1.2.2 Special Notices
NOTICE
The state of California requires that all residential in-ground pool pumps
rated greater than 1HP have at least two-speeds. The low speed
must be the default circulation speed. The high speed operates only
temporarily or intermittently. This speed variation reduces the pump’s
electrical consumption by calculating its volume, pressure, and power
based on the change in revolutions per minute (rpm) or the change in
the impeller diameter.
The 2Green meets all California legal requirements.
NOTICE
When using two-speed pumps manufactured on or after January 1,
2008, the pump’s default circulation speed MUST be set to the LOWEST SPEED. A high speed override can be set for a temporary period
not to exceed one normal cycle, or two hours, whichever is less.
California Title 20 Compliance for Pool Pumps
The built-in electronics control only one line input to the motor. The
system power must be disconnected prior to installing/servicing to avoid
the risk of electrical shock. Failure to do so can result in electrocution or
personal injury such as shock or burns, or damage to the equipment.

•
The High Speed mode duration or Low Speed mode duration is set in increments of 30 minutes.

operation after the Manual mode operation ends. The motor can operate in either High Speed manual or Low Speed manual for a maximum
of 24 hours.
Only one mode can be activated at a time. Select the time period for
which the motor operates in either High Speed manual or Low Speed
