Replacement Parts List

1. Keep the pump and motor properly lubricated.
2. If the system is to be exposed to freezing temperatures,
drain the pump.
PERIODIC INSPECTION
Inspect the pump regularly for leaking seals, worn gaskets,
and loose or damaged components. Replace or repair as
required.
Refer to the following manuals for additional repair instruc-
tions for Bell & Gossett Iron & Bronze Booster Pumps:

SYSTEM PREPARATION1
Prior to pump start up, closed heating and cooling systems
should be flushed with clean water and drained. The system
should then be filled with clean water having a PH between 7
and 9.
LUBRICATION1
Although the new B&G pumps are test run at the factory, they
must be lubricated thoroughly before being placed in opera-
tion. Bell & Gossett supplies a high quality lubricant specifi-
cally for this purpose which can be purchased from any B&G
Representative (Part No. L23401). Proper lubrication proce-
durs are as follows:
1.
PUMP BEARINGS – Fill the bearing frame according to the
oiling instructions decal. At the time of installation, add
approximately 1 oz. of B&G #20 weight non-detergent oil.
An SAE 20 (non-detergent) or 10W-30 oil may be substituted.
Re-lubrication is required at the start of each heating sea-
son, or every three months for continuous service. Re-
lubricate with 1 teaspoon of oil. More frequent lubrication
may be required under adverse conditions such as high
ambient temperatures. Less frequent lubrication is required
if oil overflows from the reservoir.
2.
MOTOR BEARINGS – Lubricate through the two motor oil
cups according to the lubrication decal. At the time of
installation the motor bearings use approx. 12 drops each.
At re-lubrication intervals fill each motor bearing with
approx. 6-8 drops. More or less frequent re-lubrication
may be required depending on the installation conditions.
NOTE: Over-oiling can cause motor mount deterioration and
may cause spillage onto surrounding surfaces. Deteriorated
motor mounts will lead to misalignment and excessive coupler
wear.
PRIMING AND STARTING
Do not run B&G circulator pumps dry. Before starting, the
pump must be filled with water. Air should be vented from the
system by means of a system air vent or by an alternate method.
1. Remove the screws securing the conduit box cover (wiring
compartment) and lift off the cover. Attach the appropriate
size connector to the hole in the side of the conduit box.
2. Using a minimum size 14 AWG copper electrical wire (refer
to your local code for wiring restrictions), wire the motor to
a 115 volt, 60 hertz, single phase power source.
3. Connect the ground wire to the green screw inside the
conduit box.
NOTE: Single phase motors are protected with inherent over-
heating devices and do not require external overload protection.
NOTE: If a motor with special characteristics is selected, the
electrical rating of the power source must be the same as that
of the motor.
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect and lockout the power before making
electrical connections. Failure to follow these instructions
could result in serious personal injury or death.
