2. Installation
Installation Precautions
All installations must conform with all building/fire codes, all Federal, State, and Local codes,
National Electrical Code, (NFPA 70), NFPA 30, and Automotive and Marine Service Station Code
(NFPA 30A) codes and regulations. Canadian users must also comply with the Canadian
Electrical Code.
Plan your installation carefully. A pump cannot be expected to work satisfactorily unless the
installation is correct. Dispensing troubles, which seem to be pump-related, are frequently traced
to faulty installation. Review the following list of installation DO's and DON'T's to avoid
potential problems:
1. DO read the WARNINGS page at the front of this manual, preceding the Table of Contents.
It contains important information regarding the safe use of your dispensing equipment.
2. DO install an emergency power cutoff. In addition to circuit breaker requirements of NFPA
70 and NFPA 30A, a single control which simultaneously removes AC power from all site
dispensing equipment is recommended. This control must be readily accessible, clearly
labeled, and in accordance with all local codes.
In a fuel management system application, the EMERGENCY STOP and STOP keys on the
console and/or the optional EMERGENCY STOP button on the Island Card Reader do not
remove AC power from equipment and under certain conditions, will not stop product flow.
In order to provide the highest level of safety to you, your employees, and customers, we
recommend that all employees be trained as to the location and procedure for turning off
power to the entire system.
3. DO have the pump installed by a competent installer/electrician.
4. DO install breakaway coupling on discharge hose. If using a high hose retriver, install
breakaway approximately 12" downstream of hose clamp on nozzle side of clamp.
5. DO NOT experiment with a pump if you are not sure the installation is correct.
6. DO NOT overload sub- or main breaker panels.
7. DO NOT use power line wiring of inadequate capacity. (Use gauge specified by the wiring
diagram or wire chart provided in Section 4).
8. DO NOT use a circuit breaker of improper size. (See Section 4).
9. DO NOT use the GASBOY fuel dispensing equipment to remove water ballast from the
storage tank.
10. DO NOT use gaskets on covers of explosion-proof type boxes. The sealing compound found
around wires at various locations within conduit is a requirement of the National Electrical
Code and should not be disturbed. Ensure that the mating surfaces between the junction box
and cover are free of dirt, debris, nicks and scratches. Tighten junction box covers before
replacing panels.
11. DO NOT use knock-out boxes or flexible conduit for installing this unit. All power wires
should be run in threaded, rigid, metal conduit. All threaded connections must be drawn up
tight. All but one opening in the power junction box are provided with plugs at the factory.
At completion of the installation, it is the installer's responsibility to ensure that any unused
openings are plugged.

GASBOY Series 9820Q

Vent Line
The vent line for standard units is vented to the atmosphere. Whenever possible, it is
recommended that the line be returned to the tank. A hole is provided above the normal vent
opening to allow this line to exit the pumping unit and return to the tank.
Vapor Recovery Option
This dispenser can be supplied with components necessary to provide vapor recovery. If the
dispenser is equipped for vapor recovery, a splitter is located in the pump housing. A 3/4"
discharge line will exit from the rear of the pump housing to return vapor/fluid to the tank. No
changes are required to the nozzle hook or boot assembly when using vapor recovery nozzles.
Please note that the vapor recovery nozzles approved for use are the "short spout" type. The
following nozzles and hose are approved for use with vapor recovery systems:
Nozzles: Emco Wheaton Model A4015
Husky Corp. Model 5010
OPW Model 211V
Hose: UL-Listed Hose Assembly
Hose Length Estimator
Use the chart on the next page to estimate the length of hose needed for your 9820Q application.
The correct length will prevent the hose from touching the ground when the nozzle is placed into
the nozzle boot/hook arrangement of the register. This chart assumes that the 9820Q register is
mounted on the standard pedestal and that the bottom of the pedestal is mounted flush with the
bottom of the tank. The illustration below provides a visual reference for the chart.

Height Measurement from the ground to the hose connection assuming the pumping unit is mounted
on top of the tank with the feet provided.
Tank height + 6" , standard units; tank height + 12" for vapor recovery units.
Hose Length Length of hose less nozzles and fittings.
Register Minimum Radius Indicates the closest the register assembly can be to the specified starting point; any closer
than this distance may allow hose to touch the ground when unit is not in use. This radius is
measured starting from a point directly below pumping unit discharge to the center of the
nozzle boot/hook of the register assembly.
Fueling Radius Indicates the approximate fueling radius. Measured from a point directly below pumping unit
discharge to the nozzle.

3. Control Lines
PurposeThis section is provided to familiarize the installer with the control inputs and outputs that are
available for the Series 9820Q. It is recommended the installer read these descriptions to obtain a
better working knowledge of the unit in order to guide him in planning the site wiring. Reference
Section 4 for a specific wiring diagram and installation notes.
The Series 9820Q may be provided for use with 230 VAC power for international applications.
The operating voltage for control lines to these units is shown in parentheses as (230 VAC Int'l).
If connecting the 9820Q to a GASBOY fuel management system, refer to the appropriate fuel
management system Installation Manual for detailed installation information.
Ground To ensure proper operation of the equipment and provide the necessary safety factors, a good
ground line must be provided. A ground wire (preferably green) must be connected between the
ground screw of the register and the main electrical service panel. One (1) earth ground
connection is required per unit. The ground rod is to be a solid, corrosion-resistant conductor and
must be installed at the main electrical panel in accordance with the National Electrical Code. It
should be properly tied into the ground bus strip of the panel. We recommend the neutral and
ground bus strips be bonded together (unless prohibited by local codes).
Micro Feed
The Micro Feed is a 115 VAC (230 VAC Int'l) input required to power the microprocessor of the
register's electronics. This power must always remain on and must be on a separate breaker from
the control lines (Pump Motor Feed). In a site configuration using multiple units, the power for the
microprocessors of up to 8 units can be supplied by one breaker.
Micro Neutral
The Micro Neutral is a return line for AC current from the microprocessor of the dispensing unit to
the breaker panel.
Pump Motor Feed
The Pump Motor Feed is a 115VAC (230 VAC Int'l) input which is required to power the pump
and authorize the control line. This line is used to provide authorization for the unit (when enabled
through the DIP switches). If this line is controlled by a fuel management system using solid state
relays, a resistor assembly must be installed between the Pump Motor Feed line and Feed Neutral
to prevent false triggering of the authorization input. The resistor assembly is 8.2K OHM, 10 Watt
(P/N C05818) for 115/230 VAC domestic and 30K OHM, 10 Watt (P/N C06683) for 230 VAC
international wiring.
The Pump Motor Feed line is used to power the slow flow and fast flow valves (when installed).
The power used to control the pump is also provided by this line. The Reset Complete signal used
for external monitoring of the pump originates from the Pump Motor Feed line.

GASBOY Series 9820Q
14 MDE-4339 9820Q ASTRA Installation/Operation • July 2004
Neutral Feed
The Neutral Feed is the AC current return line back to the breaker panel for all attached devices
(pump motor, solenoid valves).
Slow Flow (Reset Complete/Switch Detect)
The Slow Flow line is a 115VAC (230VAC Int'l) output which is used to control the slow flow
valve of the optional solenoid valve. This line also indicates when the reset process is complete
and the unit is ready to dispense product. This line can be used in conjunction with a fuel
management system (for systems other than the Gasboy CFN Series systems).
This line is capable of supplying 300 mA AC maximum (170 mA maximum if already connected
to the optional valve). This line must not be shorted to any conduit or chassis metal, mis-wired, or
be connected to any equipment requiring more than stated maximum allowable current. If these
restrictions are not followed, damage to the CPU PCB will occur.
Fast Flow
The Fast Flow line is a 115VAC (230VAC Int'l) output which is used to control the fast flow valve
of the optional solenoid valve.
This line is capable of supplying 300 mA AC maximum (170 mA maximum if already connected
to the optional valve). This line must not be shorted to any conduit or chassis metal, mis-wired, or
be connected to any equipment requiring more than stated maximum allowable current. If these
restrictions are not followed, damage to the CPU PCB will occur.
Phase 2 Feed
The Phase 2 Feed is a hot feed which is the opposite phase of the pump motor feed. This line and
the pump motor feed are used for 230VAC motor applications. If connected to equipment
requiring control of the authorization input, the Phase 2 Feed should be switched through a
separate relay to prevent false triggering of the authorization signal.
Pulser These lines are used to connect the pulser, mounted in the pumping unit, to the electronics in the
register assembly. These are DC voltage lines and provide the information necessary for the
register assembly to monitor the quantity of product dispensed. These lines are for internal use
only and must not be used for the pulse output (for external monitoring of the unit). Use the
optional Pulse Output interface if external pulses are required.
Pulse Output
This option provides a DC pulser output to indicate the quantity dispensed. This is an open
collector output. This output can sink up to 150 milliamps DC at voltages up to 24 VDC. The
pulse rate can be configured by a sealable DIP switch for rates of 1, 10, 100, 250, 500, or 1000
pulses per gallon or 1, 10, 100 or 250 pulses per liter. This output should only be used when
monitoring of the unit's operation is desired.
