TROuBLESHOOTING GuIdE

Check
No voltage at fuse box.
No voltage at pressure switch.
No voltage at control box.
Cable or splices bad.
Control box incorrectly wired.
Check fuse size against Tables II and III,
Pages 3 and 4.
Check wire size against Table III, Page
4.
Check control box to see if starting
capacitor has blown out.
Check that line voltage is within ±10%
of nameplate rated voltage while motor
is running.
Check control box wiring diagram
against incoming power hookup.
Check drop cable color coding.
Examine all connections and wiring in
control box.
Check for locked rotor in pump.
Check that line voltage is within ±10%
of rated nameplate voltage while motor
is running.
Check temperature of control box.
Compare voltage and horsepower on
motor nameplate with those given on
control box nameplate or on circuit
diagram inside control box cover.
Check wire size against Table III, Page
4.
Consult licensed electrician or qualified
serviceman.
Check all tank connections with soap-
suds for air leaks. Check plumbing
for leaks.
Check for defective switch or switch
out of adjustment.
Pre-charged tanks; check tank pre-
charge air pressure, check for leak
in bladder.
Air over water tanks: check for air
leaks.
Check Air Volume Control (AVC).
Check snifter valve operation.
Raise drop pipe one length at a time
until water stands in pipe.
Measure distance from pressure
switch to tank.

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
diagrams, Pages 6 through 8).
Install correct fuse or time delay fuse.
Install correct size wire.
Replace starting capacitor.
If voltage variation is greater than ±10%, call
power company to adjust voltage.
Reconnect leads to match wiring diagram in
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 reinstall-
ing pump.
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.
Install correct wire size.
Do not attempt to disassemble pump or motor.
System must be air and water tight.
Re-adjust or replace pressure switch.
Pre-charge tanks: adjust air pressure to 2
PSI (13.8 kPa) less than pump cut-in pres-
sure (when there is no water pressure on
system).
Replace bladder if necessary.
Air over water tanks: repair or replace tanks;
replace snifter valves if necessary.
Replace pipe above that point.
Move switch to within one foot of tank.
