Why is the overload tripping on my Pentair Hydromatic Control Panel motor starter?
- S
  Samuel ScottJul 27, 2025
  If you're experiencing nuisance tripping of the overload on motor starters or circuit breakers of your Pentair Control Panel, several factors could be at play. Start by checking the pump's amp draw with an amp probe and compare it to the nameplate amps on the pump. The impeller might be locked up due to excessive debris or solids. Also, there may be a possible motor failure due to a fault in the windings, or the pump may be miswired to the terminal block. For three-phase systems, check for voltage and current unbalance, and connect leads for the lowest percent of current unbalance. On single-phase units, check connections and start components.

What to do if Pentair Control Panel pump won't run in Hand position?

  Edward LawrenceJul 31, 2025
  If your Pentair Control Panel's pump isn't running in the Hand position, begin by inspecting the pump circuit breaker and control fuse for any signs of tripping or a blown condition. Ensure that the incoming power voltage and control circuit voltage are within the correct range. Check the overload relay to see if it has tripped; if so, reset it and check the pump current using an amp meter. With the power off, verify the continuity of the motor heat sensor. Confirm that the pump wiring to the control panel matches the schematic. Lastly, check the contactor coil resistance.

Why Pentair Control Panel pump not running in Auto?
- N
  nguyenalexanderAug 4, 2025
  If your Pentair Control Panel's pump isn't running in the Auto position, first, review the checks listed for when the pump doesn't run in Hand position. Ensure the floats are correctly wired to the control panel, verifying the float type (N.O. or N.C.) and connecting them according to the schematic. Confirm that the water level in the system is high enough to activate the floats. If the water level is sufficient, with the power off, disconnect the off and on floats, install jumper wires in their terminal blocks, and turn the power back on to see if the pump runs in Auto. If it runs with the jumpers, the floats are the issue; troubleshoot them with an ohmmeter. If it still doesn't run with jumpers, inspect the Auto circuit wiring in the panel.

Why is my Pentair Hydromatic humming loudly?
- T
  Tiffany Wiggins DDSAug 9, 2025
  If you're experiencing severe humming or chattering of contactors and control relays in your Pentair Control Panel, low voltage might be the cause. Use a voltmeter to check the voltage at both the primary and secondary sides of the control transformer. Ensure that the contactor area is free from dust around the magnet of the coil structure; clean if necessary. Verify that the voltage to the control panel meets the minimum requirement of 85% of full voltage for proper contactor pull-in. Ensure the floats are positioned away from turbulence. If a junction box is present, dry it out, as moisture can cause intermittent relay energization.

What causes a Pentair Hydromatic Control Panel pump to run but not pump down the wet well?
- M
  Michelle CareyAug 13, 2025
  If your Pentair Control Panel's pump runs but fails to pump down the wet well, and if you have a three-phase system, the pump rotation may be incorrect due to reverse sequenced wiring of the pump to the control panel. Additionally, the impeller may be dragging in the volute because of solids; this would be identifiable by a high amperage draw.

What to do if the run light doesn't turn on when the Pentair Hydromatic pump runs?
- L
  lopezbrendaAug 17, 2025
  If the pump connected to your Pentair Control Panel is running, but the run light isn't on, remove the light and check it with an ohmmeter. Also, check the run light wiring.

Why does the run light stay on in my Pentair Control Panel?

  Marie PerezAug 22, 2025
  If the run light on your Pentair Control Panel stays on, the selector switch may be in the Hand position.

Summary

General Information and Safety

Before Installation

Manual contains important safety information for product use. Follow instructions carefully and check local codes.

Electrical Shock Hazard

Risk of serious injury/death/fire. Disconnect all electrical sources. Qualified personnel only. Grounding required.

Biohazard Risk

Risk exists once connected to wastewater. Use proper PPE and handling procedures per OSHA.

Fire and Explosion Hazard

Do not smoke or use open flames. Not intended for hazardous locations.

Cutting Hazard

Serious cutting risk from grinder mechanism. Disconnect power. Use caution.

California Proposition 65 Warning

Product contains chemicals known to cause cancer or birth defects.

Manual Preservation

Keep manual in a safe place for continued safe operation.

Installation Skill Requirements

Specialized skill needed for excavation, pipe fitting, and electrical wiring.

Excavation Safety and Procedures

Locate excavation per local codes, check utilities, avoid buried lines, plan excavation size.

Basin Installation Instructions

Basin System Handling

Avoid dropping, dragging, or using sharp objects to prevent damage to basin or components.

Pad Preparation

Pad requires 4-6 inches fill. Concrete pad with tie-downs ideal. Aggregate must be compacted.

Basin Lifting Procedures

Use nylon/non-damaging slings. Do not use chains/steel cables. Use molded lugs if available.

Installation Electrical Hazard

Improper support of conduit/lines can cause structural failure or expose live wires.

Flooding and Basin Floating Risk

If not tied down, rain/flood may cause basin to float, causing damage.

Positioning and Final Checks

Lower, position, level basin. Mount to anchor bolts. Inspect fiberglass for cuts.

Influent and Discharge Connections

Inlet Connection Procedure

Determine inlet point. Drill hole with piloted hole saw. Seal fiberglass cuts. Insert grommet.

Piloted Hole Saw Warning

Failure to use piloted hole saw can damage basin, causing failure or leaks.

Inlet Pipe Insertion

Lubricate grommet lip. Clean pipe end. Push pipe through. Ensure it doesn't protrude inside.

Discharge Connection

Close shut-off valve. Make discharge connection. Recommend additional shutoff/check valves.

Backfill Instructions
