INSTALLATION
BEFORE YOU BEGIN
Before uncrating the pump, inspect the crate for damage. A damaged crate indicates possible
internal damage to the dispenser, and the delivering carrier should be notified of possible
concealed damage. It is recommended the original shipping crate be retained for pump reshipment at some later date.
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.
Plan your installation carefully. A pump cannot be expected to work satisfactorily unless the
underground 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 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/dispenser installed by a competent installer/electrician.
4. DO install breakaway coupling on discharge hose. If using a high hose retriever, 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 install any underground piping without proper swing joints. (Always use shoulder
nipples, never close nipples).
8. DO NOT cover any lines until they have been both air- and liquid-tested.
9. DO NOT back-fill the tank or supply line with cinders or ashes. (Back-fill with clean sand,
crushed rock, or pea gravel).
10. DO NOT use black iron pipe or fittings for underground installations. (Use only new
galvanized or fiberglass* pipe and fittings). *Install all fiberglass pipe and fittings according to
manufacturer’s specifications and requirements.
03/07/03 2-1
GASBOY 552A/553A Commercial Pumps
11. DO NOT use power line wiring of inadequate capacity. (Use gauge specified by the wiring
diagram or wire chart provided in Section 3).
12. DO NOT use a circuit breaker of improper size. (See Section 3).
13. DO NOT install fill pipe to tank where it can be submerged with standing water.
14. DO NOT use the GASBOY fuel dispensing equipment to remove water ballast from the
storage tank.
15. 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
free of dirt, nicks, and scratches.
16. DO NOT use knock-out boxes or flexible conduit for installing this unit. All wires should be
run in threaded, rigid, metal conduit. All threaded connections must be drawn up tight with
five (5) threads minimum engagement. Only one opening in the AC junction box is provided
with a plug at the factory. At completion of the installation, it is the installer’s responsibility to
ensure that any unused openings are plugged.
Tighten junction box covers before replacing panels.

FOUNDATION
When constructing the pump island for the dispensing equipment, be sure to extend the island
excavation beyond the depth of the frost line. Leave open an area from the inside edge of the
unit’s base as shown on the specific base layout. Unless required by local regulations, do not
cement the pipes and conduits into the island. The open area within the base will provide access
for future servicing of the fittings and conduit assemblies. Fill in the boxed-in section with dry sand
to keep condensation in the pump housing to a minimum and to help prevent fogging of the
totalizer window.
Secure the pump/dispenser to the island using anchor bolts through the two mounting holes,
which are indicated on each base layout by an X. If the dispensing unit is not securely fastened to
the island, supply line leaks at unions and pipe joints may occur. Use one of two types of bolts to
anchor the pump to the island. Use two (2) 1/2" x 5" (13mm x 125mm) long machine bolts
imbedded in the concrete, or, to meet minimum UL and API requirements for universal
interchangeability of pumps, use two 1/2" x 3 1/2" (13mm x 90mm) long lag screws with 2" (51mm)
long expansion shields.
The drawing on the following page, Installation Layout, illustrates a recommended installation of
the Model 552A & 553A power pump. In selecting a location for the pump and tank, bear in mind
that a suction pump will draw liquid horizontally up to 100 feet, but on a vertical lift it is not
advisable to exceed 12 feet (3.6m) for gasoline, or 13 feet (4m) for diesel.
SUCTION PUMP
The pump and the tank should be located close to each other with as few changes in direction of
the supply line, as possible. This reduces the possibility of vaporization (gasoline only), attains the
highest possible flow rate, and results in a lower installation cost. Avoid long supply lines and
excessive vertical lifts. The dynamic lift for this unit is rated at 12 feet (3.6m) for gasoline and 13
feet (4m) for diesel and can vary according to conditions of the installation and fuel temperature.

SUPPLY LINE
Always start at the pump and work toward the tank. Use new galvanized or fiberglass (see note)
pipe, 1-1/2" minimum diameter. (NOTE: Fiberglass pipe is to be installed according to manufacturer’s specifications and requirements.)
Be sure both the pipe and the tank are clean. Foreign matter entering the pump can cause
extensive damage. Obstructions in the supply line can create pump problems and reduced flow
rate.
Make sure all pipe threads ar e proper ly cut and the inside r eamed to remove bur r s. Use UL-listed
gasoline-resistant compound on all joints of gasoline handling piping. Sealing compound must
also be resistant to Gasohol (Ethanol and Methanol). Do not use Teflon Pipe Sealing Tape. Use
gasoline-resistant pipe compound on male threads only; pipe compound used on female threads
can be squeezed into the supply line where it can enter the product stream and become lodged in
the pump or meter. Install swing joints under the pump and at the tank to avoid breaks in the
supply line from settling or frost heave.
To avoid product delivery problems on suction pumps, be sure there are no traps in the supply
line. Supply lines, for both suction pumps and submersible pumps, should go straight down
beneath the pump to a point 18 inches (46cm) below the ground level and pitch at a rate of 1/8
inch per foot (1cm/m) from there down to the storage tank. The supply line should be as short and
direct as possible with swing joints (two 90
the horizontal run of pipe at 10-foot (305cm) intervals to maintain pitch and prevent traps. Do not
use wood as pipe supports.
New EPA regulations require that only one check valve be used per supply line and located
directly below, and as close as practical to the suction pump. Do not use spring-loaded or union
check valves since these will unnecessarily reduce the flow rate and contribute to the reduction of
atmospheric pressure necessary to keep gasoline in a liquid state.
Upon completion of installation, all liquid-carrying lines must be checked for leaks.
Connecting the Suction Pipe
To connect the suction pipe, remove the tin protector from the flange opening in storage tank.
Assemble suction pipe, double tapped bushing and foot valve with suction screen. Insert into
tank, and tighten in position. Starting at suction nipple at base of pump, take pipe measurements
to union elbow on suction pipe riser at top of tank. Cut pipe, assembly together loosely. If
measurements are correct, uncouple all pipe joints and coat them up with a good grade of
gasoline-resistant sealing compound. If pipe measurements are incorrect, a new pipe must be
cut.
NOTE: Underneath pump, a high grade valve with pressure relief must be used in suction
line.

WIRING
Customers & installers having any questions pertaining to the installation should contact
their GASBOY distributor.
WIRING PRECAUTIONS
The quality of the electrical installation is a major factor in maintaining proper safety levels and
providing trouble-free operation of your pump. To assure a quality installation, follow these rules:
1. All wiring must be installed to 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.
2. Use only threaded, rigid, metal conduit.
3. Use only UL-approved insulated gasoline- and oil-resistant stranded copper wiring of the
proper size.
4. Wire connections should be tightly spliced and secured with a wire nut; close off the open end
of the wire nut with electrical tape.
5. The line to the motor should be on a separate circuit and installed on a 20 to 30 AMP breaker
depending on the motor size and/or the voltage setting.
6. 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 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.
WARNING:
To reduce the risk of electrical shock when servicing, turn off and lock out
all power to the pump.
7. Have the pump installed by a competent installer/electrician.
GROUNDING
To ensure proper operation of the equipment and provide the necessary safety factors, this unit
must be grounded. A ground wire (preferably green) must be connected between the unit’s AC
junction box ground lug and the main electrical service panel. One (1) ear th 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).
03/07/03 3-1
GASBOY 552A/553A Commercial Pumps
CIRCUIT BREAKERS
Power to the unit must be supplied from a dedicated 20 to 30 amp breaker. No other equipment
should be powered from this breaker. A tag on the motor identifies the maximum curr ent draw of
the motor. If two units are supplied from one breaker, that breaker must be capable of handling
the load of both motors.
PUMP MOTOR
Pumps are shipped from the factory with motors wired according to the specifications given on the
order as to kind of current, frequency and voltage.
Very often on installation, it becomes necessary to change the original setting to suit the AC power
source. To do this, locate the motor change-over plate (typically located on the shaft end of the
motor) and remove the screw which secures it in place. Slide the plate so that the desired
voltage, as marked on the plate, lines up with the screw hole. Reinsert the screw and secur e the
plate in place. 380 VAC pumps are permanently set and cannot be changed.
Many motor failures result from improper setting of the motor change-over plate. If set for 120
VAC and a 240 VAC feed is used, the motor will burn out after running only a short time. If set for
240 VAC and a 120 VAC feed is used, the motor will run very slowly and the starting field will soon
burn out.
WIRING AND CONDUIT
Pump Wiring
The table below shows the required AC wire size based on the HP rating of the pump motor and
the distance from the circuit breaker to the pump for both 115 and 230 volt units. Use this table as
a guide for selecting the proper size wire for your installation. Consult local wiring requirements
for wiring of 380 VAC motors.
If multiple units are powered from the same breaker through the same wires, you must increase
the gauge of the wires to handle the added load according to the distance from the breaker panel
and the HP rating (if applicable).

Pulser Wiring
Pulser wiring must be 18AWG. If it is run in the same conduit as the AC wiring, it must also
conform to the following wiring requirements:
• Wire must be 2-wire twisted-pair Belden 88760 (C08850) or 4-wire Belden 89418 or
equivalent (C08864).
Both types of cable provide superior noise immunity and are rated as follows:
Belden 88760
Gas and oil resistant insulation & jacket
18 AWG tinned, stranded, copper
One twisted pair (two conductors)
300 volt maximum operating voltage
Aluminum/Mylar shielded w/drain wire
NOTE: If using 88760 cable with a 3-wire pulser, you must run two lengths of cable to
attain two twisted pairs (four conductors). Cap off the unused wire.
Belden 89418:
Gas and oil resistant insulation & jacket
18 AWG tinned, stranded, copper
Stranded, four conductors
300 volt maximum operating voltage
Aluminum/Mylar shielded w/drain wire
• Cable connections to pulser must be made in DC junction box. Pulser cables will pass
through AC junction box.
• Cable drain wire must be connected to the grounding screw in the DC junction box in the
pump/dispenser. The drain wire is not connected at the fuel management system end.
• Rigid metal conduit must be used to connect the AC and DC junction boxes.
Conduit
All wiring to the Gasboy 550A Series dispensing unit must be installed in threaded, rigid, metal
conduit. PVC is not acceptable. It is recommended that DC pulser wiring be run in separate
conduit from any AC wiring; however, it is acceptable to run DC pulser wiring in the same conduit
as AC wiring as long as the requirements outlined in Pulser Wiring are met.
All wiring and conduit runs must also conform with the National Electrical Code (NFPA 70) and the
Automotive and Marine Service Station Code (NFPA 30A). All wiring and conduit runs must
conform to local codes. Canadian users must also comply with the Canadian Electrical Code.
The table that follows shows conduit capacity for rigid, metal conduit with a 50% fill of gas- and
oil-resistant wire. Use this chart as a guideline to determine the proper conduit sizes for the
Gasboy 550A Series dispensing units. When planning the orientation of the wiring runs, follow the
applicable wiring diagram and consider the layout of the components at the site. Long runs or a
large number of bends may require you to increase conduit size over what is listed.
03/07/03 3-3
GASBOY 552A/553A Commercial Pumps
Conduit Size
To connect the rigid conduit for the motor, start at the electrical connection box in pedestal of
pump, and take necessary measurements for pipe between motor and switchboard in building.
The conduit must be connected to make it water-and vapor-tight. Do not use flexible conduit.
When pulling wires through conduits, be careful not to damage insulation or break wires. To
connect wires, ends of wires must have insulation removed. Splice them tightly together, apply
solder, and follow with an application of electrical tape equal in thickness to insulation of wire
leads.
WIRING NOTES
1. All wiring and conduit runs 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.
2. The brown wire (Switch Detect) is shipped capped from the factory. When used, it connects
to a solenoid valve or fuel management system. Do not connect this wire without first
checking the ON voltage of this line to ascertain compatibility with the equipment being
connected.

MAINTENANCE AND TROUBLESHOOTING
GENERAL
GASBOY pumps are designed and constructed to give many years of uninterrupted service. In
fact, hundreds of operators report years of trouble-free operation with absolutely no service
expense. Yet, certain parts of a pump are bound to wear, and GASBOY therefore recommends a
periodic inspection, at least twice a year, for such things as fuel leaks, belt tension and condition,
lubrication and strainer cleanliness. If such a procedure is followed, any small adjustments that
are necessary can be made before expensive, annoying breakdowns occur. The result of this
sound approach is continuous, profitable service from all of your GASBOY equipment.
Procedures requiring disassembly of portions of the pump should be performed by
qualified service personnel.
WARNING:
To reduce the risk of electrical shock when servicing, turn off and lock out all
power to the pump. Always turn off and lock out all power to the pump at the
master panel before performing any maintenance or service, including the
changing of any fuel filters or strainers. Also block islands so no vehicles can pull
up to the pump while it is being worked on.
Where to Get Help: If your pump should stop or fail to operate properly, GASBOY has a
distributor network which services fuel dispensing and management systems in every section of
the country.
Use Authorized Parts: Parts needing replacement should be replaced only with GASBOY new
authorized service parts. This will ensur e the best results and the continuity of the Underwriters’
Label on your pump. Incorrect or substandard parts can result in unsatisfactory pump operation.
Always use new gaskets or seals when servicing or rebuilding GASBOY equipment; do not re-use
old ones.
EXTERIOR MAINTENANCE
The urethane finish on GASBOY pump housings is similar to that used on automobiles. Keep
your pump looking like new by thoroughly cleaning its exterior with a high grade automobile polish
and then protecting it with a coat of paste wax. Do not use abrasive cleaners or polish. Do not
use high pressure spraying equipment.
03/07/03 5-1
GASBOY 552A/553A Commercial Pumps
LUBRICATING THE PUMP’S COMPONENTS
The following illustration shows the lubrication locations for your 550A Series pump.
Linkage Apply one drop of oil (SAE 10) at each pivot point of linkage every six months.
Register Every six months, or after each 100,000 gallons delivered, clean the register with
compressed air, and wipe all accessible parts (such as figure wheels) with a clean cloth. Use a
light, non-acid type oil (SAE 10), applying one drop between each figure wheel. Never use
solvents such as gasoline or kerosene, as they can become trapped in many of the inaccessible
bearings and dissolve the new lubricant when applied.
Motor Every three months, the oil the motor with 3 drops of high grade light oil (SAE 10) . Avoid
over-lubrication; more motors are damaged by too much, rather than too little, oil.
Rotary Pump & Air Separator Assembly O nce every six months, lubricate the felt with 1 oz. of
high grade light oil (SAE 10).
Meter Do not disassemble the meter for lubrication.
Gear Train Do not lubricate the gear train. It is permanently lubricated at the time of
manufacture.
5-2 03/07/03
Maintenance and Troubleshooting
CLEANING THE STRAINER
Once every three months, remove strainer cap using the correct wrench and turning in
counterclockwise direction. Remove the strainer screen and clean it with compr essed air or by
rinsing in solvent.
NOTE: Always wear protective safety goggles or glasses when using compressed air.
Replace the gasket after cleaning the strainer screen and before reinstalling strainer cap. Be sure
strainer cap is drawn up tight after reinstalling, as a leak will prevent proper operation of pump.
CALIBRATING THE METER
All GASBOY pumps and dispensers are adjusted for accurate measure at the factor y. However,
since the conditions of the installation can affect pump accuracy, it is the responsibility of the
installer to check the pump for accuracy and make any needed adjustments. Where required, it is
the owner’s responsibility to report this device to the local Weights and Measures officials for their
inspection before the unit is put into service. Calibration methods are given in gallons. When
calibrating liter pumps, use the same procedure, but convert gallons to liters (1 gallon = 3.78
liters).
The adjustment of measurement is
accomplished by breaking the seal wire and
removing the Seal Pin. This will permit the
Index Disc, to be turned either
counterclockwise (-), decreasing the
measurement, or clockwise (+), increasing the
measurement. A variation of approximately
one cubic inch in measurement is obtained by
turning the Index Disc five holes. After
measurement has been properly adjusted, the
Seal Pin and seal wire should be replaced.
CORRECTING METER DRIVE SHAFT LEAK
If a leak develops around the meter drive shaft, it can be corrected as follows:
1. Remove screws and lockwashers securing gear train assembly and remove gear train
assembly.
2. Remove following items by lifting from meter cover packing cavity: upper bearing assembly,
washer, seal, o-ring, seal retaining ring, seal, o-ring, and seal retaining ring.
3. Reseal meter drive shaft by using the following new parts: seal, o-ring, seal retaining ring,
seal, o-ring, and seal retaining ring.
NOTE: Seals are to be formed to meter shaft size by rotating seals on a smooth 3/8" dia.

ADJUSTING THE BELTS
A loose belt reduces pump output due to slippage, and results in excessive wear. Once every six
months, check for proper V-belt tension. V- belt tension is proper when the back side of the belt
can be depressed approximately 3/8" (9.5mm). If adjustment is required, loosen cap screws and
pivot idler arm either upward or downward to obtain proper tension. Cap screws must be retightened before belt tension can be checked.

Maintenance and Troubleshooting
TROUBLESHOOTING
Possible Cause Checks Corrective Action
Failure of bypass valve causes
pump to stall completely
Failure of regulating valve to
open prevents gasoline from
flowing to meter.
Failure of regulating valve to
close.
Failure of float needle valve to
open causes gasoline to be
discharged from air vent tube.
Presence of foreign material in
pump may cause bypass valve
to become stuck in its seat or
valve cylinder. Condition may
develop when a pump has
been idle for some time; when
water is present; or when ice
has formed.
Foreign matter may be lodged
in valve cylinder.
Insufficient pressure in supply
chamber due to break in
suction pipe, empty
underground storage tank,
clogged strainer screen, stuck
foot valve, needle valve,
extreme wear of parts or
excessive end play in rotary
pump head assembly, or ice
formation during cold weather,
if water is present in gasoline.
Valve may be held off its seat
by small particles of foreign
matter. Effect on normal pump
operation is not noticeable;
however, when the pump is
standing idle, even a slight
leak will permit gasoline to
drop down in the system.
May be caused by float being
clogged with gasoline, or by
corrosion of small pins (float
lever and valve pin) of needle
valve mechanism.
Float may be filled with product
caused by leak or puncture in
float.
Remove by-pass valve, clean
all parts, and reinstall the
valve.
Clean all parts and reinstall
valve.
Check list of possible causes
and perform appropriate
remedy.
Remove regulating valve and
clean dirt from poppet and
seat; reinstall.
If cork disc of regulating valve
is badly pitted or worn, replace
it with a new regulating valve.
Replace a damaged float with
a new one. Clean or replace
corroded parts.
Replace with new float
assembly.

PREPARING USED PUMPS FOR STORAGE
Special care should be taken when pumps are removed from service prior to storage. Gasoline,
moisture, and foreign material that is left in the pumps will do extensive damage to the internal
working parts. This damage can be prevented, if entire pump is drained of gasoline, moisture, and
foreign material before it is put into storage.
1. Remove drain plugs in r otary pump and separator body and in the top of meter cover. Then
lay pump on its side and elevate bottom of pump.
2. Apply compressed air (no gr eater that 50 pounds [3.5barr]) through suction inlet to force out
all gasoline, moisture, and foreign material that may be trapped in the inaccessible cavities.
Be sure to wear safety glasses when using compressed air.
3. Oil interior working parts by using a spray gun filled with light oil (free from gum content). The
oil may be blown in through the suction inlet.
4. Shellac drain plugs and reinstate them in their pr oper positions. Use a cloth bag or wooden
plug to cover the suction inlet and discharge outlet to prevent dirt from entering interior.

PARTS LIST
GENERAL
This section lists parts information for the 550A Series pumps. Using part numbers when order ing
will expedite your order and reduce the possibility of the wrong parts being shipped.
Procedures requiring disassembly of portions of the pump should be performed by competent
service personnel. Do not depend upon the repair service of a general mechanic unless he is
thoroughly familiar with the mechanism. GASBOY has a distributor network which services fuel
dispensing and management systems in every section of the country.
WARNING:
To reduce the risk of electrical shock when servicing, turn off and lock out all power to the pump.
Always turn off and lock out all power to the pumps at the master panel before performing
maintenance or service, including the changing of any fuel filters or strainers. Also block islands
so no vehicles can pull up to the pump while it is being worked on.
