RESPONSIBILITIES
•Employees must enforce compliance
with the safety warnings and all other
instructions contained in this manual
and all federal, state and local
warnings/instructions.
•Keep this manual available for use by all employees
and/or customers.
•For personal safety and proper operation of this
equipment, read and follow all these instructions
carefully.
GENERAL REQUIREMENTS
•This nozzle is designed for use only at facilities
dispensing motor fuels.
•High flow rates in excess of the regulatory allowable may
result in splash-back or spillage. Damage and/or injury
may result.
•Nozzles shall be used in accordance with local and
national safety codes.
•OPW products should be used in compliance with
applicable federal, state, and local laws and regulations.
Product selection should be based on physical
specifications and limitations and compatibility with the
materials to be handled. OPW makes no warranty of
fitness for a particular use.
BEFORE AND DURING FUELING
•OPW recommends posting the following warnings in a
visible location for the fueling public. Additional warnings
may be required. Please contact authorities having local
jurisdiction for requirements.
WARNING
Static electricity, fire hazard, and chemical
exposure hazard. Failure to comply to the
following warning could result in property
damage, injury or death.
•Turn off your engine before refueling. Vehicle must
remain off during the entire fueling procedure.
•Discharge your static electricity before refueling.
•Before using the dispenser, touch any grounded metal
on the car or dispenser away from the nozzle and your
vehicle’s fuel pipe with bare hands. This will discharge
static electricity on your body. Failure to discharge may
ignite petrol vapours.
•DO NOT re-enter your vehicle while refueling. This can
re-charge your body with static electricity. If you must re-
enter your vehicle, discharge static again before
touching the nozzle.
•DO NOT fill containers in or on the vehicle. Static
electricity can ignite petrol vapours and cause a fire. Fill
approved portable containers on the ground. It is
dangerous to put petrol into an unapproved container.
•Keep nozzle in contact with the container until finished
filling to discharge any static generated during fueling.
•When filling an approved portable
container, flow fuel at low flow rate to
prevent static build-up. DO NOT put
trigger in rack position; manually hold
open.
•Turn off cell phones and other
electronic devices to avoid
distractions.
•DO NOT smoke or allow open
flame/sparking devices near the
product dispensers.
•Extinguish all pilot lights and open
flames. For example, the pilot light in
a motorhome or caravan must be
extinguished.
•If a fire starts, DO NOT REMOVE
THE NOZZLE FROM THE FILL
PIPE. Back away immediately and tell the attendant. If
no attendant is on site, use the emergency shut-off
button to stop the pump.
•DO NOT start engine during refueling. Vehicle must
remain off during the entire fueling procedure.
•DO NOT leave nozzle unattended. Nozzle performance
and the automatic shut-off feature are influenced by
many factors. If nozzle does not shut off during refueling,
stop pump immediately.
•DO NOT use foreign objects to hold open automatic
nozzles. Use of foreign objects could result in failure to
shut off.
•Fuels can be harmful or fatal if swallowed. Long-term
exposure to vapors has caused cancer in laboratory
animals.
oAvoid prolonged breathing of vapors.
oKeep away from eyes and skin.
oFailure to use caution may cause serious injury,
illness or death.
•DO NOT allow children to dispense fuel. Only persons of
license age (of legal driving age) should use dispenser.
Keep children away from the dispenser area.
INSTALLATION INSTRUCTIONS
•Before beginning installation of the
product, please carefully read all
warnings.
•Failure to comply with warnings could
result in property damage, injury or
death.
•Do not use power tools (Hazardous location: Zone 1
and/or Zone 2) during installation process and
maintenance of equipment.
•Always wear appropriate safety equipment during
installation or maintenance of equipment.
•Do not install unlisted ad/billboard or other unlisted after-
market device on any automatic nozzle. Doing so may
change the sensitivity of the shut-off mechanism. Nozzle
may not shut off, causing a fuel spill.
•Follow all manufacturers’ instructions.
•Use safety cones to mark-off work area.

•Shut off power to the dispenser and close the
emergency shut-off valves under the dispenser. Relieve
system pressure before servicing or replacing dispensing
products, such as nozzles, swivels, or breakaways.
•Refer to the most recent edition of National Safety
Standard.
•If nozzle replacement, secure retractor before removing
the nozzle.
•If nozzle replacement, remove old
nozzle with a wrench. Carefully
drain fuel from hose & nozzle into
approved container.
•For a new facility installation,
purge/flush hose point before
installing nozzles. If nozzles are used to purge/flush
system, this could result in foreign material in nozzle’s
main valve and cause a nozzle not to shut off.
•Verify selection of nozzle for application.
•Do not use pipe sealant or PTFE
tape on the inlet threads of the
nozzle.
•Engage the external thread into the
swivel or breakaway and tighten
the hose nut per hose instructions.
•Flow test nozzles before putting nozzles in service. See
testing instructions.
•Check continuity. See testing instructions.
•Check for leaks between all connections of hanging
hardware. Repair or replace, as required, if any leaks are
found.
•Dispenser modifications may be necessary for proper
nozzle storage. Always comply with the dispenser
instructions and local codes.
•Register your OPW product at www.opwglobal.com
•After installation, each nozzle should be tested for proper
operation prior to being put into service.
EQUIPMENT REQUIRED
•Stopwatch, approved 20 L grounded, vented, metal test
container, and megohmmeter.
CONTINUITY TEST
•After installation of hanging hardware and prior to flow
test, check continuity following EN 60204-1 for proper
test equipment and method of testing.
WARNING
Fueling equipment is designed to operate in a
pressure range of 0,5 to 3,5 bar. If the pressure
exceeds 6 bar, the nozzle will open regardless of
lever position. Exceeding maximum pressure may
result in property damage, injury, or death.
FLOW TEST
•Start stopwatch, initiate flow into an approved test
container, with the nozzle lever held in the fully open
position.
•Check each hose point to verify a minimum flow rate*
and maximum flow rate**:
Model(s)
Maximum
Flow Rate
Minimum
Flow Rate
21A, 21B
80 L/min
8 L/min
21AP, 21BP
55 L/min
8 L/min
21ADB,
21ADBM 40 L/min 8 L/min
21H
140 L/min
14 L/min
If hose point does not comply, check system and repair
prior to putting into service.
*Minimum flow rate must be met in lowest hold-open clip position. If
hold-open clip is not present, minimum must be met in fully open
position.
**Maximum flow rate must not exceed when nozzle is in highest clip
position or in the fully open position.
WARNING
STATIC ELECTRICITY/FIRE HAZARD
Maintain contact between the nozzle spout and
approved test container during flow test.
SHUT-OFF TEST
•Start flow into approved test container; place nozzle in
low clip position.
