm) hole in discharge pipe just above pump body but below the check valve to prevent air locks.

  13. After all piping and controls have been installed, unit is ready for operation.

  14. Run pump through one cycle to check float switch operation.
    the pump motor is equipped with automatic resetting thermal protector and may restart unexpectedly. Protector tripping is an indication of motor overloading as a result of operating pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect motor connections, or a defective motor.

Operation

Do not touch sump pump, pump  odor, water, or discharge piping when pump is connected to electrical power.  always disconnect pump cord (power) before handling.

  1. Plug this unit into a 115V outlet, on an individual branch circuit, with a Class A, 15 amp GFCI (Ground Fault Circuit Interrupter). Consult your local electrician for information and availability.

  2. Fill sump pit with water, pump will start automatically when lower rod stop actuates switch lever arm. When upper rod stop actuates switch lever arm, pump will stop.
    Notice: Do not allow pump to run dry.
    Before attempting to service, always disconnect power from unit.

  3. The motor is equipped with an automatic reset thermal protector to protect unit from overheating. When motor has cooled sufficiently, switch will reset automatically
    and restart motor. Repeated tripping could be  amused by low voltage, long extension cords, clogged impeller, very low head or lift, etc. Cycling of protector will cause eventual motor burnout.

Troubleshooting

Unplug pump from power receptacle before working on pump.

symptom Possible caused(s) corrective action
Motor will not starter run No electrical power Low line voltage Faulty

automatic switch Float or float rod stuck Waterlogged float Motor overload tripped Electrical malfunction| Check fuse, circuit breaker, power cord and electrical outlet. If voltage wiring under recommended minimum, check size of wiring from main source. If OK, contact Electric Company or local Hydro authority. Operate switch manually and replace if inoperative. Check to see float is not rubbing sump wall or float rod rubbing or stuck against sump cover. Replace float if filled with water. If pump has been running and stops before sump is emptied, automatic overload may have tripped. Check inlet screen to be sure impeller is not jammed. If so, free impeller of obstruction.
Check power cord, automatic switch and motor. Replace faulty parts as needed.
Motor runs but pump will not pump| Inlet clogged Discharge line plugged.
Low line voltage  Pump airlocked.
Broken impeller or shaft.| Check inlet and clean if needed. Clear discharge line and check valve for obstruction. Refer to Corrective Action on low line voltage in above section. Drill a 1/8″ (3.2mm) hole in discharge pipe just above pump body but below the check valve. Replace impeller or shaft as needed.
Pump starts and stops too often| Improper positioning of float rod stop Faulty automatic switch| Lower float rod stop. Replace automatic switch.
Pump is noisy| Improper installation Noisy motor| Refer to No. 5 in Installation Instructions. Replace pump.
Pump will not stop running| Debris around float or float rod stuck
