6. Pull Handles all the way back and toward you to release the
nozzle from the receptacle. Remove the nozzle and hang or
store in a safe place. Protect the front end of the nozzle and
keep it clean.
Note:
If you experience difficulty depressing Stop Assembly see
Trouble Shooting Guide.
NOTICE
Important to note that the nozzle operator must maintain
control of the handles during connecting and disconnecting
of the nozzle and the receptacle. Failure to do so will result
in shortened service life of the nozzle.
Uncoupling Nozzle after Fueling:
4. Once the gases vent out of the nozzle from the exposed vent
holes until the venting stops (usually just a few seconds).
If gases continue to vent for a prolonged period of time, check
to make sure handles are fully back and both the nozzle and
receptacle seal poppet’s are closed and LNG is no longer
flowing.
5. Once gas has stopped venting out of the holes, press the stop
Assembly Lever.
CAUTION: DO NOT pull the handles back while pressing
the Stop Assembly Lever.
Note:
If you experience difficulty depressing Stop Assembly see
Trouble Shooting Guide.
Product Maintenance and Part Replacement
Maintenance Schedule
All Macro technologies products are thoroughly tested to prevent
injury and malfunctions during use. The following schedule is
provided as a recommended maintenance guideline to ensure
operator safety and continued smooth and proper nozzle operation.
Each Fueling:
Before and after each fueling thoroughly clean the nozzle and
receptacle opening of any debris or contamination with clean
filtered dry compressed air or dry nitrogen.
Every 8,000 Fills or recommended that station operator
establish a service interval for their specific operating
conditions:
Replace the Receptacle Interface Seal (p/n 14591). The part
normally should last through thousands of cycles depending on
Various environmental factors which can impact seal life. Always
use clean fuel and take care to blow off with dry nitrogen or dry
compressed air both the mating parts inside of the receptacle and
inside around the nose of the nozzle.

Receptacle Interface Seal Replacement or As-Needed
(if leakage occurs while disconnected):
Replace the Seat Assembly and Poppet Assembly (p/n’s 14255
and 13960). These parts normally should last through thousands
of cycles unless excessive amounts of dirt, grit or contaminants are
present. Always use clean fuel and take care to blow off with dry
nitrogen or dry compressed air both the mating parts inside of the
receptacle and inside around the nose of the nozzle.
As-Needed (if bypassing the vent position):
Contact your service department or the manufacturer about
repair options. The Stop Assembly and probe shoulder are
mechanical devices that will eventually become inoperative due to
wear, corrosion and aging of components. The environment and
conditions of use will determine the safe service life of these parts.
Periodic inspection and maintenance are essential to avoid serious
injury and property damage.
NOTICE
•
Dirt, grit or contaminants will cause premature wear
and leakage.
•
The vent holes in some manufacturer’s receptacles
may be sharp and/or contain burrs, if so they may
cause premature seal failures.
•
NO lubrication should be used on the nozzle. If
lubrication is used, it could impair the operability of
the nozzle.
•
If the Stop Assembly does not function properly,
contact Macro Technologies and arrange to have the
CryoMac3 returned and repaired.
