SAFETY
INSTRUCTION

This safety alert symbol will be used in this manual and on the
pump safety instruction decal to draw attention to safety related
instructions. When used, the safety alert symbol means ATTEN­TION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
FAILURE TO FOLLOW THE INSTRUCTION MAY RESULT IN
A SAFETY HAZARD.

Your Little Red Booster Pump should have the warning label
displayed to the right (Fig. 2) affixed to the motor housing and
the warnings and cautions displayed at right (Fig. 3) clearly
marked in raised letters on the motor end covers. If any of
these warnings and cautions are missing or illegible, contact
your local Bell & Gossett Representative for a replacement.

ADDITIONAL SAFETY REQUIREMENTS

1. Electrical connections to be made by qualified electrician in
accordance with all national, state and local codes.

2. Adequate electrical grounding is required for the safe oper­ation of the Little Red Booster Pump, and the use of grounded
metal conduit assures this requirement. If the means of con­nection to the supply-connection box (wiring compartment)
is other than grounded metal conduit, ground the pump
back to the service by connecting a copper conductor, at
least the size of the circuit conductors supplying the pump,
to the green grounding screw provided within the wiring
compartment.

Replace conduit box cover and secure with screws.

3. The maximum working pressure of the pump is listed on
the pump nameplate, do not exceed this pressure.

4. This pump is for indoor use only.

The motor housing cover is a functional component designed
to prevent accidental contact with the motor fan. Do not re­move this cover unless power to the pump is disconnected
and locked out.

1. Close the valves on the suction and discharge sides of the
pump. (If no valves have been installed, it may be neces­sary to drain the system.)

2. Remove the conduit box cover by removing the two screws
at the top of the cover.

3. Disconnect the electrical supply lines to the pump.

4. Remove the four flange nuts and bolts and remove the
pump from the piping.

WARNING: Before installing, using or servicing this

product. Read the warning notes and instructions in
instruction manual. Failure to do so may result in injury or
property damage.

WARNING: Rotating Component Hazard

Do not operate pump without all guards in place.
Failure to follow these instructions could result in serious
personal injury or death, and property damage.

WARNING: Excessive Pressure Hazard

WARNING: Volumetric Expansion

The heating of water and other fluids causes volumetric
expansion. The associated forces may cause failure of the
system components and release of high temperature fluids.
This will be prevented by installing properly sized and lo­cated compression tanks and pressure relief valves. Failure
to follow these instructions could result in serious personal
injury or death, and property damage.

REMOVAL OF PUMP FROM EXISTING SYSTEM FOR REPLACEMENT

WARNING: Electrical Shock Hazard

Disconnect and lockout the power before servicing.
Failure to follow these instructions could result in serious
personal injury or death.

WARNING: Hot Water Hazard

Before draining the system, allow water to cool at
least 100°F (38°C), open the drain valve (take precautions
against water damage) and leave the drain valve open until
servicing is complete. Failure to follow these instructions
could result in serious personal injury, death and/or
property damage.

WARNING: Hot Water Hazard

Whenever disassembling a gasket joint, always use
a new gasket upon reassembly. NEVER RE-USE OLD
GASKETS. Failure to follow these instructions could result
in serious personal injury, death and/or property damage.

WARNING: Unexpected Start-Up Hazard

Single phase motors are equipped with automatic
reset overload protectors. The pump can restart without
warning. Disconnect and lockout power before servicing.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.

CAUTION: Temperature Hazard

Check surfaces for high temperatures, allow the
pump temperature to reach approximately 100°F (38°C),
before proceeding. Failure to follow these instructions
could result in moderate personal injury and/or property
damage.

WARNING: High Pressure Hazard

Pressure may be present in the pump body. This
pressure can be relieved by loosening the flange bolts and
shifting the pump assembly slightly to allow the pressur­ized water to escape. Failure to follow these instructions
could result in serious personal injury or death.
