using the pump.

DO NOT use near open flame or electrical
equipment which may ignite fumes.

DO NOT permit the dispensing of gasoline
or other petroleum products into a vehicle
with its motor running.

DO NOT permit the dispensing of gasoline
or other petroleum products into
unapproved containers or into approved
containers in or on vehicles including
trucks. All containers must be filled on the
ground to prevent static discharge. Always
use Approved and Listed hoses and nozzles
with electric pumps and dispensers.

DO NOT block open the nozzle in any
manner. Nozzles shall conform to UL and
NFPA code requirements for attended or
unattended service.

DO ensure that the pump is equipped with
proper filters based on the product being
dispensed and its intended use.

clothes when dispensing any liquid which
may be potentially harmful or hazardous.

DO keep all parts of body and loose
clothing clear of belts, pulleys, and other
exposed moving parts at all t imes.

DO require washing and changing of clothes
if fuel is spilled on a person or his/her
clothing. Keep away from open flames,
sparks, or people smoking.

DO provide a receptacle for catching
product from pump/meter when servicing.

DO clean up product spills on the driveway.
Turn off and lock out all power prior to
cleanup.

DO ensure pump is properly grounded.
DO ensure hose is compatible with fluid

being dispensed.
DO inspect hose, nozzle, and pump on a

regular basis for wear, damage, or other
conditions which may create a safety or
environmental hazard.

DO make sure all pipe threads are properly
cut and the inside reamed to remove burrs.
Use UL classified gasoline-resisting
compound on all joints of gasoline handling
piping. Sealing compound must also be
resistant to Gasohol (Ethanol and
Methanol). 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.

DO ensure that junction box covers are in
place and properl y tigh tened. Mating
surfaces between the box and cover must be
free of dirt, nicks, and scratches. Properly
plug all unused entries into the junction box.

Section 2

INSTALLATION

INSTALLATION PRECAUTIONS

All tanks and installations m ust conform with all building/fire c odes, all Federal, State, and Local
codes, National Electrical Code, (NFPA 70), NFPA 30, Automotive and Marine Service Station
Code (NFPA 30A) and NFPA 395 codes and regulations.

Plan your installation carefully. 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, prec eding the Table of Contents.
It contains important information regarding the safe use of your pumps.

2. DO install an emergency power cutoff if the pump is used for other than personal use. In
addition to circuit breaker requir ements 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, we recommend that all em ployees be
trained as to the location and procedure for turning off power to the dispensing equipment.

3. DO use breakaway couplings on discharge hose. W hile not required for tanks under 1100
gallons, use is recommended for safety reasons.

4. DO have the pump installed by a competent installer/electrician.

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 f iber glass pipe and fittings according to
manufacturer's specifications and requirements.

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.

MDE-4423B Series 70 and 1800 Consumer Elect Pumps Installation/Operation/Parts ● July 2005 2-1

GASBOY Series 70 & 1820

15. DO NOT use gaskets on covers of explosion-proof type boxes. The sealing compound
found around wires at all j unction box entrances is a requirement of the National Elec trical
Code and should not be disturbed. Tighten junction box covers before replacing panels.

16. DO NOT use knock -out box es or f lexible c onduit f or ins talling this unit. All power and lighting
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. At com pletion of the installation, it is the installer 's responsibility to
ensure that any unused openings are plugged.

SUPPLY LINE - UNDERGROUND TANKS

If you are using an underground tank, pitch the tank away from s uction end. Horizontal runs of
suction line should slope down from the pump toward the tank. Do not exceed an equivalent lift of
12' for gasoline or 14' for diesel to the c enter line of the pum ping unit, including friction resistance
in the suction pipe.

The end of the suction pipe must be at least three-inches from bottom of tank.
The tank or piping should not be located under traffic areas. Swing joints (two ells) will prevent

damage to piping due to frost heave or ground settlement.
Use non-hardening, gasoline-resistant pipe c ompound on male threads of all pipe joints for liquid

handling piping.
