The system must be built so that it cannot operate with the pump drawing
water from only
one main drain (that is, there must be at least two main drains
connected to the pump whenever it is running). However, if two main drains
run into a single suction line, the single suction line may be equipped with a
valve which will shutoff
both main drains from the pump.
More than one pump can be connected to a single suction line as long as the
requirements above are met.
Water Velocity
The maximum water velocity through any suction outlet must be 1.5 feet per
second unless the outlet complies with the latest ASME/SNSI Specification for
Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications. In any case, do not exceed the suction fittings maxi-
mum designed flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum
water velocity in the pump suction hydraulic system must be six feet per sec-
ond or less even if one main drain (suction fitting) is completely blocked. The
flow through the remaining main drain(s) must comply with the latest
ASME/ANSI Specification for
Suction Fittings For Use in Swimming Pools,
Spas, Hot Tubs, and Whirlpool Bathtub Applications.
ELECTRICAL
Ground motor before connecting to electrical power supply. Failure to
ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF power to motor
before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical
problem. If GFCI trips and will not reset, have a qualified electrician
inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage. Incorrect voltage
can cause fire or seriously damage motor and voids warranty.
If in doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and re-
duced component life. If voltage is less than 90% or more than 110% of rated
voltage when motor is running at full load, consult power company.
Hazardous voltage.
Can shock, burn,
or cause death.
Ground pump before
connecting to
power supply.
