Frequently Asked Questions
What does the Pentair 355862 do?
It carries the RS-485 communication between your pump's keypad and its drive. If that link fails, the keypad can go blank or throw communication errors even though the drive and keypad themselves are fine.
How do I know if I need this cable?
Typical signs are an unresponsive or blank keypad, intermittent display, or communication error messages. Reseat the connectors first; if the fault persists, the cable is a likely and inexpensive culprit.
Which pumps does it fit?
Pentair IntelliFlo and IntelliPro variable-speed pumps. Confirm your pump family before ordering.
Does it come with the drive-side connector?
Yes — the kit includes the RS-485 replacement connector for the drive end, along with the keypad cable.
Should I replace this before the keypad or drive?
Yes — it's the least expensive part in the communication chain, so it's the smart first thing to try when you have keypad communication problems. Companion parts include keypad 357527Z and the various IntelliFlo drive kits.
Is professional installation required?
Always disconnect power at the breaker before servicing. While this is a low-voltage cable, working inside the drive enclosure is best handled by someone comfortable with pump electronics.
Frequently asked questions
Is a variable speed pump worth it?
Variable speed pumps draw dramatically less power at low speed because energy use falls far faster than flow does. Many jurisdictions now require variable speed for new and replacement residential pool pumps above a certain horsepower, so check local code before buying single-speed.
What is the part number for this pump?
Pentair lists this pump under part number 355862. Quote 355862 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How do I match a pump to my pool?
Work from the plumbing rather than the pool size: line diameter, total dynamic head and the flow your filter and heater can accept all cap the useful pump size. An oversized pump on undersized plumbing wastes power and can exceed the filter's rated flow.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
What do I need to check before installing this pump?
Confirm the voltage, the union or port sizes and the mounting footprint against your existing installation. Pump replacement usually involves electrical connections and may require a licensed electrician depending on local requirements.
Is there a warranty on this pump?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
