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!
Plumbing Installation
1. When connecting pipework to pump with threaded ports, it is recommended that thread seal tape be used. Hard-plumbed
pipes must have proper solvent-weld connections. Flexible hose connections must be tightened properly. If the suction line
is not sealed correctly, the pump will not prime properly and will pump small volumes of water or none at all.
2. When installing the pump, care should be taken to see the suction line is below water level to a point immediately beneath
the pump to ensure quick priming via a flooded suction line. The height between the pump and water level should not be
more than five (5) feet.
NOTE: The E71-II VHV is NOT self-priming and must be installed below water level.
3. Suction and discharge lines should be independently supported at a point near the pump to avoid strains being placed on
the pump. Always use properly sized valves.
4. When installing the pump below water level, it is advisable to install a gate valve in both the suction and discharge line in
the event that the pump must be removed for servicing.
5. Before starting the pump for the first time, remove the see-through lid. (Turn lid ring counter-clockwise to remove.) Fill
strainer tank with water until it is level with the suction inlet. Replace lid with locking ring. Hand-tighten the lid to make an
air-tight seal.
DO NOT
use any tools to tighten the lid.
6. Use the fewest number of 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.
Electrical Installation
1. The pump motor must be securely grounded inside the motor control box. (See Figure 2)
NOTE: DO NOT connect to electric power supply until unit is permanently grounded.
2. Wire size must be adequate to minimize voltage drop during the start-up and operation of the pump. See Table 1.0 for
recommended wiring sizes.
