OPERATION
MAINTENANCE
PRIMING
THE
SHALLOW
WELL
PUMP
TO PREVENT
DAMAGE
TO INTERNAL
PARTS, DO NOT
START MOTOR
UNTIL
PUMP
HAS BEEN FILLED WITH
WATER.
1. Be sure pressure regulator located on pump body is open
at all times during priming and running. Turn counter-
clockwise all the way.
2. Remove priming
plug. Fill pump with water. Replace
priming plug. ff a priming tee and plug have been pro-
vided for a long horizontal run, be sure this line is filled
and the plug replaced,
using pipe compound
on plug
threads. See Figure 7, Page 7.
3. Start the pump and run for approximately
thirty (30) sec-
onds. Stop pump, remove
prime plug and refill with
water. Replace prime plug and gauge and restart pump.
Water will be pumped
in a few minutes, the time de-
pending on the depth to water and length of horizontal
run. If pump does not prime, check for a possible leak on
the suction side of pump. Check to be sure suction lift -
distance
from water level to pump - does not exceed
twenty (20) feet.
PRIMING
THE
DEEP
WELL
PUMP
TO PREVENT
DAMAGE
TO INTERNAL
PARTS, DO NOT
START
MOTOR
UNTIL
PUMP
HAS BEEN FILLED WITH
WATER.
1. Remove the priming plug. Open pressure regulator (turn
counter-clockwise)
located on the pump body. Fill pump
and piping with water and replace plug and tighten only
until it seals.
NOTICE:
For location
of pressure
regulator,
see Installation
Diagrams
on Pages 4 and 5.
2. Close the pressure
regulator
(turn clock-vflse).
3. Open
several fancets in the house or near the tank to pre-
vent pressure
build up in tank.
4. Start pump.
Pressure
should build up rapidly as the jet and
pump
prime.
Pressure
vddl be in excess
of 60 pounds.
If
this fails to happen,
repeat
2 and 3 above.
5. Once unit has primed
on pressure
has stabilized,
slowly
open (turn cotmter-clockw'tse)
the pressure
regulator
and
water vdfll begin
to be pumped
into tank.
6. Continue
to open
pressure
regulator
until pressure
falters
(becomes
erratic).
At this point,
close (turn
clockwise)
the pressure
regulator
slightly
until pressure
stabilizes.
Close faucets
and allow pump
to pressurize
the tank and
shut off.
7. To insure
pump
is operating
properly,
alternately
open
and close faucets
in system.
With faucets open,
pressure
will drop
until pressure
switch
starts
pump;
and with
faucets
closed,
pressure
will build
up until
pressure
switch
shuts off pump.
8. There
are certain
conditions
of deep
well
operation
whereby
the pressure
regulator
can be completely
open
without
any faltering
of pressure
and ff so, pump
should
be operated
in this manner.
LUBRICATION
It is not necessary
to lubricate
the pump
or its motor.
The
motor
has two
bali bearings
lubricated
for life. The
me-
chanical
shaft seal in the pump
is water
lubricated
mad self-
adjusting.
DRAINING
FOR WINTER
When
the pump
is to be disconnected
from service,
or is in
danger
of freezing,
it should
be drained.
The pump
has a
drain
cock
which
must
be opened.
Remove
the priming
plug to vent the pump.
Drain the pressure
tank. Drain all pip-
ing to a point below
the freeze
line.
To drain an air volume
control,
remove
AVC tnbing
and turn
(loosen)
it 180 ° on the 1/4" pipe fitting in the tank. This vdll
permit
any water
remaining
in the air volume
control
to
drain back into the tank.
DISASSEMBLY
AND ASSEMBLY
OF PUMP
The SEARS Hydroglass*
pump
is designed
for ease in servic-
ing and maintenance.
1. Disassemble
pump
as follows:
A. Disconnect
power.
B. Drain
pump
by opening
drain
cock
on bottom
of
pump
body and remove
pressure
switch
tubing
from
fitting on top of pump
body. This will allow air to re-
place the water
in the pump.
C. Remove
clamp,
Key No. 11, Page 16, which
holds the
two pump
halves together.
D. Remove pump base mounting
bolts. Motor assembly and
back half of pump
can now be pulled away from pttmp
front half. Carefully remove
O-Ring and place in a clean
area. Inside of pump
is now accessible
for service.
2. Reassembly
of pump.
A. With a clean cloth, wipe
out all foreign
material
from
the large O-Ring groove
on the pump
back half. Also
wipe clean the large O-Ring and also the small O-Ring,
Key No. 6, Page 16 on the difflaser, Key No. 10, Page
16. This will insure
a good tight seal.
B. Lubricate
O-Rings with petroleum
jelly for ease of as-
sembly. Place large O-Ring in groove.
C. Pump halves
can now
be slid together
tmtil they are
parallel
and are as close together
as possible.
D. BE SURE inside
of clamp
is clean.
Place
clamp
on
pump
halves
and snug up. Alternately
tighten clamp
screw and tap around
outside
of clamp
with a plastic
mallet. This will insure
proper
seating
of O-Ring and
clamp.
E. Assemble
base mounting
bolts.
Reconnect
pressure
switch
tubing
and tighten
drain cock.
F. Reprime
pump
and turn on power.
