Jet Pump and 2-Wire Submersible Pump (No Control Box) Pressure Switch Replacement (continued)
Control Box Installation
3-Wire pumps require a control box. However, replacing the pressure switch on your
system does not necessarily mean you need to replace the control box. To replace the
switch, complete the steps below. If installing a new control box, disconnect the old
wires and reconnect them in the same way to the new box – making sure of the
following connections:
• The red, black, and yellow pump wires are connected to the “R”,”B”, and “Y”
terminals in the control box.
• The wires to the pressure switch are connected to the terminals “L1” and “L2”.
• The green ground wires from the pump and to the pressure switch are connected
to each of the grounding screws provided.
• See REMOVING THE EXISTING SWITCH section on Page 1 for installation
instructions.
Adjusting Switch and Tank Pressure for Maximum Performance
To increase the overall water pressure in your system:
1. Disconnect power supply and drain all water from the tank.
2. Remove the switch cover.
3. Turn the nut on the LARGE adjustment spring (B), clockwise 360° (1 full turn) for each 3 PSI you wish to increase your system’s
water pressure. If you would like to adjust the “Cut-Out” pressure only, you will need to adjust the nut on the SMALL spring (A)
clockwise 360° (1 full turn) for each 3 PSI you wish to increase your system’s “Cut-Out” water pressure. For decreasing pressure,
turn the nuts counterclockwise. See Figure 1.
4. Check the tank’s air pressure with a tire gauge and add or bleed off air (see CHECKING THE AIR PRESSURE section on page 1) until
tank pressure is 2 PSI below the new cut-in setting of your pressure switch.
5. Replace the switch cover and reconnect the power. Test the system several cycles for proper operation.
6. If the system has a built-in water pressure gauge, use it, or use a portable water pressure gauge to verify new system pressure.
NOTE: For Switch with Low-Level Cut Off Arm (Model PPSL3050)
To start your pump using a low level cut off pressure switch, you must hold the lever in the start position until the pump has reached
the required cut-in pressure. This means your pressure must reach 30 psi before you can release the lever into the automatic position.
Failure to follow this step will cause the pump to not work properly. These positions are noted on the side of the pressure switch cover.
3-Wire Submersible Pump (Control Box) Pressure Switch Replacement
IMPORTANT: Your wire colors and control box configuration may vary.
However, if you have a control box, you will always have three wires coming from
the pump and two wires coming from the pressure switch. For further control
box questions, please contact the control box manufacturer.
!
IMPORTANT: Do not make any adjustments to the springs on the pressure switch without first testing the operation of the
pump and the switch at the factory settings. If you are not familiar with well systems, call 1-800-346-7611 for assistance, or
consult with a licensed plumber or electrician.
!
IMPORTANT: When adjusting the pressure switch, it is critical to keep track of exactly how many turns of the nut(s) have been
made. If adjustments are made and need to be undone, it will be difficult to adjust back to factory settings
