How do I adjust the pressure switch on my hayward h250 heater


The purpose of the pressure switch is to verify the pool pump is operating properly and water pressure is present in the heating chamber. When water pressure is not present, the heater control system is designed to not allow initiation of flame. The pressure switch is preset at the factory for deck level installations. When the heater is located below the level of the spa or pool, the pressure switch may require an adjustment to compensate for the no-flow static head.

CAUTION: The Hayward Pool Heater is essentially a furnace. A trained technician should be consulted to repair it. DO NOT OPERATE the Hayward Pool Heater without a properly functioning and calibrated water pressure switch. The pressure switch adjustment requires both the pool pump and the heater be operational. As a result, extreme caution should be used during this procedure since sources of energy can not be isolated during the procedure.

The following procedure is recommended to calibrate the pressure switch.

1. The water pressure switch is located behind the front service panel. The pressure switch is typically on the left side, above the burners.
2. Be sure the water filter is clean before making the adjustment.
3. With the pump and heater system switch on, carefully turn the pressure switch adjustment dial clockwise, until a click is heard from the gas valve.
4. Turn the adjustment dial counterclockwise 1/4 turn.
5. Turn the pump off and on several times. The heater should shut off immediately when the pump is shut off. If the heater fails to shut down when the pump is off, repeat the steps above until the pressure switch is properly adjusted.
6. If the adjustment process fails to produce proper results the pressure switch should be replaced.

Well Pressure Switch Adjustment Water Well Problems


1fa4b10.jpgIf you have a water well to supply your water needs, then you also have a well pump is some form and a well pressure switch that controls the water well pump and the pressures that it turns on and off at. Making the adjustments to this switch can be confusing, I will try to take away some of the confusion for you. There are many types of well pressure switches made. I will describe the adjustment of the most common type of switch and you can possibly translate from there if you have a different type of well pump pressure switch.

  1. Turn off the power to the well pump before making any adjustments. The blue flash from the arc when you short out the power is scary and leaves you seeing stars for a time.
  2. Drain all of the water pressure from the system and check that you have air pressure in your well pump pressure tank. If you intend to set the cut in of the pump at 30 PSI then make sure there is 28 PSI in the air part of the tank. Always 2 PSI less than your cut in pressure.
  3. Start the pump, run water, and then observe the pressures as the pump starts and stops. Remove power when adjusting to avoid the blue flash…you are working in close proximity to the electrical contacts of the switch.
  4. To raise the cut in pressure turn the taller center nut down to increase the spring pressure. This will start the pump at a higher pressure. To lower the start pressure turn the nut up or counter clockwise.
  5. To change the differential pressure, the difference between the start and stop pressures, you need to adjust the smaller nut that is on the side of the pressure switch. Turning this nut down will increase the differential pressure and likewise turning this nut counter clockwise or up will lower the differential pressure.

This process can take some time, but it will be worth it to have your pump and water system operating efficiently. You also can set the well water pressures to your liking.
This is a basic guide to help you fine tune your water well pump and your well pump pressure tank, along with your water pump pressure switch, so that they all work together to give you a good stable supply of well water.

Low Water Pressure This video will give step-by step instructions on how to adjust a water pressure switch. Note the procedure for pre-charging the pressure tank. The cut-in and cut-out adjustments on the switch are made with the electric on, so be mindful of working around live wires and contacts on the swithc.

My compressor comes up to 150 pounds and when it supposed to go to cycle mode it tries to pump again and get stuck between the two modes. it goes cylcle pump cylce pump.


The pressure switch will usually not let the compessor cut back in untill the pressure drops about 20 psi from cut-out pressure. This differntial can be adjusted by turning the differential adjustment screw. I would check that the switch is not faulty first. Look for switch model number under the cover and look for factory cut-out pressure. If the pressure range is different from factory specs, suspect switch is failing, or someone has tried to adjust the pressure. Dont take a chance with possible faulty switch on this expensive compressor. Switch is adjustable but you can replace for about $50. Good luck

How do i set the low pressure on the flotec switch


your pump should have a 20lb seperation ie. pump turns on at 20lb and off at 40lb or on at 50lb off at 70lb. under the cover of the switch theres two screws with springs under them.dont mess with the small one.the large one if you screw it down (right) will increase the pressure while maintaining the 20lb separation. one thing to keep in mind its fine to adjust the pressure BUT at the same time the air pressure in the tank needs to be adjusted to two lbs below the cut in pressure of the pump.

I believe the directions are in the top of the cover of the switch

The nut on the larger spring in the pump pressure switch: Usually the larger nut in the pump pressure control switch adjusts the pump cut-on ("cut-in") AND pump cut-off pressures simultaneously. This is the left-hand spring (and nut) in our photo. That means that whatever the gap is between the cut-on pressure and the cut-off pressure, that gap is maintained, but the entire operating range of the pump is raised or lowered. Turning the large nut clockwise RAISES BOTH the cut-on and cut-off pressures. So turning the large nut clockwise shifts the whole operating pressure range of the pump UP to HIGHER pressures.
Conversely, turning the large nut counter-clockwise will lower the whole pump operating range. This is the simplest adjustment to make.
Photo (left) courtesy of a reader.
The nut atop the smaller spring in the pump pressure switch: this nut is used to narrow or widen the gap between the pump cut-on and pump cut-off pressures. This is the right-hand spring (and nut) in our photo).

Turning the small nut clockwise (tighter) will RAISE the CUT-OFF pressure, and vice versa, loosening or turning the nut counter-clockwise will lower the cut-off pressure. Watch out! If you loosen this nut too much you can set the cut-off pressure below the cut-on pressure and the pump will turn on and run forever (or until it burns up.)
Which nut to turn in the pump pressure switch control, and which direction to turn it, are usually visible on a label inside the pressure switch cover. Above we show photos of a common Square D water pump pressure control switch (Schneider Electric) and the label with pump control adjustment details. [Click to enlarge].
Here are Example Pump Pressure Switch Adjustment Instructions from Square -D Understanding how pump pressure control switches work and which way to turn which of the two nuts in the control can be confusing.
On a Square-D Pumptrol® 9013FSF-2 pump pressure switch, for example, Square D tells us that we
  • Turn the Range Nut #1 (the larger spring and nut) clockwise (to the right or "down") to raise [both] cut-on and cut-off pressures. This is "tightening the nut down" against the spring. ("Rightie-tightie, leftie-loosie" as Mara Gieseke says to her kids). Thanks to reader Rise for this clarification.

    In other words, adjusting the pressure on this spring shifts the whole operating range of the switch up or down, but keeps the difference between cut-in and cut-out the same, whatever it happens to be (typically it's about 20 psi from the factory.)

    If you want the pump to turn ON (cut-in) sooner
    , that is, at a higher water pressure, turn the nut clockwise or "tighter".

    If you want the water pump to turn ON (cut-in) later, that is, at a lower water pressure, turn the nut counterclockwise or "looser".

  • Turn the Differential Nut #2 (the smaller spring and nut) clockwise to raise the cut-out pressure.

    If you want the water pump to turn OFF (cut out or cut-off) at a higher water pressure, turn this nut clockwise or "tighter".

    If you want the water pump to turn OFF (cut out or cut-off) at a lower water pressure, turn this nut counter clockwise or "looser"

    Here is why the small nut is called the "Differential"

Pressure switch


Remove cap from pressure switch (small nut on top). You will see 3 threaded studs with springs held down by nuts at the end opposite from wired connections. Avoid wired connections with tools and fingers! The center sprung nut adjusts the ON AND OFF pressure settings. Clockwise (tightening down on spring) increases the pressure setting. One of the outside springs controls nothing - note that it has no connection to the switch moving parts. The other one adjusts the OFF setting. So adjust the center one until the ON pressure is 30 psi and then adjust the OFF setting until the pump cuts out at 50 psi. If you have an expansion tank, set this to 2 psi below the OFF setting. (If you have manual for the pump, check the pressure settings in the tables given for your pump.)
If this isn't what you need, please post more info!

Hi,
The problem is that the pressure switch is not adjusted properly...
You need to turn the taller screw down so that the pressure switch kicks the pump on sooner...

I have a Guundfos CHIE 4 circulation pump that is constantly running. I closed the valve on the pressure side but is still runs. On a previous post I was told it "may have lost its prime". The pump is...


You have a defective pressure switch.But replacing the switch. Do the following; Open the pressure switch cover, and find the two adjusting nuts. One is for the cut-off pressure (40psi) and the other is for the cut-in pressure (20 psi). Adjust the the nut with a longer stem counter clockwise (loose) with the pump running. Take care not to touch the power line attach
to it. Continue the adjustment until the pump stops,
at 40 psi. Then, observe - Pump must stop once the
pressure is attained. Then, open the valve until it
start (20psi).. Then you can adjust the other nut to
cut in at 20 psi.
To prime the pump; open and fill the priming port full
with water.and replace the priming port plug. Set
the water flow control valve at full close position.
Switch the power on to run the pump and slowly
open the control valve to appropriate setting such
that the pump doesn't lost the suction. Send your e-
mail for further comment. God bless u
