GENERAL/SAFETY
1. GENERAL
The LPG fueling nozzles are designed to be used for filling LPG vehicles in an operating temperature range of -40°C to 85°C (-40°F to
185°F).
Nozzle type Receptacles type Lock release type
OT300 models Italian type dish coupler Button on side of lever
OTA-300 models Button on side of lever
BNA-300 models Push button on body
Note: due to the difference in receptacles types, nozzles can only connect to one type of receptacle.
The pumping system needs to be switched off prior to connection and disconnection. These nozzles have a design feature to vent any
trapped LPG gas/vapor betseen the vehicle coupler and the nozzle exhaust valve. This feature depends on proper operation of the nozzle
and the pumping system.
These nozzles are only intended for operation at the following service temperatures:
Nozzle type Maximum service pressure Nominal service weight LPG discharge on discon-
nection
OT300 models 24 bar (350 psi) 1.45 kg (3.1 lbs) 4.3 cm3
OTA-300 models 24 bar (350 psi) 1.45 kg (3.1 lbs) > 1 cm3
BNA-300 models 24 bar (350 psi) 1.55 kg (3.41 lbs)
1.6 kg (3.52 lbs)
> 1 cm3
All OPW series nozzles require special installation precautions to ensure safe and reliable operation. The installation shall confirm to the re-
quirements of the authorities having jurisdiction. In absence of requirements, the installation shall comply with standards for LPG vehicle
fueling systems.
OPW products should be used in compliance with applicable European, national and local laws and regulations. Product selection shall be
based on physical specifications and limitations, and compability with the environment and material to be handled.
OPW reserves the right to change specifications at any time without incurring obligations.
2. SAFETY

INSTALLATION
3. INSTALLATION
The inlet and seal for these self-service nozzles are as follows:
Nozzle Inlet
OT300 models
1” Gas (1”-11 BSPP)
In compliance with ISO 228-1
OTA-300 models
BNA-300 models
All O-rings are suitable for use in LPG environments at stated operating temperature.
Adaptor Inlet Outlet
OT321 3/4” Gas female 1” Gas male
1. Make sure that the correct size sealing O-rings are mounted on the male fitting (1” Gas or 3/4” Gas) according to the fitting
and O-ring manufacturers instruction. It’s recommended to use a Buna (NBR) rubber compound specified for use with LPG,
and all compressor oils including synthetic oils. An O-ring with durometer from 70-90 Shore“A” is preferred. OPW provides
proper O-rings with all new nozzles and adaptors.
2. Only connect LPG nozzles to certified hoses according to EN1762.
3. Turn off pumping system, follow good safety practices. Lock and tag out system during installation and repair of fueling
nozzles.
4. Make sure that all sealing surfaces on nozzle and hose are clean, smooth and free from other containments.
5. Check O-ring inside the end of the nozzle and end of hose. O-rings can not be torn, knicked, twisted or have any other
discontinuous feature.Both O-rings must be replaced after each disassembly. Make sure you lightly lubricate them before
installation. Use greasing compatible with LPG.
6. The nozzle hose connection should be tightened according to the following:
Nozzle type Type of wrench Torque required
OT300 models
38 mm (1½”) 27 Nm to 40 Nm (20 ft-lbs to 30 ft-lbs)
OTA-300 models
BNA-300 models
1” Gas (1”-11 BSPP) 3/4” Gas (3/4”-14 BSPP) Adaptor OT321

INSTALLATION/OPERATION
7. After installation, test the unit for leaks. The lever should be cycled a few times. Pressurize and test connection using a suit-
able leak detection. Test pressure should include low pressure, under 5 bar (75 psi) and up to the maximum service pressure
of 24 bar (350 psi).
4. OPERATION
1. Make sure that you have the correct receptable for the specific nozzle type.
2. Remove receptacle dust cap, check receptacle functional status and look for any debris or dirt.
3. Remove the nozzle from the rest position and make sure that the lever is extended forward. This retracts jaws on Italian dish
coupler and extends clamping sleeve on all models.
4. Verify that the outlet gasket is present and fully inserted.
5. Initial connection position:
On OT300 models and OTA300 models:
Squeeze the lever (1) and then slide the lock release (2) to
the side to allow the lever to move forward (3).
On BNA-300 models:
Squeeze the lever (1) and then push the lock release but-
ton (2) to allow the lever to move forward (3). Then release
the lock release button.

6. While lever on the nozzle is forward, the nozzle is inserted into the Italian dish coupler.
7. Squeeze lever until the latch engages and locks the nozzle into place.
8. If the nozzle lever will not connect, or nozzle won’t lock into place, make sure that the supply hose and pumping system are
unpressurized and the pumping system is “OFF”.
9. Make sure the nozzle is connected properly and firmly attached to the vehicle receptacle.
10.Turn the station dispenser “ON”. The vehicle is now being refueled.
11.When fueling is complete, turn the station dispenser“OFF”.
12.Release the nozzle locking latch.

OPERATION/MAINTENANCE
13.After lock latch is released, push or allow lever to move forward.
14.After the latch is released the nozzle can be pulled straight back and out of dish coupler. Nozzle can be returned back to
restore position.
15.Put nozzle back to resting position on LPG dispenser in a clean protected area.
16.Put receptacle dust cover back on the vehicle.
NOTE: There will be a slight venting of gas during disconnection. This is normal and should only be small and brief.
If the vent is long and continuous, the main check valve in the nozzle is not working properly. The nozzle needs to be returned to a certi-
fied repair center for maintenance immediately.
5. MAINTENANCE
These self service nozzles must be kept in a clean and protected area. The nozzle must not be exposed to debris, dirt, water or chemicals.
Service life is dependent on handling and care of nozzles.
Unusual operation must be reported to the service represenative immediately.
Routine maintenance:
1. Inspect the jaws and clean any dirt, grease or oil from the front gasket and jaws using a lint free cloth. Do not use any sol-
vents as this may degrade the seals performance integrity and create a risk for personal injury with subsequent use.
2. The entire nozzle should be cleaned and moving parts lubricated periodically by fueling attendant or service personnel.
This should occur on average once per six (6) months or more frequently if the nozzle is constantly in use or is used under
extremely dirty conditions. Grease moving parts with grease compatible with LPG.
3. The lever mechanism, latch, jaws and swivel should all move freely. These should be checked for proper operation daily. If
any parts are not operating properly, contact a service representative immediately.
4. The front gasket should be replaced by stage of wear.
After two (2) years of service:
The unit should be returned to a qualified repair center for a replacement of all seals and worn parts. This period should be reduced to
twelve (12) months or less, if there is a risk that the nozzle has been misused, abused or if the nozzle is used in extreme environmental
surroundings.
Special tools and care are required to clean and repair/rebuild elements of the nozzle. Due to safety and performance reasons, only quali-
fied technicians can service the nozzles.
Only OPW original spare parts, seals and sub-assemblies are allowed to be used during the service of any OPW LPG product.
