Pump
Operation
As the motors are oil filled, no
lu bri ca tion or other main te nance
is required.
If a seal failure unit is used, no
at ten tion is necessary as long as
the seal shows sat is fac to ry
operation.
If seal failure is not used, the
pump should be lifted once every
two years and the oil be drained
from the seal cham ber to check
for water.
If the pump is used on a Hydr-O-
Rail system, it should be lifted
once every six months and
checked for cor ro sion and wear.
Generally these pumps give very
re li able service and can be
expected to operate for years
on normal sewage pump ing
without failure.
Lightning:
In some areas where con sid er able
light ning
occurs,
it
is
recommended that a light ning
arrestor be installed at the
control panel.
Complete data on lightning
arrestors and cost is avail able
from the factory. Lightning
ar res tors are good in sur ance
against
damage
to
an
ex pen sive motor.
Starting Systems:
1. Turn H-O-A switch to Off
position, then turn on main
circuit breakers.
2. Open all discharge valves
and al low water to rise in
sump pump.
3. Turn H-O-A switch to Hand
po si tion on one pump and
notice op er a tion. If pump is
noisy and vi brates, rotation is
wrong. To change rotation
interchange any two line leads
to motor. Do not in ter change
main in com ing lines. If duplex
sys tem, check second pump in
the same manner.
4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until
one pump starts. Allow pump
to operate until level drops to
turn-off point.
5. Allow sump level to rise to
start other pump. Notice run
lights on panel; pumps should
alternate on each suc ces sive
cycle of op er a tion.
6. Turn both H-O-A switch es to
Auto position and allow sump
to fill to the over ride control
level.
7. Turn both switches to Auto
po si tion and both pumps
should start and operate
to geth er until level drops to
turn-off point.
8. Repeat this operation cycle
sev er al times before leav ing
the job.
9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire as
sometimes a high leg will
exist. One leg can be
some what higher (5 to 10%)
without caus ing trouble. For
excessive amp draw on one
leg, the power company should
be consulted.
Pump
Maintenance
Servicing Instructions:
IMPORTANT:
Read
all
in struc tions before replacing
any parts.
WARNING: Before han dling
these pumps and controls,
always dis con nect the power
first.
Do not smoke or use sparkable
elec trical devices or flames in a
sep tic (gaseous) or possible
septic sump.
Field Service on Motor:
All submersible motors can be
ser viced (out of warranty) in the
field by any reliable motor service
shop. Any pump (in warranty)
must be re turned to the factory
for service or re paired in an
au tho rized Hydromatic service
center. Charg es will not be
allowed if (in warranty) pump
is taken to a motor repair
shop that is not an authorized
Hydromatic service center.
When field service is per formed
on a pump, these in struc tions
should be carefully followed.
Replacing Stator:
If motor winding is burned or
short ened, it can be rewound or
replaced with new factory wound
stator. Refer to sec tion al drawing
of pump and mo tor and use the
following steps to re move and
replace stator.
1. If stator only is dam aged,
it may not be necessary to
completely dismantle pump as
stator and hous ing can be lifted
from pump without dis turb ing
seals or bear ings.
2. Drain all oil from upper
housing, remove from upper
housing, re move drain plug in
