Review the field piping diagrams and wiring diagrams before you install and operate the
unit.
Electrical precautions
WARNING:
Electrical shock hazard. The electrical supply must match the control panel nameplate
specification. Incorrect voltage can cause a fire, which damages the electrical components
and voids the warranty. Failure to follow these instructions could result in serious personal
injury or death, or property damage.
WARNING:
Overheating hazard. Aluminum wiring SHALL NOT be used for any part of this packaged
system.
NOTICE:
Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
Power wiring
Select power wire types and sizes based upon conformance with the National Electrical
Code and all local codes and restrictions. In addition, only copper (Cu) wire rated for at
least 167°F (75°C) can be used for the power connections. Refer to the input current as
listed on the motor nameplate when sizing wire.
Power supply requirements
The power supply required for the AquaBoost unit depends on its model number. It can
be one of the following with a dedicated ground wire:
• 230/1/60
• 208-230V, 230, 460, 575/3/60
• 380/3/50
WARNING:
Electrical shock hazard. Conduit grounds are not adequate. You must attach a separate
ground (earth) wire to the ground (earth) lug provided in the enclosure in order to avoid
potential safety hazards. Failure to follow these instructions can result in serious personal
injury, death, or property damage.
Input voltage tolerance
The input voltage tolerance is ±10% of the voltage indicated on the nameplate.
Overload protection for variable-speed units
Variable-speed units have a single-point power panel with fuses for protection against
voltage spikes. In addition, the controllers have inherent features that protect the unit
against:
• short circuit
• undervoltage
• overload
• motor temperature
• dead heading
