PENTAIR 2975PC Submersible Sump Pump Owner’s Manual

PENTAIR 2975PC Submersible Sump Pump

Installation

• Know the pump application, limitations, and potential hazards.
• Disconnect the power before servicing.
• Release all pressure within the system before servicing any component.
• Drain all water from the system before servicing.
• Secure the discharge line before starting the pump.
• An unsecured discharge line will whip, possibly causing personal injury and/or property damage.
• Check the hoses for a weak or worn condition before each use. Make certain all connections are secure.
• Periodically inspect the sump, pump and system components. Keep free of debris and foreign objects. Perform routine maintenance as required.
• Provide a means of pressure relief for pumps whose discharge line can be shut-off or obstructed.

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.

Personal Safety:

• Wear safety glasses at all times when working with pumps.
• Keep the work area clean, uncluttered and properly lighted – replace all unused tools and equipment.
• Keep visitors at a safe distance from work area.
• Make the workshop child-proof – with padlocks, master switches, and by removing starter keys.
• When wiring an electrically driven pump, follow all electrical and safety codes that apply.
• 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

Operation

• If a flexible discharge hose is used, make sure the pump is secured in the sump to prevent movement. Do not use a 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.
• The discharge piping should be as short as possible to reduce pipe friction losses. Discharge pipe diameter should be equal to or larger than the discharge size of the pump. Smaller pipe diameters will restrict the capacity of the pump and reduce performance.
• Secure the discharge line before starting the pump.
• To reduce motor noise and vibrations, a short length of rubber hose (e.g. radiator hose) can be connected into the discharge line near the pump using suitable clamps.
• If the pump discharge line is exposed to outside sub-freezing atmosphere, the portion of the line exposed must be installed so any water remaining in the pipe will drain to the outfall by gravity. Failure to do this can cause any water trapped in the discharge line to freeze which could result in damage to pump.

Automatic Float Switch – Installation

• Install the pump following the previous instructions.
• The automatic float switch is sealed and factory adjusted for most home sumps. See Specifications for the switch settings.
• NOTICE Minimum recommended turn-off level above pump base is 5” (13 cm).
• Be sure the horizontal float switch clearance is 8” (20 cm). For best performance of pumps with tethered switches, the sump diameter and sump depth should be at least 12” (30 cm).
• Risk of flooding. Can cause personal injury and/or property damage.
• May lead to improper operation or premature failure.
• If a flexible discharge hose is used, the pump may move when the 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 the sump.
• Plug the piggyback switch cord into a 115V AC outlet. Then, plug the pump into the plug on the piggyback switch cord.
• Do not allow the cord to interfere with the float control motion or to drape over the pump motor. With electrician’s tape or cable ties, secure the cord to the discharge pipe for cord protection.

Maintenance

Float Switch – Operational Check

• Fill the sump with the correct amount of water to check the operation and tightness of the connections.
• During the first automatic cycle, it may take 30 seconds or more before the pump is primed and pumping. The pump will start as indicated in Specifications.
• Check the turn-off position. The pump will stop approximately as indicated in Specifications.
• If the pump does not operate, check the electrical service.

Float Switch Tether Length

To Clean the Impeller

• Follow the steps shown below. To reassemble pump, reverse the sequence.
• Risk of electric shock. Can shock, burn or kill. Before removing the pump from the sump for service, always disconnect the electrical power source to the pump.
• Do not raise, lower, or carry pump by the power cord. Use the handle that is provided on the pump.

Airlocks

• When a pump airlocks, it runs but does not move any water. An airlock will cause the pump to overheat and fail.
• To avoid this problem, drill an 1/8” (3.2 mm) hole in the discharge pipe just above the pump outlet but below the check valve. Leakage from the anti-airlock hole is ‘normal.’
• If you suspect an airlock, unplug the pump, clean out the anti-airlock hole with a paper clip or a piece of wire, and restart the pump.

Warranty

Limited Warranty
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011. SIMER warrants to the original consumer purchaser (“Purchaser” or “You”) that its products are free from defects in material and workmanship for a period of twelve (12) months from the date of the original consumer purchase. If, within twelve (12) months from the original consumer purchase, any such product shall prove to be defective, it shall be repaired or replaced at SIMER’s option, subject to the terms and conditions set forth herein. Note that this limited warranty applies to manufacturing defects only and not to ordinary wear and tear. All mechanical devices need periodic parts and service to perform well. This limited warranty does not cover repair when normal use has exhausted the life of a part or the equipment. The original purchase receipt and product warranty information label are required to determine warranty eligibility. Eligibility is based on purchase date of original product – not the date of replacement under warranty. The warranty is limited to repair or replacement of original purchased product only, not replacement product (i.e. one warranty replacement allowed per purchase). Purchaser pays all removal, installation, labor, shipping, and incidental charges. For parts or troubleshooting assistance, DO NOT return product to your retail store. Contact SIMER Customer Service at 800-468-7867. Claims made under this warranty shall be made by returning the product (except sewage pumps, see below) to the retail outlet where it was purchased or to the factory immediately after the discovery of any alleged defect. SIMER will subsequently take corrective action as promptly as reasonably possible. No requests for service will be accepted if received more than 30 days after the warranty expires. Warranty is not transferable and does not apply to products used in commercial/rental applications

Sewage Pumps

• DO NOT return a sewage pump (that has been installed) to your retail store. Contact SIMER Customer Service. Sewage pumps that have seen service and been removed carry a contamination hazard with them.

If your sewage pump has failed:

• Wear rubber gloves when handling the pump;
• For warranty purposes, return the pump’s cord tag and original receipt of purchase to the retail store;
• Dispose of the pump according to local disposal ordinances.
