4.1 ELECTRICAL REQUIREMENTS AND
INFORMATION
Following are general electrical requirements and
information for Aqua Whisper Modular models.
CAUTION
: DO NOT PERFORM
INSTALLATION UNLESS:
1. The System Feed Water Sea Cock Valve
is closed.
2. The system main electrical disconnect switch
is switched “OFF”, LOCKED, and TAGGED.
WARNING
: ELECTRICAL SHOCK
HAZARD. A Volt / Ohm Meter will be
necessary. The following installation
procedures expose the installer to High
Voltage and electrical shock hazard.
Only attempt this if you are a qualified
electrician and only if surrounding
conditions are safe.
CAUTION
: Always allow slack in
electrical cables. Allow the cable to enter
or leave from the strain relief in a straight
manner for several inches to ensure
proper connection, to relieve stress to
the cable and fitting, and to allow ease
of detachment and reattachment for
maintenance or replacement. If electrical
cables are pulled tight causing them to
bend at the strain relief, they will pull out
of the strain relief causing a dangerous
electrical shock condition, the wire may
break, and the strain relief will lose its
water-tight integrity.
A. AMPERAGE NOTES
The Electric Motors within the Aqua Whisper systems
start in series with time delay between each motor
starting after the Touch Screen “Start” Switch is pressed.
First, the Booster Pump starts, then the main High
Pressure Pump Electric Motor starts. Alternatively, the
Booster Pump and High Pressure Pump may be started
manually by accessing the manual operation mode from
the Touch Screen.
During start up, the current of the Booster Pump Electric
Motor surges to “Locked Rotor” amperage for a fraction
of a second after which the current drops to normal
running load. Then the High Pressure Pump Electric
Motor starts and surges to “locked Rotor” amperage for
a fraction of a second after which the current drops to
normal running load.
Therefore, the maximum surge current equals the
Booster Pump Electric Motor normal running amperage
plus the High Pressure Pump Electric Motor starting
amperage. Normal operational amperage equals the
normal operating amperage of the Booster Pump Electric
Motor plus the normal operating amperage of the High
Pressure Pump Electric Motor.
B. POWER SOURCE REQUIREMENTS
Check line voltage and frequency to ensure that it agrees
with system nameplate. Grounding and circuit protection
should be done in accordance with National Electrical
Code. See connection diagram on nameplate of motor or
refer to the diagrams within this manual.

C. MOTOR ROTATION
Refer to Booster Pump and High Pressure Pump
markings to determine proper rotation.
Three Phase Systems: Ensure proper rotation by jogging
each motor from the manual operation mode.
