Making Electrical Conections:
All electrical wiring must be in
accordance with local code, and
only competent electricians
should make the installations. A
set of prints is included for use in
making the installation. All wires
should be checked for grounds
with an ohmmeter or Megger
after the connections are made.
This is important, as one
grounded wire can cause
considerable trouble.
See Fig. 1.

Heat Sensors and Seal Failure
Connections:
Be sure that heat sensor wires are
connected in series with
the starter coil. Connections are
provided on the terminal strip; see
wiring diagram.
If seal failure unit is used,
connect as shown with seal
failure system. If seal failure unit
is not used, the two seal failure
wires are left open.
Do not
connect power to these lines at
any time.
See Figs. 2 and 3.
