TROUBLESHOOTING GUIDE

CORRECTIVE ACTION
Replace blown fuses.
Replace faulty pressure switch.
Rewire supply to control box.
Consult licensed electrician or serviceman.
Reconnect control box correctly (see Wiring
Installation Diagrams).
Install correct fuse or time delay fuse.
Install correct size wire.
Replace starting capacitor. Replace start relay if
defective.
If voltage variation is greater than ±10%, call power
company or local hydro authority to adjust voltage.
Reconnect leads to match wiring diagram in control
box cover. Reconnect power supply wires so wire color
code matches motor lead color code.
Disconnect power and repair or replace faulty wire.
If necessary, pull pump (make all possible above ground
checks first). If pump is locked, replace it. Clean well
of all sand or lime before reinstalling pump.
Do not attempt to disassemble pump or motor.
If voltage variation is more than ±10%, call power
company to adjust voltage.
Do not mount control box in direct sunlight.
Replace control box if numbers do not match.
Use only control box designed for use with pump.
Install correct wire size.
System must be air and water tight.
Re-adjust or replace pressure switch.
Replace check valves if necessary.
Pre-charge tanks: adjust air pressure to 2 PSI (13.8 kPa)
less than pump cut-in pressure (when there is no water
pressure on system). Replace bladder if necessary.
Air over water tanks: repair or replace tanks,
replace AVC if necessary.
Replace pipe above that point.
Move switch to within 1' (.3M) of tank.
If stuck, free valve; if installed backwards, reverse it.
Lower pump further into well (but at least 5' (1.5M)
above bottom of well). Throttle pump discharge until
discharge equals recovery rate of well. NOTICE: Running
pump while airlocked can cause loss of prime and
seriously damage pump.
Install larger wire from meter to control box. Install larger
wire from control box to pump. If necessary, have power
company raise supply voltage.
Clean or replace as necessary.
Free check valve.
Replace pump.
Remove bleeder orifices; plug tees. Be sure plugged tees
do not leak. If necessary, separate gas from air before
it enters pressure tank.
Replace control if necessary.
