Pressure
To change from 115V to 230V
a. Using a pair of needle nose pliers, pull the
gray wire with the female flag connector
from the “A” terminal spade post. Place it
to the right on the “B” terminal space post.
( Fig. 2a)
b. Pull the red wire with the female flag
connector from the “L2” terminal. Place it to
the left on the “B” terminal space post.
( Fig. 2b)
1. The motor of this pump is dual voltage and can
run on either 115V or 230V. In general, 230V is
more economical to run, and requires a smaller
wire size. 1/2 and 3/4 HP pumps are pre-set in
the factory to run at 115V. ( Fig. 1)
2. For 230V service, change the following wires
on the terminal board:
