Inline Pressure Boosting System
This condition will result in a pressure drop from 80 or 85 psi down to 40 psi before the
pump initially turns ON (this DROP is due to the stored water being discharged from the
pressure tank). If the installer desires to change this from a 80 psi-40 psi drop to a 80psi-
50psi drop, the discharge pressure switch can be adjusted to turn the pump ON when the
discharge pressure reaches 50psi. Follow these steps:
1. Disconnect the unit from incoming power.
2. Remove the (6) control cap screws and remove the cap (note: be careful when
removing the control cap as there is an electrical cable attached to the head.)
3. Using a 7/32" hex wrench, turn the internal discharge pressure switch screw
clockwise one-full turn. This should raise the switch cutoff by 10-12 psi.
4. Replace the control cap and re-install (6) screws.
5. Adjust pressure tank to 48 psi (always 2 psi lower than cut-in pressure)
Note: NEVER adjust the discharge pressure switch to a setting HIGHER than the SUM of
your minimum incoming pressure + 40 psi as doing so may result in a fault (flashing RED).

Draining the System:

Disconnecting the pump will not necessarily drain all other parts of the piping system.
If there are any concerns with the proper procedure or necessity of draining the suction
plumbing, contact a water systems professional. All Inline systems, piping, and water
tanks exposed to freezing weather should be drained when appropriate. There is a drain
plug on the bottom of the unit that may be used to drain the disabled system. If there are
any concerns with the proper procedure to drain the system's pressure tank, contact the
tank manufacturer for assistance.
