Section 8. Twelve (12) Volt Installation
A separate 12-Volt AC Transformer is required on all 12-Volt Models--For
Jandy Pool Light
use a 300-watt
multi tap 12-volt system. For the
Jandy Spa Light
, a 100 watt 12-volt system is acceptable. To ensure
maximum safety, it is strongly recommended that a transformer that has been listed or recognized by a
Nationally Recognized Testing Laboratory (NRTL) for the application be used.
NOTE
Jandy does not recommend installing 12-volt lights with cord lengths greater than 50 feet. A significant
voltage drop will occur that dramatically reduces the light output and possibly unit failure. Wires from
Transformer to Junction Box can reduce voltage and brilliance in addition to losses in the12 gauge 12-volt
cord. Refer to chart below for wire voltage losses and potential effect.
