Bonding And Grounding - Speck pumps Badu EcoM3V Installation, Operating And Service Manual

Plumbing Installation - continued
If the pump is located below water level, isolation valves must be installed on both sides of the pump to
prevent the back flow of pool water during any routine or required servicing. The Badu EcoM3 - Variable
Speed comes equipped with unions on both the suction and discharge ports. This feature simplifies
installation and service and eliminates the possibility of leaks at the threaded adaptors.
Before starting the pump for the first time, remove the see-through lid. (Turn lid counter clockwise to
remove.) Fill strainer tank with water until it is level with the suction inlet. Replace lid, making sure the
o-ring is not damaged. Screw down, hand tight.
Suction and discharge line should be independently supported at a point near the pump to avoid strains
being placed on the pump. Always use properly sized valves.
Use the fewest fittings as possible. Each additional fitting has the effect of moving the equipment farther
away from the water.
NOTE: If more than ten (10) suction fittings are needed, the pipe size must be increased.
Every new installation must be pressure tested according to local codes. See the Pressure Testing
Section on page 7

Bonding and Grounding

When installing and using the motor, basic safety precautions should always be followed. The wiring of
the motor should be done by a licensed electrician in accordance with local codes.
BONDING AND GROUNDING
1. The motor frame must be grounded to a reliable grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or larger must be used. If the pump is installed within five
(5) feet of the inside walls of the swimming pool, spa, or hot tub, the motor frame must be bonded to
all metal parts of the swimming pool, spa, or hot tub structure and to all electrical equipment, metal
conduit, and metal piping within five (5) feet of the inside walls of the swimming pool, spa, or hot tub.
2. Bond the motor using the provided external lug.
WARNING: Always disconnect the power source before working on a motor or its connected
load.
WARNING: In order to avoid the risk of property damage, severe personal injury, and/or death,
make sure that the control switch, time clock, or control system is installed in an accessible
location, so that in the event of an equipment failure or loose plumbing fitting, the equipment
can be easily turned off.
CAUTION: The pump must be permanently connected to a dedicated electrical circuit. No
other equipment, lights, appliances, or outlets may be connected to the pump circuit, with the
exception of devices that may be required to operate simultaneously with the pump, such as a
chlorinating device or heater.
WARNING: Motor is fitted with internal auto reset. May restart without warning!
