Pedestal Installation
1. Using the terminal pedestal as a guide, mark
the location of the pedestal mounting holes.
2. Install conduit "B" as required for each dis-
penser. Allow room for at least 6 conductors
FROM each dispenser for control signals
PLUS any conductors needed for accessories
such as lighting or hose reel motors.
3. Install conduit "A" for the low voltage pulser
and ground reel signal wires. Allow for 5 con-
ductors from each dispenser (three for the
pulsers and two for the ground reel sensors).
The ground reels (if this option has been spec-
ified) should be mounted as close to the dis-
pensers as possible. The grounding reel sen-
sor consists of a 1/2" diameter nipple mounted
inside 1" threaded pipe which couples with rigid
conduit (Figure 9).
4. Route a single pair telephone cable to the base
of the pedestal. Direct burial cable is often the
best choice. It may be strapped to the outside
of the conduit.
5. The wiring guide calls for two legs of power (3
wires) from the breaker panel out to the ped-
estal. One circuit powers the terminal head, the
other 110 VAC circuit provides for dispenser
power (power for reset motors, electrically ac-
tuated valves, pulsers, etc.). Pump motors are
powered from separate circuit breakers and
require their own Hot (both L1 & L2 for 220
VAC motors), as well as neutral and ground
wires.
6. At this point in the installation process you
should be able to anchor the terminal pedestal
using 3/8" anchors with either flat washers and
nylon locking nuts or lock washers and stan-
dard hex nuts. It is recommended that stain-
less steel be used for this purpose. If you have
any questions please do not hesitate to call QT
Technologies for assistance.
7. Next, referring to the schematic in Figure 8
make all connections between the pedestal,
dispensers and pump motors. Low voltage sig-
nals are terminated on the small connector to
the right.
8. Once all wires are terminated to the DPI board,
simply turn the AUTO/MANUAL toggle switch
to MANUAL to pump in MANUAL mode. All
that is needed is 120V power feeding the first
terminal of the DPI board.
