Step 6:
Close the ball valve
(Item 6)
. The handle
should be perpendicular to the valve body
(Photo 14)
.
Step 7:
Find the solenoid valves on the control
panel wiring schematic. Typically they are
on page 2 and labeled SV1 and SV2. Look
to see if you have delay timers located on
the schematic right before the solenoids
(typically labeled TD1/TC and TD2/TC).
There are three different options for the
solenoid valve and delay timers and they
are:
Option 1
- Solenoid valve is mounted to
the control panel and there is already a
delay timer on the solenoid valve (most
stations before 2002).
(see Diagram 1)
If
you have this option, go to step 8.
Option 2
- Solenoid valve is mounted to
the control panel and there is no delay
timer on the solenoid valve (most stations
from 2002-2008)
(see Diagram 2)
. If you
have this option, go to step 9.
Option 3
- Solenoid valve is mounted off
the vacuum pump and there is no delay
timer on the solenoid valve (usually on
FX stations or pump stations recently
upgraded to the larger ported solenoid
valve with kit H87A343A)
(see Diagram
3)
. If you have this option, go to step 10.

DANGER:
Disconnect and lock
out power before performing any
electrical work. Failure to do so
could result in electrical shock, serious
bodily injury or death.
WARNING:
All electrical work
should be performed by a
qualified electrician and per all
applicable codes. Failure to do so may
result in severe bodily injury or death.
