Electrical Installation
9. Check that the tank is charged no greater than 2 psi (0.1 bar) below the outlet pressure switch setting.
IMPORTANT: Make sure the tank pre-charge pressure never exceeds 80 psi (5.5 bar).
NOTE: Factory outlet pressure switch setting is 40 psi (2.8 bar), therefore maximum tank pre-charge is
38 psi (2.6 bar) for factory settings. If desired, adjust the pressure. Refer to

11.
•
If the incoming supply is above 40 psi (2.8 bar), install a pressure reducing valve on the inlet.
10. Install a pressure relief valve downstream of the system.
IMPORTANT: The system will boost a downstream pressure equal to 55 psi (3.8 bar) + incoming psi.
This discharge must be plumbed to a drain rated for maximum pump output at relief pressure settings.
NOTE: If the discharge plumbing, fixtures, and appliances are not rated for these higher pressures, it is
recommended to install a pressure reducing valve after the pressure tank to limit the max downstream
pressure.
Electrical Installation
Risk of severe injury or death by electrical shock.
•
Always disconnect the electrical power before working on or around the system.
•
Check local electrical and building codes before installation. The installation must be in accordance
with their regulations as well as the most recent National Electrical Code (NEC).
•
Some pumps are supplied with lead wires and are intended to be hardwired using a junction box or
other approved enclosure. The pumps include a grounding connector. To reduce risk of electric
shock, be certain that it is properly connected to ground.
•
Some pumps are supplied with a power cord including a grounding conductor and an integral
grounding-type attachment plug. To reduce risk of electric shock, be certain that it is connected only
to a properly grounded grounding-type receptacle. Do not remove the third prong from the plug.
The third prong is to ground the pump to help prevent possible electric shock hazard.
Employ a licensed electrician to perform all wiring.
1.
Disconnect electrical power at the main breaker.
2. Connect the pump to its own circuit, with no other electric receptacles or equipment in the circuit.
3. Verify that the dedicated branch circuit for the system is equipped with a 15 amp circuit breaker.
4. Check that the power supply corresponds with the electrical rating of the system being installed.
•
Supply voltage must be
5. Plug pump into a properly grounded receptacle.
6. Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
