for some reason your cyrosurgical unit isn't working properly
and you're not sure how to proceed
we're gonna do some basic
troubleshooting and see if it's an issue
that you can fix yourself or if you need
to send the unit into us for repair
now even though we're gonna use the cryac
for our demonstration you can apply the
same suggestions and guidelines to most
cryo surgical units
the main components of the unit are the
bottle
the lid which includes the nozzle, the stem and the tip
and this is called the pipette
now if you've filled your machine and it's not
working properly the very first thing you
should do is make sure the top matches the bottom
many machines look similar, but there are model variations that may cause machine not to
seal properly 
each cap and bottle are
marked with serial numbers
they can be found on the top here
on the bottom here
and the older models have it etched in the
brass
here
and making sure at the top and bottom match
is the very first step
so you've checked to see that you parts match
but when you squeeze the trigger little
or no nitrogen comes out
the most common problem with these units
is a clogged tip
debris gets stuck in there and blocks the tip
to see if this is your problem simply take off
the tip
and give your unit a squeeze
if you get a nice stream
you've diagnosed your problem
from there you just take your tip and using
an air duster give it a couple of quick blasts
you can even look at it through a light visually
and see that it's all clear
if things look good
reattach it
and give your machine a try
problem fixed
of course it isn't always that easy so
from here we're going to have to determine if
your unit is pressurize properly 
so to do that you carefully 
lift your release valve
and if you can hear nitrogen
escaping then in fact you unit is
pressurizing
chances are the problem lies within the
nozzle
the interior chamber may have become
clogged and you will have to send the
unit into us for repairs 
remember to send us the whole unit even the tip that
you used
for proper diagnosis and repair
if you lift the relief valve and no nitrogen escapes
your unit is not
pressurizing properly and a very common
reason for that is that the gasket is
bad
which is good because in most cases it's a
simple and inexpensive repair
you can order and new gasket from Delasco
and repair it with your fingers 
the gasket comes out and goes in
pretty easily
once you've replaced a gasket give your machine a try
hopefully that fixed the problem
if replacing the gasket doesn't fix the issue
your machine may have vacuum failure
again you are going to have to send it into us for
repair 
before we review the steps of
troubleshooting let's talk about some
other frequently asked questions
hissing, the cryosurgery units are made to vent on their own 
to prevent pressure build-up
it is normal for them to hiss 
as this venting occurs 
the release valve will
also open as a safeguard if the unit
tips over
 icing up
if there's moisture in the micro-climate
where you are using your machine
it's normal for the stem and the top
to ice up
the unit acts like a magnet and will attract
all available moisture from the air
and shouldn't interfere with preformance
the battle however is a insulated vacuum 
chambers and should never be to cold
to touch
if it is there's a problem you vacuum
has failed and the machine is no longer
usable
chances are the bottle can be replaced
and may still be under warranty you'll have
to check with your specific unit and
manufacture for the specific details
Ok, let's review the steps to take if your
machine is not working properly
first make sure that that serial numbers
on the top to bottom match
second, check the tip and see if it's clogged
third, see if you're getting pressurization
by checking the release valve
and fourth
try a new gasket
hopefully we're able to save you some time and
money and get you back to treating
patients
if not you'll have to ship your machine
back to us, but before you do make
sure you watch the quick before you ship
video it has some really relevant
information that will help expedite the
process
