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. If 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 clockwise).
3. Open several faucets 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 will 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 counter-clockwise) the pressure regulator and
water will 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 if so, pump should
be operated in this manner.
LUBRICATION
It is not necessary to lubricate the pump or its motor. The
motor has two ball bearings lubricated for life. The me-
chanical shaft seal in the pump is water lubricated and 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 tubing and turn
(loosen) it 180° on the 1/4" pipe fitting in the tank. This will
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 pump
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 diffuser, 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 until 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.
