12. Warrantee & Repairs
All units carry a warrantee against manufacturing defects for a period of 3 years from the date of purchase. If for any
reason you require your unit to be serviced or repaired the repair must be carried out by a Brymill Authorized Repair
Center.
We do not service devices that are older than ten years since the parts are no longer available in inventory.
If repairs are performed by any other party the warrantee will become invalid. Unauthorized repairing will also absolve
Brymill Cryogenic Systems of any claims for injury caused by an unauthorized repaired unit. A list of Brymill Approved
Repair Centers is detailed on the web site.
If a repair is needed carefully sanitize and package unit in a protective carton.
13. Troubleshooting
13.1 Problem
If the Cryosurgical Unit does not spray or sprays only intermittently
Solution
Spray Tip may be clogged. Remove tip. If the Cryosurgical Unit sprays without a tip, clean the opening of the tip with a
fine needle or bang the tip gently on a table or counter to dislodge any foreign matter. Then check the Liquid Nitrogen
supply for contaminants that can clog the tips and unit. (see Section 5, Liquid Nitrogen, paragraph 2 for information on
how to keep Liquid Nitrogen supply clean).
The Unit has been over filled and there is insufficient air space inside the bottle to create an adequate build up of pressure
to enable that is required for the Liquid Nitrogen to spray.
Check that the Gasket is in place inside the cover and is not split or missing. Always ensure you have spare Gaskets
available.
13.2 Problem
Trigger Handle sticks open
Solution
Valve Stem sticking. Depressurize the unit immediately by unscrewing the top a quarter to one half turn. Lubricate valve
stem as detailed in Section 8 Maintenance.
13.3 Problem
Unit appears to be “Leaking” or “Hissing” from the Relief Valve.
This may or may not be a problem and depends on the following conditions.
Solution
During normal operating conditions, if the Unit is left standing for a period of time the constant evaporation of the Liquid
Nitrogen inside the bottle will result in the temporary opening of the Relief Value venting the excess pressure. This
“hissing” is also heard when the Unit is picked up. THIS IS NOT A PROBLEM. The Relief Valve is just operating as
designed.
If you experience any problems with your Cryosurgical Unit contact an Authorized Repair Center immediately.
