Pump

Servicing

read  the  following  instructions     

carefully before replacing 

any parts. reasonable care 

and safe methods should be 

practiced. check local codes and 

requirements before installation. 

only 

com pe tent 

electrician 

should make the installations.
Servicing should be performed 

only by knowledgeable pump 

 

service contractor or authorized 

service station.
Remove from power source.

WArning: Shock hazard.

1.  Checking power cord. To be 

sure wires are not burned off or 

broken in cord, use ohmmeter 

to check. Set ohmmeter scale 

pointer to r X 1 scale and 

attach one meter lead to white 

cord wire and one meter lead 

to black cord lead, then place 

screwdriver blade across blade 

terminals of plug. if cord is 

oK, meter needle will go to 

zero and stay there. if meter 

needle does not move, this will 

indicate an open wire and cord 

must be replaced.

2.  Checking motor operation. 

When switch cap is off and 

switch is removed, connect 

two 

terminals 

that 

were          

connected to switch together 

and tape. Plug power cord 

in power receptacle to check 

motor operation. motor should 

start and run smoothly. if 

motor does not start, pump 

must be dismantled and 

 

motor checked.

CAuTiOn: 

Be sure to 

unplug cord before continuing 

or reassembly if pump 

 

is  functional.

3.  Checking motor stator. 

if motor does not run when 

tested as described above, the 

stator must be removed from 

the   housing and checked. 

remove plug (12) from top 

of housing, and pour oil in 

container,    preferably glass, 

so that oil can be observed.

  if oil is clear it will indicate 

motor is not burned and there 

has been no water leaking into 

the motor. if oil is cloudy or 

black, it will indicate water in 

the motor or a burned stator.

  after draining oil, remove 

bolts (10) and remove cord 

nut (25) from motor cord (21). 

remove rubber seal ring from 

around cord. Turn cord and 

lift up until seal ring (26) is 

removed. Pry between ears of 

housing (24) to remove from 

base. disconnect motor cord 

from stator and remove bolts 

(2) and plate. Lift stator from 

base. if stator is visibly burned, 

it must be replaced. if stator is 

not burned but the oil shows 

signs of water, stator can 

be

 

checked with the ohmmeter 

to see if it can be reused.

4.  ground  che    ck. Set ohmmeter 

scale pointer to r X 100K 

scale and check meter by 

putting both meter leads 

together and adjusting the 

 

needle knob until meter reads 

zero. if meter cannot be 

adjusted to zero it will indicate 

that batteries in meter must be 

replaced.

  check meter to zero and adjust 

if necessary before making 

any checks on motor.

  Now connect one meter lead 

to one blade terminal of stator 

and touch other meter lead to 

motor stator shell. if needle 

reads below 5 (500,000 ohms) 

stator must be dried out before 

rechecking. To dry out, place 

motor in 220 degree oven 

for four hours. recheck after 

motor cools. if motor is new 

or thoroughly dry, needle 

of      ohmmeter will not move 

on     the ground check: This  

indicates a reading of 50 

megohms or higher. one 

megohm is one million ohms.

  When making the ground 

check, if the needle goes 

to zero the motor in all
